  • Hot dip galvanizing is also called hot dip zinc and hot dip galvanizing: is an effective way of metal corrosion, mainly used in various industries of metal structure facilities. It is to immerse the steel parts after rust removal into the molten zinc liquid at about 500℃, so that the surface of the steel parts is attached with zinc layer, so as to play the purpose of anticorrosion. Hot dip galvanizing process: finished product pickling – washing – adding bath aid – drying – hanging plating – cooling – drug – cleaning – grinding – hot dip galvanizing completion. Hot dip galvanizing is developed from the older method of hot dip galvanizing. It has a history of 140 years since it was applied to industry in France in 1836. However, the hot dip galvanizing industry has been developed on a large scale in the past 30 years with the rapid development of hot dip galvanizing wire.

  • Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Solid particles or excessive foreign metal impurities in the electroplating solution can cause such problems. Solution: If the coating of large galvanized wire is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.

  • Hot-dip galvanized wire has longer service life and better corrosion resistance than ordinary steel wire. Hot dip galvanizing is a method of chemical combination of zinc metal and steel wire surface, through the formation of a strong and self-healing zinc-iron alloy protective layer on the steel wire surface, so as to prevent direct contact between the steel wire and the external environment, reduce the possibility of oxidation corrosion, and extend the service life of the steel wire.
