Abstract
PROCESSO PARA FABRICAÇÃO DE UMA TRAMA DE FIBRA. A presente invenção refere-se a um processo para fabricação de uma trama de fibra, tal como papel, papelão, tecido ou semelhantes. No processo, fibras contendo celulose alvejadas são suspensas em água processada, de modo a preparar um estoque de fibras, que compreende peróxido de hidrogênio residual. O processo compreende pelo menos uma torre de estocagem de polpa através da qual o estoque de fibras é transferido antes de ser formado em uma trama fibrosa e secado. Íons de zinco são introduzidos no estoque de fibras ou em um de seus constituintes para manter a quantidade de peróxido de hidrogênio residual no estoque de fibras em, ou acima de, um nível limite predeterminado após pelo menos uma torre de estocagem de polpa.
