In recent years, galvanized trivalent black passivation process has been widely used because of its advantages of low cost and good performance.In the process of using zinc plating trivalent black passivation, in order to make the passivation solution have better stability and lower failure rate, we need to understand the influence of various process conditions on the coating.So how do they affect the coating?
In the production process of using acid zinc plating chemicals, we sometimes find the presence of copper impurities in the acid zinc plating solution. What effect does it have on the plating solution?
In the production process of using alkaline zinc plating brightener, we often see that the galvanizing tank is followed by several filters to filter the plating solution. Have you ever wondered, what is the effect of filtering alkaline zinc plating solution?
We all know that potassium chloride galvanized brightener is widely used for its advantages of low preparation cost, fast lightening, and good brightness.In order to effectively reduce the occurrence of failures, what details should we pay attention to when adding potassium chloride galvanized brightener?
After we use alkaline zinc plating brightener to produce for a period of time, there will always be some useless things in the plating solution, even harmful, these things are impurities. So how are these impurities colored?
A customer consulted that in the production process of using zincate zinc plating brightener, the bonding force of the galvanized layer of the workpiece is always relatively poor, which seriously affects the quality of the galvanized layer of the workpiece.
