利用 Waring Blender 法研究了不同矿化度下两性离子表面活性剂十六烷基磺基甜菜碱(HDPS)与阴离子型表面活性剂十二烷基硫酸钠(SDS)单一体系和复配体系的起泡性能,分析了两性/阴离子型表面活性剂间相互作用对起泡性能的影响。结果表明,由于两性和阴离子型表面活性剂亲水基间的静电吸引作用既增强了复配体系的表面活性,又促进了复配体系在气液表面形成更加紧密的吸附膜,因而在清水和高矿化度水质中,HDPS/SDS复配体系的泡沫综合指数均高于单一表面活性剂体系,表现出协同增强泡沫性能的作用。

The foam properties of single and mixed surfactant systems prepared by zwitterionic surfactant N-hexadecyl-N,N-dimethyl-3-ammonio-1-propane sulfonate (HDPS)and anionic surfactant sodium dodecyl sulfate(SDS)were investigated by Waring Blender method.And the effect of intermolecular interaction between HDPS and SDS on the foam properties was analyzed.It has been found that the electrostatic attraction between the headgroups of HDPS and SDS not only reinforces the surface activity but also promotes the formation of compacted adsorption film in the gas-liquid surface for the mixed surfactant system.Therefore the foam comprehensive exponents of mixed HDPS and SDS surfactant systems are higher than that of each single surfactant in clean water and highly mineralized water,which exhibits the synergetic enhancement foaming properties.
