摘要

将乳状液通过填充介质层使分散相聚结进而得以分离的方法

是一种操作简便、费用较低、且分离效率较高的方法.本文研究了乳状液的分散相及连续相在填充介质表面上不同的润湿性能与聚结效率的关系

从热力学角度导出润湿功差的概念

以作为正确选择填充介质的重要判据.由测定的表面性质数据

计算了若干种纤维作为填充介质处理O/W(水包油型)乳状液的润湿功差

并实测了各纤维层中乳状液分散相聚结的效率.

Abstract

The separation of dispersions in emulsions by passing through a coalescing fibrous bed has many advantages over other types ot separation methods in its simplicity and efficiency. A thermodynamic term

the difference in the work of wetting

which characterizes the difference in fiber wettability by the continuous and dispersed phases is presented in this paper. It can be used as an important criterion for the correct selection of fibre media to obtain a high degree of coalesence. Furthermore

several kinds ot commercial fibres were investigated for treating oil in water emulsions. It was found that polypropylenc fiber had an excellent coalescence efficiency.
