Matters needing attention when replenishing electroless nickel plating solution

How much do you understand about electroless nickel plating? What are the precautions for supplementing electroless nickel plating solution? Understand the knowledge of the product and use it better. Now let's take a look at it with us.

1. First take 100ml deionized water, then add 10ml plating solution, add 10ml ammonia water, 0.02g purpuric ammonia indicator, and finally titrate with 0.1mol 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 to electroless nickel plating is the value of adding sodium acetate by multiplying the obtained nickel sulfate by 0.74. The obtained nickel sulfate, multiplied by 0.37, is the supplementary value of the additive. (The total of brightener A and complexing agent B, take half of each). (unit ml) lactic acid is the supplement of nickel sulfate. Multiply the addend by 0.185 (in ml).
