摘要:

研究了不同类型表面活性剂种类对不同极性有机溶剂发泡性能的影响规律。通过与常规表面活性剂乙氧基硬脂醇的溶液性能和发泡性能进行对比,特种表面活性剂在最大发泡体积和排液半衰期以及泡沫粒径分布三个方面表现出优良性能。研究表明:和添加C18E9相比,在甲酰胺中加入FC-170C使得最大泡沫含气率从77.7%上升至80.6%,半衰期从123 s上升至394 s;在乙酸乙酯中加入PDMS使得最大泡沫含气率从25.4%上升至30.6%,半衰期从53 s上升至55 s。在乙酸苄酯中加入DDAB改变了乙酸苄酯不发泡的现状,最大泡沫含气率为39.0%,半衰期为64 s。在甲苯中加入FC-170C改变了甲苯不发泡的现状,最大泡沫含气率为44.4%,半衰期为113 s。在癸烷中加入DDAB时,发泡性能最好,最大泡沫含气率为35.9%,半衰期为42 s。特种表面活性的发泡性能优于普通表面活性剂。强极性溶剂的发泡性能优于弱极性溶剂,添加同种表面活性剂,甲酰胺溶液产生的泡沫更稳定,发泡体积也更大。

Abstract:

The effects of different types of surfactants on the foaming performance of organic solvents with different polarities were investigated. Compared with the solution and foaming performance of conventional surfactant stearyl alcohol ethoxylate, the special surfactants showed excellent performance in the aspects of maximum foam volume, drainage half-life and bubble size distribution. Compared with the addition of C18E9, the introduction of FC-170C into formamide raised the maximum foam air content from 77.7% to 80.6%, and extended the half-life from 123 s to 394 s. Similarly, the addition of PDMS to ethyl acetate raised the maximum foam air content from 25.4% to 30.6%, and increased the half-life from 53 s to 55 s. The introduction of DDAB altered the non-foaming status of benzyl acetate, achieving a maximum foam air content of 39.0% and a half-life of 64 s. The addition of FC-170C changed toluene from non-foaming to foaming, resulting in a maximum foam air content of 44.4% and a half-life of 113 s. The foaming performance was optimal upon the addition of DDAB to decane. The maximum air content of the foam reached 35.9%, with a half-life of 42 s. As to these organic solvents, the foaming performance of special surfactants generally surpassed that of regular surfactant. Solvents with strong polarity were more likely to produce stable foams, the foaming performance of strong polar solvents was superior to that of weak polar solvents. For the same surfactant added, compared with other solvents, the foam produced by formamide solution was more stable and the foam volume was also larger.
