In our country, the requirements for indicators are now clearly specified for the production of anti-static clothing. According to the GB12014-2009 standard, the testing equipment for anti-static clothing mainly includes:
ZF-611 fabric triboelectric charge tester, ZF-618 tensile tester, ZF-613 point-to-point resistivity tester Conductive fabric is used to mix conductive fibers (such as metal or organic conductive materials) at equal intervals or evenly during spinning. Materials or subconducting materials) or antistatic synthetic fibers (such as acrylic-copper complex conductive fibers), or a combination of both fabrics.
First, anti-static protective clothing technical performance requirements Anti-static protective clothing product quality shall comply with the provisions of GB12014-2009 standards.
1, the appearance of protective clothing: There should be no damage, spots, dirt and other defects affecting taking performance.
2, anti-static properties: Each piece of anti-static clothing charged charge, washing performance, must meet the requirements.
3, seams: sutures should be careful, close, suture strength breaking strength is not less than 98N.
4. Structural design: It should meet the requirements of wearing lightweight, comfortable, convenient detachment and beneficial to the human body; style specifications: The general protective clothing is topped with "three tight", and the bottoms are straight pants.
5. Metal Accessories must not be used on clothing. When using (buttons, zippers, etc.), it must be ensured that the metal accessories are not exposed directly when worn.
6, clothing should use anti-static fabrics, do not use lining. When linings (clothes, reinforcements, etc.) must be used, the exposed area of ​​the lining shall be less than 20% of the exposed area of ​​all the inner surfaces of the antistatic clothing, and shall be made into a mask and lining if it exceeds 20% (such as cold static clothing or special clothing). Can be folded.
7, breaking force of the material: should meet the requirements.
Second, anti-static protective clothing quality supervision and inspection of anti-static protective clothing quality inspection should be carried out according to requirements, the number of samples per test for each species 2 sets.
Comprehensive judgment principle: Items 3, 4 and 6 must be qualified; items 1 and 5 must be allowed to fail.
Third, the use of anti-static protective clothing and precautions 1. Under normal circumstances, in the explosive gas mixture, frequent or short-term frequent occurrence or long existence of the place, and the explosive gas mixture may occur, the location of the smallest combustibles When the ignition energy is less than 0.25MJ, antistatic clothing should be worn.
2. It is forbidden to wear anti-static clothing in flammable and explosive places.
3. It is forbidden to attach or wear any metal objects on the antistatic clothing.
4, when wearing anti-static clothing, it should also be used with anti-static shoes. At the same time, the ground should also be a conductive floor.
5, anti-static clothing should be kept clean, maintain anti-static properties, after use with a soft brush, a soft cloth dipped in neutral detergent scrub, can not damage the fiber material.
6. After wearing for a period of time, you should check the anti-static clothing. If the anti-static performance does not meet the standard requirements, you can no longer use anti-static clothing.
Anti-static protective clothing is a protective clothing made of conductive fiber fabrics, used in workplaces that are prone to static electricity accumulation, to eliminate static electricity on clothes and human body, and to prevent fire and explosion.
