Abstract

EL COLOR SE ELIMINA DE LA PASTA DE MADERA SECUNDARIA CON AGENTES DE BLANQUEADO NO BASADOS EN CLORO EN SECUENCIAS DE TRATAMIENTO UTILIZANDO OXIGENO CON COMBINACIONES DE PEROXIDO, OZONO Y/O HIDROSULFITO EN CONDICIONES DE PH CONTROLADAS. EL TRATAMIENTO ACIDO ANTERIOR A LAS FASES DE BLANQUEADO MEJORA LA ELIMINACION DEL COLOR Y PROTEGE A LAS FIBRAS DE DAÑOS EN CONDICIONES DE BLANQUEADO MAS SEVERAS.
