不同树龄相思树混合木片硫酸盐法制浆

Kraft Pulping of Blended Acacia Species of Different Age

研究了在同一硫酸盐法蒸煮工艺条件下，大叶、马占和厚荚三种典型相思树不同树龄的木片混合蒸煮对浆料得率、硬度、强度性能和漂白性能的影响；比较了相思树混合木片硫酸盐ＡＱ法，硫化钠预处理硫酸盐法。

Three typical species of Acacia,i.e.A.mangium,A.auriculiformis and A.crassicarpa of 3,6 and 9 years old were blended in various proportions and cooked with different processes.The influence of blended proportions of different age wood species on pulp yield,hardness,strength and bleaching properties at the same kraft cooking condition was analyzed.The pulping results of kraftAQ,Na2S pretreated kraftAQ processes were compared with the conventional kraft process.
