本文研究了两种新型干强剂，通过在不同介质中用醚化剂对半纤维素进行化学改性而制备，用于再生纤维基包装纸和旧瓦楞纸箱（OCC）纸浆中的应用。一种新型干强剂具有阳离子基团，而另一种则具有阴离子基团。结果发现，这些具有不同DS（取代度）值的新型干燥剂可以明显提高OCC纸浆的纸张强度。在OCC浆中添加1.0%（w/w）DS值为0.5的阳离子型半纤维素衍生物后，物性改善达到最大：断裂长度、耐破指数、撕裂指数和环压指数分别提高27.3%、51.6%、18.5%和68.4%。因此，半纤维素可用作造纸工业湿部添加剂生产的原材料。
This paper investigated the two novel dry strength agents, prepared by chemical modification of hemicelluloses with etherifying agents in different media, for application in recycled fiber based packaging paper and old corrugated container (OCC) pulp. One new dry strength agent possessed cationic groups, whereas the other had anionic groups. It was found that these new dry agents with different DS (degree of substitution) values could clearly improve paper strength of OCC pulp. With the addition of 1.0% (w/w) cationic type hemicellulosic derivatives with a DS value of 0.5 to OCC pulp, the physical property improvement reached its maximum: the breaking length, burst index, tear index and ring crush index increased by 27.3%, 51.6%, 18.5% and 68.4%, respectively. Hemicelluloses could, therefore, be used as source material for the production of wet-end additives in the paper industry.
