稻草浆强化氧碱漂白

介绍了AS AQ稻草浆通过酸预处理后 ,借助H2 O2 强化的氧碱漂白工艺。结果表明 ,经过一段氧漂 ,稻草浆的白度可以达到 6 5 .7%ISO ,粘度为 830mL/ g ,适合进行下段漂白 ,以达到较高的白度及较好的白度稳定性

Reinforced oxygen-alkali bleaching of AS-AQ straw pulp

This article describes the reinforced bleaching of AS AQ straw pulp by oxygen-alkali with H 2O 2,after acid pretreating. Experimental results show that the straw pulp could be bleached to 65.7% in ISO brightness and 830?mL/g in viscosity. It is fit to be processed in the next bleaching step to gain higher brightness and better brightness stability.
