Hot dip galvanizing is a method of obtaining a metal coating on steel components by immersing them in molten zinc solution.
Process
Workpiece → degreasing → water washing → acid washing → water washing → immersion in auxiliary plating solvent → drying and preheating → hot dip galvanizing → finishing → cooling → passivation → rinsing → drying → inspection
The formation process of hot dip galvanized layer is the process of forming an iron zinc alloy between the iron substrate and the outermost pure zinc layer. The surface of the workpiece forms an iron zinc alloy layer during hot dip plating, which has good coverage ability, dense coating, and no organic inclusions.
In recent years, with the rapid development of high-voltage transmission, transportation, and communication industries, the requirements for protection of steel parts have become increasingly high, and the demand for hot-dip galvanizing has also continued to increase.
