Galvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metals, alloys or other materials to play the role of aesthetics and rust prevention. The main method used is hot-dip galvanizing. Galvanizing technology can avoid the contact between the steel matrix and any corrosive solution and protect the steel fastener matrix from corrosion.
Product details
Zinc is soluble in acids and alkali, so it is called an amphoteric metal. Zinc changes little in dry air. In moist air, a dense basic zinc carbonate film forms on the surface of zinc. In the atmosphere containing sulfur dioxide, hydrogen sulfide and Marine atmosphere, zinc corrosion resistance is poor, especially in the high temperature and high humidity atmosphere containing organic acid, zinc coating is easily corroded.
The standard electrode potential of zinc is -0.76V, for the steel substrate, zinc coating belongs to the anodic coating, which is mainly used to prevent the corrosion of steel, and its protective performance is greatly related to the thickness of the coating. The protection and decoration of zinc coating can be improved significantly after passivation, dyeing or coating with light protector.
