The bsa rejection increases as / decreases . the hydrophilicity of the surface of pvdf hollow - fiber membranes has been greatly improved and the antifouling ability increased obviously Pvdf基膜表面引入pamps长链分子或者pamps凝胶层，亲水性大为改善，抗污染能力明显提高。
In order to avoid pollution , we choose polyethylene as the raw material , through heating it in the high temperature and physic extension measure , we get the hollow fiber membrane 中空纤维膜表面分布着0 . 01微米- 0 . 1微米不等的孔径，这些孔径可以去除以往单一的活性炭净水器所不能去除的细菌、铁锈等杂质。
Sf filter has been developed to filter fluid containing fine particles . it consists of hollow fiber membranes . standard sf filtration system is consisted of sf filter module and piping , etc . 压缩空气中含有的油气或碳氢化合物达到5mg m3 ,含水量达到11 mg m3 ,杂质颗粒达到1 . 4亿个m3 ，还有些压缩空气含有异味气体。
Sio2 play an important role to pressure - rvsponsi vity of pe composite hollow fiber membranes . oil - water emulsion was treated using as - spun pu composite ho ] low fiber membranes . the flux decline was very severe compared wi th pure wate 可见，实验所纺的两种中空纤维膜可以应用于油水分离领域，并且当膜污染进行反洗时，膜孔径变大，而工作时膜孔径回复较好。
