How to buy good anti-static clothing
With the development of the electronics industry, the use of anti-static clothing has become more and more widespread, but many customers are not aware of the quality of anti-static clothing, as long as the price is cheap, they will buy it, and the number of people wearing anti-static clothing is also increasing. The more workers with production lines and technical engineers, people are paying more and more attention to the hazards of static electricity, but can the work clothes you wear meet the anti-static standards?
At present, the anti-static clothing sold in many electronic stores and labor insurance shops is very cheap. Many customers have caused significant losses to the company in order to save costs. Not long ago, an electronics factory was wearing counterfeit anti-static clothing. Causes a problem with the product. The anti-static clothing purchased by this factory passed the electrostatic test before being cleaned, but after the anti-static clothing was cleaned, it completely failed to meet the anti-static requirements. The reason is that this type of anti-static clothing is The anti-static parameters obtained after ordinary fabrics are soaked in anti-static liquid are very unstable. After cleaning, they have no parameters and cannot be anti-static.
I often receive customers saying that the anti-static clothes they bought before have always failed the test after a period of time. The reason for the search * finally judged that the anti-static work clothes they purchased used inferior conductive yarns. If you want to buy anti-static work clothes, you need to find a professional manufacturer of anti-static products. Now I teach you a good way. In addition to measuring whether the anti-static clothing meets the anti-static requirements with a surface resistance tester, you must use a heavy hammer tester to measure whether the two cuffs are connected. If possible, you can clean the anti-static clothing. After cleaning for about 30 times, measure again. The strictest detection method is to measure whether the friction voltage of the anti-static clothing can reach below 50 volts after cleaning. If the voltage can be lower than 50 volts, it means that the anti-static clothing meets the anti-static standard. It will cause damage to the product. However, there are many kinds of anti-static clothing in the industry. Even professionals cannot distinguish with the naked eye. They can only be distinguished by a high-precision electrostatic tester. We hope that customers can't trust the supply lightly. The lies of the quotient must pass repeated tests.
