  • http://www.chinawanjintong.com/The Coil Coating Process: Prepainted Steel And Aluminum Coil coating refers to the process of creating prepainted steel and aluminum. Prepainted steel or aluminum can be found in a high number of household products. From refrigerators to air conditioners and construction material, prepainted steel can be found everywhere. Different coatings can be applied for different demands.  “In some coatings, you are going to need more exterior environment weathering, flexibility, and more impact resistance than you do with other coatings,” says Aaron Small, Corporate Vice President at Kloeckner Metals U.S. and President of the National Coil Coating Association (NCCA). “If we’re going to do roofing and sidewalls, we would often choose either a fluorocarbon, siliconized polyester, or modified polyesters.”  Coil Coating: The Basics  Coil coating is how the coating material is applied to the strip of steel or aluminum. A coil of metal sheet is continuously fed into the process which is controlled via accumulators at each end of the line. They take in a bare coil of metal at one end and let out the finished product on the other end. In the middle, the coil coating process is applied.  “What we do is actually referred to as high-speed, continuous coil coating,” Small says. “What makes high-speed, continuous coil coating possible is the non-stop application of the cleaning, the treating, the coating, the curing, and potentially the leveling, while the sheet is flat, all in one high-speed path through a coil coating line.”  The Key to Coil Coating  The key is being able to maintain a constant speed of the strip through the process. The accumulators allow this by letting the middle of the line to continue running at the prescribed rate while new metal is added at the decoil end, or the finished product is removed from the recoil end of the line.  “You don’t have starts and stops,” Small says. “This allows our coaters to consistently clean, treat, seal, apply a paper-thin coating, cure it evenly, and cool it back down without burning the metal or the coating.”  The Uses Of Aluminum Coil Aluminum is a truly remarkable metal. Due to its signature properties (malleability, rust and corrosion resistance, etc.) countless individuals have taken aluminum and have used it for numerous applications. If you are like many, it can be difficult to understand what exactly the uses of aluminum coil are. Do not worry. Wrisco has prepared a small list of industries and practices that rely on aluminum coil to get the job done. So if you are curious to know what the uses of aluminum coil are, then continue reading below.  THE USES OF ALUMINUM COIL  TRANSPORTATION  You might be surprised to find out that the construction of most forms of transportation is actually made with aluminum coil. Transportation vehicles such as automobiles and cars are manufactured from aluminum coils. This is because such vehicles will require components that are lightweight, durable and not rust easily since they will be used daily. Parts of most transportation vehicles that rely on aluminum coil for construction include engine components, air conditioners, radiators, wheel hubs, car doors and much more.  ARCHITECTURAL DECORATION  Thanks to its corrosion resistance, strength, and incredible processing and welding performance, aluminum coil will be often utilized a lot for architectural decoration. Other than surface decoration, most building projects rely on aluminum coil to help design structures, doors, windows, ceilings, curtain wall profiles, pressure plates, color coating sheets, etc.  ELECTRONIC APPLIANCES  Although this metal is not as electrically conductive as copper, aluminum coils are often utilized within many electronics. Aluminum is often particularly used in wiring as their corrosion resistance guarantees that wires will last for a long time. This is why objects such as power lines and air conditioners with electrical components are able to withstand the elements for a long time. This is why most electronics, in general, have a fairly long lifespan.  FOOD INDUSTRY  The main reason why food cans are made with aluminum coils is because of aluminum’s malleability, rust and corrosion resistance. Thanks to its malleability, aluminum cans are able to be easily manufactured in mass quantities. Due to its rust and corrosion resistance, aluminum is able to guarantee that the food within the can will be able to stay fresh for a long time. Besides cans, aluminum coils aid in the production of lid caps, bottles and other packaging.  AND MUCH MORE  Aluminum is such a versatile metal. Because of this, aluminum coils are utilized for a wide variety of reasons. Though we have listed some applications above, there are many more industries and practices that aluminum coils are used for. If you find that you need a metal type to help assist you in the production or function of a certain object or item, you very likely might just benefit from purchasing aluminum coil.  Galvanized Steel: Types, Uses, Benefits What is Galvanizing?  Galvanizing, or galvanization, is a manufacturing process where a coating of zinc is applied to steel or iron to offer protection and prevent rusting. There are several galvanizing processes available, but the most commonly offered and used method is called hot-dip galvanizing.  Galvanized steel is among the most popular steel types because of its extended durability, having the strength and formability of steel plus the corrosion protection of the zinc-iron coating. The zinc protects the base metal by acting as a barrier to corrosive elements, and the sacrificial nature of the coating results in a long-lasting and high-quality steel product.  This versatility makes it applicable to a variety of projects and industries, including agriculture, solar, automotive, construction, and so on. Below, we aim to provide a comprehensive description of how galvanized steel is processed, different galvanization methods, its benefits, and how it is used in these various industries.  The steps in the galvanizing process are as follows:  The steel is cleaned in a degreasing solution  After being cleaned, the steel is pickled by being lowered into a vat of diluted hot sulfuric acid  The steel is then fluxed in an aqueous solution (typically zinc-ammonium chloride)  After the flux, the steel is galvanized through immersion in a vat of molten zinc  Afterward, the steel is inspected for consistency and a complete coating  What are the advantages of galvanized steel?  Many different industries utilize galvanized steel primarily because it has such a wide array of benefits for industries to take advantage of, including having:  Low initial cost compared to most treated steels. In addition, galvanized steel is immediately ready to use when delivered. It does not require additional preparation of the surface, inspections, painting/coatings, etc. sparing companies more costs on their end.  Longer life. With galvanization, a piece of industrial steel is expected to last more than 50 years in average environments, and can last over 20 years with severe water exposure. There is no maintenance required. The increased durability of the steel’s finished product also increases the product’s reliability.  The sacrificial anode ensures that any damaged steel is protected by the surrounding zinc coating. It doesn’t matter if the steel section is completely exposed; the zinc will still corrode first. The coating will corrode preferentially to the steel, creating a sacrificial protection to the areas that are damaged.  Rust resistance from the zinc coating. The iron elements in steel are incredibly prone to rusting, but the addition of zinc acts as a protective buffer between the steel and any moisture or oxygen. Galvanized steel is very protective, including sharp corners and recesses that couldn’t be protected with other coatings, making it resistant to damage.  Different methods of galvanizing  As stated above, there are several different processes for galvanizing steel.  What Are The Strongest Metals? What is the world’s strongest metal? This is one of those questions that sounds simple enough but is actually quite complex. When it comes to metal, making direct comparisons based on strength doesn’t work. Why? First of all, because there isn’t a single, universal scale for strength. At best, there are four. In today’s blog, I’m going to outline these four types of strength as they relate to metallurgy before giving some insights and comparisons of the metals leading the pack in terms of strength. Let’s get started.  DETERMINING THE STRONGEST METALS: TYPES OF STRENGTH  TENSILE STRENGTH  Tensile strength refers to a material’s ability to resist tension. In other words, it looks at the amount of strength required to stretch or pull something apart. A material with low tensile strength would pull apart more easily than a material with high tensile strength.  COMPRESSIVE STRENGTH  Compressive strength refers to a material’s ability to withstand being squeezed together (compressed). To test compressive strength, an external force places pressure upon a material, tracking to what degree the material can resist size reduction. A widely accepted test for compressive strength is Mohs Hardness Test. The test relies on a scale which rates minerals from 1-10, or softest-hardest.  YIELD STRENGTH  Yield strength refers to a material’s ability to withstand permanent deformation or bending. It’s a way of testing the elastic limit of a given material. Usually determined via a bend test where two ends of a beam or bar are gripped and stress is applied. The intent is to discover how much stress it requires to exceed the material’s yield point, or the point at which the material will not return to its original shape upon removal of the stress.  IMPACT STRENGTH  Impact strength refers to a material’s ability to withstand a blow without fracturing or shattering. In other words, it’s a method for determining the limit of how much energy a material can absorb via impact.  What is a Corrugated Metal Roofing Panel? A corrugated panel has a repeating wavy or rippled pattern across its design. It was the first mass-produced metal panel design in the United States. These panels can be used for roofing, siding, decking, and flooring. Corrugated panels are connected by overlapping the sheets, and then securing them in place with exposed fasteners. Trapezoidal rib panels are often mistakenly referred to as corrugated roofing.  The most common corrugated materials include coated carbon steel, stainless steel, aluminum, and copper. Even non-metal materials are corrugated as well. Plastic and fiberglass are corrugated and then used as translucent ceilings or roof lights.님의 프로필 사진

