In normal hot-dip galvanizing operation, it is stipulated that the mass fraction of iron in the hot-dip galvanizing bath should not exceed 0.05%. As the production progresses, when the mass fraction of iron in the hot-dip galvanizing bath accumulates to 0.2%, the production can no longer be carried out. In the production process of hot-dip…

The zinc bath or zinc pot used for hot dip galvanizing generally uses low carbon steel with very little carbon content. . This is to reduce alloying and hot corrosion during use. If the material of the zinc pot is used improperly, the service life of the zinc pot will be greatly shortened. Steels with…

Acid bright copper plating solution should pay attention to the following three points in the maintenance: . 1) Strictly controlling process specifications is an important means to maintain the electroplating solution. Although the content of copper sulfate in the plating solution can vary within a relatively wide range, too large a difference in the content…
