  • Pure zinc is more stable in dry air. In moist air or water containing carbon dioxide and oxygen, the surface will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer. Comparison of corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride; It is also resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in oceanic atmospheres; In high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded.

  • With the development of mining industry, the classification of pig iron is already very broad in our country, which can satisfy the demand of mechanical industry. In general, the iron used to produce large rolls of galvanized wire can be divided into two classes. A metal exercised directly from the iron ore through the iron making stroke, the composition of the ore is iron oxide, silica and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed into it. The material produced in this way is called ordinary pig iron, which is also the material for the first grade.
