In the alkaline galvanizing process, sometimes the workpiece is very clean in the pretreatment, but the coating foams after alkaline galvanizing.Is this caused by excessive addition of alkaline galvanizing additives?
When aluminum workpieces are produced using medium-phosphorus electroless nickel plating solution, sometimes the coating appears mottled. Although it does not affect the bonding force and corrosion resistance of the workpiece, it seriously affects the appearance of the workpiece.So, how does the coating of the workpiece appear mottled?
In the production process of using methanesulfonic acid matte tin additive, we should strictly control the parameters of each process condition, so that the tin plating layer has the characteristics of fine crystallization, good solderability, simple maintenance and low consumption,and can reliably meet customer needs.In the production process, what effect does each process condition have on the tinning process?
In the production process of using medium phosphorus electroless nickel plating solution, there will always be particulate impurities in the plating solution.What effect do these particles have on the plating solution?
In the production process of our use of methylsulfonic acid tin brightener, the plating solution needs to be maintained and maintained.If the electroplating solution is not well maintained, the consumption of brightener will increase, and the quality of the coating will be unstable, which not only wastes raw materials, but also increases production costs.So how should the bath be maintained and managed?
In the production process of using sulfate tin plating brightener, sometimes iron impurities will be produced in the plating solution, so what effect does iron impurities have on the plating solution?
