Abstract

"MéTODO PARA ADICIONAR UM ADITIVO QUìMICO PASSìVEL DE ADSORçãO A UMA PASTA DURANTE O PROCESSAMENTO DA PASTA E PRODUTOS FEITOS ATRAVéS DO REFERIDO MéTODO". As fibras em pasta podem ser tratadas com produtos químicos passíveis de adsorção com uma quantidade mínima de aditivos químicos não adsorvidos presentes mais tarde na água do processo de fabricação de papel. Um método para adicionar um produto químico passível de adsorção a uma pasta inclui misturar as fibras em pasta que nunca foram secas com água para formar uma mistura semifluida de fibras. Um aditivo químico passível de adsorção é adicionado à mistura semifluida de fibras. A mistura semifluida de fibras possuindo o aditivo químico passível de adsorção é transportada a um aparelho de formação de trama onde uma trama fibrosa úmida é formada. A trama fibrosa úmida pode ser secada a uma consistência predeterminada deste modo formando-se uma trama fibrosa seca possuindo entre cerca de 10 a cerca de 100% de retenção do aditivo químico passível de adsorção. A trama fibrosa seca é transportada a uma máquina de papel onde a trama fibrosa seca é misturada com água para formar uma mistura semifluida úmida. Em outras modalidades, a mistura semifluida de fibras pode ser processada para fornecer fibras grumosas ou fibras de cobertura úmidas. A mistura semifluida úmida contendo as fibras possuindo o aditivo químico passível de adsorção aderido a elas é transportada através da máquina de papel para formar um papel ou produto de papel acabado possuindo qualidade melhorada devido à retenção do aditivo químico passível de adsorção nas fibras em pasta.
