| 摘要:本研究系统探讨了搅拌桨组合对水基泡沫性能的影响，综合分析了发泡速率、空气含量、泡沫半衰期及泡沫半径等关键指标。以搅拌桨类型、组合、直径、间距以及流场作为自变量，3和8 min泡沫半衰期作为因变量进行多元线性拟合，得到相关系数均>0.9，并借助主成分分析（PCA）明确了各变量对泡沫性能的贡献程度。结果表明，搅拌桨的组合形式是决定泡沫性能的主导因素，其中双直叶桨组合表现出最佳的发泡速率和泡沫稳定性。此外，空气含量与泡沫半衰期具有显著正相关性，拟合结果的相关系数达0.8以上，验证了其线性关系，通过截距证明泡沫体系需达60%空气含量才可符合空气含量-泡沫半衰期线性方程。并基于对泡沫体系性能研究引入高长径比石英纤维，筛选单层直叶桨作为石英纤维泡沫成形搅拌起泡装置。 |
| Abstract:This study systematically investigated the influence of stirrer combinations on the performance of water-based foams， with a comprehensive analysis of key parameters including foaming rate， air content， foam half-life， and bubble radius. Stirrer type， combination form， diameter， spacing， and flow pattern were used as independent variables， while the 3-minute and 8-minute foam half-lives were treated as dependent variables for multiple linear regression analysis. The results yielded correlation coefficients greater than 0.9. Principal component analysis (PCA) was further employed to clarify the contribution of each variable to foam performance. The results showed that the configuration of the stirrer combination was the dominant factor affecting foam performance， among which the double Rushton turbine blade combination demonstrated the highest foaming rate and foam stability. In addition， air content showed a significant positive correlation with foam half-life， with correlation coefficients exceeding 0.8， confirming their linear relationship. The intercept of the regression equation suggested that an air content of at least 60% was required for the linear model between air content and foam half-life to be valid. Subsequently， based on the study of the foam system’s performance， high aspect ratio quartz fibers were introduced， and a single-layer Rushton turbine blade was selected as the stirring and foaming device for the quartz fiber foam forming. |
