PVC分离膜的改性研究进展

Research Progress on PVC Membrane

聚氯乙烯(PVC)作为世界第二大合成树脂,不仅耐化学腐蚀性强,耐微生物侵蚀,而且其机械强度高,成膜性好,价格低廉,因而近年来引起分离膜研究者的兴趣。但由于其本身热稳定性差且具有疏水性,因此抗污染性能差。所以在使用过程中为了优化其性能,对PVC分离膜要进行改性处理。因此本文总结了近年来PVC膜的研究进展与几种改性方法。

As the world's second largest synthetic resin, polyvinyl chloride (PVC) is not only resistant to chemical corrosion, but also resistant to microbial attack.It has high mechanical strength, good membrane formation and low price, which has caused interest in researchers of separation membranes in recent years.However, due to its poor thermal stability and hydrophobicity, the anti-pollution performance is not well.Therefore, in order to optimize its performance during use, various modifications are required for PVC membrane.Therefore, the research progress and several modification methods of PVC membrane in recent years were reviewed.
