Shenzhen Multilayer Nickel additives, pearl nickel brightener Shenzhen, Shenzhen metal surface treatment materials factory Miss Zhang Huiqun 13686661868 http://www.diandu168.com Shenzhen High-filled bright nickel plating bath preparation 1. Add 2/3 with tank volume water, heated to 60 ~ 65 ℃, was added the required acid, nickel sulfate and nickel chloride, stirring until completely dissolved; adding 1 ~ 2ml / l hydrogen peroxide (30%) 2. When necessary, stirred for 1 hour, raise the liquid temperature to 65 ~ 70 ℃, heat 2 hours to remove residual hydrogen peroxide. Otherwise it will cause low power region and pinhole leak plated; 3. Add chemically pure activated carbon 1 ~ 2g / L, after stirring for 1 hour and then filtered; 4. Add water to the required volume, corrugated iron with a small current (0.6 ~ 1A / dm2) electrolytic treatment 2 to 3 hours, if the nickel salt of copper, zinc excessive impurities, then with a low current (0.2 ~ 0.4A / dm2) electrolysis process about 18 to 24 hours, until the coating is not black so far; 5. Add nickel plating additive, a small current (0.8 ~ 1A / dm2) electrolysis for about 10 minutes, you can try plating. NOTE: If the quality nickel salts and boric acid, hydrogen peroxide is not necessary and activated carbon treatment. Second, the Shenzhen High-filled bright nickel plating additives and complementary 86 primary light stabilizers: keep the coating brightness and leveling of daily production by 150-200 ml / kg when additional security. 86 Softener: lower tensile stress, increase flexibility, throwing ability and leveling of daily production by 150-200 ml / kg when additional security. Wetting agents: prevent coating pinholes, daily production by 30-50 ml / kg when additional security.
