自由基与纸浆漂白(Ⅱ)——自由基的控制和碳水化合物的保护

Radicals and Pulp Bleaching (Ⅱ)——Radical Management and Carbohydrate Protection

介绍预处理降低未漂浆中的过渡金属离子含量和在漂白过程中添加助剂控制自由基、保护碳水化合物的途径 ,以便达到提高漂白选择性 ,改善漂白效果 ,降低漂白废水污染等目的 .

This paper commends on the measures to decrease the transition metal ions in unbleached pulp by means of pretreatment prior to bleaching, to manage radicals and protecting carbohydrate with the addition of chemical agents during bleaching. In this way we can gain an obvious improvement in bleaching selectivity, in bleaching efficiency and in minimizing effluent pollution from bleaching mill.
