Abstract
PUEDE OBTENERSE UN BUEN DESTINTADO DE PAPEL DE DESECHO FORMANDO EN PRIMER LUGAR UNA PULPA CON UN PH ALGO, HACIENDO DESCENDER LUEGO EL PH, AÑADIENDO CELULOSA ALCALINA Y DEJANDO QUE LA CELULOSA ACTUE DURANTE UN PERIODO DE MACERACION CONTINUADO. EL DESTINTADO MEJORADO DA COMO RESULTADO UNA MAYOR BLANCURA Y UNA MEJOR LIMPIEZA (PARTICULAS DE TINTAS MENORES) EN EL PAPEL FABRICADO A PARTIR DE PULPA TRATADA DESPUES DE LA SEPARACION DE PARTICULAS DE TINTA. ESTE TRATAMIENTO DA COMO RESULTADO UN MEJOR FUNCIONAMIENTO DE CIERTOS EQUIPOS TALES COMO LOS TANQUES DE SEDIMENTACION Y UN MEJOR DRENAJE DE LA PULPA DURANTE LA FABRICACION DEL PAPEL.
