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?
Bigolly Technology made an analysis based on the field experience and the characteristics of the product's alkaline zinc plating additives BZ-515,There are two types of electrolytic treatment of general plating solutions: intermittent and continuous.
The batch method is to stop production when the plating solution is contaminated by impurities and affects the quality of the coating.The cathode is changed to a hanging electrolytic plate for electrolytic treatment, until the plating solution returns to normal, and then it is transferred back to electroplating production.
The continuous method is to add a small auxiliary tank next to the plating tank, this auxiliary tank is dedicated to electrolytic decontamination.A pump is used to pump the plating solution to be electrolyzed from the plating tank into the auxiliary tank, and an overflow port is opened above the auxiliary tank to allow the electrolytically treated plating solution to flow back to the plating tank, so that the plating solution can be recycled and electrolyzed to remove impurities.The advantage of the continuous method is that electroplating and electrolysis can be carried out at the same time without stopping production.
Therefore, we can use the above two electrolytic methods in the production process of using alkaline zinc plating additives, which can effectively remove impurities in the plating solution, maintain the stability of production, and reduce the occurrence of failures.If you are interested in alkaline zinc plating additives, please contact Bigolly customer service to get free samples and detailed technical information!
