What are the standard products of anti-static clothing?
Modern manufacturing industry has higher and higher requirements for environmental cleanliness. Many companies have equipped operators with anti-static work clothes, and also changed the traditional old-fashioned canvas rubber shoes into clean and beautiful anti-static shoes. Anti-static shoes generally use PU or PVC materials to make soles. Together with anti-static clothing, they form a complete anti-static system. There are also anti-static wrist straps, anti-static hats, etc.
Anti-static shoes can be called in many ways according to different styles and materials, such as anti-static work shoes, anti-static four-hole shoes, anti-static middle towel shoes, anti-static mesh shoes, and dust-free anti-static boots, etc. Its applicable occasions include pharmaceutical factories, food factories, clean workshops of electronics factories, and some special laboratories.
After using anti-static shoes for a period of time, they must be tested and checked. The test method is briefly introduced as follows:
1. The environment requires a temperature of 20℃±2℃; relative humidity: 30%±3%. The test product is placed in the specified environment for more than 24 hours. If the test cannot be carried out in the specified environment, the test must be completed within 5 minutes after the test sample is removed from the environment.
2. Fill the test shoes with steel balls as required, place the test sample with the steel balls on the specified outer electrode, and connect the specified DC power supply between the inner and outer electrodes for 1 minute. According to the measurement circuit principle. Record and calculate the voltage and current values after the specified time.
In addition to regular testing of anti-static shoes, you should also pay attention to the small details during use. First, when wearing anti-static shoes, you need to wear thin nylon socks or conductive fiber socks, and you cannot wear wool and chemical fiber socks. Second, if you want to add insoles to the anti-static shoes, you must have conductive insoles. If you don't pay attention to these two points, the anti-static shoes will be no different from ordinary shoes, and the anti-static effect will not be achieved.
