Mr. Feng's tin-plated workpieces were always complained by customers that the coating of the workpieces changed color or darkened within 3 minutes of high-temperature soldering, which seriously affected the functional application of the workpieces.In order to retain these customers, Mr. Feng urgently wants to replace a matte tin plating additive that will not change color.
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.
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.
