摘要

制备了聚合物/表面活性剂二元乳状液,考察了聚合物相对分子质量、聚合物质量浓度、表面活性剂质量分数、油水比(原油与聚合物/表面活性剂二元乳状液体积比)对二元乳状液稳定性的影响。结果表明:提高表面活性剂的质量分数和聚合物的质量浓度,采用相对分子质量较低的聚合物,降低油水比,有利于二元乳状液的稳定。
        Binary emulsion of polymer /surfactant is prepared and the influences of polymer molecular weight,concentration of polymer,concentration of surfactant,ratio of oil and water( volume ratio of crude oil and binary emulsion) on the stability of binary emulsion are investigated. The results show that the stability of binary emulsion increases with the decrease of molecular weight of polymer, furthermore,it increases with the increase of the concentration of polymer and surfactant. It also indicates that large ratio of oil and water leads to stability of binary emulsion.
