表表面活活性剂浓浓度对对泡沫体体系稳稳定性的影响响

Effect of Surfactant Concentration on Foam System Stability

主要探探讨了在泡沫体体系内,表面活性剂对泡沫沫稳定性的影响响,以表活剂浓浓度为主要研究究点,总结了不不同表活剂浓度度下气泡的聚并并过程,还分析析了液膜的排液液过程,指出界界面流变学因素素以及表活剂高高浓度情况下的的胶束分层现象象是影响泡沫稳稳定的主要因素素。表活剂浓度低低于CMC时,界面流变学因因素起主要决定定作用;表活剂剂浓度高于CMC时,胶团分分层起主要决定定作用。

The effect of surfactant on foam system stability was discussed in this article. Thecoalescence process of bubbles under different surfactant concentration was analyzed as well as the foam drainage process. It＇s pointed out that interface rheological factorand micellar stratification under high surfactant concentration are main factors to affect the foam stability. When the concentration is below CMC,the interfacial rheological factoracts as an important role;when the concentration is higher than CMC,micellar stratification has obvious effect on the foam stablity.
