摘要：研究阳离子表面活性剂十六烷基三甲基溴化铵(CTAB) 和驱油表面活性剂十二烷基苯磺酸钠(SDBS) 复配体系的乳化能力和表面张力等相关性能，并研究温度对复配体系的影响。实验结果显示，当阳离子表面活性剂和驱油表面活性剂复配体系的质量比为8:2时，表面张力低至29.92 mN·m-1，此时具有较强的表面活性，且温度的升高有利于表面张力的降低。实验结果还表明该表面活性剂复配体系对煤油的乳化能力较差，但CTAB和SDBS在乳化能力方面仍然存在增效作用。 关键词：表面活性剂；复配体系；表面张力；乳化能力 急，帮帮忙啦！ |

ABSTRACT: The combined system was composed by cationic surfactant of hexadecyl trimethyl ammonium bromide (CTAB) and surfactant for EOR of demulsifier dodecyl benzenesuifonate (DBSS) .The emulsify capability and surface tension properties were investigated . The influence of temperature to the system was also discussed. The result shows that the surface tension was declined to 29.92nN.m-1 and the system performed excellent surface activity when the mass ratio of CTAB and DTAB was 8:2 . The surface tension was decreased with the increase of temperature. In addition, this combined system shows poor the emulsify capability to kerosene, but improves the effect of that to CTAB and SDBS. Key words: surfactant; combined system; surface tension; emulsify capability 希望有帮助吧。等高手，虚心学习 |
