3种人工培育木材化学成分与纤维形态的研究

A Study on the Chemical Components and Fiber Morrhology of Three Cultivated Tree Species

对杨树 3 5 1 ,黑荆树和喜树木材的化学成分与纤维形态进行了测定及分析 ,旨在为其用于制造人造板及制浆提供必要的基础数据 .研究结果表明 :3种木材综纤维素含量高 ,纤维形态好 ,纤维长度大 ,长宽比高 ,壁腔比小于 1 ;分析认为 3种木材均是生产纸浆、纤维板、刨花板的优质原料 .

This paper reports the chemical components and the fiber morphology of three cultivated tree species in Yunnan.The obtained data can provide a reference for utilizing three types of wood in wood based panel and pulp. The results show that the three types of wood have high holocellulose,the fiber shapes well and longth.The ratio of fiber length to width is high,the ratio of cell-wall thickness to lumen diameter is less than 1.Based on these chemical components and fiber quality the authors have found that the three types of wood are kind raw material for pulp,particleboard and fiberboard.
