聚乙烯醇/聚砜复合膜用于水—乙醇液体混合物分离的渗透性能研究
Gongye shui chuli, 1990 本文研究了底膜的性能对渗透气化性能的影响,制备了不同孔径结构底膜,研究了铸膜液PS浓度、添加剂对水通量的影响,用电镜观察了复合膜的结构,结果表明底膜的差别造成了复合膜的不均匀性,进而影响了复合膜的渗透性能。

Jianzhu Gangjiegou Jinzhan, 2010 膜结构施工中膜张力的测量与控制以及使用中膜材张力的检测,是确保膜结构稳定与安全的重要因素。膜张力计是一种简便实用的装置,可以在不破坏膜材且不影响膜内力分布的条件下分别测定纬向和经向的张力。本文用有限元软件ANSYS模拟膜张力计测量FGT-800膜材的初始张力,分别沿着纬向和经向在压力容器范围内施加平面外均布荷载后,通过计算膜平面外最大位移来推算膜平面内纬向和经向的初始张力。用最小二乘法拟合有限元分析结果,得出了更合适的膜张力拟合公式,其中膜张力简化拟合公式相对误差在±4%之内 ...
