When the zinc layer is seriously damaged and endangers the iron matrix, the zinc will produce electrochemical protection on the matrix, the standard potential of zinc is -0.76V and the standard potential of iron is -0.44V. When zinc and iron form microbatteries, the zinc will be dissolved as the anode, and the iron will be protected as the cathode. Obviously, the atmospheric corrosion resistance of hot dip galvanizing is better than that of electric galvanizing.

The wire after the first plating, its strength limit is also higher than the first plating, plated zinc and then made of wire not only toughness and high strength. There is a lower figure in the strength limit of galvanized iron wire because of the quality of zinc, because the strength of zinc technology is several times smaller than the wire itself. It is difficult to hot-dip galvanize drawn wires, and it is impossible for finer and very fine wires to be coated with the desired thickness of smooth zinc.

After annealing, iron wire will become soft, flexibility will increase, iron is a more active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron in the dry air is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements, its production cost is lower, use and scale is wider, better protection function, so it is an important material for iron and steel parts in a strict working environment.

(1) In the painting construction should pay attention to ventilation, moisture-proof, fire prevention. The working environment and painting tools should be kept clean, the pressure of the air pump should be controlled within 0.63MPa, and the safety valve should be checked for failure.

Large roll galvanized wire phosphating film is dark gray to black gray, the thickness is generally 5-20μm, has better corrosion resistance in the atmosphere. Membrane is a microporous structure, strong adsorption ability to paint, such as used as paint bottom, corrosion resistance can be further advanced. Metal oxidation treatment: Add steel products to NaOH and NaNO2 mixed solution, heating treatment, the surface can form a layer of thickness of about 0.5-1.5μm blue oxide film, in order to reach the purpose of steel corrosion prevention, this process is called blue treatment, referred to as blue.

Cold galvanized wire has good toughness and elasticity, high zinc content can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Cold galvanized wire is widely used in construction, handicrafts, wire mesh preparation, the production of galvanized hook mesh, wall mesh, highway guardrail, product packaging and daily civilian and other fields.
