In the alkaline galvanizing process, the production line is designed according to the plating speed of the workpiece, which can ensure that the coating thickness of each batch of workpieces is uniform.But sometimes it will be found that the plating speed of the workpiece will be slower. Is this an excessive addition of alkaline zinc plating additive?
In the production process of galvanizing, the color zinc workpiece needs to have good decorative properties, that is, it needs to have good brightness and bright color appearance.And sometimes the brightness of the color zinc workpieces produced is relatively poor. Is this because the trivalent chromium color zinc passivation solution is used improperly?
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?
Do you know the function and concentration control parameters of each component in the plating solution when using acid zinc plating brightener?
