The coating material is thermoplastic powder, and the coating has the characteristics of softening in heat and curing into film after cooling, which is mainly the process of physical melting and plastic forming film. Most of the dipping process uses thermoplastic powder, typical polyethylene, polyvinyl chloride, polytetrachloroethylene, suitable for non-toxic coating, general decorative, anti-corrosion, wear-resistant coating. The impregnation powder is divided into ① civil powder: mainly used for clothes hanging, bicycles, baskets, kitchen utensils and other coating, with better leveling and luster, ② engineering powder: used for highway and railway guardrail, municipal engineering, instruments and meters, cables, miscellaneous products and other coating, durability, corrosion resistance.
