| description | Composition and method for improving properties of pulp produced or reducing the digester cycle time in alkaline chemical pulping processes in which an effective amount of at least one selected phosphonate or carboxylate compound or mixtures thereof is admixed with the alkaline aqueous mixture in the digester of the chemical pulping process. The compositions and method are especially well suited for use in the Kraft pulping process.
L'invention concerne des compositions et un procédé permettant d'améliorer les propriétés d'une pâte élaborée, ou de réduire la durée du cycle du lessiveur dans des processus de production de pâtes chimiques alcalines; une quantité efficace d'au moins un composé phosphonate ou carboxylate sélectionné, ou des mélanges de ceux-ci, étant ajoutée au mélange aqueux alcalin dans le lessiveur pendant le processus de production de pâtes chimiques. Les compositions et le procédé décrits dans cette invention conviennent tout particulièrement au procédé Kraft. |
