Abstract

LA INVENCION SE REFIERE A UN METODO PARA REDUCIR LA CANTIDAD DE SUSTANCIAS DE INTERFERENCIA EN LA CIRCULACION DEL AGUA DE PROCESOS QUE IMPLICAN SUSPENSIONES DE FIBRAS DE BASE DE MADERA, MEDIANTE LA FIJACION O UNION DE SUSTANCIAS DE ALTERACION A LAS FIBRAS, POR MEDIO DE ALMIDON CATIONICO. LA CANTIDAD DEL CITADO ALMIDON AÑADIDO A LA SUSPENSION DE FIBRAS ES APROXIMADAMENTE 0''04-0''5% DEL PESO EN SECO DE LAS FIBRAS.
