Recently, Mr. Zhang found in the production process that after the blue-zinc passivation of the workpiece, the coating always appears color deviation.However, this phenomenon still exists after the passivation solution is adjusted several times.So Mr. Zheng wanted to replace a trivalent chrome blue zinc passivator that would not deflect color.
Because Mr. Zhao's acid galvanizing bath is not equipped with a temperature control system, when the bath temperature is 28~32 ℃, the brightness of the coating is reduced, rough, and the adhesion is poor, and the amount of brightener is large, and the production cost is high.So Mr. Zhao wanted to find a potassium chloride zinc brightener with good temperature resistance.
Mr. Xu's accessories have been complained by customers about the poor brightness of the workpiece coating and the unstable performance test, which has seriously affected the service life of electronic accessories.However, after several adjustments of the plating solution, the coating brightness of the workpiece still cannot meet the customer's requirements, so Mr. Xu wanted to find a electroless nickel plating solution with good coating brightness.
In the process of galvanizing production, after color passivation of galvanized workpieces in some factories, the color of passivation film is always not red enough. What should we do? Try this color zinc passivator.
Many people think that it is better to use imported tin plating additives in the production process of tin plating.However, due to the high price of imported additives and the high production cost, we can actually consider choosing domestic sulfate tin plating additives with stable performance to try.
In the production process of using nickel plating brightener, sometimes the adhesion of the nickel plating layer is poor and easy to peel, which may not be a problem of the plating solution. It is also necessary to check the rectifier, because the failure of the rectifier will also affect the adhesion of the nickel plating layer.
