Analysis of the main performance of anti-static dust-free clothes
Nowadays, many enterprises will use anti-static and dust-free clothes. So what kind of effect can anti-static clean clothes bring? Today, together with Rong Xin Xiao Lu to understand the role of anti-static clean clothes and analyze its performance.
In general, the main difference between the anti-static and dust-free clothes is that there are two major points: 1. Reduce the fire caused by static electricity, 2. Avoid the adsorption of dust inside the workshop, 3. Dust-free clothing, prevent dust on the body. Fine particles such as dust, dander or hair are scattered into the clean room. Generally speaking, it is common in microelectronics and biological laboratories. In general, the clean clothes are mainly to avoid the pollution of the internal clean room caused by the dust from the outside, so the advantage of the clean clothes is also conspicuous.
Anti-static dust-free clothing
Anti-static clean clothing refers to work clothes that are sewn with anti-static fabric as a fabric to prevent static build-up on clothing. The antistatic fabric is a fabric obtained by mixing conductive fibers or antistatic synthetic fibers or a mixture of the two at substantially equal intervals or evenly during weaving. The conductive fiber is a general term for fibers made of a conductive material or a subconductive material using metal or organic materials in whole or in part, and has a volume resistivity ρv ~ between 104 and 109 Ω/cm. According to the distribution of the conductive component in the fiber, the conductive fiber can be classified into three types: a conductive component uniform type, a conductive component covering type, and a conductive component composite type. An antistatic and dust-free garment made of conductive fibers is added to the chemical fiber fabric, and the power-dissipation is based on two mechanisms of charge leakage and neutralization. When grounded, the static electricity on the fabric is neutralized by the corona discharge of the conductive fibers, and can also be discharged to the ground via the conductive fibers; when not grounded, the electricity is dissipated by the weak corona discharge of the conductive fibers. Therefore, anti-static dust-free clothing is very extensive, anti-static dust-free clothing is suitable for the petroleum industry; mining and metallurgy industry; chemical industry; electronics industry; special industry, such as: atomic energy, aerospace, weapons and so on. Other industries, such as: food, fireworks, medicine, etc.
Because anti-static clean clothing is often used in industries with high cleanliness requirements, such as bioengineering, medicine, semiconductors, etc., these companies have high requirements on the amount of dust generated in the production environment, the lower the better. Because the anti-static dust-free clothes have strong effects and excellent effects, the maintenance of anti-static dust-free clothes is very important. The cleanliness in the clean room is 10,000 times higher than that in the hospital operating room. Achieving and maintaining this level of cleanliness requires a lot of advanced technology. It is necessary to use a large air filtration system to convert the air in the clean room 10 times per minute, greatly reducing the probability of particles in the air contaminating the chip.
