The summary of galvanized
Dec 22, 2016

Galvanized refers to the surface of metal, alloy or other material coated with a layer of zinc in surface treatment technology in one of the beautiful, rust, etc. Is mainly USES the method of hot dip galvanized.
Zinc soluble in acid, soluble in alkali, so call it gender metal. Zinc in the dry air almost no change. In the humid air, zinc and the alkaline zinc carbonate type film surface is generated. In the oceanic atmosphere, sulfur dioxide, hydrogen sulfide and poor corrosion resistance of zinc, especially in high temperature and high humidity atmosphere containing organic acid, zinc coating easy to corrode. Zinc standard electrode potential is 0.76 V, for iron and steel matrix, the zinc coating belongs to the anode sex coating, it is mainly used to prevent corrosion of steel, the pros and cons of the protective performance and coating thickness of the relationship.
