In the production process of using alkaline galvanizing additives, sometimes the main salt concentration of the plating solution is controlled within the normal working range, but the galvanized layer of the workpiece will appear black in the low area.Is this an improper use of alkaline galvanizing additives?
How can we control the current when we use alkaline galvanizing additives for barrel plating production?
When aluminum alloy workpieces are produced with electroless nickel plating solution, the plating solution is easy to be unstable. If the control is not good, the plating solution will be scrapped in advance.So how can we improve the stability of the plating solution?
When we use alkaline zinc plating additives to produce, electrolytic treatment of plating solution is a commonly used method to remove impurities.When energized, impurities are deposited, entrapped or reduced to relatively harmless substances on the cathode electrolytic plate.So how should we correctly use electrolysis to treat impurities in the plating solution?
When aluminum workpieces are produced with electroless nickel plating solution, in order to obtain better bonding force, the pre-plating treatment of workpieces is very important.So what pre-plating processes should we pay attention to in production?
Do you know the function and concentration control parameters of each component in the plating solution when using acid zinc plating brightener?
