  • In addition, before the wire enters the zinc liquid, a layer of insulation material containing zinc oxide reducing agent can reduce the heat loss and zinc ash floating. When the zinc solution contains 0.002%-0.005% aluminum, the brightness of the zinc layer can be increased obviously, and excessive zinc ash can be prevented from oxidation on the surface of the zinc solution.

  • Thorn rope also often appear in another type: 14*14# thorn rope, 12*12# thorn rope, 12*14# thorn rope, which 14# wire diameter is about 2.0 mm, 12# wire diameter is about 2.65 mm, there is a non-standard 2.25 mm is also commonly used linear. According to this specification conversion 14*14# thorn rope a kilogram out of 12 meters, 12*14# thorn rope a kilogram out of 8 meters, 12*12# thorn rope a kilogram out of about 5 meters.

  • First, galvanizing can enhance the corrosion resistance of the product. Zinc has high potential and excellent anodic protection. When the surface of the product is galvanized, zinc will have an electrochemical reaction with oxygen and water in the environment, thereby forming a dense zinc oxide protective film, preventing the metal from further contact with external oxygen, water and other substances, slowing the corrosion rate of the metal. Galvanized products after wire drawing processing, because the surface of the product has a more dense zinc oxide protective film, it can better resist external corrosion and improve the corrosion resistance of the product.

  • Crevice corrosion is a kind of corrosion in small area, especially in concealed position, which can form vicious corrosion cycle. Almost all the crevice corrosion can occur in a metal alloy, with gas containing active anionic neutral medium Z is easy to cause crevice corrosion, crevice corrosion often occurs in the aperture of 0.025 to 0.1 mm, because of long time gathered, the cracks will exist a series of impurities, coupled with the external environment of damp easily corrode the area of the gap is small.