  • http://www.api-onlinestore.com/What Are Nootropics? Whether you\'re a college student hoping to ace your exams, a busy professional striving for a promotion, or an older adult concerned about dementia, the idea of popping a pill that boosts your brainpower might seem pretty appealing. So perhaps it\'s not surprising that the use of nootropics -- aka cognitive enhancers or smart drugs -- is on the rise. ;  The term \"nootropics\" first referred to chemicals that met very specific criteria. But now it\'s used to refer to any natural or synthetic substance that may have a positive impact on mental skills. In general, nootropics fall into three general categories: dietary supplements, synthetic compounds, and prescription drugs.  While health experts generally agree that taking a prescription nootropic for an FDA-approved purpose (such as a stimulant medication if you have ADHD or donepezil if you have Alzheimer\'s) may be helpful, the use of any type of cognitive enhancer in healthy people is far more controversial.   Local Anesthesia Today, many types of surgery can be safely and painlessly performed while you are awake. Local anesthesia, also called local anesthetic, is usually a one-time injection of medicine that numbs a small area of the body. It is used for procedures such as performing a skin biopsy or breast biopsy, repairing a broken bone, or stitching a deep cut. You will be awake and alert, and you may feel some pressure, but you won\'t feel pain in the area being treated.  When is local anesthesia used?  Local anesthetics have made it possible to perform many surgical procedures quickly, with less preparation and a shorter recovery time. General anesthesia and anesthesia that sedates you can cause side effects such as nausea, and a physician anesthesiologist must monitor you if you are administered these types of anesthesia — during the procedure and for a time afterward. However, with local anesthesia, side effects and complications are rare and usually minor. For example, you may experience some soreness where the medication was injected. In rare cases, you could have an allergic reaction to the anesthetic.   Anti Estrogen A substance that keeps cells from making or using estrogen (a hormone that plays a role in female sex characteristics, the menstrual cycle, and pregnancy). Anti Estrogen ;may stop some cancer cells from growing and are used to prevent and treat breast cancer. They are also being studied in the treatment of other types of cancer. An anti-estrogen is a type of hormone antagonist. Also called estrogen blocker.  Antiestrogens, also known as estrogen antagonists or estrogen blockers, are a class of drugs that prevent estrogens like estradiol from mediating their biological effects in the body. They act by blocking the estrogen receptor (ER) and/or inhibiting or suppressing estrogen production. Antiestrogens are one of three types of sex hormone antagonists, the others being antiandrogens and antiprogestogens. Antiestrogens are commonly used to stop steroid hormones, estrogen, from binding to the estrogen receptors leading to the decrease of estrogen levels. Decreased levels of estrogen can lead to complications in sexual development. Antiandrogens are sex hormone antagonists which are able to lower the production and the effects that testosterone can have on female bodies.   Peptides for Bodybuilding: Do They Work, And Are They Safe? Bodybuilding Peptides ;are a popular performance-enhancing aid in the bodybuilding community. Growth hormone secretagogues (GHS) are a type of peptide that attracts particular interest. People often view peptides as a more natural alternative to anabolic steroids and praise them for their ability to boost muscle mass, promote fat loss, and help bodybuilders get the most out of their workouts.  Bodybuilding Peptides are popularly used among bodybuilders which helps in standards of performance. This, along with Growth hormone secretagogues (GHS) are the short strands of amino acids that are found in our body and some sources of plants and animals. An amino acid contains a lesser amount of it than that of proteins. Researchers stated that peptides are essential for anti-inflammatory and anti-aging, and also help in building muscles. These because of their size have the ability to absorb faster and break down than proteins. They can enter the bloodstream quite easily through the penetration of the intestine and skin.   Cosmetic Peptide Cosmetic peptides ;are important ingredients in global cosmetic products and international brands, primarily for anti-aging applications. Peptides have various cosmetic benefits and each peptide used in products has a specific activity; firming, anti-wrinkle, anti-irritation, and reduction in pigmentation. Our long-standing experience in clinical-grade peptide manufacture applies equally to cosmetic peptides. PolyPeptide adapts the quality standards to the cosmetic market needs.   Steroids Hormone Steroids hormone ;is any of a group of hormones that belong to the class of chemical compounds known as steroids; they are secreted by three “steroid glands”—the adrenal cortex, testes, and ovaries—and during pregnancy by the placenta. All steroid hormones are derived from cholesterol. They are transported through the bloodstream to the cells of various target organs where they carry out the regulation of a wide range of physiological functions.  These hormones often are classified according to the organs that synthesize them: the adrenal steroids are so-called because they are secreted by the adrenal cortex, and the sex hormones are those produced by the ovaries and testes. This distinction is not exclusive, however, because the adrenal cortex also secretes sex hormones, albeit to a lesser extent than do the gonads, and the ovaries under abnormal conditions may produce adrenal steroids.   Steroids Injection Steroid injections, also called corticosteroid injections, are anti-inflammatory medicines used to treat a range of conditions. They can be used to treat problems such as joint pain, arthritis, sciatica, and inflammatory bowel disease. Steroid injections are only given by healthcare professionals. Common examples include hydrocortisone, triamcinolone, and methylprednisolone.  How steroid injections work  Steroids are a manmade version of hormones normally produced by the adrenal glands, 2 small glands found above the kidneys.  When injected into a joint or muscle, steroids reduce redness and swelling (inflammation) in the nearby area. This can help relieve pain and stiffness.  When injected into the blood, they can reduce inflammation throughout the body, as well as reduce the activity of the immune system, the body\'s natural defense against illness and infection.  This can help treat autoimmune conditions, such as multiple sclerosis (MS), which are caused by the immune system mistakenly attacking the body.   Pesticides Pesticides ;are substances that are meant to control pests. ; The term pesticide includes all of the following: herbicide, insecticides (which may include insect growth regulators, termiticides, etc.) nematicide, molluscicide, piscicide, avicide, rodenticide, bactericide, insect repellent, animal repellent, antimicrobial, fungicide, and lampricide. The most common of these are herbicides which account for approximately 80% of all pesticide use. Most pesticides are intended to serve as plant protection products (also known as crop protection products), which in general, protect plants from weeds, fungi, or insects. As an example, the fungus Alternaria solani is used to combat the aquatic weed Salvinia.  In general, a pesticide is a chemical (such as carbamate) or biological agent (such as a virus, bacterium, or fungus) that deters, incapacitates, kills, or otherwise discourages pests. Target pests can include insects, plant pathogens, weeds, molluscs, birds, mammals, fish, nematodes (roundworms), and microbes that destroy property, cause nuisance, spread disease, or are disease vectors. Along with these benefits, pesticides also have drawbacks, such as potential toxicity to humans and other species.님의 프로필 사진

Laminated Bags: The Strongest Bag Material Laminated bags ;are super strong and allow full-color processing. Know the details to make the most of this reusable bag fabric.  How Are Laminated Bags Made?  Laminated bags begin with a base layer (substrate) that is white. Then, a thin layer of polypropylene sheeting is printed with four color graphics and laminated on top of the substrate. The top layer is heat bonded for a permanent seal. Panels are precision cut and sewn after printing.   Substrates  Most laminated bags use one of the following three substrates. No matter which one you choose, the four-color graphics in the exterior lamination layer is all the customer will see from the outside. The substrate is only visible on the inside of the bag.  Woven PP For this material, strips of PP are woven together and a lamination layer bonds the weave together. This material is incredibly strong for its weight and is often used for sandbags, tarps, and other industrial uses. This material puckers after 6-8 months as the material ages.  NWPP Lamination gives NWPP a strong, puncture-resistant top layer for a smooth great looking bag. Once laminated, NWPP weighs 120 GSM, making it extra durable and long-lasting. This is a premium choice for grocery bags, promotional bags, or custom bags for any organization.  Recycled PET (rPET) Water bottles are shredded and spun into a substrate fabric to create recycled reusable bags. The lamination sheeting is not recycled, so the final bag contains 85% post-consumer waste. RPET bags are the gold standard in eco-friendly bags, ideal to demonstrate your commitment to the environment.

