微乳液体系相行为的一种表达——鱼形相图

An expression of phase behavior of microemulsion——fish-like diagram

对微乳液体系相行为的一种表达方式———鱼形相图的发展历程、绘制方式、相图特点及其计算进行了简要介绍。阐明了HLB温度、HLB平面等概念,对不同变量组合得到的鱼形相图进行归类并对其相关计算进行讨论。在介绍鱼形相图的同时,对一些影响微乳液相行为的因素如温度、表面活性剂组成等加以分析,得出其在影响微乳液相行为上具有的共同本质。介绍了利用Griffin的HLB值关联式求出实验条件下难以测定的表面活性剂的HLB温度的方法。

An expression for phase behavior of microemulsion,the fish-like diagram,of which the developing process,way of mapping and characteristics were briefly introduced here.Conceptions such as HLB temperature and HLB plane were described.Fish-like diagrams derived from different combinations of variables were categorized and discussed with respect to their concerning calculations.At the same time,some factors that influence the phase behavior of microemulsion,such as temperature and composition of surfactant etc.were studied and discussed with their common nature in influencing the phase behavior of microemulsion demonstrated.The method for using Griffin HLB correlation to obtain HLB temperature data,which is difficult to detemine under experimental conditions,was introduced as well.
