Optional anti-static overalls knowledge you need to know

Antistatic overalls clothes in order to avoid accumulation of static electricity, antistatic fabric for the fabric and sewing clothes.
First, anti-static fabric
Many types of anti-static fabric, summed up in roughly three types:
The first is the choice of resin antistatic agent pick up the fabric by padding, baking and the appearance of adhering to the synthetic fabrics, the fabric has a certain anti-static effect. This approach is now used only for civilian clothing to beat clothes ridden, spark discharge, pollution, dust and other static representation suck.
The second is the polymer in the polyester or nylon increased internal antistatic agents, such as phosphate, sulfonate appearance active agent or a third monomer to obtain durability introduce antistatic fiber. Antistatic agents because of the increased base case will play most of repercussions or differentiation appearance active agent, so when you wash the fabric pack or alkaline scrubbing agent hanged, to avoid affecting the antistatic effect, the fiber suitable for clean clothes, sterile clothes, can also be used for civilian garments.
The third is usually mixed with conductive fiber fabrics, such as anti-static fabric environmental impact regardless of location, is now available throughout sustained and recognized. This anti-static fabric antistatic function and the type of conductive fibers and conductive component (metal, graphite, carbon black, etc.) in the fiber segment condition, into homogeneous conductive component, conductive component cover, conductive compound component and a conductive component hybrid of four. Meanwhile rich in carbon black, graphite and other conductive components other composite conductive fiber filaments can be directly used for weaving, the warp every certain distance (eg 1.5 cm or so) embedded in a conductive filament, you can get a good antistatic effect, is currently used to weave cloth for the best anti-static clothing conductive fibers.
Second, the product is classified
Antistatic overalls moment according washability divergent samples can be divided into Class A and Class B. Meanwhile, A-level resistance to washing time should be ≥ 33.0 h, B-level resistance to washing time should be ≥ 16.0 h.
Third, anti-static overalls primary skill function
Antistatic overalls necessary for production according to national norms, existing national norms are useful GB 12014-1989 "anti-static overalls." The primary anti-static overalls skills needs is anti-static function, that is, each anti-static clothing electric charge, this requirement is directly related to the product's protection. In addition, the joints cracking strength, metal accessories, fabrics kimono material cracking strength is affecting the role of anti-static clothing worn and skills indicators.
Fourth, how to buy anti-static overalls
1, the layout needs
(A) wear Convenient, Comfortable, easy to get rid of, is conducive to human activities.
(2) shall not normally use metal garment accessories, it is necessary to use (buttons, zippers, etc.), you should ensure that when worn, metal accessories shall not directly revealed.
(3) Clothing should be fully utilized anti-static fabric, do not use fabric. It is necessary to use fabric (pocket, reinforced cloth, etc.), the fabric exposed area of ​​the inner surface of the full anti-static overalls exposed area of ​​20% or less; than 20% (such as winter clothes or special clothing) should be made with the fabric of the mask detachable.
2, the style needs
Typically overalls Tops for "three-tight," Bottoms is Straight; or "three-tight" jumpsuit.
Fifth, use and precautions
1, provided that under normal conditions, an explosive gas mixture in succession, frequently short time or a long time to show there was a place and explosive gas mixtures are capable of rendering the place, the minimum point of the combustible energy of 0.25 mJ, the following should Wearing anti-static overalls.
2, stop wear off in explosive areas antistatic overalls.
3, anti-static overalls Suppression attach or wear any metal objects.
4, wear anti-static clothing, you should also support the use of the anti-static shoes, along with the ground should also be conductive flooring.
5, anti-static overalls should adhere to clean, stick anti-static function, use with a soft brush, a soft cloth moistened with neutral washing agent rinse, no damage to the clothing material fibers.
6, wearing a period of time, the response to anti-static clothing for inspection, if the static function does not meet the specification requirements, you can not prevent the use of static overalls.
Electrically insulating footwear (boots) optional use
1, the selection of suitable species
Place in accordance with wearing divergent samples, the selection of divergent like electrical insulation shoes (boots). Generally speaking, the following withstand voltage 15 kV electrical insulation shoes and canvas shoes for electrical insulation frequency voltage 1 kV following operating environments; withstand voltage 15 kV or more electrically insulating boots rubber boots and polymeric materials for power frequency voltage above 1 kV operating environment. Also wear shoes and electrical insulation electrical insulation cloth shoes, their working environment should be able to adhere uppers boring.
2, there is evidence of solid product selection
Electrical insulation shoes are special labor protection supplies, implementation of industrial products production license and promised safety certification mark guidelines. In the purchase, you should first recognize whether the manufacturer of the product issued by the State Industrial product has promised to produce evidence (imported goods do not need to) and safety certification mark. On this basis, and then check whether the product title and address of the manufacturer, the production of industrial products promise card number, safety certification mark number, production date, production of goods to fulfill the norms of the Code, whether attached to the certificate and use the product manual, special attention to check whether there are shoes product title (or "electrical insulation" words or "EH" word), lightning symbol, shoe size and voltage resistance values. In addition, should demand to produce the merchandise dealers detection statements, and the promised goods manufacturers produce evidence (imported goods no such evidence) and safety signs certificates and checks useful life, with the demand for these two dealers supply copy of the material.
3, check the appearance of quality
Uppers can check whether a disability, color divergent, and the line re-pin jumper, break, pin code irregularity; help end whether there is a plastic, off-line; soles could have had sulfur, less sulfur , spray sulfur; like.
4, the use of precautions
Wearing any electrical insulation shoes (boots) should avoid touching sharp, high-temperature corrosive substances text, avoid shoes (boots) suffered injuries affect electrical function. Any help end corrosion, breakage of the Department, can no longer be used as electrical insulation shoes (boots) wearing.
