Abstract

Se refiere métodos, composiciones, y aparatos para aumentar la resistencia del papel realizado con una pasta de papel que tiene una gran proporción de OCC. El método incluye los siguientes pasos: 1) proporcionar una pasta de papel que tiene una gran cantidad de OCC en ella, 2) agregar un promotor de resistencia a la pasta antes de agregar un agente de resistencia a la pasta, 3) agregar un agente de resistencia a la pasta, y 4) realizar un producto de papel a partir de la pasta de papel. Este método permite el uso de material de OCC barato en un proceso de fabricación de papel sin los problemas de calidad que causa normalmente el desecho aniónico en el OCC. De este modo, pueden producirse los productos de papel que tienen bajos costos y alta calidad.
