Mr. Zhou's company is a Shenzhen company engaged in the galvanized processing and production of nut workpieces.His nut workpieces are mainly used in automobiles, electronics and toys, so they need to have high performance requirements.Some time ago, due to the needs of customers, the workpiece needs a brighter galvanized layer, and the passivation film of the workpiece will appear peeling after color passivation.So Mr. Zhou wanted to replace a trivalent chromium color passivator that is not easy to release.
One day, Mr. Zhou saw Bigolly's trivalent chromium color passivator BZ-207 through an Internet search. After understanding the characteristics of this passivator in detail, he consulted the reason why the passivation film of the workpiece is easy to peel off.The engineer explained that because the galvanized layer is brighter, the binding force of the passivation film is relatively poor after using a general passivating agent. After the baking and aging process, the passivation film is easy to fall off, and the phenomenon of peeling occurs.Bigolly's trivalent chromium color passivator BZ-207 has good operability and can be applied to acid zinc and alkali zinc processes. Even if the zinc coating is brighter, the passivation film will not be released.
After thinking about it, Mr. Zhou thought he could give it a try, so he bought a small package of color passivator BZ-207.After 10 days of testing, Mr. Zhou used this color passivator BZ-207, the appearance of the nut workpiece was uniform and bright, and the passivation film of the workpiece did not appear to be peeled off;And several batches of workpieces can pass the neutral salt spray test for 150 hours, which is much better than the color passivator he used before.So, Mr. Zhou signed a cooperative purchase and sales contract with Bigolly Technology.
Therefore, in the process of color galvanizing of our nut workpiece, if the passive film of the workpiece is easy to peel off, you may try this trivalent chromium color passivator BZ-207 from Bigolly Technology, which can effectively solve the phenomenon of peeling of the passive film.If you are also looking for such a trivalent chromium color passivator,you may contact Bigolly customer service to obtain free samples and detailed technical information!
