| 目的 解决纤维素基泡沫制备过程烦琐、湿泡沫的稳定性差的问题。方法 通过单因素试验，考察了十四醇(TDA)、阿拉伯胶(GAC)质量浓度对双膜气泡的稳定性的影响，在此基础上，采用泡沫成形法制备纤维素水基湿泡沫，通过探究合适的十二烷基硫酸钠(SDS)质量浓度、蔗渣原纤浆质量浓度和搅拌速率进一步提高纤维素水基湿泡沫的稳定性。结果 TDA和GAC质量浓度分别为0.015 g/mL和0.010 g/mL时是制备双膜气泡的最佳条件。当SDS质量浓度为0.015 g/mL、蔗渣原纤浆(BF)质量分数为1.8%、搅拌速率为2 000 r/min时，纤维素水基湿泡沫稳定性达到最佳。结论 构建了稳定的纤维素水基泡沫，为纤维素基泡沫提供了一种简单、可行的方法。 |

| The works aims to solve the problem of complicated preparation process and poor stability of aqueous foam. By single factor test, the effects of concentrations of tetradecyl alcohol (TDA) and gum arabic (GAC) on the stability of double film bubbles were investigated. On this basis, cellulose-based aqueous foam was prepared by foam forming method. The stability of cellulose-based aqueous foam was further improved by exploring appropriate concentration of sodium dodecyl sulfate (SDS), concentration of bagasse fibrillated fiber and stirring rate. The result was that TDA and GAC concentrations of 0.015 g/mL and 0.010 g/mL were the best conditions for preparation of double film bubbles. When the SDS concentration was 0.015 g/mL, the bagasse fibrillated fiber (BF) concentration was 1.8 wt.%, and the stirring rate was 2 000 r/min, the cellulose-based aqueous foam achieved the best stability. The stable cellulose-based aqueous foam is constructed, which provides a simple and feasible method for cellulose-based foam. |
