In the process of using acid copper brightener, the appropriate amount of chloride ion in the plating solution can reduce the stress of the copper coating, improve the toughness of the copper coating, and also improve the brightness and flatness of the copper coating.However, when the chloride ion content is too high, it will lead to rough coating, dendritic stripes and loss of brightness.So how do we remove the excess chloride ion in the plating solution?
In the process of using decorative chrome plating additives, the surface of the workpiece coating will appear circular.This circular phenomenon can not be removed even by wiping. After the chrome layer is removed, it is found that this circular phenomenon on the coating disappears.So how can there be such a circular phenomenon on the coating surface?
In the production process of using acid tin plating additive, black spots are easy to appear on the workpiece coating. After washing, black spots still exist. What is the reason?
In the process of using nickel plating additives, sometimes the contact point between the workpiece and the copper hook of the hanger will be dark and black. What is the reason?
In the process of using decorative chrome plating additives, sometimes the coating surface of the workpiece looks very rough, which will seriously affect the decorative effect of the workpiece.What causes this?
In the process of using acid tin plating additive, sometimes the coating of the workpiece will be rough and porous. What is the reason?
