摘要
通过实验研究了硫酸盐竹浆高温高压过氧化氢漂白工艺.实验结果表明:高温高压过氧化氢漂白在加入4%(质量分数,下同)的H2O2,H2O2/NaOH用量比为1.3,MgSO4用量为0.5%,Na2SiO3用量为3%,控制反应温度为120℃,保温时间为60min,氧压为1.2MPa,浆浓为10%的条件下,漂后浆料白度达79.5%ISO,卡伯值达2.5,粘度为719mL/g.
This study bamboo pulp as raw material, the high temperature and high pressure hydrogen peroxide bleaching process were studied. The experimental results show that： high temperature and high pressure hydrogen peroxide bleaching in joining 4% H2O2, H2O2/ NaOH use than 1.3, MgSO4 0.5% ,Na2 SiO3 3%, and control of the reaction temperature of 120℃, the holding time is 60 min, oxygen pressure of 1.2 MPa , plasma concentration of 10% of the conditions, after bleaching pulp brightness of 79.8% ISO, kappa value of 2： 5, viscosity of 719 mL/g.
