Dilational rheological properties of polyacrylamide solutions at interfaces 驱油用聚丙烯酰胺溶液的界面扩张流变特征研究
Rheological property of the aqueous solution of branched partly hydrolyzed polyacrylamide 带支链的部分水解聚丙烯酰胺溶液的流变性
The paper has studied the effect of air on viscosity of pulp dissolved in cupriethy lenediamine solution 摘要研究了在测定漂白化学浆黏度过程中,溶解瓶中的空气对纸浆铜乙二胺溶液黏度的影响。
Results show that cellulose is degraded as a result of increasing the air in dissolving bottle and prolonging the time of pulp dissolving 结果表明,在纸浆溶解于铜乙二胺溶液过程中,溶解瓶中的空气会使纤维素发生降解,而且随空气量的增加和溶解摇动时间的延长,纸浆的黏度下降。
After interfacial polymerization , the module was filled with a 10 % ( wt . % ) aqueous trimethylamine solution and kept for 24 hours to convert the chloromethylated groups into cationic quaternary ammonium groups 当界面聚合反应完成后,将膜浸入浓度为10的三甲胺溶液郑州大学硕士学位论文中,通过化学修饰将其氯甲基基团转化成阳离子季胺盐基团。
