(FR) SYSTÈME ET PROCÉDÉ
Abstract
(EN)
A process for manufacturing paperboard liner (PBL) for plaster board, including the steps of receiving virgin Kraft fibre ( VKF); receiving recycled paper fibre (RCF); blending the VKF and the RCF to produce multiple fibre blend streams; forming said streams into paper plys; forming the plys into a multi ply paper sheet; chemically sizing the paper sheet to increase hydrophobicity; and drying the multi ply paper sheet over drying drums to produce the PBL, wherein the PBL is no more than 140 grams per square meter (gsm).
(FR)
L'invention concerne un procédé de fabrication de revêtement de carton (PBL) pour une plaque de plâtre cartonnée, comprenant les étapes consistant à recevoir une fibre de papier kraft vierge (VKF) ; à recevoir une fibre de papier recyclé (RCF) ; à mélanger la VKF et la RCF pour produire de multiples flux de mélange de fibres ; à former lesdits flux en plis de papier ; à former les plis en une feuille de papier à plis multiples ; à dimensionner chimiquement la feuille de papier pour augmenter l'hydrophobicité ; et à faire sécher la feuille de papier à plis multiples sur des tambours de séchage pour produire le PBL, le PBL ne faisant pas plus de 140 grammes par mètre carré (gsm).
