Embodiment Construction
[0014] Preparation of nickel sulfamate electroforming solution: add 10,000 g of nickel sulfamate, 250 g of nickel chloride, 750 g of boric acid, and 0.75 g of saccharin in an electroforming tank with a volume of 50 L, add 15 L of deionized water, and stir ( 70r / min) to 50°C and hold for 10h. Take a 3000mL beaker and wash it with deionized water, dry it, add 22.5g sodium lauryl sulfate, 2.5g butynediol, add 1500mL deionized water, stir and heat to boiling, wait for sodium lauryl sulfate and butynediol After the diol is dissolved, slowly pour it into the prepared nickel sulfamate solution, and then add deionized water to make the solution 25L. Stir fully and keep warm (50°C) for 12h.
