Some customers have asked that when we use potassium chloride galvanizing brightener with malfunction, we need to do Hall tank test to troubleshoot, what principles do we need to follow in order to take less detours and solve the malfunction problem at lower cost? Regarding this issue, we have summarized 2 principles based on years of experience in door-to-door service, as long as we do these 2 points, it will be conducive to the electroplating plant to quickly troubleshoot the cause, and then the right remedy.
In the Hull bath test, whether it is the process conditions or the plating solution components, only one factor can be changed at a time, and not two or more factors at the same time, otherwise it is impossible to determine which factor change is at work.
We give an example, in the use of potassium chloride zinc plating brightening agent production, if the plating layer burnt area is too wide, at this time to do the Hall tank test to determine, if both lowering the plating solution pH and at the same time replenish the main salt of zinc chloride, it is not right.
If the pH of the plating solution is too high, the plating plant technician should first lower the pH to a normal value and try it once. pH is normal and if the burnt area is still wide, then you should add boric acid and try it once. If it is still not possible, only then can we consider adding zinc chloride.
