  • Smelting technology is good, advanced equipment, advanced process of large stainless steel plant whether in the control of alloy elements, impurities removal, billet cooling temperature control can be guaranteed, so the product quality is stable and reliable, good internal quality, not easy to rust. On the contrary, some small steel equipment is backward, backward process, smelting process, impurities can not be removed, the production of products will inevitably rust.

  • Especially after passivation of galvanized layer, the surface of the oxide layer is thicker and compact, itself has high oxidation resistance. On the other hand, when the surface of the galvanized layer is damaged, exposing the inner iron matrix, because zinc is more active than iron, zinc will bear the role of sacrificing zinc anode, zinc will be oxidized before iron, so as to protect the iron layer will not be damaged.

  • Galvanized wire is coated with a layer of stable zinc on the outside of the wire, and the zinc layer is used to protect the wire and make the service life of the wire longer. In the production of galvanized wire, the wire should be pickled. Pickling is to use some acid mist or acid liquid to wash away some oxides on the surface of iron, that is, rust, and some other corrosion, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanized.

  • The management system of the rinsing water after the steel wire pickling should be regularly and regularly discharged after the rinsing water, and the rinsing water should be kept clean and low acid value as far as possible. The pH control is more appropriate. The concentration of plating aid should not be too high. Hot plating wire must be added ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled in the range of 50~80g/L. The addition of ammonium chloride or zinc chloride raw materials without the results of laboratory analysis shall be subject to criticism and education, and economic treatment if necessary.

  • Galvanized electric welding net is widely used in industrial production, agriculture, engineering construction, transportation, mining and other processing and manufacturing industries. Such as machinery and equipment protective cover, animal guardrail, pot flower guardrail, window fence, safety exit guardrail, poultry cage, egg basket and home office food industry basket, paper basket and design decoration. It is suitable for general engineering building wall, pouring concrete, multi-storey building, etc., which plays an important structural role in the thermal insulation system. In the construction of the building, the thermal insulation board of hot-dip galvanized electric welding grid is placed on the inside of the outer mold of the wall to be concreted. The external thermal insulation board and the wall are one kind of live, and the thermal insulation board and the wall are integrated into one body after the removal of the mold.
