1. Toxicity and pollution levels differences in chemical drum accessories
Trivalent: the price of trivalent chromium is higher, but the toxicity is low, only 1% of hexavalent chromium and the passivation effect is also good.
It can meet the requirement of 72-hour salt spray white rust less than 5%, the harm of chromium 3 is small, and the pollution degree of chromium 3 plating is reduced.
Hexavalent: Hexavalent chromium passivation process has many advantages, such as high corrosion resistance, self-healing ability of self-repair corrosion resistance, can easily passivation out of silver, blue and white, colorful, military green, black and other colors, raw material sources are wide and cheap.
However, hexavalent chromium is a carcinogen and has serious harm to the environment and human health.
