Title
(EN) METHOD FOR IMPROVING FILLER AND FIBER RETENTION IN PAPER MAKING PROCESSES
(FR) PROCÉDÉ POUR AMÉLIORER LA RÉTENTION DE CHARGE ET DE FIBRES DANS DES PROCÉDÉS DE FABRICATION DE PAPIER
Abstract
(EN)
A process and device for improving filler retention of paper, paperboard, or cardboard. The process provides for an electromagnetic force being applied to a filler material and/or cellulosic furnish, thereby changing the surface charge of the filler material and/or cellulosic furnish and forming a paper, paperboard, or cardboard product.
(FR)
L'invention concerne un procédé et un dispositif pour améliorer la rétention de charge de papier, de carton-pâte ou de carton. Le procédé permet d'appliquer une force électromagnétique à un matériau de charge et/ou à une composition cellulosique, ce qui permet de modifier la charge de surface du matériau de charge et/ou de la composition cellulosique et de former un produit en papier, en carton-pâte ou en carton.
