摘要: 用马尔文MastersizerMicroplus型激光粒度仪对液体石蜡及环氧树脂E-20与甲苯等有机溶剂以不同比例所形成的体系经乳化后的粒子大小及分布进行研究,结果表明,随着油溶性表面活性剂在油相中溶解性的改善,分散相的粒子大小及分布也明显得到改善.cmcO及cmcW的协同作用对获得理想的分散相粒子大小及分布起到了至关重要的作用

Abstract: The diameter and distribution of particles in the emulsion were investigated by means of the Mastersizer Microplus of Malvern. The results showed that with the addition of solvents such as toluene, trichloromethane etc., solubility of the surfactants in the oil phase was getting better, the diameter and distribution of the particles in the emulsion were becoming small and narrow. It is proposed that the united effect of cmco and cmcw is the key factor influencing the process of emulsification.
