In the production process of using electroless nickel plating solution, we need to analyze and adjust the plating solution regularly. What is the reason for the rapid consumption of nickel ions in the plating solution?
Bigolly Technology made an analysis based on the field experience and the characteristics of the product's electroless nickel plating solution Ni-809,There are 4 main reasons:
1. An electroless nickel layer is deposited on the tank wall or equipment. At this time, the deposited electroless nickel layer will continue to deposit electroless nickel, resulting in rapid consumption of nickel ions.The plating solution should be filtered and transferred to the tank immediately, and the electroless nickel plating deposited by the plating tank or equipment should be soaked with a 1:1 nitric acid solution.After the plating tank is soaked and cleaned, the plating solution is poured back into the plating tank, and an appropriate amount of electroless nickel plating solution can be added after analysis to produce.
2. The load of the plating solution is too large, the deposition rate is too fast, the consumption of nickel ions is fast, and the service life of the plating solution is also affected.During production, attention should be paid to controlling the loading of the plating solution. In the production of large tanks, it should be noted that the loading is evenly distributed and should not be too concentrated.
3. The carry-out loss of the plating solution is large.In this case, the production process should be checked, the speed of the product out of the groove should be improved, and the plating droplets on the workpiece or drum should be transferred to the cleaning tank as far as possible.
4. Decomposition of the plating solution.In this case, after the bath has been used for a period of time, there are many nickel particles suspended in the bath.The plating solution should be filtered and transferred, and the plating solution should be analyzed and adjusted. If it is serious, the plating solution should be discarded directly.
Therefore, we should pay attention to these four points when using electroless nickel plating solution to produce, which can effectively avoid the phenomenon of rapid consumption of nickel ions, reduce the occurrence of failures, and reduce production costs.
