POLYAMIDE COMPOSITE MEMBRANE PREPARATION PROCESS

摘要

On the fine porous surface, multi-functional amine solution and multi-functional acid-halogen solution have been interfaced and polymerized so that the bridge-polyamide compound osmotic film is produced. The normal alkane having more than eight carbons, the structural isomer of saturated and unsaturated hydrocarbon having eight carbons and an annex are compounded and used as the solvent of multi-functional halogen solution. The annexes are acetone and one component between dimethyl ether and butyl ether.