  • http://www.alasartech-security.com/What is a cell phone signal jammer?  A mobile phone signal jammer ;is a device that blocks reception between cell towers and mobile phones. Developed for use by the military and law enforcement, these devices were originally created to combat threats like cell phone-triggered explosives and hostage situations.  How do cell phone signal jammers work?  Known as cell jammers, signal blockers, GPS jammers, or text stoppers, a cell phone signal jammer holds up the radio frequency in a given area, creating a sort of signal traffic jam that blocks all communication. Like a radio silence bubble, no calls or texts can be sent or received as long as the user is within range of the cell phone signal blocker.  So, why are cell phone signal jammers used?  Proponents of such technology argue that signal jammer devices are necessary for many places where humans just can’t seem to observe the widely accepted rules of proper cell phone etiquette. Think schools, theaters, vehicles, or an otherwise quiet train ride… pretty much any venue were talking, texting, streaming and the like might be deemed disruptive or even dangerous.  Keep in mind, that a mobile signal jammer will not only block voice and text on your phone, it also interferes with GPS, WiFi, and probably most problematic of all — police radar. That’s why, as mentioned above, the Federal Government has banned the sale, promotion, and use of cell phone signal jammers in the US. So if you were envisioning a little peace and quiet, courtesy of a shiny new signal blocker, you might just have to settle for earplugs.   RCIED JAMMER The RCIED jammer ;is based on the advanced technology of reactive jamming and is specially designed to defeat Remote Controlled Improvised Explosive Devices (RCIEDs).  The RCIED jamming systems meet challenges from hostile conditions and are characterized by nonstop operating capabilities, rapid field installation, and disassembly.  The innovative technology of reactive jamming guarantees the highest level of efficiency for radio signal detection and disruption in real-time in both urban and suburban areas.  The wideband RCIED jammers are activated within milliseconds and assure 100% protection against radio-controlled improvised explosive devices.  Nowadays different kinds of transmitters, radios, and even mobile phones can be used to remote control bombs and other explosives. All of them have different characteristics of channel size, modulation and output power. That’s why it is crucial that the jamming signal is created and adapted individually and covers each radio frequency waveform precisely. In other words, the design and software of the RCIED jamming systems should provide the ability to create jamming signals without any limit, which means that any modulations or adapted RF waveforms can be generated.  The RCIED jammers have extended programming features, they are fast to set up and easy to use, have external batteries for autonomous operation, and can be easily transportable.  The main advantage of the RCIED jammers is a programmable signal generation that assures precious adaption to the different adversarial signals.   Drone Jammers: How They Work, Why They Exist and Are They Legal? It\'s not a secret that not everyone is ecstatic that there is a growing number of drones taking off to the skies nowadays. As with just about any piece of technology, there are drone pilots who use their drones less responsibly or more maliciously than others. With the growing concerns over privacy and security, it\'s not a surprise that there have been a lot of efforts to develop drone jammers.  These anti-drone technologies have common goals – to bring down a rogue or prevent them from entering a restricted area. How are drone pilots supposed to feel about this relatively new development? Do we need to watch out for our neighbors taking down our drones with their own drone jammers?   Are drone jammers necessary?  Despite efforts by the FAA and the NTSB to regulate drone flight, it cannot be denied that they have been and continue to be used for purposes that are malicious, unethical, or downright illegal. Cases of drones being used for voyeurism are incredibly common, with a few well-documented cases highlighting just how disturbing drones can be in the wrong hands. They have also interfered with emergency response operations, caused delays in commercial flights, and used to smuggle contraband into correctional facilities.  In 2015, a drone was able to fly onto the lawn of the White House – one of the strictest permanent “no-drone zones” in the country. This event proved just how drones can be when used to breach security, as they are too small to be detected by standard radar equipment.  Although the pilot responsible for the drone was only flying for fun and claimed to have lost control of it, the incident opened the national consciousness to the dangers of drone use. After all, the lawn where the drone was recovered was the same lawn where the presidential helicopter lands. Without security measures, it would have been easy to mount an attack using the drone.  With public safety and national security on the line, it really was only a matter of time before anti-drone technology was developed. Are they necessary? Arguably, yes, they are – at least, until a more comprehensive method for implementing accountability for drone pilots can be created. However, anti-drone technology must also be similarly regulated.   How do drone jammers work?  Short of shooting down a drone with physical projectiles, the only anti-drone technology in existence is what is commonly known as a “drone jammer.” As its name implies, such a device will jam the frequency – either 2.4 GHz or 5.8 GHz – that a drone uses to communicate with its ground station. The drone jammer does this by sending its own electromagnetic signal at the same frequency, thus overriding the drone’s communication systems. In most cases, this will result in the drone activating its Return to Home function, through which the drone pilot can be identified.  This description may conjure images of a drone jammer that looks like a gun, but this may not necessarily be the case. True enough, there are handheld drone jammers in existence. However, these are heavy and bulky devices that take a lot of effort to deploy and can hardly be used stealthily. More commonly used are perimeter-based drone jamming technologies that use signal emitters placed around an area that needs to be protected from drone intrusion.   Mobile phone jammer A mobile phone jam ;or blocker is a device that deliberately transmits signals on the same radio frequencies as mobile phones, disrupting the communication between the phone and the cell phone base station, effectively disabling mobile phones within the range of the jammer, preventing them from receiving signals and from transmitting them. Jammers can be used in practically any location, but are found primarily in places where a phone call would be particularly disruptive because silence is expected, such as entertainment venues.  Because they disrupt the operations of legitimate mobile phone services, the use of such blocking devices is illegal in many jurisdictions, especially without a license. When operational, such devices also block access to emergency services.   Remote Control Jammers And The Way They May Be Useful The remotes jamming devices are really nice tools and here we will try to explain to you a couple of things about them. The first thing here is the fact that the remote control jammer ;can be considered “friendly” unlike most of the other blocking devices. Unlike the other blocking devices such as cell phone signal zappers or GPS blockers, the remote control zappers can be used mostly for pranks and fun. This is why we don\'t understand why lots of countries have banned their usages like the usage of mobile phone zappers or even GPS scramblers.  A really interesting fact about remote control signal zappers is the fact that they are actually fairly new to the market and now, even if you want to buy a new device, you will have to know that their prices are a bit higher. Anyway, if you want to buy such a device it will be better to know a couple of things about it. This is why would like to recommend you to read as much information as you can find on the internet about those devices because it is always better to know a couple of things about the technology you are about to own  As we said in the beginning it is pretty important to know that you might have problems with the authorities owning one of those devices and this is why you need to check your local laws. Also, you should check the frequencies used in your country for remotes and the frequency of the remote that you want to jam. ;님의 프로필 사진

  • http://www.douruytool.com/CNC End Mill Comparison Guide There are many different factors that go into the objects you can create with a CNC mill, but the biggest contributor is going to be your CNC end mills. At the most basic level, end mills are like drill bits but instead of only drilling vertically, they can also cut horizontally and have several form factors to get the cleanest cut for specific materials. Some are used only for plastics to keep from heating too much, some are designed to keep wood from chipping or tearing out, and some are designed for ultra-fine detail work. ;   Shape  From one end mill to the next, the most obvious difference you will find is that end mills come in many shapes and sizes. Some are thin and pointy, and others are wide and rounded. Some of the most common shapes you will find are fishtail (or flat), ball-nosed, and the bullnose, and each of these can be a straight cut or a tapered cut.   Size  Size is the biggest determination of what you can do with any given end mill. Large ones excel at grinding through a lot of material at once, but you don’t get a lot of detail out of your parts. With CNC milling, the radius of your end mill is the radius of any internal corner, so you will almost never have a perfectly square corner on the inside of a milled object. Smaller and smaller end mills can be used for each pass to clean up an edge and get the part to the final dimension and shape. ;   Straight vs. Tapered  There are generally two forms of end mills: straight and tapered. This is a choice based on the geometry of your finished part because a tapered end mill won’t be able to do all the same things as a straight end mill, and a straight end mill may not be the most efficient choice. By using a tapered end mill, the cross-sectional area is larger than a straight end mill of the same tip diameter, creating a much stronger end mill that is less likely to bend while milling. For perfectly vertical walls you will need to use a straight end mill as the taper just won’t reach. However for angled walls, using a straight end mill is not the most efficient, ideal choice.   