一种新型的制乳技术──膜法制乳

A New Emulsion Process - Membrane Emulsification

乳液在工业中有着广泛的应用，传统的制备乳液的方法多种多样，但主要采用的方法是机械搅拌或高压分散，这种方法能耗大，制乳效果差，制得的乳液液滴不均匀。膜法制乳的方法是靠膜两侧的压差使分散相以微小液滴的形式通过微孔膜，并分散在连续相中，从而形成乳状液。这种方法所需压力很小，形成的液滴直径均一，并能形成不同粒径的乳液，是理想的制乳方法。膜法制乳受膜材料、膜孔径、压差和表面活性剂等因素的影响。

Emulsion processes have been widely applied in many industrial fields. There are many kinds of traditional methods to prepare emulsion. In these methods mechanical agitation or high pressure are usually used, which cost too much energy and can' t get uniform liquid droplets Membrane emulsification is one of the best methods to prepare emulsion. In the process, the dispersed liquid droplets Permeate through the micropore membrane and distribute in continuous Phase under the action of the pressure difference between the two sides of the membrane.
