摘要

本文介绍了多元乳化液内相液滴的结构和大小以及所产生的多元乳化液的流变特性。多元乳化液是在装有四个挡板的搅拌容器中产生的。研究中使用了两种不同的搅拌器：涡轮叶轮和 Rushton 涡轮叶轮。多元乳化液中使用的液体是：蒸馏水和精炼葵花籽油。8 克和 16 克大豆卵磷脂用作乳化剂。制备时间分别为 15 分钟和 45 分钟。用诊断倒置显微镜拍摄的照片展示了所得乳剂的结构。液滴的大小以液滴分布图的形式呈现。多重乳液的流变特性以图表形式呈现，并使用流变模型进行描述。

Evaluation of drops dimensions and rheological properties in production of multiple emulsion in a vessel

The structure and size of droplets of the inner phase of a multiple emulsion and rheological properties of the produced multiple emulsion are presented in this paper. The multiple emulsion was produced in a stirred vessel equipped with four baffles. In the study, two different stirrers: turbine impeller and Rushton turbine impeller were used. The liquids used in the produced multiple emulsion were: distilled water and refined sunflower oil. 8 g and 16 g lecithin from soya beans were used as an emulsifier. The preparation time was respectively 15 min. and 45 min. The structure of the obtained emulsions is presented in the form of photos taken with the diagnostic inverted microscope. The results size of droplets were presented in the form of graphics as a distribution of drops. The rheological properties of the multiple emulsion were presented graphically and it was described using the rheological model.
