| 摘 要： | 在蒸煮稻草的过程中,分别加入氧化铝、氧化镁、氧化钙,使其同溶出的硅发生反应生成某种物质留在纤维中,以减少黑液中硅质量分数,降低黑液黏度,消除或降低"硅干扰"。结果表明:加入3%～5%除硅剂后,黑液中硅质量分数降低,最大降幅达84.39%;黑液黏度最大下降幅度为16.7%,而纸浆中硅质量分数有大幅度提升。

| Abstract: | In this study,oxides such as Al2O3,MgO and CaO,were added to the cooking liquor of rice straw in soda-AQ pulping process,respectively.These oxides reacted with silicon to generate a kind of substance,which remained in the fibers;therefore,the content of silicon in the black liquor declined.Results showed that,in the soda-AQ pulping process,adding 3% to 5% oxides could significantly decrease the silicon content in straw black liquor,and the maximum decreasing amplitude reached 84.39%;black liquor viscosity almost decreased by 16.7%,and the silicon content in pulp also increased obviously. |
