三种速生针叶材制浆性能的比较

Comparison of Pulpabilities between Three Kinds of Fast Growing Needle Leave Wood

对三种速生针叶材的制浆性能进行了比较，结果表明，它们的化学组成没有明显差别，硫酸盐法蒸煮可漂化学浆的合适用碱量为１７％ （Ｎａ２Ｏ 计） ，ＡＳＡＱ 半化浆的制浆性能基本相同，ＳＣＭＰ 化机浆的化学预处理效果无显著差别。综合评价和比较，马尾松的纸浆强度较高，火炬松次之，湿地松较差。

The pulpabilities of three kinds of fast growing needle wood were compared.The results show that their main chemical compositions are similar .The suitable alkali charge is 17%(based on Na2O)for pulping bleachable sulfate pulps.The pulpabilities of AS-AQ semi-chemical pulps are almost the same.The results of chemical pretreatment for SCMP do not have obvious differences.By comprehensive evaluation and comparison, the strengths of pulp made from Masson's pine are higher,those from Loblolly pine come second,and those from Cluster pine are relatively poor.
