摘要

摘要本文介绍了椰油酰胺丙基甜菜碱(CAPB)和DEA椰油酰胺溶液在添加乙二醇时流动压降的实验研究结果。CAPB/DEA水溶液流动时的减阻程度与添加10%乙二醇时相似。当乙二醇浓度为20%时，压降也显著降低。然而，乙二醇浓度的增加导致在较高温度下流动阻力的降低。CAPB/DEA溶液的胶束微观结构对机械降解的抵抗力很大程度上取决于pH水平。当初始pH为碱性时，流动特性发生了显著变化。随着时间的推移，初始pH值接近中性的溶液是稳定的，尽管也观察到随着时间的推移，抗降解性降低。

Pressure drops during the flow of solutions of cocamidopropyl betaine and cocamide DEA mixtures with the addition of ethylene glycol

Abstract The paper presents the results of experimental studies on pressure drops during the flow of cocamidopropyl betaine (CAPB) and DEA cocamide solutions with the addition of ethylene glycol. The degree of drag reduction during the flow of the CAPB/DEA aqueous solution and with the 10% addition of ethylene glycol was similar. A significant reduction in pressure drops was also observed at the 20% concentration of ethylene glycol. However, the increase in the concentration of ethylene glycol resulted in the reduction of flow resistance at higher temperatures. The resistance of the micellar microstructure of CAPB/DEA solutions to mechanical degradation depends strongly on the pH level. Significant changes in flow properties were observed when the initial pH was alkaline. The solution with initial pH close to neutral was stable over time, though reduced resistance to degradation with time was also observed.
