中文摘要:
      为揭示不同结构表面活性剂制备的绒囊流体性能特征,分别采用十二烷基硫酸钠(SDS)、十二烷基苯磺酸 钠(SDBS)、烷基酚聚氧乙烯醚(OP-10)、十六烷基三甲基溴化铵(CTAB)和改性多糖制备了系列绒囊流体,研究 了所得绒囊流体的流变性能,考察了温度、NaCl和盐酸对绒囊流体流变性能的影响。结果表明,采用不同表面活 性剂制备的绒囊流体流变性能有较大差异。用SDS制备的绒囊流体表观黏度最大,CTAB的次之,再次的是SDBS,OP-10制备的绒囊流体表观黏度最低。绒囊流体的黏度与温度呈现独特的变化关系:在温度较低时,黏度随 温度的升高而降低;当温度达到约80℃时,黏度随温度升高而降低的趋势变缓;当温度升至约100℃时,黏度不再 随温度升高发生明显变化。当温度高于120℃时,SDS、OP-10和CTAB制备的绒囊流体的黏度值相当,SDBS的 黏度最小。绒囊流体在140℃高温下的黏度稳定性按所用表面活性剂排序如下:OP-10>CTAB>SDS>SDBS。 以SDS、SDBS、OP-10和CTAB制备的绒囊流体加入2% NaCl后的表观黏度变化率均小于10%,具有良好的耐盐 性能。绒囊流体的耐酸性按所用表面活性剂排序如下:CTAB>OP-10>SDS、SDBS。制备耐酸性绒囊流体应选 用阳离子表面活性剂,采用阴离子表面活性剂SDS、SDBS不能制备出耐酸性能良好的绒囊流体。图1表9参13
英文摘要:
      In order to reveal the properties of chorionic vesicle fluids prepared by different surfactants,a series of chorionic vesicle fluids were prepared by using sodium dodecyl sulfate (SDS),sodium dodecylbenzene sulfonate (SDBS),alkylphenol polyoxyethylene ether (OP-10),cetyltrimethylammonium bromide (CTAB) and modified polysaccharides. The effects of temperature,NaCl and hydrochloric acid on the rheological properties of chorionic vesicle fluids were investigated. The results showed that the properties of chorionic vesicle fluids prepared by different surfactants were significantly different. The apparent viscosity of chorionic vesicle fluid prepared by SDS was the highest,followed by CTAB,SDBS and OP-10. The viscosity of chorionic vesicle fluids showed unique change relationships with temperature. When the temperature was low,the viscosity decreased with increasing temperature. When the temperature reached about 80℃,the decrease of viscosity slowed down with increasing temperature. When the temperature rose to 100℃,the viscosity no longer changed. When the temperature was higher than 120℃,the viscosity of chorionic vesicle fluids prepared by SDS,OP-10 and CTAB was comparable,while that by SDBS was the lowest. Four surfactants were arranged according to the viscosity stability of chorionic vesicle fluid at 140℃ in following order: OP-10>CTAB>SDS>SDBS. The change rates of the apparent viscosity were less than 10% after adding 2% NaCl into the chorionic vesicle fluids prepared by SDS,SDBS,OP-10 and CTAB,which had good salt resistance. Four surfactants were arranged according to the acid resistance of chorionic vesicle fluid in following order:CTAB>OP-10>SDS≈SDBS. In general,cationic surfactant should be used to prepare acid resistant fluids and anionic surfactant such as SDS or SDBS could not be used.
