- Hot dip galvanizing, also known as hot dip galvanizing, is a method of obtaining a metal covering by immersing a steel member in a molten zinc solution. With the rapid development of high-voltage transmission, transportation and communication, the protection requirements for steel parts are becoming higher and higher, and the demand for hot-dip galvanizing is also increasing. Usually the thickness of electric galvanized layer is 5 ~ 15μm, and the large roll galvanized wire layer is generally more than 35μm, even up to 200μm. Hot dip galvanizing has good covering ability, dense coating and no organic inclusions.
There are three ways to twist the barbed rope: positive twist, reverse twist, positive and negative twist.
The number of each bundle of the blade barbed rope is 50, which is reduced by hydraulic compression and thus more convenient for loading and unloading. The forklift can load and unload easily. Under normal circumstances, when the export will be packaged and sold, so that the volume occupied in the container is relatively small, it can be easily placed and will not take up much space.
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.
