Abstract

Procedimiento para la fijación de impurezas en la fabricación de papel, que abarca las siguientes etapas: a) Puesta a disposición de una bentonita, realizándose que la proporción de los cationes monovalentes en la capacidad de intercambio de cationes (CEC) de la bentonita se sitúa en por lo menos 0,7 y la CEC es de más que 85 meq/100 g, de manera preferida de más que 90 meq/100 g, en particular de más que 95 meq/100 g. b) Adición de la bentonita de acuerdo con a) a una pasta papelera o respectivamente a una suspensión de pasta fibrosa; c) Fijación de las impurezas a la bentonita en la pasta papelera o respectivamente en la suspensión de pasta fibrosa.Procedure for fixing impurities in papermaking, which covers the following stages: a) Making a bentonite available, making the proportion of monovalent cations in the cation exchange capacity (CEC) of bentonite situated at least 0.7 and the ECC is more than 85 meq / 100 g, preferably more than 90 meq / 100 g, in particular more than 95 meq / 100 g. b) Addition of the bentonite according to a) to a pulp or a fibrous pulp suspension respectively; c) Fixing impurities to bentonite in paper pulp or respectively in the fibrous pulp suspension.