Why Use a Single Flute End Mill? There are a lot of strange beasts out there in the cutting tool world and a lot of physics that are not obvious. For example, many machinists will know that more flutes mean more productivity, but that certain materials, like aluminum, require fewer flutes–usually two or three. If that\'s the case, when would it ever make sense to use 1 flute end mill? Is there a time when the least number of flutes possible is a good idea?  Now let\'s take a CNC Router example. ; Say it\'s got a spindle capable of 24,000 rpm, but it will go no slower than 12,000 rpm. ; When cutting aluminum, the first thing we discover is we need carbide to run at those surface speeds–preferably a good coating is needed to up the limit even more. As we begin working through the feeds and speeds (hopefully using G-Wizard Calculator!), we discover we\'re going to need some pretty high feed rates at those RPMs too. ; For a 1/4″ endmill, it wants to run at 24000 rpm and a feed rate of about 255 IPM. ; ;Now depending on the machine, we may have discovered a problem. What do we do if our machine can\'t feed that fast?  The answer is to use a 1 flute endmill because it halves the necessary feed rates without rubbing. So there is one case where it helps when the machine just can\'t feed fast enough to keep up with what the spindle is putting out and maintain adequate chip loads.   FINISHING END MILLS-2 FLUTE Finishing End Mills are used in metalworking applications for removing material or burrs from a workpiece and leaving behind a smooth finish. 2 Flute End Mills ;are used for center cutting (plunge cut) operation and when chip removal in slots and grooves is a problem. A wide range of coatings such as Titanium Nitride (TiN), Titanium Carbon Nitride (TiCN), Titanium Aluminum Nitride (TiAlN or AlTiN), and Diamond finishes permit maximum performance and value for a particular application or material. Both standard and metric shank and cutting diameters are available.  Uncoated High Helix Single End Mills from TTC Production. These HP series of single-end mills are exclusively designed to work on aluminum workpieces. TTC\'s HP series are available in two-flute, spiral designs and come in regular, long, and extra-long lengths. The tool is made from high-speed steel and the center cutting makes it suitable for peripheral, ramping, helical, plunging, and slotting operations. The high helix angle wraps around the tool faster and provides excellent chip evacuation at high speeds. ;   3 Flute End Mills - Carbide, Cobalt & HSS Three flute end mills ;are used for higher feed rates than two flute end mills and are often used in aluminum machining. ; They are commonly used in grooving operations where the chip is crowded. ; They are also used in non-ferrous milling applications where high feed rates are used. ; Three flute mills tend to reduce vibrations during the cutting operation. ;   PCB Corn Teeth End Mill PCB Corn Teeth End Mill is suitable for printed circuit board (PCB), high-density fiberboard (HDF), super hardwood, carbon fiber, fiberglass, HDF composite board, bakelite plate, epoxy board, shell, or powder materials.  Features of ;PCB Corn Teeth End Mill  1. Special Cutting Edge: Special cutting edge can increase the cutting ability. The lifetime of tools and machines will be longer  2. Smooth And Wide Flute: Smooth and wide flute will remove the cuttings more easily  3. Heat-resistant Coating: With highly heat-resistant HELICAL coating, can be used for high-speed processing  4. Bronze Coating: Under bronze coating, any abrasion is easy to be recognized  5. High-Quality Raw Material: The raw material is used of high toughness, grain-sized carbon tungsten  6. Polished Surface Treatment: With high polished surface treatment, the friction coefficient could be reduced, the lathe efficiency could be improved, more production time could be saved   The Bits Now when it comes to the actual engraving bits, there are an incredible amount of different types. However, in this article, we\'ll simplify things and go down to two basic ones - metal and Plexi.  For steel/aluminum engravings, I always use diamond bits since these give a great result and they are very durable. There are all kinds of different sizes but there are three basic bits that get you started in a good way.  When doing plexiglass engravings you can use the diamond bits, but I like to use a different kind of bit since I like to play around with different textures. Therefore, I use a cutting bit, instead. Since the Plexi is a lot softer than metal, you can do some very cool things indeed with cutting bits.   Drill Bits Drill bits ;are grouped into two categories: roller cone and drag (Fig. 11). Roller cone bits are of two types: milled-tooth and insert. They are designed to drill rocks of various types and strengths. The milled-tooth bits are generally used when tooth wear is not a critical issue, whereas the insert bits with tungsten carbide inserts are used when tooth wear becomes the limiting factor in the life of the bit. Both the milled-tooth and insert bits have bearings wear that limits their operating lives. The rock-cutting mechanisms of roller cone bits use a shoveling (gouging) action in soft formations and a crushing (chiseling) action in hard formations. Drag bits are of two types as well: polycrystalline diamond cutters (PDCs) and diamond matrix bodies. The major differences from the roller cone bits are the rock-cutting mechanisms and a lack of bearings. The PDC bit cutting mechanism is rock shearing, whereas the diamond matrix is rock grinding. PDC bits are used in all nonabrasive rocks regardless of strength, whereas the diamond matrix bits are generally used in extremely hard abrasive formations. Drill bit selection is based mainly on past bit performance records. Past experience and learning are key factors in selecting the right bit for the right hole interval to be drilled.   Choosing and Using the Right Router Bits for Woodworking Walk into any fine woodworking supplier and you\'ll likely find a wall covered with hundreds of different router bits of different profiles, shank sizes, tip types, and more. A woodworking router bit is one of the most versatile woodworking tools you can own, but it\'s not the tool itself that brings versatility; it\'s the bits. Choosing the right router bit and using it properly involves selecting the right style and size of bit for the job as well as installing the bit correctly and using an appropriate tool speed.  Woodworking router bits come in a variety of sizes. To ensure safety and the best possible results from your routing, you must adjust the speed of the router to suit the diameter of the router bit. The general rule is the larger the bit, the slower the maximum allowable router speed.님의 프로필 사진

  • http://www.ykaoyujx.com/Three Reasons Why You Should Use a Chipper Shredder No matter the region, winter weather can leave your lawn with a combination of fallen branches, leaves, and other debris. A chipper shredder ;or a chipper shredder vacuum is a great solution to help clean up and revive your yard.  The purpose and benefit of these tools are to make it easy to dispose of yard debris like leaves, small branches, and twigs, which can also be used for other lawn needs. However, unlike a chipper shredder, a chipper shredder vacuum has the maneuverability of a walk-behind mower, letting you get to those hard-to-reach areas with a vacuum hose.  In addition to their basic functionalities, here are three other reasons why you should use a chipper shredder or chipper shredder vacuum.  Time-saver:  Not only do these tools help remove twigs and leaves from your yard, but they also can transform 10 bags of debris into one for an easy cleanup process. This will help you cut down on time and space.  Mulch:  Use the chipping functionality to turn twigs and small branches into fine wood chips for your own nutrient-rich mulch.  Compost:  The shredding component of chipper shredders and chipper shredder vacuums provides the option to compost leaves and plants in a timely manner. Rather than taking a few months for elements to decompose, the decomposition process is sped up because more surface area is exposed with smaller pieces.   Scythe Mowers Scythe mowers, sometimes known as sickle bar mowers, are ideal for cutting down long grass and overgrown areas. Traditionally, scythe mowers were used by smallholders to make small amounts of hay.  Sickle bar mowers will tackle long grass in paddocks, orchards, and around buildings with ease. The large reciprocating blade will quickly cut through brambles, nettles, and tough grass with ease.  One of the advantages of a scythe mower is the fact that it takes very little power to drive the cutter bar. With a rotary mower, you are dealing with a lot of grass going through the machine which tends to put the engine under load. With a scythe mower, the machine has almost a scissor-type cutting action, which cuts the grass effortlessly and cleanly.  Machine sizes vary from 24-inch cut models to the larger 48-inch models. We have a selection of machines from budget machines to machines for the contractor and keen gardener. Scythe mowers have come a long way since the old Allen scythes and Mayfield scythe mowers. I think many people have the experience to share regarding their old Allen scythe and the temperamental clutch!   