The nickel salt in the plating solution is consumed quickly, Is this the poor performance of the high-phosphorus electroless nickel plating solution?

2022-02-17

    In the production process of the chemical nickel process, we sometimes find that the nickel salt in the plating solution is consumed very quickly, the amount of added high-phosphorus electroless nickel plating solution is also relatively large, the deposition rate and coating quality of the electroless nickel layer of the product are unstable. Is this the poor performance of the high-phosphorus electroless nickel plating solution?

    Bigolly Technology made an analysis based on the field experience and the characteristics of the product high-phosphorus electroless nickel plating solution Ni-811,In fact, this is not necessarily because the performance of high-phosphorus electroless nickel plating solution is relatively poor.The main reasons for the rapid consumption of nickel salts in the plating solution are the following three:


    1. A layer of chemical nickel has been deposited on the tank wall or equipment of the chemical nickel tank. During the production process, the deposited chemical nickel layer will continue to deposit chemical nickel, resulting in rapid consumption of nickel ions.At this time, production should be stopped immediately, the plating solution should be filtered into a clean empty tank, and the electroless nickel deposited by the plating tank or equipment should be soaked in 1:1 nitric acid solution. After the plating tank was soaked and cleaned, the plating solution should be returned The plating tank continues production.

    2. The load of the electroless nickel plating tank is too large, the plating solution is overloaded, the deposition rate is too fast, and the nickel ion consumption is fast, so the plating solution will be scrapped in advance.During production, the loading amount should be calculated reasonably, and the loading amount of the plating solution should be controlled within the process range as far as possible.

    3. The temperature of the electroless nickel plating solution is too high or the pH value is too high, and the deposition rate of the electroless nickel plating layer is too fast, which is easy to trigger the spontaneous decomposition of the plating solution.In the production process, the temperature and pH value of the plating solution should be strictly controlled to ensure the uniform deposition of the electroless nickel coating and prolong the service life of the plating solution.

    Therefore, in the production process of using high-phosphorus electroless nickel plating solution, the consumption of nickel salt in the plating solution is relatively fast, It is not necessarily that the performance of the high-phosphorus electroless nickel plating solution is poor, it may be that the control of the plating solution is not in place.If you are interested in high-phosphorus electroless nickel plating solution, please contact Bigolly customer service, you can get free samples and detailed technical information!
