摘要:介绍了一种新型漂白剂在废纸浆生产箱纸板轻微漂白中的应用。通过实验室进行工艺优化，并进行中试生产。结果表明，使用该漂白剂在中性条件下处理废纸浆料,成纸亮度和L*值均得到提高,在漂白剂用量2.5 kg/t浆时,成纸L*值提高2.53个单位,且水处理负荷及生产成本增加不多。

Abstract:The application of a new type of bleaching agent used in slightly bleaching of OCC pulp was described in this paper. The application conditions of the agent and its bleaching effect was decided after the experiment in the laboratory. The results in the production showed that it could effectively improve the whiteness and the value of L*, while seldom increased the load of effluent treatment and the cost of production.
