The main purpose
Galvanized pipes are usually used to loosen gas and heating. Galvanized pipes are also used as water pipes. However, after a few years of use, a large amount of rust will be generated. The yellow water that flows out will not only contaminate sanitary ware but also breed bacteria on the inner wall. . Corrosion can also cause excessive heavy metal content in the water, further harming human health. The Ministry of Construction of our country has banned the use of galvanized pipes as water pipes since 2000.
The advantage of sulfate zinc plating is that the current utilization rate reaches 100% and the deposition rate is very fast. However, because the crystallization of the coating is not fine enough, the deep plating ability is poor, and it is only suitable for pipes and wires with simple geometric shapes. After the process improvement, iron salt is also added to the original solution, which not only inherits the advantages of traditional sulfate zinc plating but also strengthens the ability of deep plating. After continuous improvement, the coating grains used for wires and tubes are more delicate and shiny than before.
