| 摘 要： | 通过干-湿相转化法,制备聚氯乙烯（PVC）/聚乙烯醇缩丁醛（PVB）共混平板超滤膜;考察了3种不同型号的PVB型号、添加剂聚乙二醇（PEG）和聚乙烯吡咯烷酮（PVP）在铸膜液中的含量的不同对共混超滤膜性能的影响。结果表明PVB对PVC共混改性可有效改善膜的性能,在不同型号的PVB中PVB-60T对膜亲水性和分离性能改善最为显著;当PEG含量为5%,PVP含量分别为5%和1%时,PVC/PVB共混膜分离性能较佳,纯水通量为510.1L/（m2.h）,截留率为98%。 |

| Abstract: | Polyvinyl chloride(PVC)-polyvinyl butyral(PVB) blend ultrafiltration membrane was prepared by using phase-inversion technique.The effects of using three different types of PVB and the contents of the additives,i.e.polyethylene glycol(PEG) and polyvinyl pyrrolidone(PVP),in the casting solution on the performance of the blend membrane were investigated.The experimental results demonstrated that the hydrophilicity and the water flux of the blend membrane were much better than those of the PVC membrane.The perf... |
