FUNDAMENTALS OF PEROXIDE BLEACHING OF MECHANICAL PULPS
Some recent advances in the application of hydrogen peroxide in increasing the brighness of mechanical pulps are reviewed in this paper. In chemi-mechanical pulping, a new alkaline peroxide mechanical pulping process (PRC-APMP) has evolved from the conventional APMP process, with significant improvement in pulp properties. Related to hydrogen peroxide bleaching of mechanical pulps, new developments have been observed, such as the hydrosulfite-assisted chelation process (the Qy process), the Pm peroxide bleaching process, the Mg(OH)2-based peroxide process, the OBA- assisted peroxide bleaching process.
hydrogen peroxide bleaching mechanical pulp brightness new technology value added products.
