What is the friction voltage of anti-static work clothes?
Anti-static work clothes are widely used in the electronics industry, petrochemical industry, etc., but not all work clothes are anti-static work clothes. Data needs to meet the requirements. Two of the more important indicators are point-to-point resistance and charged charge. In addition to these two indicators, there is another indicator that often appears when purchasing anti-static work clothes, that is, friction voltage.
Friction voltage is not a standard for determining whether anti-static work clothes are qualified, but many strict electronic companies or factories will have requirements on the friction voltage of anti-static work clothes. To meet these requirements, we must first understand the friction voltage of anti-static work clothes. What? When two different materials or the same material rub against each other or in close contact and separate according to the prescribed test methods and parameters, the two materials are charged with the same amount of static charges of different signs, and a voltage will be generated between the two. This voltage is called the friction voltage, and the friction voltage is related to the material, the degree of friction, and the ambient temperature and humidity.
Specifically, the friction voltage of anti-static work clothes can refer to the voltage generated by two pieces of the same type of anti-static work clothes being rubbed continuously for more than 300 times within 1 minute. The friction voltage of conventional conductive silk is between 200V-300V, but If the friction voltage is less than 100V or even 50V, it is necessary to add a special process on the basis of ordinary conductive silk.
