  • The electrolytic deposition of large roll galvanized wire zinc-chin layer is basically the following two kinds of electrolyte: zinc is mainly in the form of zinc cation hydration in the solution; Zinc is mainly present in solution as complex anion. Acid electrolyte belongs to one class, complex cyanide and zincate electrolyte, and nickel sulfate electrolyte constitute the second class. Cyanide electrolyte and acid electrolyte are of great significance.

  • 5, the concentration of plating aid can not be too high, which is a factor that can not be ignored to reduce zinc consumption. The concentration of plating aid should not be too high. The galvanized line must be added with ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution should be controlled within the range of 50~80g/L. If ammonium chloride or zinc chloride is arbitrarily added without the results of laboratory analysis, it should be criticized and educated, and economic treatment should be given if necessary.

  • 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.
