Chromium fog inhibitor is prepared with intechem series fluorocarbon surfactants. It has good inhibitory effect on chromium acid fog, and has excellent characteristics such as strong acid resistance, high temperature resistance, strong oxidant resistance and so on. Chromium plating usually takes high concentration chromic acid solution (CrO3 250G / L, h2so42.5g / L) as chromium plating solution. The cathode current efficiency of chromium plating solution is very poor (10% ~ 15%). The anode uses insoluble lead electrode, which rapidly produces hydrogen and oxygen at the two poles, which is easy to form a large number of harmful chromium fog to escape.

1. This product is mainly used for chromium fog suppression of electroplating solution in fluoroboric acid plant. It can effectively inhibit the escape of chromium fog, eliminate the exhaust device and chromium fog recovery device, and protect the health of operators. 2. In addition, it can also be used as a fog inhibitor for other acid and alkaline plating cells or electrolytic cells.

3. The deep plating capacity of low chromium process is doubled and the dispersion capacity is increased by 30-60%.

4. The content of chromium mist in the air can be reduced to 0.005-0.002mg/m3, which is lower than the national standard of 0.05g/m3.

5. The current efficiency of low chromium process is increased by 60-110%, and the current efficiency is generally 20-30%.

6. The neutral salt spray test is improved by 2-3 levels, with good corrosion resistance.

7. HV hardness increases by 30-60%, generally in hv1000-1260.

8. The chromic acid is saved by 60-85%, and the wear resistance of chromium layer is improved by 2-3 times.

9. Save electricity and energy by 60-85%, and double the service life of rectifier power supply equipment.

10. The concentration of chromium wastewater is only 10-20% of that of high chromium, saving more than 65% of the treatment cost.

11. There is no corrosion in the electroplating area, no radioactive pollution, and the accumulation rate of heavy metal impurities is low.

12, add this product should not be too much, that is, the foam thickness should not exceed 3cm. The electrode contact of the plated part is good. Prevent sparks and maintain air circulation to avoid hydrogen accumulation and explosion.

Usage and dosage

Add the chromium mist inhibitor into the electroplating bath, and add about 0.05 ~ 0.12 g (0.04 ~ 0.1 ml) of this product per liter of electrolyte. However, it needs to be added more in use, which can be added one by one according to the consumption in the future. Consumption: Kah / 6 G.
