Abstract

Wood of forest beech (Fagus sylvatica L.) has high physical and mechanical properties and is widely used in various industries. In this paper, it is shown that, when exposed to elevated temperatures, changes in the chemical composition of forest beech wood, disordering of bonds in the system of lignin and holocellulose, transformation of lignin, and decomposition of holocellulose caused mainly by the decomposition of part of hemicelluloses occur.

用红外傅里叶光谱研究热改性山毛榉木材的结构变化

摘要

森林山毛榉木（水青冈大号。）具有高的物理和机械性能，被广泛应用于各种行业。本文表明，暴露于高温下，森林山毛榉木材的化学组成发生变化，木质素和全纤维素系统中的键无序，木质素的转化，以及主要由木质素的分解引起的全纤维素的分解。半纤维素的一部分发生。
