研究了阴/阴离子型、阴/非离子型、阴/阳离子型、阴/两性型表面活性剂复合体系的泡沫性能与降低表面张力增效协同性能。结果表明:复合体系均体现了一定程度的协同性能,但阴/阳离子型、阴/两性型表面活性剂复合体系的增效协同性能更好。SDS/OB-2复合体系中,当m(SDS)∶m(OB-2)=1∶2~1∶4时,复合体系最大起泡高度达245mm,表面张力降至23.2mN.m-1;SDS/BS-12复合体系中,当m(SDS)∶m(BS-12)=1∶3~1∶6时,复合体系最大起泡高度达244mm,表面张力降至24.4mN.m-1左右,复合体系具有超起泡能力,均体现出优异的增效协同性能。
The synergistic properties of foam properties and surface tension synergism of anionic / anionic, anionic / nonionic, anionic / cationic and anionic / amphoteric surfactant systems were studied. The results showed that the synergistic properties of the composite systems were all exhibited. However, the synergistic synergistic effects of the anionic / cationic and anionic / amphoteric surfactant systems were better. SDS / OB-2 composite system, the maximum foaming height of the composites reached 245mm and the surface tension decreased to 23.2mN · m -1 when m (SDS): m (OB-2) = 1: (SDS): BS (BS-12) = 1: 3 ~ 1: 6, the maximum foaming height of the composites reached 244mm and the surface tension decreased to 24.4mN.m- 1 or so, the composite system with super-blistering ability, both show excellent synergistic synergistic performance.
