Acid Potassium Chloride Zinc Electroplating Brightener

Once the potassium chloride galvanized solution is contaminated by hexavalent chromium, the source of the pollution should be found out first, and the source should be blocked first. The treatment method of hexavalent chromium is to use insurance powder, first reduce hexavalent chromium to trivalent chromium, and then adjust the PH value of the solution to about 6.0, precipitation and filtration. The effect of Nitrate is also a strong oxidizer, the brightener has a certain damage, generally nitrate ion should be less than 0.5g/L, a small amount of nitrate ion can be used for a long time electrolytic treatment of small current density, if the content is too high, can only replace the solution.

Description

The decomposition of additives and the accumulation of grease will produce organic impurities. If the content of organic impurities is too high, the coating will become dark or produce stripes, and the brittleness will increase. The coating will mist and not shine after passivation, and the covering ability will be reduced and the coating will be rough.

The treatment method is to increase the bath temperature to about 45℃, add 3g-5g/L activated carbon, stir for 30 minutes, stand filtration. After activated carbon treatment, the additive will also lose a part, must be appropriate to add, add the amount of hull slot to determine.
