摘要
随着国家对造纸行业环保要求的提高,纸浆臭氧漂白的发展迎来了黄金时期。然而臭氧漂白的选择性较差,其反应条件和原材料的情况对最后纸浆的实际漂白效果影响较大。文章介绍了臭氧漂白的国内外研究现状,讨论了实验室和实际生产中,各因素对纸浆臭氧漂白效果的影响。
With the improvement of national environmental protection requirements for the paper industry,the development of pulp ozone bleaching has ushered in a golden period.However,the selectivity of ozone bleaching is poor,and its reaction conditions and raw material conditions have a great influence on the actual bleaching effect of the final pulp.The research status of ozone bleaching at home and abroad was introduced,and the influence of various factors on pulp bleaching effect in the laboratory and actual production was discussed.
