Abstract

LA INVENCION SE REFIERE A UN METODO RELATIVO AL BLANQUEO DE FIBRAS SECUNDARIAS. EL BLANQUEO DE FIBRAS SECUNDARIAS CONSISTE EN UNA ETAPA DE REFINADO EN LA QUE SE TRABAJA MECANICAMENTE LA PASTA EN UN APARATO DE TRATAMIENTO DE PASTA (1) Y UNA ETAPA DE BLANQUEO QUE SE LLEVA A CABO EN UNA TORRE DE BLANQUEAMIENTO (8). EN LA ETAPA DE TRATAMIENTO MECANICO, QUE SE PUEDE LLEVAR A CABO EN UN DISPERSADOR DE DISCO, SE SUMINISTRA OXIGENO (12) A LA PASTA (1) A TRAVES DE UN TUBO DE ALIMENTACION DE OXIGENO (5), JUSTO EN EL CENTRO DEL APARATO, PARA DISPERSAR ASI EL OXIGENO DE MANERA UNIFORME Y BIEN POR TODA LAS PASTA (M). ESTA ALIMENTACION DE ENERGIA PERMITE MANTENER EL CONSUMO DE PEROXIDO A UN NIVEL MUY BAJO, O PERMITE CONSEGUIR UN BRILLO MUY ALTO.
