Additional precautions for electroless nickel plating solution

Today, I will explain to you the precautions for the addition of electroless nickel plating solution. Friends who want to know more, please read the following article.

1. First take 100ml of deionized water, then add 10ml of plating solution, add 10ml of ammonia water, 0.02g of purpuric ammonia indicator, and finally titrate with 0.1mol of EDTA solution to purple as the end point.

2. The amount of nickel sulfate added to the electroless nickel plating solution (g)=(27—2.7 times the EDTA titration number) and then multiplied by the open cylinder volume L, and the equal value is the value of nickel sulfate to be added (in grams) .

3. The value of adding sodium acetate is the value of adding sodium acetate by multiplying the obtained nickel sulfate by 0.74. Multiplying nickel by 0.37 is the supplementary value of the additive. (The sum of brightener A and complexing agent B, take half of each). (unit ml) lactic acid is the supplementary value of nickel sulfate multiplied by 0.185 (unit ml).

The above is the content of electroless nickel plating introduced to you today, I hope it can bring you some help.