Multi-function Lawn Mower Multi-function Lawn Mower (also known as a mower, grass cutter, or lawnmower) is a machine utilizing one or more revolving blades to cut a grass surface to an even height. The height of the cut grass may be fixed by the design of the mower, but generally is adjustable by the operator, typically by a single master lever, or by a lever or nut and bolt on each of the machine\'s wheels. The blades may be powered by manual force, with wheels mechanically connected to the cutting blades so that when the mower is pushed forward, the blades spin, or the machine may have a battery-powered or plug-in electric motor. The most common self-contained power source for lawn mowers is a small (typically one cylinder) internal combustion engine. ;  Two main styles of blades are used in Multi-function Lawn Mowers. Lawnmowers employing a single blade that rotates about a single vertical axis are known as rotary mowers, while those employing a cutting bar and multiple blade assembly that rotates about a single horizontal axis are known as cylinder or reel mowers (although in some versions, the cutting bar is the only blade, and the rotating assembly consists of flat metal pieces which force the blades of grass against the sharp cutting bar).  There are several types of mowers, each suited to a particular scale and purpose. The smallest types, non-powered push mowers, are suitable for small residential lawns and gardens. Electrical or piston engine-powered push-mowers are used for larger residential lawns (although there is some overlap). Riding mowers, which sometimes resemble small tractors, are larger than push mowers and are suitable for large lawns, although commercial riding lawn mowers (such as zero-turn mowers) can be \"stand-on\" types, and often bear little resemblance to residential lawn tractors, being designed to mow large areas at high speed in the shortest time possible. The largest multi-gang (multi-blade) mowers are mounted on tractors and are designed for large expanses of grass such as golf courses and municipal parks, although they are ill-suited for complex terrain.   What Is a Rotary Tiller and How Is It Used in Gardening? What is a Rotary Tiller?  A rotary tiller, which is also known as a rototiller, power tiller, rotavator, rotary hoe, or rotary plow, is a motorized cultivator. It works the soil by means of rotating tines or blades and is either self-propelled or drawn as an attachment behind either a two-wheel tractor or four-wheel tractor. A rotary tiller is an implement that utilizes its set of curved tines that are attached to a rotating shaft to dig into the soil and turn it into a seedbed that’s ready for planting.  What is a John Deere Rotary Tiller Used For?  A tractor-mounted rotary tiller is a great tool for breaking down soil in an existing garden or turning a piece of land into a new garden space. Small, self-propelled rotary tillers are typically used for domestic gardens. When they are attached to two-wheel or even four-wheel tractors, rotary tillers are utilized on farms. Additionally, rotary tillers have also been used for cleaning the exterior of oilfield pipes and preparing the ground for road construction.  Prepping Your Garden  Rotary tillers are used for primary tillage, as well as secondary tillage, where users break up clods and prepare the soil for planting. Next, they can also be used for cultivation while the crop is growing. If the vegetation is heavy, it is helpful to make a single pass and then wait until after the next rain before tilling again. This process helps to break down your vegetation. Primary tillage requires slow speed, but you may use a higher gear for secondary tillage. It’s important to run your tiller at full engine rpm and then shift gears up or down as necessary.  Cultivating Your Garden  Tillers are effective when it comes to cultivating your crops. The cultivation is usually done at a higher ground speed than what you would use for primary or secondary tillage. Using a very shallow depth setting when cultivating will help you avoid damaging crop roots. ;  Growing and Incorporating Organic Matter  Rotary tillers can help you to incorporate cover crops and green manure crops, which contribute to the health of your garden soil. Additionally, you can improve the structure and tilth of your soil by incorporating vegetation and compost. Planting cover crops is also a possibility. Once the seedbed is prepared, you can then broadcast the seed and run the tiller over the soil at high speed and a minimum depth, which will help to cover the seeds. Tillers are the most effective tool for covering larger seeds, such as peas. Small cover crop seeds – like ryegrass – might be covered too deeply with a tiller. Raking or dragging will be more effective for these smaller seeds.  Middlebusting  Wide sweeps, also known as middle busters, are the most useful accessory for your tiller. A middle buster attaches to the rear of the tiller, allowing you to dig a more shallow furrow. Two passes with a middle buster throw up a raised bed, which can be important in certain areas. Then, you can level the top of that raised bed to plant your crops. ;  Trenching  Tillers also have uses outside of gardens. One example of another use is digging ditches or trenches. Start by running the tiller over the ditch line to loosen the soil. Once this first step is complete, you will want to shovel out the loosened soil and repeat until you reach your desired depth.   Ground Drill An earth auger, earth drill, or ground drill ;is a drilling tool or machine used for making holes in the ground. It typically consists of a rotating vertical metal rod or pipe with one or more blades attached at the lower end, that cut or scrapes the soil.  High-quality hydraulic motors, output shaft bearings that are 50% larger than our nearest competitors\' comparable drive, and the use of only high-grade materials. The latest manufacturing techniques are what make this range of ground drills the market leader. The extensive range of Auger Torque Earth Drills (also known as Auger Drives) gives you complete versatility, peace of mind, and efficiency. Developed to work with all makes and models of parent machines, and complemented with a range of attachments, you will find an earth drill and attachment for your every need. ;님의 프로필 사진

  • http://www.turpanic.com/Integrated Circuits IC An integrated circuit ;(IC), also called a microelectronic circuit, microchip, or chip, is an assembly of electronic components, fabricated as a single unit, in which miniaturized active devices (e.g., transistors and diodes) and passive devices (e.g., capacitors and resistors) and their interconnections are built upon a thin substrate of semiconductor material (typically silicon). The resulting circuit is thus a small monolithic “chip,” which may be as small as a few square centimeters or only a few square millimeters. The individual circuit components are generally microscopic in size.  Integrated Circuits IC has two main advantages over discrete circuits: cost and performance. The cost is low because the chips, with all their components, are printed as a unit by photolithography rather than being constructed one transistor at a time. Furthermore, packaged ICs use much less material than discrete circuits. Performance is high because the IC\'s components switch quickly and consume comparatively little power because of their small size and proximity. The main disadvantage of ICs is the high cost of designing them and fabricating the required photomasks. This high initial cost means ICs are only commercially viable when high production volumes are anticipated.   Microcontroller (MCU) A microcontroller ;is a compact integrated circuit designed to govern a specific operation in an embedded system. A typical microcontroller includes a processor, memory, and input/output (I/O) peripherals on a single chip.  Sometimes referred to as an embedded controller or microcontroller unit (MCU), microcontrollers are found in vehicles, robots, office machines, medical devices, mobile radio transceivers, vending machines, and home appliances, among other devices. They are essentially simple miniature personal computers (PCs) designed to control small features of a larger component, without a complex front-end operating system (OS).   How do microcontrollers work?  A microcontroller is embedded inside of a system to control a singular function in a device. It does this by interpreting data it receives from its I/O peripherals using its central processor. The temporary information that the microcontroller receives is stored in its data memory, where the processor accesses it and uses instructions stored in its program memory to decipher and apply the incoming data. It then uses its I/O peripherals to communicate and enact the appropriate action.  Microcontrollers are used in a wide array of systems and devices. Devices often utilize multiple microcontrollers that work together within the device to handle their respective tasks.  For example, a car might have many microcontrollers that control various individual systems within, such as the anti-lock braking system, traction control, fuel injection, or suspension control. All the microcontrollers communicate with each other to inform the correct actions. Some might communicate with a more complex central computer within the car, and others might only communicate with other microcontrollers. They send and receive data using their I/O peripherals and process that data to perform their designated tasks.   Meba Automatic Voltage Regulators SVC-10KVA Meba Automatic Voltage Regulators SVC-10KVA When the power network voltage fluctuates or the load varies, the automatic sampling control circuit will send a signal to drive the servo motor which can adjust the position of the carbon brush of the auto voltage regulator, then, the output voltage will be adjusted to rated value and get a steady state.   What Is an FPGA? Field Programmable Gate Arrays (FPGAs) are integrated circuits often sold off the shelf. They’re referred to as ‘field programmable’ because they provide customers the ability to reconfigure the hardware to meet specific use case requirements after the manufacturing process. This allows for feature upgrades and bug fixes to be performed in situ, which is especially useful for remote deployments.  FPGAs contain configurable logic blocks (CLBs) and a set of programmable interconnects that allow the designer to connect blocks and configure them to perform everything from simple logic gates to complex functions. Full SoC designs containing multiple processes can be put onto a single FPGA device.   Capacitor A capacitor ;is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals.  The effect of a capacitor is known as capacitance. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit. The capacitor was originally known as a condenser or condensation.   