| 摘 要： | 在醋酸纤维素滤膜基底上制备了氨基改性聚硅氧烷复合薄膜,研究了气体种类、温度、压力等对该薄膜气体渗透系数的影响。结果表明:薄膜对不同气体的渗透系数与气体的临界温度和操作温度具有一定的指数相关,与薄膜两侧的压力差则为线性相关。

| Abstract: | Amino-modified polysiloxane（APS） membrane was prepared using cellulose acetate（CA） microfiltration membrane as basement membrance.The effect of species of gas temperature and pressure difference on permeability coefficient of the APS/CA composite membrane was studied.The results showed that there was index correlation between the permeability coefficient and temperature critical temperature of gas,and the linear correlation between the permeability coefficient and pressure difference. |
