Detailed Product Description: | NICHEM 2008 acidic electroless nickel plating (phosphorus) acidic electroless nickel plating characteristics: long cycle life, up to 8-10 cycles (Metal Turn Over), [meaning cycle per liter of nickel plating bath will be all out to fix added nickel when opening cylinder called a loop, a loop can be deposited coating least 900dm2 · μm]; maximum deposition rate of up to 20-25μm / h; bath loading capacity, can accommodate up to 15 square decimeter per liter stable performance and long-term work and bath throwing ability, throwing ability; hardness, corrosion resistance strong; coating low porosity, 15μm pore-free; wear resistance, better than chrome plating; good weldability, can The wetted by the solder; electromagnetic shielding performance, and can be used for electronic components and computer hard disk; acidic electroless nickel phosphorus plating performance :6-9% (wt); resistance :60-75μΩ · cm; Density: 7.9g / cm3; Melting point :860-880 ℃; Hardness: Plated: Hv 500-550 (45-48RCH); binding force: 400MPa much higher than the plating; heat treatment: Hv1000; internal stress: a steel stress less than 7MPa acidic The use of electroless nickel plating products using internationally accepted A, B, C three solutions to A, B open cylinder, according to the concentration of nickel ions for analysis of additional components of the working fluid consumption to A, C additional, extremely Convenience: Acidic nickel cylinder open method preparation example 1 liters working solution NICHEM 2008A 6% 60ml NICHEM 2008B 15% 150ml residual amount of deionized water (conductivity of less than 5μs/cm) and aqueous ammonia (pH adjustment 4.6- 4.8) Temperature :85-90 ℃ loading capacity :0.5-15dm2 / L the specific method, the first volume is calculated and the scale in the tank mural, half filled with deionized water volume, then add 6% and 15% A B, deionized water is added to the mark a little below, and then ammonia to adjust the pH value to the mark, then heated to 88 ℃ plating according to process requirements. Acidic electroless nickel plating bath of the working fluid and additional Ni2 + standard concentration of 6.0 g / l, Ni2 + concentration methods: 5ml pipette with the working fluid into 250ml conical flask, add 50ml of deionized water, then add 10ml of ammonia (28%), shake, add 0.2 g Murexide indicator, shake, with standard solution of 0.05M EDTA titration, the end is light brown to pale purple. Whichever amount is calculated by EDTA is calculated as: A quantity additional additional amount of C = (ml) = (6-EDTA dosage × 0.59) × 10 × volume (L) operating points acidic electroless nickel plating bath to ensure the use of before nitric acid (1:1) soak and rinse the bath temperature was maintained at 85-90 ℃, temperature is too low, the speed is slow, then the bath temperature is too high with the decomposition of ammonia and sulfuric acid (20%) adjusted to pH , keeping the pH at 4.6-4.8, the deposition rate in order to ensure, pH, slow deposition rate is too low, too high, the decomposition bath, preferably with a pH meter control. Avoid introducing heavy metal impurities and surfactant |
