At present, hot-dip galvanized products mainly include steel plate, steel strip, steel wire, steel pipe, etc., of which hot-dip galvanized steel plate accounts for the largest proportion. For a long time, the hot-dip galvanizing process has been favored by people because of its low plating cost, excellent protection characteristics and beautiful appearance. It is widely used in the fields of automobile, construction, household appliances, chemical industry, machinery, petroleum, metallurgy, light industry, transportation, electric power, aviation and marine engineering.
Hot dip galvanizing is to make molten metal react with iron matrix to produce alloy layer, so as to combine the matrix and coating. Hot dip galvanizing is to first carry out pickling on steel parts. In order to remove iron oxide on the surface of steel parts, after pickling, it is cleaned in ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent to the hot dip galvanizing tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
