Abstract

"PROCESSO PARA FABRICAçãO DE PAPEL". A invenção refere-se a um processo para fabricação papel, em que uma carga é pré-tratada e feita em suspensão para formar uma pasta aquosa, a pasta aquosa obtida é combinada com uma suspensão aquosa que contém fibras de celulose para formar uma solução de reserva, a solução de reserva obtida é tratada ao menos com um agente catiónico de retenção e a solução de reserva tratada é filtrada para formar papel. As propriedades de retenção e propriedades ópticas são aumentadas por meio de um tratamento da carga através de partículas coloidais inorgânicas que apresentam uma dimensão média inferior a 100 nm.
