Applicable process: high speed rolling nickel plating

Product model: nb-44r brightener

NLD - 55 open cylinder agent

WA - 88 - a wetting agent

Manufacturer: ternenbau

Product packaging: 10kg/ drum;25 kg/barrel

Key words: rolling plating, dark bright



Nb-44r is a high - efficiency brightener for rolling nickel plating.The light speed is fast, the flatness is good, goes the position is good, the coating is bright, the light persistence is strong, the consumption is moderate.It is suitable for the workpiece without special bending and stamping after plating.Bath is stable and easy to maintain, high tolerance of acrobatics, easy to operate, easy to grasp, no decomposition of harmful substances.                          


Bath composition and dosage operating conditions

Nickel sulfate, 250-300 grams/liter temperature 25 to 40 ℃

Nickel chloride 45 to 50 grams/liter PH 4.5 4.8

Boric acid 45 to 55 grams/liter slot voltage 12 to 15 volts

NB - 44 r brightener, 0.4 to 0.8 ml/l filter needs continuous filtration

Ld -55 cylinder opener 12-15 ml/l

Wa-88a wetting agent 0.5-1.0 ml/l



Nb-44r kiloampere hour 200-300 ml

Ld -55 kpa hour 40-100 ml


Plating solution preparation

1. Pour two-thirds of the water into the substitute tank, heat to 60℃, add the required nickel sulfate and nickel chloride, and stir to completely dissolve them;                       

2. Add nickel carbonate or 4% sodium hydroxide solution and adjust PH value to 5.2;                         

3. Add 1-2 ml/l hydrogen peroxide, dilute with water and stir for several hours before adding.                     

4. Add 2-3 g/l of activated carbon, stir for several hours, and leave overnight.Using a filter pump, the plating solution is filtered into a clean plating bath;                        

5, clean the filter pump, and then fill with activated carbon 0.2 g/l, or add filter powder 0.2/ l;               

6. Add boric acid to the process range, stir to completely dissolve it, and add water to the operating water level.Add dilute sulfuric acid and adjust PH value to 3.6;             

7. Conduct continuous electrolysis with a wavy cathode at a low current density of 0.1-0.3 amperes/square decimeter for more than 10 hours, until the low color changes from dark to light gray;                

8. Adjust the PH value to the process range, refer to the plating liquid composition and use scale, and then add the gloss agent to the plating test.
