Abstract

Patente de Invenção: <B>"FABRICAçãO DE PAPEL"<D>. Processo para a fabricação de papel em uma máquina de fabricação de papel compreendendo: fornecimento de uma suspensão de estoque celulósica fina; floculação da suspensão através da adição de uma solução aquosa de um auxiliar polimérico de retenção selecionado de polímero natural e sintético e, dessa forma, formando uma suspensão de floculação; cisalhamento da suspensão floculada; refloculação da suspensão que sofreu cisalhamento através da adição de uma suspensão aquosa de refloculação; drenagem da suspensão refloculada através de um fio a fim de formar uma folha; e secagem da folha caracterizado pelo fato de amido completamente cozido de modo substancial ser adicionado à suspensão após o cisalhamento e antes da drenagem.Invention Patent: <B> "PAPER MANUFACTURING" <D>. A process for making paper on a paper making machine comprising: providing a thin cellulosic stock suspension; flocculation of the suspension by adding an aqueous solution of a polymeric retention aid selected from natural and synthetic polymer and, thereby, forming a flocculation suspension; shear of the flocculated suspension; refloculation of the sheared suspension by adding an aqueous refloculation suspension; draining the reflocculated suspension through a wire to form a leaf; and drying the leaf characterized by the fact that substantially cooked starch is added to the suspension after shearing and before draining.
