PROCEDURE FOR PRODUCING MICROPOROUS POWDER OR MOLD (MEMBRANES) IN THE FORM OF FLAT SHEETS, FLEXIBLE SHEETS OR HOLLOW FIBERS APPLIED FOR EMISSION OF REGULATED ACTIVE SUBSTANCE, DIALYSIS, GAS SEPARATION, ULTRAFILTRATION OR MICROFILTRATION. THEY ARE PRODUCED THROUGH PHASE SEPARATION THROUGH TRIGGERING NOT INDUCED BY A SOLVENT OR THERMALLY INDUCED OF POLYVINYLIDENE FLUORIDE AND / OR POLYPHYLPHONE AND / OTILYLORINE AND / OR POLYURYLENE AND / OR OUTERYLENE. / OR POLYETERSULFONE AND / OR POLYETHERMIDE AND / OR POLYMETHYLMETHACRYLATE AND / OR POLYCARBONATE AND / OR CELLULOSE TRIACETATE. A SOLUTION OF THE POLYMERS IS PRODUCED IN A MIXTURE CONTAINING E-CAPROLACTAM AS A SOLVENT COMPONENT, THE SOLUTION IS CONFORMED AND THE PHASE SEPARATION IS UNLOCKED. |
