【摘要】：采用浸沒沉淀相轉化法制備了純聚偏氟乙烯(PVDF)平板超濾膜,并對制膜條件進行了討論,通過對膜的純水通量、牛血清白蛋白溶液通量和截留率的測試來考察PVDF超濾膜的性能。結果表明:溶劑種類,聚合物濃度,致孔劑濃度,凝固浴的組成和溫度,預蒸發(fā)時間,刮膜速度及刮膜厚度等因素對膜的制備均有較大影響。
[Abstract]:The pure polyvinylidene fluoride (PVDF) flat plate ultrafiltration membrane was prepared by immersion precipitation phase inversion method, and the preparation conditions were discussed. The performance of PVDF ultrafiltration membrane was investigated by testing the pure water flux, bovine serum albumin solution flux and retention rate. The results showed that the kinds of solvents, the concentration of polymer, the concentration of pore-forming agent, the composition and temperature of coagulation bath, the time of pre-evaporation, the rate of scraping film and the thickness of scraping film had great influence on the preparation of the film.
