Abstract:
(DE) Verfahren zur Herstellung von Papier, Pappe und Karton durch Entwässern eines Störstoffe enthaltenden Papierstoffs in Gegenwart von Fixiermitteln, wobei man als Fixiermittel Umsetzungsprodukte einsetzt, die durch Reaktion von Amino- und/oder Ammoniumgruppen enthaltenden Polymeren aus der Gruppe: der Vinylamineinheiten enthaltenden Polymerisate; Polyalkylenpolyamine; Polyamidoamine; mit Ethylenimin gepfropften Polyamidoamine, die gegebenenfalls vernetzt sind; Polydiallyldimethylammoniumchloride; Dialkylaminoalkylacrylamid-Einheiten oder Dialkylaminoalkylmethacrylamid-Einheiten enthaltenden Polymeren; Polyallylamine und Dicyandiamid-Formaldehyd-Kondensate mit Reaktivleimungsmitteln für Papier im Gewichtsverhältnis Polymer zu Reaktivleimungsmittel von 15 000 : 1 bis 1 : 1 erhältlich sind und Verwendung der so erhältlichen Umsetzungsprodukte als Fixiermittel für wasserlösliche und für wasserunlösliche Störstoffe bei der Herstellung von Papier, Pappe und Karton aus Störstoffe enthaltenden Papierstoffen.
(EN) The invention relates to a method for producing paper, paperboard and cardboard by dehydrating paper material containing interfering substances in the presence of fixing agents. Reaction products are used as fixing agents. Said products are obtained by reacting polymers, containing amino and/or ammonium groups, from the group of: polymers containing vinyl amino units, polyalkylene polyamines, polyamidoamines, polyamidoamines grafted with ethylene imine and optionally cross-linked, polydiallydldimethylammoniumchlorides; polymers containing dialkylaminoalkylacrylamide-units or dialkylaminoalkylmethacrylamide units and polyallylamines and dicyandiamide-formaldehyde-condensates, with reactive sizing agents for paper with a polymer/reactive sizing agent weight ratio of 15,000 : 1 to 1 : 1. The invention also relates to reaction products thus obtained and to their use as fixing agents for water soluble and water insoluble interfering substances in the production of paper, paperboard and cardboard from paper materials containing interfering substances.
(FR) L'invention concerne un procédé pour produire du papier, du carton souple et du carton épais par déshydratation d'une pâte de papier contenant des substances perturbatrices, en présence d'agents de fixation, les agents de fixation utilisés étant des produits de réaction obtenus par réaction de polymères contenant des groupes amino et/ou ammonium et sélectionnés dans le groupe comprenant: des polymérisats contenant des unités vinylamine; des polyamines de polyalkylène; des polyamidoamines; des polyamidoamines greffées par imine d'éthylène, pouvant éventuellement être réticulées; du chlorure de polydiallyldiméthylammonium; des polymères contenant des unités dialkylaminoalkylacrylamide ou des unités dialkylaminoalkyleméthacrylamide et des condensats dicyandiamide-formaldéhyde; avec des agents d'encollage réactifs pour papier, dans un rapport en poids polymère/agent d'encollage réactif de 15.000 : 1 à 1 : 1. L'invention concerne en outre l'utilisation des produits de réaction ainsi obtenus, comme agents de fixation pour des substances perturbatrices solubles dans l'eau ou non, dans le cadre de la fabrication de papier, de carton souple et de carton à partir de pâtes à papier contenant des substances perturbatrices.
