Abstract

L'INVENTION A POUR OBJET UN PROCEDE DE JONCTION DE MEMBRANES ECHANGEUSES DE CATIONS EN POLYMERE FLUORE. ON TRAITE LES MEMBRANES ECHANGEUSES DE CATIONS EN UN POLYMERE FLUORE, PORTANT DES GROUPES LATERAUX -COOH SUR AU MOINS UNE FACE, AVEC UNE AMINE TERTIAIRE OU UNE BASE D'AMMONIUM QUATERNAIRE, PUIS ON PRESSE A CHAUD LES MEMBRANES AINSI TRAITEES. UTILISATION DES MEMBRANES AINSI UNIES DANS DIVERSES APPLICATIONS INDUSTRIELLES, NOTAMMENT DANS LES CELLULES ELECTROLYTIQUES.THE SUBJECT OF THE INVENTION IS A PROCESS FOR JOINING CATION-EXCHANGING MEMBRANES IN FLUORA POLYMER. THE CATION-EXCHANGING MEMBRANES IN A FLUORINE POLYMER, CARRYING -COOH LATERAL GROUPS ON AT LEAST ONE SIDE, WITH A TERTIARY AMINE OR A QUATERNARY AMMONIUM BASE, THEN THE MEMBRANES THEN TREATED ARE HOT PRESSED. USE OF MEMBRANES SO UNITED IN VARIOUS INDUSTRIAL APPLICATIONS, ESPECIALLY IN ELECTROLYTIC CELLS.
