Title
(PT) MÉTODO PARA COLAGEM DE UM PRODUTO DE PAPEL E PAPEL
Abstract
(PT)
MÉTODO PARA COLAGEM DE UM PRODUTO DE PAPEL E PAPEL. A invenção se refere a um método para colagem de um produto de papel que envolve as etapas de (a) fornecimento de um sistema de estoque de papel; (b) formação, na ausência de altas forças de cisalhamento, de uma emulsão aquosa de colagem compreendendo um componente de anidrido alquenil-succínico; (c) sujeição da emulsão formada da etapa (b) a uma etapa de pós-diluição na presença de um componente catiônico sob condições, na ausência de altas forças de cisalhamento, que produzem uma emulsão pós-diluída tendo eficácia aperfeiçoada de colagem; (d) adição da emulsão pós-diluída ao estoque de papel; e (e) formação de uma trama de papel.
