Electroplating nickel white mist fault treatment method mainly includes the following steps.
Deal with the impurities in the plating solution:
Remove the anode plate, add 5ml/L of decontaminant water (e.g. Bigelow's Ni-391 decontaminant water), heat to 60-70°C, and air stir for 2 hours. This step can be omitted if there is no reliable impurity remover.
When there are more organic impurities, add 3-5 ml/L of 30% hydrogen peroxide and air stir for 3 hours.
Add 2-5g/L of powdered activated carbon under constant stirring and continue stirring for 2 hours, then let stand for 4 hours, filter and clear the tank.
Electrolytic treatment:
Using a nickel-plated corrugated iron plate as the cathode, electrolysis was carried out at a current density of 0.5-1.0 amps/square decimeter until the surface of the plate turned grayish white. This process takes approximately 4-12 hours and may take longer with higher impurities. Air agitation must be turned on or the cathode moved during electrolysis to improve the treatment.
Adjust the composition of the plating solution:
Analyze and adjust the concentration of each component in the plating solution, performing a Hall tank test if necessary to ensure that the parameters are in the normal range.
If the saccharin content is too high, it may cause white haze on the nickel plating layer, so the saccharin content needs to be adjusted appropriately.
Sodium dodecyl sulfate content is too high will lead to white mist plating layer, can be reduced through electrolysis to reduce its content.
Measures to prevent white haze faults in nickel plating include:
Regular Hall tank test: This is an important means of detecting whether the plating solution is normal and effective.
Regular low-current electrolytic treatment: to remove impurities in the plating solution and prevent failures from occurring.
Regular analysis of the plating solution: to ensure that the main components of the plating solution are always maintained within the normal range.
Through the above steps and treatment methods, we can effectively solve and prevent the electroplating nickel white mist fault, to ensure the plating quality.
