Galvanized sheet is a steel plate with a layer of zinc on the surface.Galvanization is an economical and effective anticorrosion method that is often used. Galvanized steel plate is to prevent corrosion on the surface of the steel plate to extend its service life, A layer of metallic zinc is coated on the surface of the steel sheet. This kind of galvanized steel sheet is called galvanized sheet.
Zinc ball "cold plating" that is, "electroplating", that is, the zinc salt solution through electrolysis, to the plating layer, generally without heating.Cold galvanizing, also known as electric galvanizing, is the use of electrolytic equipment after the workpiece is removed oil, pickling into the composition of zinc salt solution, and connected to the negative pole of the electrolytic equipment;Place a zinc plate on the opposite side of the workpiece and connect it to the positive pole of the electrolysis equipment. Turn on the power supply, and use the directional movement of the current from the positive pole to the negative pole to deposit a layer of zinc on the workpiece.
