In the production process of using nickel plating brightener, the maintenance and management of the plating solution is very important.Sometimes the operation of the field operator is not standardized, which will bring a lot of trouble to the production.Such a thing happened in Mr. He's production line in Dongguan.
In the production process of using nickel plating additives, sometimes the parameters such as the composition of the plating solution and the operating conditions are normal, but the coating will appear fine spots, which affects the coating quality of the workpiece.Mr. Lin from Chaozhou encountered such a situation. Does it have anything to do with the nickel plating additives used?
Sometimes when we use medium phosphorus electroless nickel plating solution for production, we obviously control the process parameters within the working range according to the product instructions, but the plating solution is still easy to decompose, which is very distressing.
When we use alkaline galvanizing additives, in order to maintain good electrochemical performance in the plating solution and obtain a galvanized layer with excellent performance, it is necessary to strictly control the concentration of zinc, alkali and their ratio in the plating solution.In production, it is very important to accurately analyze the concentration of zinc and alkali, because the concentration of zinc and alkali fluctuates too much, and their ratio will also change, thus affecting the performance of the coating.
We all know that alkaline galvanized workpieces need to have good decorative properties, so they need to have good brightness and uniform passivated appearance.Sometimes, the coating of the galvanized workpiece on the customer's site turns black, and the film is not bright after the workpiece is passivated. They will think that this is caused by the improper use of alkaline galvanizing additives. Is this really the case?
In the production process of the alkaline galvanizing process, various failures will inevitably occur, such as poor bonding, scorching, and poor positioning.And sometimes the failure is not necessarily caused by the addition of alkaline galvanizing additives, but may be caused by improper operation on site. Mr. Lin is such an example.
