Abstract

Procedimiento para la estabilización del pH de una suspensión de pulpa en la preparación del material de partida de una máquina para la fabricación de papel, utilizando dióxido de carbono, caracterizado por incrementar la capacidad tampón de dicha suspensión de pulpa para la máquina de fabricación de papel por adición a la misma de una combinación formada por un producto de alimentación de un hidróxido de metal alcalino y un producto de alimentación de dióxido de carbono, cuyos productos de alimentación contrarrestan substancialmente sus respectivos efectos de cambio de pH, facilitándose dichos productos de alimentación en una cantidad suficiente para conseguir un efecto tampón significativo de dicha suspensión de pulpa y ajustando el pH de dicha suspensión de pulpa por adición de un exceso de dicho hidróxido o dicho dióxido de carbono para mantener el pH a un nivel deseado en la subsiguiente fabricación de papel.
