摘要
有机硅乳液型消泡剂的消泡效果与乳液中硅油的粒径有关，最佳粒径为１０～２０μｍ。可以不采用匀桨泵、胶体磨，高速搅拌器等国内外常用的机械乳化手段，而是通过选择适当的乳化剂、增稠剂和通常搅拌设备，完成了粒径的控制。
The results of a study of silicone emulsion defoamer showed the defoaming of silicone emulsion defoamer was re-lated to the particle size of the emulsion. The optimum size range was 10-20μm. The particle size was controlled bythe use of proper emulsifier,thickening agent and common stirring apparatus instead of colloid mill and high-speed stirrer.
