全氟壬基苯磺酸钠与碳氢表面活性剂复配体系研究

STUDY ON THE MIXED FS AND HYDROCARBON SURFACTANTS

研究了全氟壬基苯磺酸钠(FS)与不同离子类型的碳氢表面活性剂所形成的复配体系,结果表明,复配体系具有较强的增效作用,水溶液浓度为0.03%时,表面张力可降至30mN.m-1以下.其中FS/OP-10复配体系增效作用最显著,在FS/OP-10=1:3(质量比)时,表面张力降至20mN.m-1以下,并具有较低的界面张力.

The interactions between hydrocarbon surfactants and perfluorosulfonate were investigated through the measurements of surface tension. The result shows that the surface tension with 0.03 % of mixed surfactants was reduced to the range of 18 ～30 mN· m^-1. For the mixed surfactant of FS/OP - 10, the surface active nature will be intensely beneficiated . When the mass ratio of FS/OP - 10 was 1 ： 3, the system was high temperature tolerant , salt tolerant and low interfacial tension.
