Abstract

UN METODO PARA PRODUCIR PULPA DE ALTO RENDIMIENTO MEJORADA DEL TIPO QUIMIOMECANICO O QUIMIOTERMOMECANICO. ES PRODUCIDA DESFIBRANDO O REFINANDO TROZOS, TAMIZANDO Y DIVIDIENDO LA PULPA TAMIZADA EN FRACCIONES DE COMPOSICION DE FIBRA MUTUAMENTE DIFERENTES. LA PULPA DESFIBRADA O REFINADA ES DIVIDIDA EN UNOS PRIMEROS MEDIOS DE TAMIZADO RETIRANDO AL MENOS UN 30% EN PESO DE LA SUSPENSION DE FIBRA ENTRANTE COMO UNA PRIMERA FRACCION DE FIBRA LARGA Y UNA PRIMERA FRACCION DE FIBRA FINA, SIENDO ESTA ULTIMA DIVIDIDA EN UNOS SEGUNDOS MEDIOS DE TAMIZADO EN UNA SEGUNDA FRACCION DE FIBRA LARGA, LA CUAL ES COMBINADA CON LA PRIMERA FRACCION DE FIBRA LARGA PARA FORMAR UNA FRACCION DE FIBRA LARGA DE PROPIEDADES MEJORADAS, QUE ES RETIRADA DEL PROCESO, UNA SEGUNDA FRACCION DE FIBRA FINA DE PROPIEDADES MEJORADAS, QUE ES TAMBIEN RETIRADA DEL PROCESO.
