How to choose the fabric of anti-static clothing in the purification workshop? Anti-static clothing has dustproof and anti-static properties, and is widely used in special enterprises such as electronics factories, pharmaceutical factories, and chemical plants. Whether the performance of an anti-static clothing is mainly depends on the fabric of the anti-static clothing. When it comes to anti-static fabrics, many people are not familiar with it. Anti-static fabrics can also be called anti-static fabrics. Anti-static fabrics are different from ordinary ones. The fabric, which is woven from wire and blended. So what is special about antistatic fabrics? How does anti-static fabric play an anti-static effect? Xiaobian here made a detailed anti-static fabric classification, share it with everyone:
1. It adopts special polyester filament, warp and weft-embedded conductive fiber, which is processed by special process. It not only has excellent anti-static function, but also effectively prevents the fabric fiber from falling off, and the fine dust particles seeping from the gap of the fabric. It has the characteristics of being free from environmental influences (high temperature resistance) and stable chemical properties (washing resistance). The product specification is 68D×75D, which is suitable for the clean room of level 10 to 100. It is widely used in microelectronics, optoelectronics, precision instruments, aerospace and other industries that are sensitive to static electricity and have high requirements for cleanliness.
2, conductive silk, polyester as the main body, special polyester filament and high-performance permanent conductive fiber woven by special process, warp weaving or warp and weft inlaid conductive fiber. The garment made of this anti-static fabric through special sewing process has excellent anti-static and dustproof performance, high-efficiency, permanent anti-static, dust-proof performance and soft, thin and smooth, and the texture is clear, mainly used for making Dust-proof clothing and anti-static overalls are customized to achieve corona discharge or leakage discharge. Different specifications of anti-static fabrics are suitable for different anti-static or clean environments. Applications: medical, pharmaceutical, food, precision instruments, aerospace, etc. Statics are more sensitive and require a higher level of cleanliness.
3, anti-static cotton fabric: in the middle of the cotton fabric woven into the conductive fiber (pitch 1.2CM) through the special process of finishing, to achieve anti-static fabric.
4. In the polyester fiber short-staple fine-spun yarn fabric, the conductive fibers (pitch 1.2cm) are woven at medium pitch. The fabric is denser than ordinary fabrics with special anti-static and anti-burning functions. This kind of fabric is strong, wear-resistant, soft and comfortable, moisture-absorbing and breathable. It can be processed into various high-grade anti-static cotton overalls. It is suitable for storage and transportation, chemical, gas, petroleum, coal, sea, aerospace, military and other inflammable and explosive working environment. .
5. It is made by knitting a series of conductive fibers and special polyester filaments. Anti-static knit fabric not only eliminates static electricity but also does not dust. It also has the characteristics of ordinary knit fabric which is breathable, warm and comfortable. It is a new generation of anti-static fabric that meets human health requirements.
Directional control valves (DCVs) are one of the most fundamental parts of hydraulic and pneumatic systems. DCVs allow fluid flow (hydraulic oil, water or air) into different paths from one or more sources. DCVs will usually consist of a spool inside a cylinder which is mechanically or electrically actuated. The position of the spool restricts or permits flow, thus it controls the fluid flow.
The spool (sliding type) consists of lands and grooves. The lands block oil flow through the valve body. The grooves allow oil or gas to flow around the spool and through the valve body. There are two fundamental positions of directional control valve namely normal position where valve returns on removal of actuating force and other is working position which is position of a valve when actuating force is applied. There is another class of valves with 3 or more positions that can be spring centered with 2 working position and a normal position.
