有关制浆中木素的简单介绍

木素存在于维管束中，木材中含量达20％～30％。化学构造是以3种类苯丙烷为构成单位的复杂聚合的枝状构造。在天然情况下与纤维素和其它糖类结合在一起，充填在细胞壁的纤维素胶囊中，起着强固组织的作用。然而在制浆中我们在保留大部分纤维素和部分半纤维素的同时，还必须尽可能多的除去木素，因而我们对木素有必要进行些了解。

The Brief Introduction of the Lignin in the Pulp

The lignin exists in the vascular bundle and the content of it range from twenty percent to thirty percent. And its chemical structure is formed by three types of phenylpropane. In natural circumstances, cellulose and other sugars which fill in the capsule of cell wall combine together and strenthen the organization. However, in the cooking of pulp we have to obtain the most of the cellulose and part of the hemicellulose, and it is important for us to remove the lignin as much as possible.So we should get a better understanding for them.
