一种含羧基表面活性剂HDXA界面特性研究

通过系统研究一种含羧基表面活性剂HDXA的界面张力特性,表明在一定条件下,该表面活性剂在0.05%~0.4%的范围内可形成10-3mN/m数量级的超低界面张力,添加剂的加入能使油水界面快速的达到最低界面张力,其中最低界面张力和稳定界面张力值均低于单一表面活性剂体系,活性剂HDXA浓度不同时,最佳添加剂浓度也随之改变。不同活性剂浓度达到最低界面张力及稳态界面张力的时间也不同,随着浓度的增大依次缩短。

Investigation of interfacial properties of a carboxylic surfactant HDXA

Systematic investigation of interfacial tension of a carboxylic surfactant HDXA has revealed that ultralow interfacial tension of 10-3 mN/m order can be formed within the limit of 0.05%~0.4% under certain conditions.The interfacial tension of the oil-water interface can reach the minimum immediately when additives were added into the system,and the values of minimum interfacial tension and stable interfacial tension were both lower than that of the single surfactant system,the optimum additive concentration will be different when the HDXA concentration of the active agent changed.Time to reach the minimum interfacial tension and stable interfacial tension varies with different surfactants,which will shorter as the concentration increases.
