摘要
本文提出了表面活性剂在液膜膜相中有效浓度的概念并推导了其计算公式.通过大量实验和理论分析,探讨了乳化溶胀的产生机理,提出了界面湍动-乳化的机理模型,并据此导出了估算乳化溶胀率的数学模型.模型预测值和实验数据吻合很好.
The concept of effective concentration of surfactant in membrane phase, which considers the high adsorption density of the surfactant at the droplet interface in LSM system was proposed. The effective concentration of surfactant, Csef, could be estimated by equations(7)-(9). Swelling caused by emuls-ifioation during the initial dispersion process was investigated. Data of swelling ratio were measured by a density method. A general model for estimating the 'emulsification swelling' rate, Fse, was proposed on the basis of a mechanism of swelling due to the entrainment of water resulted from interfacial turbulence and emulsification in the initial dispersion process. Equation(26)gave excellent fit to experimental data of Fujinawa, et al. (1984, 1985) and the authors.
