Anti-static clothing testing equipment industry application
Core Tips: 1. Anti-static overalls are special work clothes with dust-free and anti-static properties suitable for electronics, optical instruments, pharmaceuticals, microbiology engineering, precision instruments, etc.
1. Anti-static overalls are special work clothes with dust-free and anti-static properties suitable for electronics, optical instruments, pharmaceuticals, microbiology engineering, precision instruments and other industries. The clothing materials are generally synthetic fiber fabrics with embedded conductive filaments. "Anti-static overalls" (GB12014-1989) is used to prevent static electricity from accumulating clothes and is sewn with anti-static fabrics. It is suitable for use in places sensitive to static electricity or fire or explosion hazards. The antistatic fabric used is mainly made of antistatic fibers or antistatic synthetic fibers made of conductive materials of all or part of metal or organic materials at substantially equal intervals or evenly during weaving, or a mixture of the two. . The anti-static overalls series produced by Dongguan Jiachuang are all made of high-quality fabrics, with good anti-static shielding performance and no dust, suitable for customers with various requirements. Work clothes are available in split, split, and hood styles. Socks, hats, and masks can be combined freely, and can be sampled and processed according to customer requirements. Anti-static overalls are suitable for: petroleum industry; mining and metallurgy industry; chemical industry; electronics industry; special industry, such as: atomic energy, aerospace, weapons, etc. Other industries, such as: food, fireworks, medicine, etc.
Anti-static overalls refer 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. At present, most of the anti-static fabrics are made of conductive fibers, especially the conductive component composite type, that is, the composite fiber is used most.
The anti-static overalls made of conductive fibers are 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.
Second, anti-static clothing in the anti-static ultra-clean fabric characteristics Anti-static overalls used in anti-static overall clothing is often referred to as "conductive silk." In fact, this statement is not strict. Conductive silk can be divided into anti-static (ESD) and clean room according to its own technical characteristics. Only conductive silk suitable for clean room can be called It is an anti-static and ultra-clean fabric.
