  • 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.

  • During this process, each time the wire is pulled over, the surface hardens due to the high friction temperature. So basically every time you pull it you have to annealing it in the furnace. On the one hand, it is to reduce the surface hardness. On the other hand, during the process of wire pulling, only the surface is deformed, and the center is unchanged. So there’s a lot of stress inside. Therefore, it is necessary to rely on annealing to eliminate the internal stress, so that the wire becomes soft again to eliminate the stress before being drawn again.
