When we use decorative chromium plating additives, the workpiece can obtain a bright chromium plating layer with good coverage.Sometimes the brightness of the chrome plating layer on the workpiece is very poor. What is the reason?
In the process of using organic acid matt tin additive, what matters should we pay attention to in production in order to ensure the smoothness and uniformity of the workpiece coating and superior solderability?
In the production process of using decorative chromium plating additives, hexavalent chromium is mainly used in the plating solution, which is very harmful to human health, and the waste water and waste gas discharged will also have a great impact.So what can we do to reduce the pollution of hexavalent chromium?
In the production process of using zinc nickel alloy color passivator, sometimes the passivation film of the workpiece will have uneven colors of black, yellow and blue. What causes this?
In the process of using alkaline zinc nickel alloy additives, the current efficiency of the bath itself is relatively low, only about 70%, and sometimes the current efficiency of the bath is lower. Is this caused by the low concentration of sodium hydroxide in the bath?
We can obtain uniform light blue to bluish blue passivation film with strong corrosion resistance when using zinc nickel alloy trivalent chromium blue passivator.What points should we pay attention to in the use process?
