    Mr. Lin's company is the owner of an acid galvanizing plant in Wuxi, Jiangsu.Recently, the screw fittings produced by Mr. Lin will always turn black at the thread position after galvanizing, and the problem has not been solved after the plating solution treatment.So Mr. Lin asked the supplier to solve the problem of the plating solution as much as possible, while looking for an acid galvanizing additive that is not easy to blacken.

    One day, Mr. Lin found Bigolly Technology by searching the Internet for "acid galvanizing additive manufacturer", and consulted related acid galvanizing additives.After understanding Mr. Lin's problems in detail, Bigolly's engineer recommended Mr. Lin to use this galvanizing additive BZ-528.He also explained to Mr. Lin that our acid zinc plating solution will accumulate iron impurities in the plating solution due to the poor washing of the pickling solution or the drop of the workpiece during the production process.However, some galvanizing additives on the market have poor resistance to iron impurities, and the galvanized layer is prone to blackening.

    And this acid galvanizing additive BZ-528 has good resistance to iron impurities, even if the iron impurity content in the plating solution is 80ppm, the coating of the workpiece will not appear black;Moreover, this galvanizing additive has few decomposition products in the production process and high stability of the plating solution, so that the consumption of the additive is low, and the production cost can be effectively saved.So Mr. Lin decided to buy 2 barrels of acid galvanizing additive BZ-528 to try.


    Mr. Lin opened a small slot and used this galvanizing additive BZ-528 for continuous production for half a month, and the workpiece did not appear black;The galvanizing additive used before will turn black in less than a week after the new groove is used.In contrast, the acid zinc additive BZ-528 has good impurity resistance, high bath stability, and the use of zinc additive is 20% lower than before.week after the new groove is used.In contrast, the acid galvanizing additive BZ-528 has good impurity resistance, High stability of plating solution, and the use of zinc additive is 20% lower than before.Therefore, Mr. Lin and Bigolly formulated a long-term cooperation purchase and sales contract.

    Therefore, in the production process of acid galvanizing, the coating of the workpiece is prone to blackening. You may try this acid galvanizing additive BZ-528 from Bigolly.If you are also looking for an acid galvanizing additive with good resistance to iron impurities,you may contact Bigolly customer service to obtain free samples and detailed technical information!
