| description | A method is described for making paper or paper board by applying a composition containing enzyme and cationic coagulant to papermaking pulp prior to paper forming to preferably improve drainage, retention, or both. Sheets of pulp from which paper or paperboard products are made with the method can exhibit excellent drainage, excellent retention of pulp fines, or both. The method also can be applied to other pulp treatments, such as waste water treatments. A system for making such treatments of paper furnish is also provided.
L'invention concerne une méthode de fabrication de papier ou de carton en appliquant une composition contenant un enzyme et un coagulant cationique à la pâte à papier avant la fabrication du papier pour améliorer de préférence l'égouttage ou la rétention, ou les deux. Les feuilles de pâte qui serviront à la fabrication des produits en papier ou en carton avec la méthode peuvent présenter un égouttage excellent, une rétention excellente des fines de pâte, ou les deux. La méthode peut aussi être utilisée pour le traitement d'autres pâtes, tel que le traitement des eaux usées. L'invention concerne aussi un système pour réaliser ces traitements d'une composition de papier. |
