When using alkaline galvanizing brightener in a plating plant, what is the best current density to control if you want to remove heterogeneous metal impurities by electrolysis?
In principle, in accordance with the plating impurities play an adverse effect on the current density range to determine. This is because a variety of impurity ions and metal ions to be plated reduction potential is different, some ions precipitation potential is more positive, mainly in the low current density area precipitation, some ions precipitation potential is more negative, mainly in the high current density area precipitation.
According to this principle, in the plating process using alkaline galvanizing brightener, if the influence of impurities is reflected in the low current density area, then the electrolytic treatment should be controlled at low current density, and if the influence of impurities is reflected in the high current density area, then the electrolytic treatment should be carried out at high current density.
If impurities affect both the high and low current density zones, then the plating solution can be treated with high current density electrolysis for a period of time and then switched to low current density electrolysis until the plating solution returns to normal.
