Abstract

"PROCESSO PARA PRODUçãO DE POLPA PARA PAPEL DE IMPRENSA MELHORADA PARA A QUALIDADE SC/LWC". A presente invenção é relativa a um processo para produção de TMP melhorado para qualidades SC/LWC. A polpa para papel de imprensa é bombeada para um refinador LC 1 no qual o comprimento médio de fibra é reduzido e é então transferida para uma peneira primária 2 na qual a polpa é dividida em um aceite primário e um rejeito primário com a ajuda de uma cesta peneira fendilhada que tem uma largura de fenda estreita. O aceite primário é transferido para a linha principal onde o rejeito primário é desidratado e então refinado em um refinado HC 3. O rejeito primário refinado é então transferido para uma peneira secundária 4 na qual o rejeito é dividido em um aceite secundário e um rejeito secundário com o auxílio de uma cesta peneira fendilhada que tem uma largura de fenda estreita. O aceite secundário é retornado para a linha principal e misturado com o aceite primário a partir da peneira primária.
