由于有机硅类消泡剂表面活性强，热稳定性好，消泡能力强，Si—C链和Si

Since the silicone-based defoamer strong surface activity, good thermal stability, defoaming capability, Si-C and Si-O chain chain binding stability, chemical stability, a silicone-based defoamer study abroad than many. Cheng Huang silicon paste and polyether modified silicone oil and a hydrophobic fumed silica made simethicone as a main component, Span-60, Twen-60 as emulsifier to prepare an emulsion type silicone defoamer efficiency . Silicone antifoam defoamer preparation, preferably defoaming performance and stability, a wide range of applications.

Because of the strong surface activity of silicone defoaming agent, good thermal stability, strong defoaming ability, Si-C chain and Si-O chain combined stable, good chemical stability, more research on silicone defoaming agent at home and abroad. Huang Cheng and other silicon paste and polyether modified silicon oil made of hydrophobic gas-phase silicon dioxide and dimethyl silicon oil as the main components, Span-60, Twen-60 as emulsifiers, the preparation of high-efficiency emulsion-type silicone defoaming agent. The foaming, defoaming performance and stability of the prepared silicone defoaming agent are good, and the application range is wide.

Due to the strong surface activity, good thermal stability, strong defoaming ability, stable combination of Si-C chain and Si-O chain, and good chemical stability, organosilicon defoamers have been studied more at home and abroad. The silicone paste and polyether modified silicone oil made from hydrophobic gaseous silica and two methyl silicone oil are the main components of Huang Cheng et al. Span-60 and Twen-60 are used as emulsifiers to prepare high performance emulsion type organosilicon defoamer. The antifoaming and antifoaming properties and stability of the prepared organosilicon antifoaming agent are good, and its application range is wide.<br>
