  • 1. Principle. Because zinc does not change easily in dry air, and in humid air, the surface can form a very dense film of zinc carbonate, which can effectively protect the interior from corrosion. And when the coating is damaged for some reason and the matrix is not too large, the zinc and steel matrix form a micro cell, so that the fastener matrix becomes the cathode and is protected. It is widely used in automobile transportation and other industries, but what is needed is the trivalent chromium passivation layer, zinc nickel alloy plating closed coating, reduce the harmful and toxic layer of hexavalent chromium passivation.

  • 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.

  • In the atmosphere containing carbon dioxide and hydrogen sulfide and Marine atmosphere is not corrosion resistant, in high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded. In order to make large rolls of galvanized wire on the surface of the deposited layer to the local, remove the surface film layer, surface inclusions and other defects can be found and treated by conventional techniques. Excess foam is caused by soaps and surfactant saponable fats brought into the tank, and moderate rates of foam formation may be harmless.
