Introduction of defoamer in silicone

Defoamer (defoamer) is an auxiliary agent, whose function is to eliminate the foam formed by materials in the production process. The main component of silicone defoamer (silicone defoamer) is the silicone component in silicone oil. Silicone oil is an oily liquid, which is nonvolatile at room temperature, insoluble in water, animal and vegetable oil and mineral oil, or has little solubility and can withstand high and low temperatures. Inert in chemical properties, stable in physical properties and without biological activity. Silicone defoamer is a white viscous emulsion. It has been used in various industrial fields since 1960s, but its large-scale and all-round rapid development began in 1980s. As a defoamer in silicone, its application field is also very extensive, and it has attracted more and more attention from all walks of life. Silicone defoamer is an indispensable assistant in the production process of chemical industry, paper making, coating, food, textile, pharmaceutical and other industrial sectors. It can not only remove the foam on the surface of the process medium in the production process, but also improve the separation, gasification and drainage effects in the processes of filtration, washing, extraction, distillation, evaporation, dehydration and drying, and ensure the capacity of various materials and processing containers.
