Compared with other galvanizing processes, the cleaning requirements for low carbon steel wire before plating are lower. However, in the current trend of improving the quality of galvanized layer, some pollutants in small plating tank are brought in. Obviously become something harmful. Since cleaning the galvanizing layer is time-consuming and reduces production, proper cleaning and effective rinsing of the substrate prior to plating is very important.
Galvanized wire is made of high quality low carbon steel wire rod processing, is made of high quality low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling process and other processing. Galvanized wire is divided into hot galvanized wire and cold galvanized wire. Galvanized iron wire has good toughness and elasticity, Z high zinc content can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.
Galvanized wire galvanized before the surface of the sedimentary layer to local removal of surface film layer, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank. Moderate rates of foam formation may be harmless. The presence of a large number of small homogeneous particles in the tank, stabilizing the foam layer, using activated carbon to remove surface active substances, or filtering to make the foam less stable, are effective measures.
