Hot Dip Galvanized Coil Description
Hot dip galvanizing is to make the molten metal react with the iron substrate to produce an alloy layer, so that the substrate and the coating are combined. Hot galvanizing is to pickle the steel and iron parts first. In order to remove the iron oxide on the surface of the steel and iron parts, after pickling, it is cleaned by ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent into the hot dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
Hot-dip galvanizing is one of the effective means to delay the environmental corrosion of iron and steel materials, it is the surface of the cleaned, activated iron and steel products immersed in molten zinc, through the reaction and diffusion between iron and zinc, in the iron and steel products surface plating good adhesion of zinc alloy coating. Compared with other metal protection methods, the hot-dip galvanizing process has advantages in the protection characteristics of the combination of physical barrier and electrochemical protection of the coating, the bonding strength of the coating and the substrate, the compactness, durability, maintenance-free and economy of the coating, and its adaptability to the shape and size of the product. At present, hot-dip galvanized products mainly include steel plates, steel strips, steel wires, steel pipes, etc., of which hot-dip galvanized steel plates account for a large proportion.
The production process of hot galvanizing is as follows:
Mother material → degreasing → water washing → pickling → water washing → rinsing → flux solution → drying → hot galvanizing → cooling → inspection → packaging
Scope of ApplicationFor a long time, 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 automobile, construction, household appliances, chemical industry, machinery, petroleum, metallurgy, light industry, transportation, electric power, aviation and marine engineering and other fields.
