Abstract

L'INVENTION A POUR OBJET UNE MEMBRANE CYLINDRIQUE ECHANGEUSE DE CATIONS POUR L'UTILISATION DANS UNE CELLULE ELECTROLYTIQUE DU TYPE EN DOIGT. SELON L'INVENTION, LES ZONES DE LADITE MEMBRANE NE FAISANT PAS FACE A LA SURFACE ELECTROLYTIQUE EFFICACE DE L'ANODE DE LADITE CELLULE ONT UNE RIGIDITE PLUS GRANDE ET UNE PERMEABILITE AUX ANIONS PLUS FAIBLE QUE LES ZONES DE LA MEMBRANE FAISANT FACE A LA SURFACE ELECTROLYTIQUE EFFICACE DE L'ANODE. APPLICATIONS: PLACEE DANS UNE CELLULE D'ELECTROLYSE DE CHLORURE ALCALIN, ELLE PERMET D'OBTENIR UN HYDROXYDE ALCALIN CONTENANT MOINS DE CHLORURE QU'AVEC LES MEMBRANES HABITUELLES.
