The impact of impurities in chrome plating solution on the coating

Before entering the main text, there are 2 questions:
1. Is your chrome solution healthy?
2. Can the brightness, wear resistance, and corrosion resistance of the plated products meet customer requirements?
Whether your answer is 'YES' or 'NO', this article is worth reading!
The hard chrome plating market represented by gravure printing plates, piston rod plating, and mirror roller plating, despite many technological developments, the hexavalent chromium electroplating hard chrome process remains irreplaceable. However, due to the purity of raw materials and improper process flow, the plating solution cannot maintain a high purity level. As the usage time extends, the electroplating quality will gradually decline.
According to authoritative foreign literature, the impact of copper and iron impurities on chrome plating quality is significant. When the total content exceeds1.2g/Lthe wear resistance and corrosion resistance of the chrome layer will decrease; when the total content exceeds2.5g/Lthe brightness range and hardness of the chrome layer will be significantly affected, while the bath voltage increases and current efficiency decreases; when the total content exceeds5g/Lthe comprehensive indicators of the chrome layer can only reach half of that of a newly opened tank. When the impurity content of the electroplating solution exceeds the standard, especially in the summer when the temperature and humidity are relatively high, the comprehensive defects of the chrome layer are more likely to be exposed, leading to a significant increase in rework. Therefore, the maintenance of chrome solutions for many high-end products must be achieved through regular dilution to reduce the impurity ion content.
Rapid impurity removal equipment for chrome solution
Why is it the best solution? Maituo will only prove it with facts:
Patented product, no impurities with it, we care, you can rest assured~~
-
Tested by the market for many years, with solid technical indicators, many returning customers, and over a hundred units sold;
-
Used by dozens of domestic plate-making companies, as well as Japan's KYB company, which accounts for 40% of the global shock absorber capacity.
-
Usage cases1. A well-known domestic plate-making company, after impurity removal from the plating solution, the impurity content decreased. Through test samples, the dispersion ability of the plating layer was enhanced, and the brightness range of the plating layer was also expanded;

2. Japan's KYB company (8000L electroplating piston rod hard chrome solution)
