Detailed Product Description: | NICHEM 2010 full-bright nickel plating (phosphorus) 1 full-bright nickel plating characteristics: long cycle life, up to 8-10 cycles (Metal Turn Over), [meaning cycle per liter of nickel plating bath will be the fix applied to nickel when opening cylinder called a loop, a loop at least be deposited coating 900dm2 · μm]; maximum deposition rate of up to 20-22μm / h; throwing ability, throwing ability, fully meet "copying effect"; hardness, corrosion resistance strong; coating low porosity, 10μm pore-free; wear resistance, better than chrome plating; good weldability, can be wetted with solder; electromagnetic shielding performance, can be used for electronic components and computer hard disk; coating is amorphous, non-magnetic Ni-P alloy 2 full bright electroless nickel plating characteristics: phosphorus content :6-9% (wt); Resistivity :60-75μΩ · cm; Density :7.6-7 .9g/cm3; Melting point :860-880 ℃; Hardness: Plated: Hv 500-550 (45-48RCH); binding force: there is far higher than 400MPa steel plating; heat treatment: Hv1000; internal stress : steel stress less than 7MPa 3. full-bright nickel plating bath composition and operating conditions: raw materials and operating units range NICHEM 2010A% (v / v) 50 NICHEM 2010B% (v / v) 150 pH 4.6-4.8 Temperature ℃ 85-90 (87) loading dm2 / L 0.5-2.5 (1.5) hours depending on thickness depending on thickness 4 full-bright nickel plating solution preparation: open cylinder, with the solution in the tank by adding 1/2 of water. Add 5% A and 15% B, mechanical stirring, with a filter filtration. Add water to the desired approximate volume. Warmed to 88 ℃. With ammonia or sulfuric acid to adjust pH to 4.6-4.8 water to the mark to plating according to process requirements. 5 full bright nickel plating equipment needs projects require tank PP, PVC or high density PE. Linked with PP, PVC or 316 stainless steel. Ensure that the workpiece in the bath vertically adjacent two plates spaced minimum is 10mm. Primary and secondary air mixing tank should be moderate, cheer uniform mixing. Cycle 3-4 cycles per hour. Add system needs, feed pump made of PVC, PP or PE, can be resistant to alkali. Filtration system continuously loop filter with 10μm filter cotton core or filter bags. Ventilation needs. Heating system needs. Full-bright 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 to ionized 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) = (4.4-EDTA dosage × 0.29) × 10 × volume (L) can also check the following table the amount of additional EDTA ( ml) Ni2 + concentration (g / L) adding A volume ml / L of additional amount of C ml / L 15.17 4.4 0 0 15.06 4.36 2 2 14.95 4.33 4 4 14.84 4.3 6 6 14.73 4.27 8 8 14.62 4.24 10 10 14.51 4.21 12 12 full-bright nickel plating operation points should always measure the bath of Ni2 + content, temperature, PH value. Remained within the normal operating range not greater fluctuation. Plating tank material: stainless steel suitable, high-density polypropylene, a polypropylene liner acid resistant steel or other material; continuous anodic polarization necessary protection against spontaneous deposition. Filters: Recommended continuous filtration, bright coating requires continuous filtration 5um filter media, if the continuous filtration is not possible, the bath must be cooled at the end of the work, and then before the start of the next work cycle with 3um filter media. Even with continuous filtration, the plating tank, a heater and other equipment should be regularly with 30% dilute nitric acid stripping nickel layer, then rinse with water and then dilute potassium carbonate solution, dilute ammonia or deionized water. Mixing: the workpiece horizontally or clean oil-pressure air agitation, air agitation, the catheter can be decentralized polypropylene tubes with holes, pore size of about 2.5mm, with low pressure air (lateral opening blower). Heating: stainless steel or Teflon materials required: steam heating and electric heating can be. First passivation of stainless steel, and then to the anode protection to prevent precipitation of nickel stainless steel heater. Heating process should be properly mixed to avoid local overheating caused by plating bath turn slot. PH value adjustment: PH value by adding dilute ammonia to rise 50%, 10% sulfuric acid to reduce. Adjust the PH value should be appropriate while molting additional stirring bath. New bath PH value can be lower and lower temperatures (PH value: about 4.6, temperature: 86 ℃ or so), with the aging of the bath, PH value and temperature can be gradually increased, this will help get compared with the average deposition rate and phosphorus. To maintain optimum deposition rate and allow additional, bath Ni2 + content should not be less than 4.0g / L, recommended additional Ni2 + open cylinder should not exceed 15% of the amount, if the amount exceeds 15%, should be in every times the workload gradually supplemented, should be supplemented with the bath while stirring. Exhaust: To protect the health of workers and the proposed use. 8 full-bright nickel plating environmental protection and safety of persons and goods in order to avoid harm to the environment, access to product safety and environmental protection instructions manual is necessary. The company's product safety data sheet (MSDS) contains these instructions. 9 full-bright nickel plating warranty company for product quality to provide the effective legal guarantees within the scope of responsibility. Customers for products re-packaged product quality is not my company's warranty. In use, regardless of the user have any questions, our service technicians are ready to respond. 10 full-bright nickel plating and packaging NICHEM 2010A Product color is green alkaline liquid, plastic barrel. Packaging specifications for 25kg/pcs. NICHEM 2010B is a colorless alkaline liquid, plastic barrel. Packaging specifications for 25kg/pcs. NICHEM 2010C is a colorless alkaline liquid, plastic barrel. Packaging specifications for 25kg/pcs. |
