【摘要】 研究了水解聚丙烯酰胺、黄原胶和木质素磺酸盐对中相微乳液相体积、粘度和界面张力的影响．实验结果表明：含有聚丙烯酰胺时，中相微乳液的相态、增溶参数、中相与下相间界面张力及中相粘度均无明显变化．生物聚合物对中相微乳液的物理性质影响也不大．木质素磺酸盐则对微乳液的形成产生明显影响：随着木质素磺酸盐浓度的增大，微乳液由中相转变为上相，相应的物理参数亦有变化．更多还原

【Abstract】 The effects of partially hydrolyzed polyacrylamide(HPAM), xanthan gum(XC) and lignosulfonate(LS) on the middle phase microemulsion containing petroleum sulfonate, mixed n butyl and i propyl alcohols and mineralized water have been studied by phase volume, interfacial tension( IFT ), viscosity and solubilizing parameter measurements. Introducing polymers into the microemulsion caused slight increase of IFT , and no obvious change was observed in viscosity of middle phase. The volume of the middle phase microemulsion was decreased as the concentration of HPAM increased. Increase of LS led to disapearing of middle phase, forming Winsor 2 microemulsion system.更多还原
