Abstract

L'INVENTION CONCERNE UN PROCEDE DE TRAITEMENT DES CORDONS ETOU FILAMENTS DE VERRE RESIDUAIRES QUI SONT PRODUITS PENDANT UNE OPERATION DE FORMAGE DES FIBRES DE VERRE, POUR UN REEMPLOI ULTERIEUR COMME INGREDIENTS DE CHARGE DISCONTINUE POUR UN PROCEDE DE FORMAGE DES FIBRES DE VERRE. CE PROCEDE CONSISTE EN UN TRAITEMENT THERMIQUE A UNE TEMPERATURE CONTROLEE DES CORDONS ETOU FILAMENTS DE VERRE RESIDUAIRES POUR PRODUIRE UN VERRE PARTICULAIRE QUI PEUT ETRE RECYCLE DANS UN FOUR DE FORMAGE DES FIBRES DE VERRE. LE RETRAITEMENT DES CORDONS ETOU FILAMENTS DE VERRE RESIDUAIRES DIMINUE SUBSTANTIELLEMENT LE PRIX DES MATIERES PREMIERES NECESSAIRES POUR UNE OPERATION DE FORMAGE DES FIBRES DE VERRE.
