| 摘 要： | 优选助剂组合ZW-1/抗坏血酸/次亚磷酸钠处理黑杨APMP纸浆取得了令人满意的光稳定效果.用紫外光辐照、干/湿热老化处理,作者对组合中各助剂优化用量以及助剂组合处理改善黑杨APMP纸浆光稳定性能的机理进行了研究.结果表明,组合中各助剂优化用量分别为0.25%,0.5%,1.0%;助剂组合处理能够有效改善黑杨APMP纸浆光稳定性能,是因为减少了模拟光老化过程中芳核羧基的含量.

| Abstract: | The optimized dosage of the additives and the mechanism of improvement on the brightness stabilization of poplar APMP pulp were investigated by means of combination of additive treatment (ZW|1/ascorbic acid/sodium hypo|phosphite).The combination of additives with optimized dosage was able to enhance the pulp's photo|stabilization substantially and was more efficient than the others. The optimized dosages of the additives were 0 25%,0.5%,1.0%. The decreases of aromatic carbonyl group made the brightness stabilization of the pulp better. |
