Some customers have asked how we should maintain the tank solution when using potassium chloride galvanizing brightener. We have summarized 10 useful measures based on our years of experience in door-to-door service, and we will start with 5 of them in this article.

Use and maintenance of galvanizing bath solution

①The bath is related to the season. When potassium chloride galvanizing is carried out in winter, the mass concentration of zinc chloride in the plating solution should be taken as the upper limit, and if it is summer, then the mass concentration of zinc chloride should be taken as the lower limit.

② When the anode zinc plate is normally dissolved, the plate should show white crystalline organization.

③We can make adjustments to the usual mass concentration of zinc ions by increasing or decreasing the number of zinc anode plates. In order to maintain the stability of zinc ions, we must maintain the cathode-anode area ratio, and control the anode area to be 1.5-2.0 times of the cathode area.

④ The mass ratio of potassium chloride to zinc chloride should be maintained at (2.5~3.0):1.0.

⑤ Ensure the quality concentration of boric acid in the plating solution to ensure the pH value of the plating solution. We have found that if the quality concentration of boric acid is low when performing potassium chloride roll-on galvanizing, it is easy to cause roll-on barrel eyes to appear.

Conclusion

When plating plants use Bigely potassium chloride zinc plating brightener, we will arrange for a technical engineer to advise it on how to maintain the bath, in which case it will be able to ensure that the bath is stable and produce a galvanized layer with fine crystallization and good alignment.
