The galvanized wire manufacturer is made of high-quality low-carbon steel wire rod. It is made of high-quality low-carbon steel, which is drawn, pickled and rusted, high temperature annealed and hot-dip galvanized. Processed by cooling and other processes. Galvanized wire is further divided into hot-dip galvanized wire and cold-galvanized wire (galvanized wire). The galvanized iron wire has good toughness and elasticity, and the maximum amount of zinc can reach 300 g/m2. It has the characteristics of thick galvanized layer and strong corrosion resistance.
Compared with other galvanizing processes, galvanized wire manufacturers have lower standards for pre-plating cleaning of low-carbon steel wires during galvanizing. However, in the current trend of increasing the quality grade of the galvanized layer, some pollutants are introduced into the plating tank. Obviously become harmful. Since cleaning the galvanized layer wastes a lot of time and reduces the yield, it is very important to properly clean the substrate and perform an effective rinsing operation before plating.
The surface of the galvanized wire manufacturer before galvanizing deposits to the surface to remove surface defects, surface inclusions and other defects can be found and treated by conventional techniques; excessive foam is due to the soap and saponified fat surfactants into the bath And formed. Moderate foam formation rates may be harmless. The large amount of tiny homogenous particles present in the bath stabilizes the foam layer and is treated with activated carbon to remove surface active substances. Or the foam is not stable by filtration, which is an effective measure; other measures should be taken to minimize the amount of surfactant introduced. The introduction of organic matter can significantly reduce the plating speed. Although the chemical formulation is advantageous for high deposition speeds, the thickness of the coating cannot be satisfied after the organic matter is taken, so that the activated carbon can be used to treat the bath.
The above is the galvanized wire manufacturer introduced to you about the galvanized wire before galvanizing some things to pay attention to, I hope to help everyone!
