MANUFACTURING METHOD OF COMPOSITE MEMBRANE

摘要

corona discharging a non woven fabric or fabric cloth in the condition of 10-15 watt discharge generating power and 20-40 sec. treating time, spraying water and casting porous supported substance 5-10 sec. later, and then accumulating an activated layer of cross-linked polyamide based ultra-thin film obtained by interfacial polycondensation of multifunctional amine solution and multifunctional halogen solution onto a surface of the supported body.
