Classification of Antistatic Man-Made Materials
In antistatic engineering, a large number of artificially manufactured or modified materials are used. Generally, there are two main manufacturing methods for man-made materials: one is to add charged materials or substances to the original material, such as carbon black, graphite, carbon fibers, or metal powders, metal fibers, or antistatic agents and other compounds. The added materials or products are permanent. The other method is surface coating, such as applying surfactants to the surface of tool handles. This utilizes molecular polarization and hydrophilic groups to form a monomolecular conductive layer on the surface, achieving the purpose of antistatic properties. This method is time-sensitive and will wear off.
