乳液乃是一种多相体系,其中有一种液体以液珠形式均匀地分散于一个不和它相混合的液体之中。对有机硅氧烷(即硅油)乳液而言,就是硅氧烷以液珠形式(也称分散相)分散于水(连续相)中。在有机硅氧烷乳液的制备和应用过程中,一个极其重要的问题就是乳液的稳定性。研究乳液稳定性的方法很多,但是稳定性在很大程度上取决于硅油分散情况,硅油分散得愈细、愈均匀,即硅油粒子愈小,粒径分布愈
Emulsion is a heterogeneous system in which a liquid is uniformly dispersed as droplets in a liquid that is not mixed with it. For organosiloxane (ie silicone oil) emulsions, the siloxane is dispersed in water (continuous phase) in the form of droplets (also called dispersed phases). One of the most important issues in the preparation and application of organosiloxane emulsions is the stability of the emulsion. There are many ways to study the stability of the emulsion, but the stability depends largely on the dispersion of the silicone oil, the more finely dispersed silicone oil, the more uniform, that is, the smaller the silicone oil particles, the particle size distribution more
