What impact do organic impurities in the nickel plating solution have on the plating layer, and how to remove them?
High content of organic impurities will lead to problems such as poor color, poor bonding strength, and easy scorching of the coating. There is no good way to remove it. Some people recommend using a concealer, but it can only cover it for a while. It still needs serious treatment. Treat it with hydrogen peroxide and activated carbon. A large part of the reason for the sudden increase in organic impurities in the plating solution may be due to current problems that cause the brightener to decompose rapidly. So it is necessary to check the power supply~~~~~~~

If the nickel plating solution contains organic impurities, it will seriously affect the quality of the coating, make the nickel layer brittle and fall off, and cause pitting in the coating. Organic impurities are usually removed by adsorption with activated carbon, and the dosage is about 2 to 5 grams/liter. It can also be treated with electricity, heating the plating solution to 50 to 60°C, stirring vigorously, using waste parts as cathodes, and processing at low current density for 4 to 6 hours.

It will make the nickel layer brittle and fall off, and it will also cause pitting in the coating. Organic impurities are often adsorbed and removed with activated carbon, and the dosage is about 2 to 5 grams/liter. Stir vigorously for about an hour, let it sit and then filter. In addition, it can also be treated with electricity, heating the plating solution to 50 to 60°C, stirring vigorously, using waste parts as cathodes, and processing at low current density for 4 to 6 hours. This method is simpler, but the effect is not as good as activated carbon adsorption.
