摘要
针对二元复合体系黏度及界面张力稳定性开展室内实验研究,实验结果表明:2 500万分子量聚合物和3 500万分子量聚合物,在前7天黏度均降低较快,15天之后体系黏度渐趋稳定,但是后者抗老化能力明显比前者强;体系界面张力值随时间变化呈现出先降低,然后再升高,逐渐平稳的趋势,15天之后体系界面张力渐趋稳定;老化时间和表活剂浓度一定时,聚合物浓度越高,体系黏度越大,体系的界面张力越大;当老化时间和聚合物浓度一定时,二元体系表面活性剂浓度增大黏度略微增大,界面张力值随表面活性剂浓度增加而降低。
Based on the viscosity and interfacial tension of binary composite system stability,the indoor experi-mental was carried out.The results show that,25million molecular weight of polymer and polymer molecular weight35million,the viscosity decreases rapidly in7days before and the system viscosity stability gradually in15days later,but the latter anti-aging ability significantly better than the former.The values of interfacial tension first step up,then step down and gradually smooth trends as the time increasing.When the aging time and surfactant concen-tration is a fixed value,polymer concentration is higher,the greater the viscosity,the greater the interfacial ten-sion.When the aging time and polymer concentration is a fixed value,surfactant concentration of binary system in-creases so that viscosity increased slightly,the interfacial tension decreased with increasing of surfactant concentra-tion.
