摘要
用醋酸纤维素(CA)为聚合物材料,研制出了截留分子量2000—10000、对PEG截留率为90％以上的小孔径超滤膜.并就铸膜液组成,制膜条件及膜的透过特性等进行了实验.
The paper deals with preparation of ultrafiltration membrane which intercepts the matter of molecular weight; 2000-10000 and by which interception rate of PEG is over 90%. The components of the membrane, processing conditions and its penetrative characteristics have been tested.
