If the plating solution is easy to decompose when using medium phosphorus electroless nickel plating solution, pay attention to this detail

2022-03-30

    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.

    Mr. Chen from Chaozhou encountered such a problem. The plating bath has not been produced for a few cycles, and nickel powder is easily generated on the tank wall and bottom of the plating tank, and the chemical nickel layer of the workpiece is relatively rough.In this way, Mr. Chen turned to Bigolly's engineers for help.

    After Bigolly engineers rushed to the scene, through on-site analysis, they found that the nickel ion concentration of the plating solution was normal, the pH value and temperature of the plating solution were also normal, and the addition of stabilizer was also normal.These factors are normal, how can the plating solution be easily decomposed?Careful engineers checked the heating rod and found that a thick coating had been deposited on the surface of the heating rod.


    After asking the operators on site, the engineer found that Mr. Chen's medium-phosphorus electroless nickel plating is a manual production line, and the outer layer of the heating rod used is metal, and the electroless nickel layer is easily deposited during the production process.The operator just neglected this point, and did not take the heating rod out of the plating tank and treat the electroless nickel coating on the surface of the heating rod after each production.In this way, in the next production, the surface of the heating rod will continue to deposit electroless nickel.The nickel salt of the plating solution will be consumed faster, and the plating solution will be easier to decompose.

    After careful guidance of the engineer, in the production of medium phosphorus electroless nickel plating solution, Mr. Chen will process the electroless nickel layer deposited on the surface of the heating rod at the end of each production.Now the service life of the plating solution is extended by 4-8 cycles, which greatly reduces the production cost.

    Therefore, in the production process of using medium phosphorus electroless nickel plating solution, although the process is relatively simple, there are many details required.Ignoring a certain detail, such as forgetting to take out the heating rod at the end of production, will speed up the consumption of the potion, shorten the service life of the plating solution, and increase the production cost, which is not worth it!
