通过对阴离子-非离子表面活性剂、非离子-非离子表面活性剂复配体系的起泡性和稳泡性研究发现,聚醚类非离子表面活性剂参与的复配体系泡沫性均较差。在体积比为1∶1时,APG与AEO、APG与OP-10复配体系在6和8 h的稳泡性高于单剂的稳泡性;在SDS与AEO的复配体系中,当体积比为1∶1时,从2~8 h该复配体系的稳泡性一直高于单剂的稳泡性。由此可见,SDS和APG复配体系均具有较好的泡沫性能,但非离子表面活性剂的起泡性和稳泡性均较低。

The foaming performance and foam stability of anionic/non-ionic surfactants and non-ionic/non-ionic surfactants complex systems are studied.It is found that the complex systems involving in polyether nonionic surfactants always have poor foaming properties.Under a volume ratio of 1∶1,both APG/AEO and APG/OP-10 complex systems exhibit better form stability at 6 h and 8 h time point than single agent.Under a volume ratio of 1∶1,SDS/AEO system has always shown a higher foam stability from 2 h to 8 h than single agent.It can be concluded that both SDS-containing and APG-containing complex systems have good foaming performance,and non-ionic surfactants show low foam property and foam stability.
