硅氟两亲聚合物在柴油/水体系中的分水效能及机理
Water separation performance and mechanism of fluoro-silicone amphiphilic polymers in diesel oil-water emulsion system
摘要
Abstract
Water separation efficacy of diesel oil -water emulsion system of four kinds of fluoro -silicone polymer with different degree of polymerization of the fluorinated chain was evaluated,and the mechanism for such phenomena was studied via interfacial tension and interfacial viscoelasticity measurements. Results show that,following the increase of degree of polymerization of the fluorinated chain,time needed for diesel oil-water separation decreases firstly and then increases. In case the degree of polymerization of the fluorinated chain achieves 16 and the mass concentration of fluoro - silicone polymer achieves 0. 2 g/L, complete separation of diesel oil and water can be performed within 23 s. Interfacial tension is not the main factor affecting the water separation efficacy. Effective water separation of this kind of polymer is mainly caused by reduction of viscoelasticity of the interfacial film.关键词
