摘要
采用聚甲醛长丝和聚四氟乙烯长丝进行交织作为支撑基布,耐腐蚀乙烯酯树脂作为粘合剂,制备强碱 性废水处理用支撑聚四氟乙烯滤膜.研究了不同交织密度机织支撑基布与聚四氟乙烯微滤膜复合后对聚四氟乙烯复合膜的水通量、孔径变化、剥离强力、硬挺度的变化,研究结果表明：随着交织密度增加、树脂附着量增大,膜孔径、 水通量均有所减小,剥离强力变化最为明显; 22.2tcx× 15.6tcx、 160×110根/10 cm 的聚四氟乙烯长丝和聚甲醛长丝与聚四氟乙烯膜复合后综合性能最好.
In this paper,polyoxymethylene filament and PTFE filament were interwoven as a supporting fabric,and the anti-corrosive vinyl ester resin was used as the adhesive to prepare PTFE membrane support fabric used in strong alkaline waste-water filtration.The effects of weaving density after compounding with PTFE micro-filtration membrane on the pore size,water flux,stiffness and peel strength of PTFE support membranes were investigated.The results show that:with the increase of interweaving density,the pore size and water flux of membrane decreases,and the change in peeling strength is most obvious.The membrane supported with the base fabric of 22.2tex×15.6tex,160×140picks/10 cm has the best comprehensive properties.
