METHOD OF PRODUCING TUBULAR FILTRATION ELEMENT WITH POLYMER MEMBRANE

摘要

FIELD: process engineering.SUBSTANCE: invention relates to production of membranes. Method of producing tubular filtration element with polymer membrane for filtration of fluids includes diluting membrane-forming polymer: sulfonic polyester, polysulfone or PVC and modifying additive. Obtained solution is applied on inner surface of vertically arranged open-pore tube to be hardened. Said modifying additive represents the mix of Laproxide with polyethylenamine, or piperazine, or diphenylamine.EFFECT: hydrophilic membranes with higher technical performances.3 tbl
