Abstract

PROCESSO PARA PRODUçãO DE PAPEL. A presente invenção se refere a um processo para produção de papel, cujo processo compreende: (i) prover uma suspensão aquosa compreendendo fibras celulósicas; (ii) adicionar à suspensão, em busca de todos os pontos de alto nível de cisalhamento: um primeiro polímero, que é um polímero catiónico tendo uma densidade de carga acima de 2,5 meq/g; um segundo polímero; e um terceiro polímero, que é um polímero aniónico orgânico ou inorgânico; e (iii) desidratação da suspensão obtida para formar o papel.PAPER PRODUCTION PROCESS. The present invention relates to a papermaking process which process comprises: (i) providing an aqueous suspension comprising cellulosic fibers; (ii) adding to the suspension for all high shear points: a first polymer, which is a cationic polymer having a charge density above 2.5 meq / g; a second polymer; and a third polymer, which is an anionic organic or inorganic polymer; and (iii) dehydrating the suspension obtained to form the paper.
