摘　　要：使用二氧化硫脲对旧瓦楞纸箱(OCC)浆料进行了轻度漂白;探讨了二氧化硫脲的用量、EDTA的用量、温度、浆料浓度及反应时间对漂白效果的影响。生产实践表明,二氧化硫脲对提高OCC浆料亮度具有较好的效果,是一种有效且极具竟争力的漂白剂。The slight bleaching of OCC pulp by thiourea dioxide was carried out. The effect of thiourea dioxide dosage, EDTA dosage, temperature, pulp consistency and reaction time on the lightness of thiourea dioxide treated pulp was studied. The experimental results indicate that thiourea dioxide is an effective and competitive bleaching agent, particularly for bleaching OCC pulp.
