| 摘 要： | 根据有机添加剂和无机添加剂在超滤膜形成过程中所发挥作用的不同，分别选择不同分子量的聚乙二醇和无机盐ＬｉＣｌ，ＺｎＣｌ２，Ｍｇ（ＣｌＯ４）２为添加剂，观测其对聚丙烯腈中空纤维超滤膜性能影响，同时发现，采用复合添加剂在膜孔径进行调节，可以得到孔径小，孔隙率高的中空纤维超滤膜。

| Abstract: | In terms of the different principle of organic and inorganic additives effects on making ultrafiltration membrane, various molecular weight polyethylene glycols (PEG) and three kinds of inorganic salts LiCl, ZnCl 2 and Mg(ClO 4) 2 were chosen as the additives.The influences of various additives on ultrafiltration membrane properties was studied. It hao shown that the use of composite additives to adjust pore diameter could get small pore diameter and high porosity hollow fiber ultrafiltration membrane. |
