In the process of using bright nickel plating additives, dirt will be deposited on the surface of the workpiece, which seriously affects the appearance and performance of the coating.What causes this phenomenon?
According to the field experience and the characteristics of the product bright nickel plating additive Ni-301, Bigolly Technology has made analysis, mainly for the following three reasons:
1. The current density is too high.Although sometimes the electroplating time can be shortened by increasing the current density, it is easy to cause scorching at the edge of the workpiece, and the coating will be mixed with additives, resulting in a dirty coating.
2. The plating solution is too dirty.The decomposition products of additives and brighteners, grease, etc. in the bath are accumulated in the bath without good filtration treatment.In the nickel plating process, these things will be mixed in the coating and cause the coating to look dirty.Therefore, a good circulating filtration system should be maintained in the production process to ensure the cleanness of the plating solution.
3. The anode bag is damaged.In some production lines, the anode bag is damaged during production without timely treatment, and the generated anode sludge will enter the plating solution.In the process of nickel plating, these sludge are easy to be mixed in the coating, resulting in dirty coating.Therefore, the anode bag shall be checked during production and the damaged anode bag shall be replaced in time.
Therefore, in the process of using bright nickel plating additives, we should pay attention to these three points when the coating surface is dirty, and eliminate faults in time to reduce losses caused by faults.If you are interested in bright nickel plating additives, please contact the Bigolly customer service for free samples and detailed technical information!
