Abstract

PARA FABRICAR UNA SOLUCION DE CELULOSA EN N-METILMORFOLINA-N-OXIDO Y AGUA, QUE, EN COMPARACION CON LAS SOLUCIONES CONOCIDAS, POSEA UN CONTENIDO EN AGUA MAYOR CON UN CONTENIDO EN CELULOSA DADO, SE SOMETE UNA MEZCLA DE LOS TRES COMPONENTES A TASAS DE CIZALLAMIENTO DE 400 A 3000 S ELEVADO -1, CON PREFERENCIA DE 500 A 800 S ELEVADO -1. CON ESTE PROCEDIMIENTO SE PUEDEN FABRICAR SOLUCIONES, QUE CUMPLEN LA SIGUIENTE CONDICION (C SUB CELL = CANTIDAD EN MASA DE CELULOSA; C SUB H2O = CANTIDAD EN MASA DE AGUA) C SUB CELL > 0, 3469 081 (RAIZ CUADRADA) 1,65 + 0,1 (100 C SUB H SUB 2O 2O.
