We all know that sulfuric acid hydrochloric acid based tin plating brighteners have been widely used due to their high current efficiency, fast deposition speed, low electroplating cost, and easy treatment of wastewater.
A customer has reported that during the production process of using galvanized blue white passivation agent, the stability of the passivation solution is poor, and the workpiece is prone to yellowing and fogging after passivation. Additionally
In recent years, with the continuous increase in raw material prices, more and more people have stopped using imported acid copper brighteners and switched to cheaper domestic brighteners. However, there are a variety of acid copper brighteners available on the market, which brand is more effective?
In recent years, with the increasing quality requirements for galvanized workpieces, people have increasingly strict performance requirements for trivalent chromium blue white passivation agents for galvanizing. But many blue and white passivating agents on the market have defects such as uneven appearance color, easy yellowing and discoloration, and poor corrosion resistance. So how do we choose a more user-friendly trivalent chromium blue white passivating agent?
We all know that there are many colorful passivation solutions for zinc plating on the market, but many of them have defects such as unstable bath solution, short service life, uneven passivation appearance of workpieces, and poor corrosion resistance. So how do we choose a cost-effective trivalent chromium colorful passivation agent?
