摘要
研究了烧碱蒽醌法苇浆、碱性亚钠法苇浆、KP法针叶木浆在回用过程中纤维保水值、纤维聚戊糖含量以及成纸性能的变化,结果表明纸浆在回用中打浆前后聚戊糖含量稍有下降,而保水值增加;随着回用次数的增加,聚戊糖含量变化不大,但保水值却大幅度下降;成纸性能在回用中逐渐下降,而光学性能则向良好的方向发展。
The effect of hemi-cellulose content on fiber horrification and paper performance in recycling is studied concerning soda-AQ reed pulp, SP reed pulp and KP soft wood pulp. The result showed that slightly reduce in hemi-cellulose and increase in water-retention value had been seen after beating, while in the meantime, not hemi-cellulose but water-retention value decrease in a great degree with the increase in recycle time, and physical performance of paper draw clown gradually, but the optical performance became better.
