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."PROCESS TO IMPROVE RETENTION AND DRAINAGE PERFORMANCE IN A PAPER MANUFACTURING PROCESS" A process for improving retention and drainage performance in a papermaking process is disclosed. The process comprises forming a watery, cellulosic, paper-making paste by adding an effective amount of a hydrophilic dispersion polymer to the paste, draining the paste to form a sheet and drying the sheet. The hydrophilic dispersion polymer is preferably a copolymer of diallyldimethyl ammonium chloride and acrylamide.
