  • The silver powder is actually a mixture of aluminum powder and polymer after painting the film, the film is brittle, easy to appear adhesion problems, and corrosion resistance is also slightly poor. Galvanizing refers to the surface of metal, alloy or other materials coated with a layer of zinc to play the role of beautiful, rust prevention and other surface treatment technology. Zinc dissolves easily in acids and also in bases, so it’s an amphoteric metal. Zinc changes little in dry air.

  • The iron is clean and clean, and then solvent treatment, after drying immersed in zinc liquid, iron and molten zinc reaction to produce an alloyed zinc layer, the process is: degreasing – washing – pickling – assisted plating – drying – hot dip galvanizing – separation – cooling passivation. The thickness of the alloy layer of hot plating wire mainly depends on the chemical composition of the steel silicon content, the size of the steel cross-sectional area, the roughness of the steel surface, the temperature of the zinc pot, the time of dipping zinc, cooling speed, cold rolling deformation, etc.
