In the production process of alkaline zinc plating, sometimes the main salt concentration of the alkaline zinc plating solution is controlled within the normal working range, but the galvanized layer in the low area of the workpiece will turn black,Is this an improper use of alkaline galvanizing additives?
In the process of using semi-bright nickel plating additives, usually in order to improve the corrosion resistance of the nickel plating layer, a semi-bright nickel layer is required in the system of double-layer nickel or multi-layer nickel.What are the components of the semi-bright nickel plating solution?
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?
