对杨木硫酸盐浆HP漂白进行了研究。实验结果表明,使用HP两段漂白,当用氯量为4%时,漂浆白度达到65.35%ISO,白度增值为32.84%ISO,再用3%的H2O2进行漂白,纸浆的白度可达到76.42%ISO,pc值为0.78,抗张指数为21.9N·m/g,撕裂指数为4.8mN·m2/g。
Poplar kraft pulp HP bleaching was studied. The experimental results showed that the bleaching of HP pulp was 65.35% ISO with the whiteness of 32.84% ISO and the bleaching of pulp with 3% H2O2 when the chlorine content was 4% Reached 76.42% ISO with a pc value of 0.78, a tensile index of 21.9 N · m / g and a tear index of 4.8 mN · m2 / g.
