摘　　要：以发泡剂掺量为单一变量,研究了不同表面活性物质浓度对发泡倍数和稳泡性能的影响,并通过掺加纳米颗粒的方式对K12溶液稳泡性能进行了改性。研究结果表明:AES、K12、AOS、AEO-9、茶皂素浓度提升对发泡剂发泡能力和泡性能有利,且通过极差分析可知,以上几种表面活性物质浓度对于发泡体积的影响程度差别不大,对于稳泡性能的影响程度有较大差距,其中K12影响最大,CMEA影响最小,疏水纳米SiO_(2)可极大地提升稳泡效果。In this paper,the mixing amount of foaming agent was used as a single variable to study the effects of surfactant concentrations on the foaming volume and foaming stability,and the foaming stability of K12 solution was modified by adding ganamate particles.The results show that:AES,K12,AOS,AEO-9,concentration of tea saponin ascension to improve the effects of foaming ability and stability of foaming agent,and through the analysis of the poor,the above several kinds of surface active substance concentration to the influence degree of the foam volume is a huge difference,for the influence degree of the foam stability have larger gap,which has the greatest effect in the K12,CMEA minimal impact,hydrophobic nano-SiO_(2) can greatly improve the foam stabilizing effect.
