  • There is no need to carry out daily maintenance and maintenance when in use, which can not only save a lot of time, but also reduce the cost, but also has good stability, strong corrosion resistance, greatly extend the service life. According to the different technology is divided into different types, can be selected according to their own needs, has better flexibility and elasticity. The main function of annealing wire is to control its hardness, when the annealing wire is made of steel wire.

  • 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 silver powder is actually a mixture of aluminum powder and polymer after painting the film, the film is brittle, easy to appear adhesion problems, and corrosion resistance is also slightly poor. Galvanizing refers to the surface of metal, alloy or other materials coated with a layer of zinc to play the role of beautiful, rust prevention and other surface treatment technology. Zinc dissolves easily in acids and also in bases, so it’s an amphoteric metal. Zinc changes little in dry air.
