文摘After the careful analysis on the factors affecting the emulsification of the dispersion system consisting of oil, water and surfactant, and investigation on the mechanism for the formation of emulsions, a mathematical model to be used in the emulsification was derived finally. By comparing the results of experiments with the results concluded from the mathematical model, it was found that the model was reasonable and useful in the investigation of emulsifications.
