  • 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.

  • After annealing, iron wire will become softer and more flexible. Iron is a more active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements in dry air, its production cost is low, the use and scale is relatively wide, better protective function, so it is an important material for steel parts used in strict working environment.

  • Scope of use: Because the obtained coating is thicker, hot-dip galvanizing has very good protective function than electric galvanizing, so it is an important maintenance coating for iron and steel parts in strict working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding and other occupations. In agriculture, such as pesticide irrigation, greenhouse and construction industry, such as water and gas transportation, wire casing, scaffolding, Bridges, highway guardrail and other aspects, have been widely used in these years.
