摘要

采用旋转黏度计分别测量了当乳化剂和分散相的质量分数变化时

柴油-甲醇-水三相乳化液以及柴油-水二相乳化液的黏度.实验发现

乳化剂和分散相的质量分数均对乳化液黏度有影响:当乳化剂的质量分数小于4.8%时

柴油-甲醇-水三相乳化液的黏度均大于柴油-水二相乳化液的黏度; 当乳化剂的质量分数大于4.8%时

若分散相质量分数小于20%

三相乳化液的黏度小于二相乳化液的黏度

若分散相质量分数大于20%

则三相乳化液的黏度大于二相乳化液的黏度

且随着分散相含量的增加

两者的黏度差也增大; 就柴油-甲醇-水三相乳化液而言

即使分散相的质量分数相同

若甲醇和水的比例不同

其黏度也有差异; 乳化剂含量对乳化液黏度的影响要小于分散相含量的影响.

Abstract

A rotating viscometer was used to measure the viscosity of the three-phase emulsion composed of diesel

methanol and water

and the two-phase emulsion composed of diesel and water

respectively. An experiment was conducted to investigate the influence of the mass fraction of the emulsifier and the dispersed phase on the emulsion viscosity. The results show that the viscosity of the three-phase emulsion is greater than that of the two-phase emulsion when the mass fraction of the emulsifier is less than 4.8%. If the mass fraction of the emulsifier is greater than 4.8% and the mass fraction of the dispersed phase is less than 20%

the viscosity of the three-phase emulsion is less than that of the two-phase emulsion. However

the viscosity of the three-phase emulsion is greater than that of the two-phase emulsion when the mass fraction of the dispersed phase is greater than 20%

and their difference increases with the increase in the mass fraction of the dispersed phase. For the three-phase emulsion

even if the mass fraction of the dispersed phase is same

the viscosity will vary with the different proportion of methanol to water. In addition

the influence of the emulsifier mass fraction on the emulsion viscosity is weaker than that of the dispersed phase mass fraction.