The physical form and construction of practical capacitors vary widely and many types of capacitors are in common use. Most capacitors contain at least two electrical conductors often in the form of metallic plates or surfaces separated by a dielectric medium. A conductor may be a foil, thin film, sintered bead of metal, or an electrolyte. The nonconducting dielectric acts to increase the capacitor\'s charge capacity. Materials commonly used as dielectrics include glass, ceramic, plastic film, paper, mica, air, and oxide layers. Capacitors are widely used as parts of electrical circuits in many common electrical devices. Unlike a resistor, an ideal capacitor does not dissipate energy, although real-life capacitors do dissipate a small amount (see Non-ideal behavior). When an electric potential difference (a voltage) is applied across the terminals of a capacitor, for example when a capacitor is connected across a battery, an electric field develops across the dielectric, causing a net positive charge to collect on one plate and net negative charge to collect on the other plate. No current actually flows through the dielectric. However, there is a flow of charge through the source circuit. If the condition is maintained sufficiently long, the current through the source circuit ceases. If a time-varying voltage is applied across the leads of the capacitor, the source experiences an ongoing current due to the charging and discharging cycles of the capacitor.   What are ceramic capacitors? A ceramic capacitor uses a ceramic material as the dielectric. Ceramics were one of the first materials to be used in the production of capacitors, as it was a known insulator. Many geometries were used in ceramic capacitors, of which some, like ceramic tubular capacitors and barrier layer capacitors, are obsolete today due to their size, parasitic effects, or electrical characteristics. The types of ceramic capacitors most often used in modern electronics are the multi-layer ceramic capacitor, otherwise named ceramic multi-layer chip capacitor (MLCC), and the ceramic disc capacitor. MLCCs are the most produced capacitors with a quantity of approximately 1000 billion devices per year. They are made in SMD (surface-mounted) technology and are widely used due to their small size. Ceramic capacitors are usually made with very small capacitance values, typically between 1nF and 1μF, although values up to 100μF are possible. Ceramic capacitors are also very small in size and have a low maximum rated voltage. They are not polarized, which means that they may be safely connected to an AC source. Ceramic capacitors have a great frequency response due to low parasitic effects such as resistance or inductance.   Characteristics  Precision and tolerances  There are two classes of ceramic capacitors available today: class 1 and class 2. Class 1 ceramic capacitors are used where high stability and low losses are required. They are very accurate and the capacitance value is stable in regard to the applied voltage, temperature, and frequency. The NP0 series of capacitors has a capacitance thermal stability of ; ±0.54% within the total temperature range of -55 to +125 °C. Tolerances of the nominal capacitance value can be as low as 1%.  Class 2 capacitors have a high capacitance per volume and are used for less sensitive applications. Their thermal stability is typically ±15% in the operating temperature range, and the nominal value tolerances are around 20%.   Size advantages  When high component packing densities are required, as is the case in most modern printed circuit boards (PCBs), MLCC devices offer a great advantage compared to other capacitors. To illustrate this point, the “0402 multi-layer ceramic capacitor package measures just 0.4 mm x 0.2 mm. In such a package, there are 500 or more ceramic and metal layers. The minimum ceramic thickness as of 2010 is on the order of 0.5 microns.   High voltage and high power  Physically larger ceramic capacitors can be made to withstand much higher voltages and these are called power ceramic capacitors. These are physically much larger than those used on PCBs and have specialized terminals for safe connection to a high voltage supply. Power ceramic capacitors can be made to withstand voltages in the range of 2kV up to 100 kV, with a power specified at much higher than 200 volt-amperes.님의 프로필 사진

Laminated Bags: The Strongest Bag Material Laminated bags ;are super strong and allow full-color processing. Know the details to make the most of this reusable bag fabric.  How Are Laminated Bags Made?  Laminated bags begin with a base layer (substrate) that is white. Then, a thin layer of polypropylene sheeting is printed with four color graphics and laminated on top of the substrate. The top layer is heat bonded for a permanent seal. Panels are precision cut and sewn after printing.   Substrates  Most laminated bags use one of the following three substrates. No matter which one you choose, the four-color graphics in the exterior lamination layer is all the customer will see from the outside. The substrate is only visible on the inside of the bag.  Woven PP For this material, strips of PP are woven together and a lamination layer bonds the weave together. This material is incredibly strong for its weight and is often used for sandbags, tarps, and other industrial uses. This material puckers after 6-8 months as the material ages.  NWPP Lamination gives NWPP a strong, puncture-resistant top layer for a smooth great looking bag. Once laminated, NWPP weighs 120 GSM, making it extra durable and long-lasting. This is a premium choice for grocery bags, promotional bags, or custom bags for any organization.  Recycled PET (rPET) Water bottles are shredded and spun into a substrate fabric to create recycled reusable bags. The lamination sheeting is not recycled, so the final bag contains 85% post-consumer waste. RPET bags are the gold standard in eco-friendly bags, ideal to demonstrate your commitment to the environment.

  • http://www.wanjie-tb.com/A terminal block (also called as connection terminal or terminal connector) is a modular block with an insulated frame that secures two or more wires together. It consists of a clamping component and a conducting strip. Due to the terminal connection, the joint of the wire can be kept proper and secure. And the wire can also be properly aligned. Terminal blocks can be classified on the basis of their structure, device type, termination options.  PCB screw terminal blocks are modular, insulated devices that mount on printed circuit boards (PCBs) and secure two or more wires together. PCB terminal block connector also known as electronic blocks, are manufactured to be mounted on a printed circuit board, or PCB. Terminal blocks are used to secure and/or terminate wires and, in their simplest form, consist of several individual terminals arranged in a long strip.  Screwless terminal blocks have spring terminals that automatically grip inserted wires and release when their levers are pressed, enabling easy, temporary connections to a PCB. Various sizes are available in two orientations (side-entry and top-entry) and two pin spacings (0.1″ and 0.2″). These terminal blocks can be combined to make longer ones, or segments can be removed to make them shorter. Each block has two pins per terminal, and they are intended for use with PCBs that have the appropriate footprints.  MCS terminal block uses high-elastic and high-quality spring clips for single-strand and multi-strand connections. The characteristic is safe, fast, and reliable and it is suitable for wire-to-wire, board-to-wire and board-to-board connections to achieve power and signal transmission.  Feed-through terminal blocks are characterized by two terminal points and a compact design. Ground terminals of the same shape are available to match the feed-through terminal blocks. All bridgeable terminal blocks can be bridged together easily with multi-conductor and function terminals. A feed-through terminal block is suitable for joining and/or connecting one or more conductors. They could have one or more connection levels that are on the same potential or insulated against one another.  The barrier terminal block is designed for power applications and integrates a transparent clamshell safety cover. Barriers can tolerate cluttered or worn wire ends to prevent electrical shorts between positions on the same terminal block and adjacent components. There are a variety of high-quality barrier-style terminal blocks in single-row, double-row, and high voltage options to fit a variety of applications. The barrier terminal blocks (sometimes called barrier terminals or barrier strips) are built with sturdy, thermoplastic materials to make them break-resistant and heat-resistant.  DIN rail terminal blocks are used to protect electrical systems against overcurrent and short-circuiting. They clip onto a DIN rail, which is a standard-size metal rail on which terminals are mounted in a control cabinet. DIN rail terminals are made from plastic, as this insulates the electrical current running through the terminal. Fused DIN rail terminals often have a hinged section containing the fuse, which can be opened up to stop the flow of electricity. Some are fitted with an LED blown fuse indicator to let you know when the fuse needs changing. Fused DIN rail terminals come with different fuse size inserts and may be color-coded to indicate the current rating. Non-fused work the same, just without the fuse protection.  A circular connector is a cylindrical, multi-pin electrical connector that contains contacts that power electrical devices, transmit data, or transmit electrical signals. A circular connector is designed to withstand harsh environments and reliably deliver data. It is designed with a circular interface and housing to quickly and easily connect and disconnect signal, power, and optical circuits without the use of coupling tools such as torque wrenches. The contacts are typically surrounded by a composite or metal shell and are embedded in insulating material to maintain their alignment. The contacts are usually paired with a cable, making them especially resistant to accidental decoupling or environmental interference.  A breadboard is used to build and test circuits quickly before finalizing any circuit design. The breadboard has many holes into which circuit components like ICs and resistors can be inserted. The holes are most commonly spaced 0.1“ apart to accommodate standard DIP components. The breadboard has strips of metal sockets that run underneath the board and connect the groups of five holes on the board.  A jumper wire (also known as jumper, jump wire, DuPont wire) is an electrical wire, or group of them in a cable, with a connector or pin at each end (or sometimes without them – simply \"tinned\"), which is normally used to interconnect the components of a breadboard or other prototype or test circuit, internally or with other equipment or components, without soldering. Individual jump wires are fitted by inserting their \"end connectors\" into the slots provided in a breadboard, the header connector of a circuit board, or a piece of test equipment.님의 프로필 사진

