  • The low-area coating of the alkali zinc workpiece is blackened, which is not due to improper use of alkali zinc plating additives

    The low-area coating of the alkali zinc workpiece is blackened, which is not due to improper use of alkali zinc plating additives

    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?

  • The plating speed on the alkaline zinc workpiece is very slow, not necessarily because the alkaline zinc plating additive is excessively added

    The plating speed on the alkaline zinc workpiece is very slow, not necessarily because the alkaline zinc plating additive is excessively added

    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?
