  • First, galvanizing can enhance the corrosion resistance of the product. Zinc has high potential and excellent anodic protection. When the surface of the product is galvanized, zinc will have an electrochemical reaction with oxygen and water in the environment, thereby forming a dense zinc oxide protective film, preventing the metal from further contact with external oxygen, water and other substances, slowing the corrosion rate of the metal. Galvanized products after wire drawing processing, because the surface of the product has a more dense zinc oxide protective film, it can better resist external corrosion and improve the corrosion resistance of the product.

  • Paint on the galvanized layer, the bonding force between each other has a great relationship with the baking temperature of the paint, and alkyd paint is coated after galvanized, and the adhesion is not a problem. After galvanized to do amino paint, paint adhesion is not very good. Do two bottom two surface, adhesion is good, if the two bottom two surface changed to two bottom three surface, that is, more paint, more baked once, again test adhesion is very bad, bad enough to tear the paint from the galvanized layer.

  • 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.
