First, antistatic fabric
Many varieties of anti-static fabric, summed up in roughly three types:
The first clothing fabric antistatic agent is optional resin finishing, impregnation, curing and synthetic fabric adhesion surface, the fabric has some antistatic effect. This method is now used only for civilian clothes, clothes overcome ridden, spark discharge, electrostatic dust pollution absorption phenomena.
The second is added internally, such as phosphate, sulfonate surfactants, or the third monomer polyester or nylon polymer antistatic agent to obtain durable antistatic fibers. Since most of the additive based on the circumstances can react or decompose the surfactant, so the fabric finishing or alkaline detergent to avoid affecting the antistatic effect hanged antistatic agent, suitable clean clothes, sterile clothes fibers can also be used in civilian clothes.
Third, in general mixed conductive fiber fabrics, such as anti-static fabrics from the environment, which is now widely accepted and recognized. This anti-static fabric antistatic properties of conductive fiber and conductive component types (metal, graphite, carbon black, etc.) in the fiber segments and is divided into a homogeneous conductive component, a conductive component of the cover, the conductive compound component and a conductive component mixing four. Which contains carbon black, graphite, and other conductive components of the conductive fiber composite yarn can be used directly in a certain distance (for example, about 1.5 cm) embedded in the conductive yarn weaving, warp, you can get a good anti-static effect, currently used anti-static fabric weaving best conductive fibers.
Second, the product categories
Can be divided into A and B grade clothes, according to the time difference antistatic property. One, A-level resistance to washing time should be 33.0 hours, B-class resistance to washing time should be 16.0ħ.
Third, anti-static overalls, the main technical performance
Anti-static overalls, must be in accordance with national standards, national mandatory standards GB12014-1989 "anti-static overalls." Antistatic overalls main technical requirements are anti-static properties that each anti-static clothing charge, this requirement is directly related to the protection of the product performance. In addition, the fracture strength of joints, hardware accessories, kimono lining the fracture strength of clothes to wear and anti-static effect of technical indicators.
Fourth, how to buy anti-static overalls
Figure 1 shows, the structure requires
(1) easy to wear, comfortable, easy to escape, is beneficial to human activity.
(2) Do not use metal garment accessories in general, must be used (buttons, zippers, etc.), you should ensure that when worn, not direct contact with metal accessories.
(3) All clothing should use an anti-static cloth, do not use lining. You must use the lining (pockets, reinforced cloth, etc.), the exposed area of the lining of the total anti-static overalls inner surface area exposed to 20% or less, more than 20% (such as winter clothing or special clothing) should mask and removable lining.
2, the style requirements
"Three tight", Bottoms normal dress coat is straight or "three tight" jumpsuit.
Fifth, use and precautions
1, under normal circumstances, an explosive gas mixture continuous, frequent or long or short rest and the presence of explosive gas mixtures is possible to place combustibles minimum ignition energy of 0.25 mJ or less, should wear anti-static clothing .
2, in explosive areas prohibit anti-static overalls to wear off.
3, prohibits anti-static overalls attach or wear any metal objects.
4, wear anti-static clothing, you should also supporting the use of anti-static shoes, but it should be a conductive ground.
5, anti-static overalls should be kept clean and maintained antistatic properties, after use with a soft brush, a soft cloth moistened with neutral detergent, the material does not damage clothing fibers.
6, wearing a period of time to deal with anti-static clothing, you can test, if the static performance does not meet the standard requirements, you can prevent the use of static clothing.
