Efeito de reagentes de branqueamento nas propriedaes físicas e mecânicas da polpa de celulose Kraft de eucalipto

open access: yes, 2014
This study aims to evaluate the relation between the length of cellulose fibers and their influence on the refining, caused by different bleaching chemical reagents. The chemical reagents used in bleaching sequences affect significantly the composition of the pulp, causing depolymerization of cellulose chains, and by consequence, the reduction of fiber
