Abstract

L'invention concerne un procédé de traitement des diaphragmes en amiante de cellules d'électrolyse industrielle. On introduit des particules d'un silicate alcalino-terreux,dans la saumure à électrolyser. Le dépôt de la dispersion à l'intérieur du diaphragme entraîne une diminution de la concentration de H2 dans Cl2 gazeux produit, et une augmentation du rendement du courant. Application : traitement de renforcement du diaphragme poreux de cellules d'électrolyse d'une saumure de chlorure alcalin.
