Large coils of galvanized wire surface coating can see whether the quality of galvanized wire is good or bad. If the strength of the zinc attached to the wire is very poor, then the galvanized wire is best not to buy, because this galvanized wire must be inferior galvanized wire. Galvanized iron wire is also called hot dip zinc and hot dip galvanized: it is an effective way of metal anticorrosion, mainly used in metal structure facilities in various industries. The derusting steel is immersed in the molten zinc solution at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to play the purpose of anti-corrosion.

High quality galvanized wire generally attached to the surface of the wire zinc layer are relatively thick, so when you buy galvanized iron wire, just look at the thickness of the zinc layer machine, can generally judge the quality of galvanized iron wire is not high-grade. The duration of the protective effect of galvanized layer is greatly related to the thickness of the coating. In the selection of galvanized layer thickness to consider the impact of the environment. After passivation treatment of galvanized layer, a bright and beautiful color passivation film can be generated, which can significantly improve its protective performance and the performance of paddle decoration.
There are many kinds of zinc plating solution, according to its properties can be divided into two categories of cyanide plating solution and non-cyanide plating solution. The cyanide galvanizing solution has good dispersing ability and covering ability, the coating is smooth and meticulous, the operation is simple, the application range is wide, and it has been used for a long time in the production. However, because the plating solution contains highly toxic cyanide, the gas escaping from the plating process is harmful to workers’ health. Its waste water must be strictly treated before discharge.
