The main method of galvanizing is hot-dip galvanizing, which also includes cold-dip galvanizing and mechanical galvanizing. From the type of galvanized products, it can be divided into galvanized sheet coils and galvanized structural parts. The main terminal flows include infrastructure, real estate, automobiles and other fields.
Hot-dip galvanizing: also called hot-dip galvanizing and hot-dip galvanizing: is an effective metal anti-corrosion method, mainly used in metal structural facilities in various industries. It is to immerse the rusted steel parts in the molten zinc liquid at about 500℃, so that the zinc layer is attached to the surface of the steel components, thereby achieving the purpose of anti-corrosion.
Cold galvanizing: It is electrogalvanizing, with a small amount of zinc, only 10-50g/m2, which is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts, forming a uniform, dense, and well-bonded metal layer. The process can prevent corrosion, improve wear resistance, conductivity, reflectivity and enhance beauty.
Mechanical galvanizing In a rotating drum filled with plated parts, glass balls, zinc powder, water and accelerators, the glass balls, as impact media, rotate with the drum, rubbing and hammering against the surface of the plated parts to generate mechanical physical energy. Under the action of chemical accelerators, the plated zinc powder is "cold welded" to the surface of the plated parts, forming a smooth, uniform and delicate coating with a certain thickness.
