摘　　要：以稻草人纤浆本色浆为研究对象,利用硅在不同温度、pH值等条件下的溶出特性,组织正交试验探索最佳除硅工艺;根据次氯酸盐强氧化性脱木素原理,按照降低能耗、提高效率的原则,采用正交试验设计和综合平衡法分析实验结果得出最佳漂白方案;为进一步提高人纤浆的白度,在一段漂的基础上又进行了二段漂,研究结果表明:当碱预浸浆浓8%、用碱量为3%、温度为80℃、时间为30min,一段漂浆浓4%、用氯量为6%、温度为80℃、时间为30min,二段漂浆浓4%、用氯量为6%、温度为80℃、时间为20min时,漂白效果较好,浆料白度接近市售人纤浆质量标准。The paper takes straw pulp as the research object,and uses silicon in different temperature,pH and other conditions to find the optimal silicon removal technology.According to the principle of delignin,the optimal bleaching solution was obtained by using orthogonal test design and comprehensive balance method.In order to further improve the fiber pulp whiteness,on the basis of primary bleaching ran secondary bleaching,the results show that when the alkali presoak slurry concentration 8%,with a reduction of 3%,the temperature is 80℃,the time for 30 min,primary bleaching slurry concentration 4%,using chlorine content is 6%,the temperature is 80℃,time for 30 min,secondary bleaching slurry concentration 4%,with the chlorine content is 6%,the temperature is 80℃,time of 20 min,bleaching effect is good,pulp whiteness nearly sold people fiber pulp quality standards.
