实验室考察了非离子表面活性剂ＯＲＳ对石油氧化皂（ＰＯＳ２）及其复配体系界面活性的影响。结果发现，在ＰＯＳ２与ＰＯＳ２／ＯＲＳ复配体系中加入ＯＰ类（ＯＰ７，ＯＰ１０，ＯＰ３０）和Ｔｗｅｅｎ类（Ｔｗｅｅｎ２０，Ｔｗｅｅｎ８０）非离子表面活性剂，不能改善体系的界面活性，反而使体系的界面活性变差。
The laboratory investigated the effect of nonionic surfactant ORS on the interfacial activity of POS 2 and its complex system. The results showed that adding OP (OP7, OP10, OP30) and Tween (Tween80) non-ionic surfactant to POS2 and POS2 / ORS complex system can not improve the interfacial activity of the system, Worse.
