摘要
本文除传统的界面张力影响之外,经分析分别引入界面粘度和分散相粘度的影响,推导建立了预测内相分散水滴和乳状液分散液滴体积表面积平均直径的数学模型.建立的两个模型和实验数据吻合良好.
The size distribution of dispersed droplets in W/O and (W/O)/W systems
prepared in a standard stirred tank was measured by an Automatic Particle
Analyzer and microphotography incorporated with an IBAS Image Analysis
. system. Different emulsions were prepared at various stirrer speeds with two
kinds of surfactants for the study.
Mathematical models for estimating Sauter mean diameters of droplets for W/O and(W/O)/W dispersion systems, dp32 and d32, were developed respectively as equations (12) and (22), other than the effects of geometric parameter of vessel Dt, the operational parameter Nr and the properties of liquids usually considered, the effects of interfacial viscosity and emulsion viscosity were included in the equations. The equations fitted the experimental data quite well.
