In the production process of using acid copper brightener, we need to maintain and manage the plating solution and add the brightener correctly, so as to obtain a uniform bright coating with good filling and low porosity.Sometimes the stability of the plating solution is poor, and problems such as decreased brightness and rough coating will occur, which will affect the quality of the coating. What is the reason for this?
In the process of using hard chromium additive, the workpiece coating is prone to pinhole phenomenon, which will affect the appearance quality and production efficiency of the workpiece.What causes this?
In the process of using alkaline zinc-nickel alloy additives, sometimes the coating will be rough, which affects the coating quality and the effect after passivation. What is the reason?
When we use electroless nickel plating solution for production, because most of the reducing agents used are hypophosphite, phosphite ions will inevitably be generated in the plating solution.owever, when the concentration of phosphite is high, it will affect the deposition rate of chemical nickel. What range should the concentration of phosphite in the bath be controlled?
In the process of using barrel nickel plating brightener, sometimes the coating of the workpiece will be black and foggy, which seriously affects the quality of the coating.So what factors will affect the quality of the coating?
In the production process of using electroless nickel plating solution, sometimes the workpiece always has pits on the upward side. What is the reason?
