摘要
本文报道了聚砜胺(PSA),聚砜胺/磺化聚芳醚砜(SPES—C),聚偏二氟乙烯(PVDF)/磺化聚芳醚砜平板超滤膜的制备工作,所得膜截留分子量(MWCO)分别为30000-70000,1000-20000,100000。并对北京醋进行了澄清过滤试验。工业试验结果表明,用PVDF/SPES—C超滤膜,20m2平板超滤机上醋产量为600—800L/m2.h,产量稳定,清洗容易,满足生产需要。
The preparation of polysulfonamide(PSA),PSA/sulfonated polyaryethersulfone(SPESC),polyvinylidenefluoride(PVDF)/SPES-C ultrafiltration membranes with MWCOs 3000070000,1000-20000, 1000000 respectively is reported in this paper.It is showed that,usingPVDF/SPES-C UF membrane(MWCO 100000).on a 20 m2 plate and frame UF machine,theproduction can reach 600-800 L/h for clarification of Peking vinegar,and the membrane can becleaned easily.
