    Mr. Zhu is the owner of a home appliance plating factory in Suzhou, Jiangsu Province, with 2 copper plating production lines.Recently, in the process of using acid copper plating brightener, the brightness of the workpiece coating is poor, and the low area is seriously fogged.After the operator treated the plating solution, the brightness of the workpiece coating was still very poor.So Mr. Zhu quickly turned to Bigolly's engineers to help solve the problem.

    After the engineer rushed to the site, according to the site experience and the characteristics of the product acid copper plating brightener Cu-510, the production of the production line and the treatment of the plating solution by the operator found that the effect was still not good after the operator added sulfuric acid, copper sulfate and chloride ions to adjust the plating solution. After adding hydrogen peroxide and activated carbon, the plating solution was filtered, but no heating treatment was done, resulting in poor brightness of the coating.

    The engineer took the plating solution for Hull cell filming, and found that the brightness of the coating leveling was poor and foggy.Then add a small amount of hydrogen peroxide and activated carbon to the plating solution to filter it clean, then heat the plating solution to above 70 ℃ and electrolyze it for 4 hours.Wait until the plating layer is electrolytic evenly, stop electrolysis, and add brightener according to the normal proportion, and the plating layer will restore the effect of leveling the mirror brightness.So the engineer assisted Mr. Zhu in treating the plating bath in the same way. After more than ten hours of adjustment, the plating bath resumed production.

    The engineer sent Mr. Zhu and the operator for training.In the production process, when the proportion of acid copper brightener is out of balance and difficult to adjust, especially in the case of excessive cylinder opening agent Cu-510Mu and excessive brightener Cu-510B, hydrogen peroxide and activated carbon can be added appropriately to treat the plating solution.After that, the bath needs to be heated to remove the residual hydrogen peroxide, otherwise the bath imbalance will be more serious.

    Therefore, in the process of using acid copper plating brightener, when the brightness of the workpiece coating is poor and foggy, it is critical to properly handle the plating solution.If you are interested in acid copper plating brightener, please contact Bigolly customer service for free samples and detailed technical information!
