Knowledge delivery: Anti-static fabrics and application scope
The weather in winter is unusually dry, and many of my friends encounter hair and clothing that cause static electricity. So anti-static fabrics dress up. Here are some anti-static fabrics and their application. Conductive silk Using polyester as the main body, special polyester filaments and high-performance permanent conductive fibers are woven by special processes, and the direction-inlaid or warp and weft-inlaid conductive fibers are used. The garment made of this kind of fabric by special sewing process has excellent anti-static and dustproof properties, and has the characteristics of high efficiency, permanent anti-static, dust-proof performance, and soft, thin, smooth texture, and is mainly used for making dust Clothing, anti-static clothing, to achieve the effect of corona discharge or leakage discharge, different specifications of the fabric to adapt to different anti-static or clean environment. Scope of application: Apply medical, pharmaceutical, food, precision instruments, aerospace and other industries that are relatively sensitive to static electricity and require a high degree of cleanliness. Anti-static and ultra-clean fabric The use of special polyester filaments, warp-wise weft-inserted conductive fibers, and special processing to make them not only have excellent antistatic function, but also can effectively prevent the fabric fibers from falling off and the fine dust particles from oozing out of the fabric gaps. And has no environmental impact (high temperature), stable chemical properties (wash-resistant) and other characteristics. Product specifications for the 68D × 75D grid, apply to the clean room from class 10 to 100 widely used microelectronics, optoelectronics, precision instruments, aerospace and other static sensitive and cleanliness requirements of the industry. Scope of application: Class 10 to Class 100 clean rooms are widely used in microelectronics, optoelectronics, precision instruments, aerospace and other industries that are sensitive to static electricity and require a high degree of cleanliness. Anti-static knitted fabric The series of conductive fibers and special polyester filaments are knitted and processed. Anti-static knitted fabrics can not only eliminate static electricity but not produce dust. They also have the characteristics of breathable, warm, and comfortable feel of ordinary knitted fabrics. It is a new generation of anti-static fabrics that meet human health requirements. Scope of application: Commonly used in processing anti-static gloves, anti-static underwear. Anti-static dustproof fabric The polyester staple fiber fine-count yarn fabric is woven with conductive fibers (1.2cm pitch) at a medium pitch, and is finished by a special process. Its fabric density is larger than ordinary fabrics, and it has the functions of antistatic and anti-combustible. This kind of fabric is hardwearing, soft and comfortable, moisture-absorbing and breathable, and can be processed into various high-grade anti-static cotton work clothes. Scope of application: Storage, chemical, gas, petroleum, coal, shipping, aerospace, military and other flammable and explosive operating environment. Other anti-static fabrics Anti-static gaodai : In the middle of the gabardine fabric weave conductive fibers (spacing 1.2CM) through a special finishing process to achieve anti-static fabrics. Anti-static cotton : In the middle of cotton fabric weaving conductive fiber (1.2CM pitch) is processed by special process to achieve the anti-static function of the fabric. 3000 Lbs electric winch are 12 v and 24 v DC winches.
It can be used for marine railway, atv or boat applications.
If you need to get something unstuck, lifted, or loaded, an electric winch can save a ton of back-breaking work.
The hardest part may be deciding which one you need.
Winches are commonly available with either a 12V DC or a 110V AC motor.
For fixed operations, such as a marine railway, a 110V winch works well because it can be plugged into an electrical outlet.
For portable applications or use with a vehicle as the anchor, a 12v Winch is the way to go. These units can be hard-wired into a vehicle or simply hooked up to a battery.
The next consideration is capacity-what weight rating should you look for? As a general rule, take the maximum load that you expect to winch and multiply it by 1.5. The weight rating is based on the first wrap of the cable around the drum. With each layer of cable, the pull capacity actually drops, so when in doubt, go larger.
Always stay well to the side of a working winch, and always drape a heavy jacket or tarp over the line. If a cable breaks, the heavy material will help absorb the energy of the taut cable as it snaps back, and reduce the chance of injury.
If a load outweighs your winch rating, remember those high school physics lessons about pulleys and mechanical advantage. You can double the pulling capacity by [doubling" the line. Run it through a Snatch Block attached to the object you`re moving and then back to a fixed object. Twice the capacity, however, equals half the pulling speed.
