  • If the zinc coating is good, but in 3% nitric acid when the light, the coating has dark shadow, passivation occurs when the film is brown, may be caused by foreign metal impurities such as copper or lead in the galvanizing liquid. When problems occur in the process of galvanizing large coil galvanized wire, the temperature and current density are checked first, and then the content of zinc and sodium hydroxide in the plating solution is measured and adjusted through the analysis of the plating solution. Whether DPE content is low can be determined by hull cell test.

  • The price of galvanized iron wire performance is the key to win, galvanized wire only with good performance, in order to win the market, in order to obtain customer praise. In galvanized wire, the main function of carbon in increasing hardness, less is less easy to rust, the main function of chromium is acid and alkali resistance; Nickel’s main function is high temperature resistance, acid and alkali resistance and conductive use; The main function of iron is magnetic conductivity; The main functions of titanium are low density, high hardness and strong corrosion resistance. The main function of copper is magnetic and electrical conductivity. Different chemical components have different functions, which together form the characteristics of galvanized wire.
