  • Hot dip galvanized coating is also relatively thick, but there is an uneven situation, for example, the thickness of the thin is only 45 microns, thick can reach 300 microns or even thicker, the color of this product is relatively dark. There is also a lot of zinc consumed in the production process. Zinc will form an infiltration layer with the metal. Its advantage is that it has good corrosion resistance. Electrogalvanizing, it is through the plating tank in the zinc one-way plating on the outside of the metal products, this way of making products is relatively slow, but its thickness is more uniform.

  • If the zinc coating is good, but when the light comes out in 3% nitric acid, there is a dark shadow on the coating, and the film is brown when passivation occurs, which may be caused by foreign metal impurities such as copper or lead in the galvanized liquid. When there is a problem in the process of galvanizing, check the temperature and current density first, and then measure and adjust the content of zinc and sodium hydroxide in the bath through the analysis of the bath. Whether DPE levels are low can be determined by Hull cell test.
