表面活性剂水溶液与油之间的动态界面张力研究

DYNAMIC INTERFACIAL TENSION IN SURFACTANT BRINE SOLUTION/ KEROSENE SYSTEMS

本文研究了两种表面活性剂(TRS10-80和天津ABS)盐水溶液与煤油之间的界面张力特性,提出了表面活性剂盐水溶液/煤油体系中动态界面张力产生的机理,讨论了表面活性剂对油的增溶作用对界面张力的影响。经过长期预平衡的表面活性剂盐水溶液/煤油体系仍然存在明显的功态界面张力特性。

<ABSTRACT>: The interfacial tension behavior between kerosene and two surfactant brine solutions(TRS10-80 and Tianjin ABS) was studied with the Spinning-Drop technigue in this paper.A mechanism for the formation of the dynamic interfa-cial tension in surfactant brine solution/kerosene systems was proposed. The effect of the solubilization of surfactants on the interfacial tension between oil and water was also discussed.The experiment data showed that the time depen-dence of inlerfacial tensions in the pre-equilibrated ( at least 10 days ) surf-actant brinesoluton/kerosene systems still exist.
