Prepn. of membrane with oriented mol. sieve crystals as transport component - by orienting crystals on lower condenser electrode, transferring to upper electrode, fixing, embedding in matrix etc.

摘要: In prepn. of membranes (a) synthesised mol. sieve crystals, in a fluid medium are applied (dis)continuously to the lower one horizontally arranged electrodes condenser and oriented at field strength 1 V/mm-10kV/mm with their length parallel field, (b) part crystals is moved suddenly from upper electrode, adheres there, by raising tension above value needed for orientation, while retaining (c) on or electrode fixed hardened thin (in)organic layer, (d) embedded matrix, (e) properties pepd. matrix suitable sepn. removal techniques. USE/ADVANTAGE - Such used mixts. diffusion, permeation pervaporation, dimensionally selective membrane catalysis, as components chemical sensors. The have definite pore dia. 2-20 Angstroms, material transport least mainly determined molecular crystals. They chemical, thermal mechanical stability, acceptable flow densities high selectivity, resist fouling, not sensitive interference, easily regenerated
