AVALIAÇÃO DAS PROPRIEDADES FÍSICO-MECÂNICAS DE POLPAS PRODUZIDAS POR NOVAS SEQUÊNCIAS DE BRANQUEAMENTO
The efficiency of oxygen delignification is very low for pulps of low number kappa and with high concentrations of hexenuronic acids, therefore the oxygen does not react with these acids, so being minimum the elimination of these during the oxygen delignification (pre-O2) in simple or double stage....
