摘要
采用液滴注射法测量5种正烷烃(C6-C10)-表面活性剂-水制成乳状液的过热极限温度。结果表明,乳状液的过热极限温度随着表面活性剂含量增大而降低,含量大于某一数值后,过热极限温度趋于稳定。说明吸附在界面上的表面活性剂有利于沸腾核的形成。另外,随着乳化时的起始水油比例增大过热极限温度随之升高。
The superheat limit temperatures of n-alkane-surfactant-water emulsion systems have been measured by using the liquid column method.According to the data which have been measured,the superheat limit temperatures decrease with increasing concentration of surfactant and increase with increasing quantity of water.To explain such effects, the surfactant adsorbed on the interface accelerates the nucleation rate has been assumed.
