Improvement in 1995 for the manufacture of paper products by the object of the physicochemical - chemical behavior of the pate a paper

摘要

The present invention relates to a method of manufacture of paper from cellulose fibers dispersed in an aqueous medium, in which process the 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 and the zeta potential at the downstream direction, and in particular at the level of the step of the addition of additifs.en particular, the additives are added in the mixing chest (2), and of the carbon dioxide is added in the white water at the outlet from the pulper broken (15) or in the short circuit (9).
