The melting point of zinc is 419.5 ° C, and the chemical properties are vivid. In the air at room temperature, a thin and dense basic zinc carbonate film is formed on the surface, which can prevent further oxidation. When the temperature reaches 225 ° C, zinc oxidizes violently, showing white zinc oxide. After high temperature grilling, the material of the anti-corrosion layer on the surface of the galvanized sheet is oxidized, so the galvanized sheet cannot withstand high temperature, and the surface will change color when heated, or other substances with protective properties on the surface will easily turn yellow after oxidation.
The surface of the galvanized coil should be removed from oil or wax components and other stains or dust, which can improve the adhesion of atomic ash.
