DEVICE FOR PRODUCTION OF DIFFUSION POLYMER MEMBRANES Russian patent published in 2014 - IPC B01D67/00 C08J5/22 B29C67/20 B82B3/00 C08K13/02 B01D71/28 

FIELD: process engineering.

SUBSTANCE: invention relates to membrane technologies and can be used in food, chemical, petrochemical industries, etc, for cleaning and separation of different process fluids. Proposed device comprises first reaction chamber with impeller connected via pump with second reaction chamber. Second reaction chamber incorporates bin for feed of extra component and ultrasound wave radiator for activation of polymer composition. First, composition is produced inside first reaction chamber at mixing polyvinyl alcohol, water and fullerenol C₆₀-(OH)_22-24. Then, it is fed into second reaction chamber wherein fed in extra component, a maleic acid, is fed to activate the mix. Composition produced in second reaction chamber is used to form the membrane on the substrate to be fed into drying chamber for heat treatment. Produced membrane features transport properties, efficiency and selective extraction of water from water-containing mixes.

EFFECT: lower costs of membrane production.
