摘要：探讨了过氧化氢(H2O2)漂白麦草化学机械浆的各种影响因素。优化后的工艺条件为:H2O26%(质量分数,下同),浆浓20%,MgSO40.05%,二乙烯三胺五乙酸(DTPA)0.3%,Na2SiO35.0%,NaOH3.5%,漂白温度80℃,漂白时间2.5h,白度可以达到53%(ISO),能够满足配抄普通文化用纸的要求。
Various impacting factors in the hydrogen peroxide bleaching of wheat straw chemomechanical pulp （CMP） were investigated. The optimized bleaching technology was as follows ： 6 % H2O2,20 % pulp consistence, 0.05 % MgSO4,0.3 % DTPA,5.0 % Na2SiO3,3.5 % NaOH, 80 ℃ bleaching temperature, 2.5 h bleaching time, with which the CMP brightness reached 53 % （ISO）. Based on the results obtained above, a new technology, i. e. ,enzymatic pretreatment followed by high consistence two-stage hydrogen peroxide bleaching was proposed so as to further improve CMP brightness, to increase its additional value, as well as to develop its application.
