Abstract

SE PRESENTA UNA PULPA QUIMIOMECANICA PARA SU USO EN LA MANUFACTURA DE PAPEL O DE PRODUCTOS DE CARTON EN DONDE SE DESEA UNA PULPA VOLUMINOSA CON ALTA CAPACIDAD PARA SER COLADA. LA PULPA TIENE UN GRAN CONTENIDO EN FIBRA DE ENTRE UN 60% Y UN 75%, UN CONTENIDO DE MATERIALES FINOS DE AL MENOS EL 14%, UN CONTENIDO DE FRAGMENTOS DE FIBRA POR DEBAJO DEL 0.05%, SE REFINA HASTA UNA LIBERTAD DE 600 ML CSF COMO MINIMO, Y TIENE UN INDICE TENSIONAL DE AL MENOS 10 KNM/KG. UN METODO PARA PRODUCIR LA PULPA COMPRENDE: A) LA IMPREGNACION DE ASTILLAS CON UN AGENTE QUIMICO REBLANDECEDOR DE LA LIGNINA; B) EL PRECALENTAMIENTO DE LAS ASTILLAS; C) EL REFINAMIENTO DE LAS ASTILLAS HASTA OBTENER PULPA PARA LA MANUFACTURACION DE PAPEL; EN DONDE LAS ASTILLAS SE IMPREGNAN Y SE CALIENTAN A LO LARGO DE UN PERIODO TOTAL DE AL MENOS CUATRO MINUTOS; A) UTILIZANDO UN LIQUIDO DE IMPREGNACION CALIENTE QUE TIENE UNA TEMPERATURA DE AL MENOS 130 (GRADOS) C; B) PRECALENTANDO LAS ASTILLAS HASTA UNA TEMPERATURA POR ENCIMA DE LA TEMPERATURA DE REBLANDECIMIENTO DE LA LIGNINA; C) REFINANDO LA PULPA EN UNA O MAS ETAPAS, DE LAS CUALES LA PRIMERA O UNICA ETAPA SE LLEVA A CABO SOLAMENTE A ESENCIALMENTE LA MISMA PRESION Y LA MISMA TEMPERATURA QUE EL PROCESO DE PRECALENTAMIENTO; Y REFINANDO LA PULPA CON UNA INTRODUCCION TOTAL DE ENERGIA QUE ES AL MENOS UN 50% Y COMO MAXIMO UN 90% DE LA INTRODUCCION DE ENERGIA REQUERIDA PARA CONSEGUIR EL MISMO CONTENIDO EN FRAGMENTOS DE FIBRAS QUE CUANDO SE PRECALIENTA A 135 (GRADOS) C Y SE UTILIZA LA MISMA MAQUINARIA.
