摘要
以H2O2 漂白后的混合办公废纸脱墨浆为待漂浆, 系统地研究了各种因素对保险粉(连二亚硫酸钠)漂白过程的影响。结果表明, 在经优化的实验条件下, 保险粉漂白该浆种效果良好, 可提高白度7% 以上。
Sodium dithionite was used as a bleaching agent in the second stage bleaching of mixed office waste paper deinked pulp,which has been bleached with H 2O 2 in the first stage.Several parameters in sodium dithionite bleaching process were studied systematically.The results showed that sodium dithionite was effective in bleaching this kind of pulp and 7 points of ISO brightness gain were achieved under the optimum conditions.
