Chromium fog inhibitor
It is a newly developed environmentally friendly chromium fog inhibitor, mainly used in protective decorative chromium plating and hard chromium plating processes to inhibit the generation of chromium fog.
It is mainly used to replace the fluorine-containing chromium fog inhibitors still in use on the market, which contain PFOS chromium fog inhibitors are prohibited by the documents issued by the United Nations Environment Program and China Environmental Protection Administration.
1. Product properties
Appearance of white or yellow solid powder, fluorine free, non-toxic, harmless, non-corrosive, and does not burn, does not explode, the product is stable, clean, suitable for national environmental protection requirements.
Second, product performance
1, reduce the surface tension of the plating solution, good dispersion, so that the coating is more evenly spread.
2, the formation of continuous dense fine foam layer at the liquid level during electrolysis, can effectively prevent the overflow of chromium fog.
3, reduce the cost of electroplating, can reduce the chromium content in the air to 0.002-0.004mg/M3, lower than the national standard of 0.05mg/M3, but also save 30% of the use of chromium anhydride.
4, the current efficiency can generally be increased by 20-30%, low chromium process current efficiency can be increased by 60-80%.
5, HV hardness increased by 30-60%, strengthen the bonding force of chromium coating.
6, effectively reduce the corrosion of workshop instruments and equipment, can make the ventilation equipment long-term normal operation.
7, easy to use, low price, good stability.
8, eliminate the pollution of chromium fog to the environment, protect the health of workers, social and economic benefits are significant.
3. Usage and dosage
1, the calculated amount can be directly added to the plating bath, and then stir evenly.
2, the amount of use, according to 0.04-0.06g/L added.
3, in the electrolytic process, the white filter paper can be placed on the edge of the tank to check, when the filter paper is found to have small yellow spots, that is, it should be added by 0.02-0.04g/L. The number of refills may be 2-3 more times.
4, Suzhou Feihe products should be stored in the shade without light exposure, shelf life of 2 years.
