Abstract

"PROCESSO PARA MELHORAR O DESEMPENHO DE RETENçãO E DE DRENAGEM EM UM PROCESSO DE FABRICAçãO DE PAPEL" Um processo para melhorar o desempenho da retenção e da drenagem em um processo de fabricação de papel é divulgado. O processo compreende formar uma pasta aquosa, celulósica, de fabricação de papel, adicionando-se uma quantidade eficaz de um polímero de dispersão hidrofílica à pasta, drenar a pasta para formar uma folha e secar a folha. O polímero de dispersão hidrofílica é preferivelmente um copolímero de cloreto de dialildimetil amónio e acrilamida.
