Abstract

LA INVENCION SE REFIERE A LA DISPERSION DE FIBRAS BASADAS EN CELULOSA EN LA PAJA MEDIANTE LA AYUDA DE UN ALCALI Y UNA AGITACION MECANICA FUERTE. ESTO SOLUBILIZA EL PENTOSAN EN LA PAJA, Y CONVIERTE LA MEZCLA EN UNA PASTA DE ALTA VISCOSIDAD, DE MANERA QUE LAS FUERZAS DE LA AGITACION DESGARREN LA PAJA INDIVIDUAL Y TAMBIEN DISPERSEN LAS FIBRAS. DE ESTA FORMA LAS FIBRAS PUEDEN DISPERSARSE EN UN CONTENIDO SOLIDO DE HASTA UN 85% EN CONTRA DE SOLAMENTE EL 8% DE LOS METODOS TRADICIONALES. EL TRATAMIENTO DA COMO RESULTADO UNA PASTA DE MOLDEADO, Y ESTA PUEDE USARSE DIRECTAMENTE PARA LA FORMACION PLASTICA DE PRODUCTOS DE FIBRA BASADOS EN CELULOSA DESPUES DE SU NEUTRALIZACION.
