乳化剂对柴油微乳液粘度的影响

Influences of the Emulsifiers on Viscosity of Diesel Oil Micro-emulsion

实验比较了不同乳化剂复配体系加溶水量大小,并研究了在相同乳化剂复配时不同加入量对柴油微乳液粘度的影响。结果表明,离子表面活性剂在总表面活性剂中含量较高时加溶水量较高,三组分乳化剂复配较两组分复配加溶水量高;无论是用何类型的乳化剂组合的两组分或三组分复配乳化剂,随着乳化剂含量的增加,微乳液粘度均增加,但三组分乳化剂复配制备出的柴油微乳液粘度增加趋势较两组分平缓。

The water solubilization in the different emulsifiers compounded system is compared, and the effect of the amount of the same compounded emulsifier on the viscosity of micro-emulsion is researched. The experiment results show that water amount of solubilization is high in the micro-emulsified diesel oil when the percentage content of ionic surfactant is high in the total surfactant amount. Compared with the utilization of two emulsifiers, the water amount of solubilization is higher when three emulsifiers are mixed into the micro-emulsified diesel oil. The viscosities of micro-emulsified diesel oils all increase with the increasing of the percentage content of emulsifiers, whatever kind of emulsifiers are compounded. The increasing trend of viscosity is much flatter when three emulsifiers are compounded.
