Influence of SiO₂Particles on the Defoaming Performance of Silicone Oil Emulsion

Abstract:

The defoaming agent of silicone oil emulsion containing hydrophobic SiO₂ particles was prepared. The effect of different diameters of SiO₂ particles and amount of SiO₂ particles in the emulsion on the defoaming performance was studied, and the mechanism of defoaming was analyzed. The experimental results showed that when the amount of hydrophobic SiO₂ particles in the emulsion was 1%, the emulsion had good defoaming performance; The emulsion containing nanometer sized SiO₂ particles showed better defoaming performance than that of the emulsion containing micrometer sized SiO₂ particles.
