Title (EN) IMPROVED METHOD FOR TREATING RECYCLED POLYETHYLENE TEREPHTHALATE
(FR) PROCEDE AMELIORE POUR TRAITER DU POLYETHYLENE TEREPHTALATE RECYCLE
Abstract: front page image
(EN)A process for treating RPET flakes comprises providing a quantity of RPET flakes, comminuting the RPET flakes to prepare RPET particles having an average mean particle size less than about 300 microns, and treating the RPET particles utilizing a low energy process selected from the group consisting of simultaneously melting and mixing the RPET particles by means of a low energy melting device to prepare an RPET melt, and thermally treating the RPET particles to dry or crystallize the RPET particles.
(FR)L'invention concerne un procédé pour traiter des éclats de polyéthylène téréphtalate recyclés (PTER), consistant à obtenir une certaine quantité d'éclats de PTER, à fragmenter ces éclats de PTER pour préparer des particules de PTER possédant une taille moyenne de particule inférieure à environ 300 microns, et à traiter ces particules de PTER au moyen d'un processus à faible énergie choisi dans le groupe comprenant la fonte et le mélange simultanés des particules de PTER au moyen d'un dispositif de mélange à faible énergie pour préparer une matière fondue de PTER ainsi que le traitement thermique des particules de PTER pour sécher ou cristalliser ces particules de PTER.
