摘要
以具有聚氧乙烯为亲水基团的非离子表面活性剂为主要乳化剂，其它表面活性剂每种类型各取一个与之复配，进行替换对比，从而以最少的表面活性剂种类，得到尽可能全面的乳液结构类型，以便找出乳液结构与乳化燃油燃烧热之间的关系。实验方法为，用超声波或加热的方法配制乳状液，用显微镜测定乳液结构，用氧弹法测定燃烧热，并进行燃油替换比较和乳液稳定性比较。
A series of emulsion fuel oil were designed with Triton X 100 as principal emulsifying agent,whose molecular formula is C 8H 17 ——O(CH 2CH 2O) 10 H.One of other kinds of surfactant is used as the auxiliary emulsifying agent.The emulsion structures were determined by micrography,and the combustion heat was determined by a bomb calorimeter.The relationship between the structure and combustion heat for the series of emulsion fuel oil was studied by the change of water content,the substitution of emulsifying agent and fuel oil.The experimental results can be explained by theoretical analysis from mixing enthalpy and evaporation heat of water.
