Abstract

LA INVENCION HACE REFERENCIA AL PROCEDIMIENTO DE OBTENCION DE UNA SUSPENSION HOMOGENEA DE CELULOSA EN UNA DISOLUCION ACUOSA DE UN OXIDO DE AMINA TERCIARIA, MEDIANTE EL CUAL LA CELULOSA SE MEZCLA CON LA DISOLUCION ACUOSA DE OXIDO DE AMINA TERCIARIA EN UN DISPOSITIVO DE MEZCLA QUE CONSTA DE UN DEPOSITO PARA RECOGER LA SUSPENSION Y UN INSTRUMENTO MEZCLADOR. EL PROCEDIMIENTO SE CARACTERIZA PORQUE SE UTILIZA UN MECANISMO EN EL QUE EL DEPOSITO ESTA EN ROTACION DURANTE EL PROCESO DE MEZCLA.
