Title (EN) ADDITIVE AND METHOD FOR IMPROVING DEWATERING EFFICIENCY IN PAPER MANUFACTURING
(FR) ADDITIF ET PROCÉDÉ POUR AMÉLIORER L'EFFICACITÉ DE DÉSHYDRATATION DANS LA FABRICATION DE PAPIER
Abstract:
(EN) The invention provides an additive and method for improving dewatering efficiency in a paper making process. The dewatering additive is prepared from the same wood that is used as raw material for preparing the paper, which may be insulation paper or pressboard. The dewatering additive may be prepared from the same pulp that is used for preparing a stock for paper / pressboard forming. The dewatering additive is added to the pulp for preparing the stock that is supplied through various sections of the paper machine for making paper.
(FR) L'invention a trait à un additif et un procédé pour améliorer l'efficacité de déshydratation dans un processus de fabrication de papier. L'additif de déshydratation est préparé à partir du même bois qui est utilisé comme matière première pour préparer le papier, qui peut être du papier d'isolation ou du carton comprimé. L'additif de déshydratation peut être préparé à partir de la même pâte à papier qui est utilisée pour préparer une pâte pour la formation de papier/carton. L'additif de déshydratation est ajouté à la pâte à papier pour préparer la pâte qui est fournie à travers diverses sections de la machine à papier pour fabriquer du papier.
