| 摘 要： | 利用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的接触角,用荧光猝灭法测定了SDBS在水溶液里的胶束平均聚集数。并由此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。

| Abstract: | The wettability of the solid powders (silica gel or kaolin) were measured with Washburn equation expressed as contact angles. The contact angle changes for SDBS(Sodium Dodecyl Benzene Sulfonate) aqueous solutions on a silica gel or kaolin powder were studied. The average aggregation number of micelle in SDBS aqueous solution was measured with fluorescence quenching method. The relationship among the wettability of the powder, the critical micelle concentration (CMC) of SDBS and the mimic oil recovery of the resident oil on the powder was explored.$$$$ |
