In the production process of using medium-phosphorus electroless nickel plating solution, sometimes a layer of electroless nickel plating is easily deposited on the tank wall and tank bottom of the plating tank, which will affect the product quality and the service life of the plating solution.So, how should we avoid depositing electroless nickel coating on the tank wall and tank bottom during the production process?
Bigolly Technology made an analysis based on the field experience and the characteristics of the product's medium-phosphorus electroless nickel plating solution Ni-809,there are three main points:
1. Control the temperature of the plating tank to avoid excessive local temperature.During the production process, the temperature will be higher near the heating rod.If you do not pay attention to the stirring, the local temperature of the plating solution will be too high, so that the plating solution is easy to get out of control and the precipitation of electroless nickel is deposited on the tank wall or the tank bottom.Therefore, we should stir the plating solution many times during production to make the temperature of the plating solution consistent.
2. Cover the electroless nickel plating solution when production is stopped to prevent dust or solid particles in the air from falling into the plating solution.Because these dusts or solid particles will cause the natural decomposition of the plating solution, the plating solution will precipitate spongy nickel particles.During production, the plating solution should be filtered in circulation, and the plating solution should be taken out regularly, soak the plating tank with 1:1 nitric acid to remove the deposits on the tank wall and ensure the cleaning of the plating solution.
3. During the production process, the lining of the plating tank used may be damaged, exposing the base metal, so that the metal is deposited with an electroless nickel coating.The plating tank should be checked during production. If the plating lining is damaged, the plating should be replaced in time to reduce the loss of nickel salts and effectively reduce production costs.
Therefore, when we use the medium phosphorus electroless nickel plating solution, we can effectively avoid the deposition of electroless nickel plating on the tank wall or tank bottom of the electroless nickel plating tank.This can not only ensure the quality of the products, reduce the failure rate, but also prolong the service life of the plating solution and effectively save the production cost.If you are interested in medium phosphorus electroless nickel plating solution,please contact Bigolly customer service, you can get free samples and detailed technical information!
