【摘要】 研究了阴离子十二烷基硫酸钠、阳离子十六烷基三甲基溴化铵和非离子壬基酚聚氧乙烯醚等3种不同类型的表面活性剂对聚乙烯醇溶液黏度性质的影响。结果表明,离子型表面活性剂与聚乙烯醇发生疏水链相互作用使高聚物带有电荷,体系黏度增加;非离子表面活性剂与聚乙烯醇无相互作用,体系黏度不变;盐的加入,只对聚乙烯醇/离子型表面活性剂混合体系影响大,而对聚乙烯醇/非离子型表面活性剂混合体系无影响。更多还原

【Abstract】 Influence of different surfactants such as SDS,CTAB,OP-10,upon viscosity of polyvinyl alcohol(PVA) water solution is researched.The results show that the hydrophobically associating of ionic-surfactants and PVA improved the repelling forces of the charge,so the viscosity of water solution is increased,and that the lack of interaction of nonionic-surfactants and PVA,so the viscosity of water solution is not changed.Injecting the salts, the viscosity of PVA and ionic-surfactants mix water solution is changed much, and the viscosity of PVA and nonionic-surfactants mix water solution is not changed.更多还原
