chemicalsupplier antifoams silicon oil defoamer for wastewater treatment

Wastwater treatment silicone defoamer mainly achieves the purpose of eliminating foam by changing the interfacial tension of the foaming system. The general use concentration is 50-100ppm, and it has a good defoaming effect at a very low concentration. Compared with other defoamers, silicone defoamers have the following advantages: (1) The surface tension is low (21 mN/m), and the spreading rate is extremely fast; (2) The defoaming speed is fast, the foam suppression time is long, the efficiency is high, and the dosage is low. (3) Good dispersibility and small usage amount (50-100ppm), which can effectively reduce costs; (4) Good acid and alkali resistance, good chemical stability, and little impact on the system; (5) Good heat resistance and low decomposition rate at high temperature. (6) Professional defoamer manufacturers are self-produced and sold, with high quality and low price.
