Abstract

"PRODUTOS CELULóSICOS CONTENDO PERCENTUAL APERFEIçOADO DE CARGA DE CARBONATO DE CáLCIO NA PRESENçA DE OUTROS ADITIVOS PARA PRODUçãO DE PAPEL". A presente invenção refere-se a produtos celulósicos compreendendo fibras celulósicas e carbonato de cálcio precipitado, preparado "in situ" durante a produção de papel. O carbonato de cálcio precipitado é depositado nas fibras celulósicas e está presente em vários tamanhos, formas e morfologias, e está presente nos produtos celulósicos em todas as características físicas das fibras celulósicas. Pelo menos uma parte do carbonato de cálcio precipitado está presente com a fibra, com base na interação com uma ou mais substâncias químicas usadas na produção de papel."CELLULIC PRODUCTS CONTAINING PERFECT PERCENTAGE OF CALCIUM CARBONATE LOAD IN THE PRESENCE OF OTHER PAPER PRODUCTION ADDITIVES". The present invention relates to cellulosic products comprising cellulosic fibers and precipitated calcium carbonate prepared in situ during papermaking. Precipitated calcium carbonate is deposited in cellulosic fibers and is present in various sizes, shapes and morphologies, and is present in cellulosic products in all physical characteristics of cellulosic fibers. At least part of the precipitated calcium carbonate is present with the fiber based on the interaction with one or more chemicals used in papermaking.
