10 Tips for Selecting High-quality Anti-static Work Clothes
Anti-static work clothes are not a one-time wear. If worn improperly or washed many times, their static conductivity may be reduced and fail to meet safety requirements. Therefore, Tianjin Strength Technology Company teaches you how to select high-quality anti-static clothes so that anti-static work clothes are more durable and have longer-lasting anti-static performance. The following points should be noted in the selection:
(1) Under normal circumstances, in places where explosive gas mixtures appear continuously, frequently in a short period of time, or exist for a long time, and in places where explosive gas mixtures may appear, when the minimum ignition energy of flammability is below 0.25mJ, anti-static clothes should be worn. Anti-static work clothes should choose gray silk conductive fiber as the best quality. In terms of appearance quality of anti-static work clothes, the fabric should be free of damage, spots, dirt or other defects that affect the anti-static performance of the fabric.
(2) Clothing should be made of anti-static fabrics. Generally, no lining is used. When lining must be used, the exposed area of the lining should not exceed 20% of the total inner surface area of the clothing. If a large area needs to be interlined, a lining with the same conductive fiber should be selected as the lining. Generally, it can be distinguished by the naked eye.
(3) Anti-static work clothes with different levels of anti-static fabrics should be selected according to the electrostatic sensitivity of different processing objects in different places. The smaller the spacing between the conductive fibers, the better the effect. The more obvious the dew, the better the effect. Moreover, the kind that is interwoven with each other is required.
(4) It is forbidden to attach or wear any metal objects on anti-static work clothes. Anti-static clothes with metal buckles are not the high-quality products you need.
(5) The fabric should be flat and have a good feel. The cotton content of a good feel is relatively high. The higher the polyester content, the easier it is to generate static electricity.
(6) Check whether the manufacturer has the "National Industrial Product Production License" and "Special Labor Protection Equipment Safety Mark Certificate". It is difficult to guarantee the product quality of manufacturers without relevant qualifications.
(7) Check whether it is equipped with an instruction manual. It is difficult to guide your use without a relevant instruction manual. Without the manufacturer's name and contact information, after-sales service is difficult to guarantee.
(8) Before wearing anti-static work clothes purchased in bulk, several pieces should be randomly selected to test the charge. Only those with a charge below 0.6 are qualified. After wearing for a certain period of time, especially when the wearer feels an electric shock when taking off the clothes, retesting should be carried out.
(9) When choosing conductive metal fiber cloth, you should choose a fabric with very fine metal fiber, because the finer the metal wire, the lower the voltage at which the corona discharge starts, which can be discharged at about 3-4KV, and the effect of removing static electricity is more obvious.
(10) When using antistatic agent to treat polyester and polyester-cotton cloth, its effect is very poor when the humidity is not high, and its anti-static durability is not as good as that of conductive metal wire cloth.
If you pay attention to the above 10 points when choosing anti-static work clothes, then the anti-static work clothes you choose will definitely be qualified and high-quality.
