Title (EN) METHOD FOR MAKING PAPER AND CARDBOARD WITH HIGH DRY STRENGTH AND RESULTING PAPERS AND CARDBOARDS
(FR) PROCEDE DE FABRICATION DE PAPIER ET CARTON DE GRANDE RESISTANCE A SEC ET PAPIERS ET CARTONS AINSI OBTENUS
Abstract: front page image
(EN)The invention concerns a method for making a sheet of paper and/or cardboard and the like, which consists, prior to forming said sheet, in adding to the fibrous suspension, separately or mixed, in any sequence of introduction, into one or more injection points, at least three dry strength agents respectively: a first agent corresponding to a (co)polymer having a cationic filler density higher than 1 meq/g and exhibiting primary amine functions; a second agent corresponding to a synthetic organic (co)polymer having a cationic filler density higher than 0.1 meq/g; and a third agent corresponding to a (co)polymer having an anionic filler density higher than 0.1 meq/g.
(FR)Procédé de fabrication d'une feuille de papier et/ou de carton et analogues, selonlequel, avant formation de ladite feuille, on ajoute à la suspension fibreuse, séparément ou en mélange, dans un ordre quelconque d'introduction, en un ou plusieurs points d'injection, au moins trois agents de résistance à sec respectivement : - un premier agent correspondant à un (co)polymère ayant une densité de charge cationique supérieure à 1 meq/g et présentant des fonctions aminé primaire, - un second agent correspondant à un (co)polymère organique synthétique ayant une densité de charge cationique supérieure à 0,1 meq/g,- et un troisième agent correspondant à un (co)polymère ayant une densité de charge anio nique supérieure à 0,1 meq/g.
