Abstract
L'invention porte sur un procédé de fabrication de papier à partir de fibres de cellulose dispersées dans un milieu aqueux. Au cours de ce procédé, du dioxyde de carbone est injecté dans la pâte, directement ou au moyen d'un excipient aqueux, avant l'addition d'adjuvants chimiques afin de contrôler le besoin en ions et le potentiel zêta en aval, notamment au cours de l'addition d'adjuvants. Plus particulièrement, ces adjuvants sont ajoutés dans une chambre de mélange (2) et du dioxyde de carbone est ajouté dans l'eau blanche sur le côté sortie du désintégrateur de cassés de fabrication (15) ou dans le système court (9).
