1·Cationics are usually quaternary ammonium salts.
阳离子表面活性剂通常为季铵盐类。
2·Oil displacement mechanism of quaternary cationics has been studied in several ways: surface and interface tension, wettability, surface electrical behavior.
研究了季铵盐型表面活性剂的驱油机理：表面张力和界面张力、表面润湿性、表面电性。
3·TOYO LAB-35 is amphoteric surfactant. It is readily compatible with cationics, anionics and nonionics surfactants. Many these preparations results clear liquid or gels.
是一种两性表面活性剂，它可与阴离子表面活性剂、阳离子表面活性剂和非离子表面活性剂相容，相容后可生产清澄的液体或胶体。
