利用改进的Washburn方程测量固体粉末的润湿性, 研究了十二烷基苯磺酸钠(SDBS)水溶液在硅胶及高岭土两种固体粉末表面上引起的润湿性变化, 用荧光猝灭法测定了SDBS在水溶液里的胶束平均聚集数. 探讨了十二烷基苯磺酸钠水溶液在固体粉末表面的润湿性, 表面活性剂的临界胶束浓度(CMC)与表面含油粉末脱油率的关系, 对在非超低界面张力条件下, 通过改变固/液界面润湿性提高原油采收率作了实验探讨.
The wettability of solid powders was measured by the improved Washburn equation. The wettability changes of the aqueous solution of sodium dodecylbenzenesulfonate (SDBS) on the surface of two solid powders of silica gel and kaolin were studied. Fluorescence quenching The average micelle concentration of SDBS in aqueous solution was discussed.The wettability of sodium dodecyl benzene sulfonate solution on the surface of solid powder, the critical micelle concentration (CMC) of surface active agent and the oil removal rate The relationship between the non-ultra-low interfacial tension conditions, by changing the wettability of the solid / liquid interface to improve oil recovery was experimentally explored.