  • http://www.jinlanwindowfilm.com/Window film (tint) is a thin laminate film that can be installed to the interior or exterior of glass surfaces in automobiles and boats and also to the interior or exterior of glass in homes and buildings. It is usually made from polyethylene terephthalate (PET), a thermoplastic polymer resin of the polyester family, due to its clarity, tensile strength, dimensional stability, and ability to accept a variety of surface-applied or embedded treatments. Window films are generically categorized by their construction components (dyed, pigmented, metalized, ceramic, or nano), their intended use (automotive, marine, or architectural), substrate type (glass or polycarbonate), and/or their technical performance (privacy, solar control, safety, and security).  Automotive window film is used to protect the vehicles. The film can block a lot of heat generated by infrared rays very well and prevent skin damage, but also reduce car interior aging. The base layer of the film is a polyester film, which is very resistant to tearing and breakdown. With the adhesive layer of the film, the strength of the glass after the film is applied can prevent the accidental glass breakage from causing damage to the driver and passengers. After the film is applied, it is usually impossible to see the inside of the car from the outside of the car, while the outside of the car can be seen clearly from the inside of the car, preserving privacy and security.  Architectural window film is a self-adhesive or static cling that can be used for a variety of permanent or temporary applications. Glass film is extremely adaptable as it can be cut into precise designs, such as letters and numbers, or printed to create eye-catching visuals such as pictures or company branding.  Paint protection film (PPF, also called a clear bra, clear film, or clear paint film) is a thermoplastic urethane often self-healing film applied to painted surfaces of a new or used car in order to protect the paint from stone chips, bug splatters, and minor abrasions. This film is also used on airplanes, RVs, cell phones, electronics, screens, motorcycles, and many other areas. The paint protection film is OEM approved by virtually all car manufacturers. The paint protection film is installed on a limited basis by manufacturers on various pieces of cars at the factory (e.g. the rear arches of Porsches). This film is most commonly applied to high-impact areas of vehicles which include: the hood, the front fenders, the front bumper, the side-view mirrors, the rocker panels, the lower portion of the doors, and the rear guards behind the rear wheels.  TPU PPF is a high-performance, uncoated thermoplastic polyurethane (TPU) paint and surface protection film. It provides a strong and durable shield for any bare or painted metal, glass or plastic surface exposed to extreme conditions to prevent damage from abrasion, chipping, chemicals and wear. TPU PPF has excellent abrasion and impact resistance to provide adhesive coaters, automotive engineers, appliance designers and electronics display manufacturers a durable layer of protection for cars, trucks, appliances, mobile devices, computers, electronic display screens and more. TPU paint and surface protection films offer coaters and converters consistent optical clarity, conformability, UV resistance, lay-flat and Class-A gloss finish required for their products.  TPH PPF comes in either optically clear high-gloss or matte finishes, so it disappears into automotive paint and can be used to create special effects. Our superior film is applied to the surface of the vehicle to create a barrier against water, insects, road debris, and other stains. With either finish, there are benefits of self-healing film and our proprietary technology. When exposed to heat, the enhanced clear coat properties eliminate fine scratches and swirl marks over time. Road grime, bird droppings, bug guts, and air pollution will never leave the film stained or yellow, unlike lower quality alternatives.  Car wrap film is a film designed for the car to protect the surface. It has a variety of advantages. It can reduce air conditioning load and save fuel. The loss of cooling capacity of the air conditioner can be compensated by putting on the heat insulation film, which can instantly reduce the temperature in the car and save fuel consumption to a certain extent. In addition, it can increase beauty. According to personal preferences, the car can be personalized and beautiful through the film.  A matte vinyl car wrap film is unique in that the matte vinyl finish absorbs more light than a gloss finish wrap does, which means that the printed colors in a matte vinyl vehicle wrap can look both rich and subdued at the same time. It also can provide a strong and durable shield for any bare or painted metal, glass, or plastic surface exposed to extreme conditions to prevent damage from abrasion, chipping, chemicals, and wear.  Glossy vinyl car wrap film mimics the paint finish we usually find with vehicles. This vinyl film makes the car glitters and reflects light. The glossy wrap film is high quality that molds perfectly well with heat to any curves and contours.님의 프로필 사진

  • http://www.airhank.net/7.5kw belt-free turbine blower is a non-positive displacement, high volume, high pressure, blower that can operate as either a compressor or a vaccum pump. It is also knows as other names such as regenerative blower, vortex blower and side channel blower. All of the names describe the basic principle of operation of the turbine blower. The blower consist of a strong impeller mounted directly on a motor shaft and is rotated at very high speed of about 2900 R.P.M. On the periphery of the impeller is large number of radial blades. The impeller is positioned between two end plates and with the blades located with a channel on either side.  High speed centrifugal blower, as the name suggests, high speed, fast. It is also called high speed turbo blower. Under the design conditions, the air pressure of the high speed centrifugal blower reaches 50-290 mbar, the air volume is 85-6000 cubic meters per hour, the rotating speed is 18000-21000 rpm, and the air volume is three times that of the ordinary high-pressure blower. Therefore, it is also named high-speed blower, and the use effect is more than 95%. High speed centrifugal blower is also called: High-speed fan, High-speed blower, turbine type high-speed blower, super fan, high-speed centrifugal fan, etc., but it is generally called high-speed centrifugal fan in foreign countries, because the fan uses the centrifugal principle to generate rotating mechanical energy and convert it into aerodynamic force with a certain pressure. The English name is mostly centrifugal blower.  Side channel blowers are of use to any process that requires a high volume low pressure delivery system for air or gasses. Here is a list of common use cases including air knives, dry tunnel blowing, process cooling, air cushions, packaging processes, vacuum cutting tables, vacuum cleaners, vacuum cleaning systems, industrial fume/heat extraction, aeration, blowers for swimming pools.  Air knives, including strip air knives and ring air knives, are a kind of equipment specially designed to blow out strong and high-speed airflow to remove dust, blow water stains, and cool down. There is also an air knife for cutting boards. The air knife consists of high-intensity, uniform laminar airflow.  Stainless steel adjustable air knives have the greatest advantage which is that going through an adjustable outlet the airflow can be more stable and stronger. Stainless steel air knives are featured by high precision, strong hardness, high pressure-resistance, and great temperature-resistance. The air knives are widely used in all kinds of blowing off system and air knives drying system. They are also widely applied for ultrasonic cleaning, glass cleaning machines, and dehydration and drying of a circuit board, electroplate, film, coating, non-ferrous metal board/wire/sheet, and other related materials and industries. Moreover, they are also utilized in the barrierless isolation of harmful gases, dust, hot and cold air, drying after printing, heating, and thawing of food and medicine, and high-temperature sterilization.  The greatest advantage of spider nozzle air knives is that they can flex to any position around the bottle to accommodate specific drying needs. Spider air knife has been through many tests and trials. Its innovative design, not only improves the drying efficiency of the bottling and canning production line, but also reduces energy usage by as much as 80% compared with traditional air knives. Moreover, spider air knives also solve the following problems that occurred on the traditional bottling and canning production lines–two air knives usually head to head blow air, which offsets the airflow and even makes a “drying blind” zone.  A belt-free centrifugal blower is an air moving device that uses an impeller to pull air into a tube like structure and release it at a 90o angle. The impeller is a set of blades inside the blower that rotates at a high rate to pressurize and move air. The structure of a centrifugal blower does not require housing for protection, but those with housing are the most common.  The double-stage single phase side channel blower are conceived to suck or to compress gas and non-explosive mixtures. The absence of lubricants guarantees that no oils are present in the compressed fluids. The blowers are equipped with single-phase motors and IE3 high efficiency three-phase motors. The main advantages of double-stage blowers are no maintenance, no contamination of conveyed fluids, silent operation, small size and weight, easy of installation, stability and absence of vibrations. The blowers are mainly applied in fields including air and gas conveyance on machines and plants requiring high suction and delivery pressures, max. operational safety and low noise levels.  Bare shaft side channel blowers are very widely used, that is, the airflow in the same direction as the axis of the fan blades, such as electric fans, air conditioner outdoor fans are axial flow fans. The blowers are usually used in applications with high flow requirements and low pressure requirements. The blower fixes the position and move the air. The bare shaft side channel blowers are mainly composed of the fan impeller and the casing. The structure is simple but the data requirements are very high.  There are many blower accessories including press relief valve oil sight gauge, blower lube, bearings and seals, blower bolt kit and alum blower studs.님의 프로필 사진

