【摘要】 <正> 引言中空纤维反渗透膜的研究在文献中已有很多介绍。然而,直接关于中空纤维反渗透膜的制备仅在专刊中有报导。早先,我们已发表过采用芳香聚酰胺(902—1)为原料,研制中空纤维反渗透膜的初步试验结果。在本文中,我们将详细地报导在纺制中空纤维反渗透膜过程中使用的主要参数和芳香聚酰胺(902—1)中空纤维反渗透膜的性能。更多还原

【Abstract】 Polyamide (902-1)hollow fiber membrane has been spun by a dry jet-wet spinning technique.The spinning parameters were studied and the effects of oparation condition on Performance characteristics of the hollow fiber were examined all well.Performance characteristics of the hollow fiber we obtained are that the waterflux is 0.21-0.28ml/cm~2 h,and the salt rejection is above 95%determined under the pressure of 28kg/cm~2 using 0.15% NaCl solution at 25℃.Theflux decline rate is less than -0.05.This hollow fiber is considered to be suitable for brackish desalination.更多还原
