采用界面张力法和聚结电压法测定三种表面活性剂界面张力的时间效应、界面膜的聚结电压以及表面活性剂液膜体系的夹带溶胀率 .实验表明 ,吸附速度慢、聚结电压低的表面活性剂 ,其夹带溶胀小 .因此 ,认为抑制液膜溶胀的合适表面活性剂是一种吸附速度慢、聚结电压低的聚合物 . The interfacial tension of the three surfactants, the coalescence voltage of the interfacial film and the entrapping swelling rate of the surfactant liquid film system were measured by the interfacial tension method and the coalescence voltage method.The experimental results showed that the adsorption rate was slow and the coalescence voltage was low Surfactant with a small swelling of the entrapment It is therefore considered that a suitable surfactant which inhibits the swelling of the liquid film is a polymer which has a slow adsorption rate and a low coalescing voltage.
