IMPROVING PROCESSES FOR MAKING PAPER PRODUCTS BY IMPROVING THE PHYSICO-CHEMICAL BEHAVIOR OF PAPER PULP

摘要

The present invention relates to a process for producing paper from cellulosic fibers dispersed in an aqueous medium, a process in which carbon dioxide is introduced into the paste directly or via an aqueous vehicle prior to the addition of chemical additives so as to control the ionic demand and the zeta potential downstream, and especially at the step of adding the additives.In particular, the additives are added to the mixing vat (2), and the carbon is added to the white water at the exit of the broken pulper (15) or in the short circuit (9). / P