  • http://www.hoututea.com/Green tea is made from the Camellia sinensis plant. Its dried leaves and leaf buds are used to make several teas, including black and oolong teas. Green tea is prepared by steaming and pan-frying the Camellia sinensis leaves and then drying them. Green tea is not fermented, so it\'s able to maintain necessary molecules called polyphenols, which seem to be responsible for many of its benefits. It also contains caffeine. Drinking green tea is linked to a reduced risk of clogged arteries. Drinking green tea might reduce the risk of developing high blood pressure. It might also slightly lower blood pressure in people with high blood pressure.  One of the most classical Chinese green teas, Chunmee tea is a tea every tea lover has to try at least once. It offers a good perspective on a wide range of green tea flavors, may offer numerous benefits, and tastes great, both hot and cold. It’s produced only in China, mostly in Anhui and Jiangxi Province. The English name of this tea is \"Precious Eyebrows tea\" because of the small hand-rolled leaves shaped in the form that resembles eyebrows. Chunmee is produced in China and is one of the most popular green teas in western countries. Chunmee is a pan-fired tea. Pan-fired teas have a less vegetal and nuttier flavor, that can be light or more intense, depending on how the teas were made.  Gunpowder tea is loose-leaf tea that is tightly rolled into tiny pellets that resemble gunpowder. This type of tea is usually produced using green tea leaves, but not always. The benefits of gunpowder tea depend on the type of tea leaf that is used to produce it. Gunpowder tea has a unique production method. To make the highest quality gunpowder tea, artisans wither, steam, roll, and dry individual tea leaves. This tea is sometimes called pearl tea or bead tea based on the shape of each tiny tea pellet. Some people also call it Chinese gunpowder tea.  A tea bag (or \"teabag\") is generally agreed to be a small, porous bag used to steep tea. These bags may be sealed and filled with tea leaves, or they may be open and empty (thus allowing the tea brewer/drinker to fill it with whole-leaf tea). Many tea bags have a string attached to make removing them from the brewing vessel easier, however, this is not true for all tea bags. Generally, tea bags with a string attached also bear the name of their producer or the type of tea on a small piece of paper at the opposite end of the string from the tea bag itself.  The famous tea in the 21st century includes Xi Hu Long Jing, Jiangsu Bi Luo Chun, Huang Shan Mao Feng, Liu An Gua Pian, Fujian Bai Hao Yin Zhen, Qimen Hong Cha, Du Yu Mao Jian, Xin Yang Mao Jian, Wuyi Yan Cha, Fujian Tie Guan Yin. Most of them have a singular shape, flavor, and aroma, easily discerned from other styles, and are developed from a particular local variety of tea bush that has acquired strong and widespread appeal.  Flower tea is a mixture of tea and tisanes. In ancient times, people used tea as a herbal medicine long before drinking it for pleasure. They added flowers to boost the medicinal value and sensory delights of the tea. Some blossoms commonly used in flowering tea are jasmine, calendula, globe amaranth, marigold, and lily.님의 프로필 사진

  • http://www.adencn.com/Energy recovery ventilation (ERV) is the energy recovery process in residential and commercial HVAC systems that exchanges the energy contained in normally exhausted air of a building or conditioned space, using it to treat (precondition) the incoming outdoor ventilation air. The specific equipment involved may be called an Energy Recovery Ventilator, also abbreviated ERV.  Ductless ERVs provides fresh air, recovers the heat to save energy, and doesn\'t need ducts running to each and every room in the house.  Commercial Energy Recovery Ventilators (ERVs) are the best choice for ventilating your home or workplace. These units are designed to provide fresh air into the building while exhausting an equal amount of stale air to the outside.  Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in the beat-to-beat interval.  An air curtain is a fan-powered device that creates an invisible air barrier over the doorway to separate efficiently two different environments, without limiting the access of the people or vehicles.  Centrifugal Air Curtains are highly acclaimed for their tough construction and low maintenance, showing fire prevention performance. These air curtains are specifically designed to maintain the temperature, hygiene and humidity during traffic movement through the doors.  A fan filter unit (FFU) is a type of motorized air filtering equipment. It is used to supply purified air to cleanrooms, laboratories, medical facilities or microenvironments by removing harmful airborne particles from recirculating air.[1] The units are installed within the system\'s ceiling or floor grid. Large cleanrooms require a proportionally large number of FFUs, which in some cases may range from several hundred to several thousand. Units often contain their own pre-filter, HEPA filter and internally controllable fan air distribution.  As the name implies, ventilation fans are used to ventilate a residential or commercial space. This works to bring fresh air from the outside and into the enclosed space. It helps circulate air through the building or home, which prevents individuals from breathing stuffy, less oxygenated air. Without ventilation, you and other individuals will be left breathing air that is not fresh.  At its simplest, a duct fan (also known as an inline duct fan or simply an inline fan) is a fan that is installed inside of a ventilation duct, rather than at the end point of a duct or through a wall. However, there are many variations of duct fans, and these should be understood before deciding whether or not this is a good way to meet your ventilation needs.  Rectangular duct fan are intended for ventilation of medium size and large rooms where space is limited. The DV-SQ duct fans have been designed and manufactured in order to ensure the high efficiency, failure-free operation and direct connection to the ventilation duct.님의 프로필 사진

  • http://www.sxpdtextile.com/We all know that there are lots of fabric used in our daily clothes or furniture, etc. And a new kind of fabric nowadays are more and more popular. That is Double Brush Fabric.   What is Double Brushed Poly Fabric?  Double brushed polyester knit is a fashion apparel fabric that has 4 way stretch made from polyester and spandex blend. This fabric has undergone treatment which brushes the surface of the fabric giving it the look of suede and is commonly available in single or double brushed. It is soft to touch (some would refer to it as being buttery or soft like a peach) and made famous by LuLaRoe as it is the base fabric for most of their garments.   Fabric has fantastic colour fastness and washes well time and time agai however, being polyester it isn\'t environmentally friendly. Fabric has a floaty drape and doesn\'t require ironing, it can be used as a base fabric for most apparel patterns that asks for stretch knits. There\'s an array of solid colours and prints available in the marketplace, in Australia we are slowly \"warming\" up to the idea of double brushed polyester and as it gets popular you may start seeing a variety of solids and prints being stocked at your local fabric shop.   Another well used fabric is scuba fabric.   What is scuba fabric?  Scuba fabric is a type of double knit made from polyester and spandex, with a very fine gauge thread, and smooth texture. It\'s a little springy, very smooth and has a nice drape to it. Scuba fabric should not be confused with neoprene which is a thicker synthetic rubber and fabric hybrid that is more durable, flexible and is often used for wetsuits. You can also buy a fabric called scuba crepe which is a lighter version of scuba, more like a traditional Lycra but with a crepe textured finish. It can be divided into many types like Scuba Knitting Fabric, Scuba Crepe Fabric, etc.   After the war, it was discovered that Neoprene had a variety of uses beyond military equipment. For instance, manufacturers started making wetsuits with this material, and Neoprene became incredibly popular among surfers and scuba divers.   One of the issues with scuba diving at the time was the fact that most other fabrics to make scuba suits were water permeable. Neoprene, however, makes a total water barrier between the skin and the environment surrounding it, which makes it ideally suited for scuba diving gear. While neoprene might be a dream come true for scuba divers, this waterproof feature detracts from its performance in the wider world of apparel. Neoprene isn\'t breathable at all; any sweat you exude while you\'re wearing this scuba diving material will stay between your skin and the material until you take the piece of Neoprene clothing off.   This factor makes it so that Neoprene is only truly suited for loose-fitting clothing or clothing that doesn\'t cover a large portion of the body. While its stretchiness would make it an ideal material for tight-fitting sportswear, its lack of breathability detracts from this benefit significantly.   Except these, many other kinds of fabric are used for different usages, such as Jacquard Fabric, Roma Fabric, Bullet Fabric, Woven Fabric, SPH Fabric, etc.님의 프로필 사진
