【摘要】 本文研究了落叶松制高白度化学浆的新工艺。采用氧-碱脱木质素和C/DE。D₁ED₂漂白程序,将卡伯值为28的落叶松硫酸盐法未漂浆漂到89.4％（SBD）,同时,探讨了氧-碱脱木质素过程中影响脱木质素的主要因素,测定了漂白浆的物理强度与漂白废水的特性。更多还原

【Abstract】 The new technology of the production of high brightness chemical pulp from larch were investigated in this paper. Larch kraft pulp of Kappa number 28 can be bleached to 89. 4% (SbD) brightness by using oxygen-alkali delignification and C/ DE0D1ED2 sequences. At the same time, the main parameters of affecting delignification were studied during the oxygen-alkali delignification, the physical strength of the bleached pulp and the properties of bleaching effluents were determined.更多还原
