Abstract
PROCEDIMIENTO PARA MEJORAR LAS PROPIEDADES MECANICAS DE UNA PASTA DE PAPEL QUIMICA O SEMIQUIMICA DE BAGAZO, QUE CONTIENE AL MENOS UN 25% EN PESO DE MEDULA. CONSISTE EN SOMETER LA PASTA DE PAPEL QUIMICA O SEMIQUIMICA A UN TRATAMIENTO CON UN AGENTE OXIDANTE SELECCIONADO ENTRE LOS ACIDOS PERSULFURICOS Y SUS SALES. COMO AGENTE OXIDANTE SE UTILIZA EL ACIDO PEROXIMINOSULFURICO. UNA VEZ REALIZADO EL TRATAMIENTO CON EL AGENTE OXIDANTE, LA PASTA SE SOMETE A UN TRATAMIENTO CON CLORO EN MEDIO ACIDO. DE APLICACION EN LA FABRICACION DE PAPEL A PARTIR DE PASTAS QUIMICAS O SEMIQUIMICAS.
