木材微观结构分析方法与特征参数
Analysis methods and characteristic parameters of wood microstructure
摘要
Abstract
Wood is a multi-scale and highly anisotropic natural polymer material,which consists of cellulose,hemicellulose,lignin and other components of a complex three-dimensional network structure.These structures are the key factors affecting micro-macroscopic physical and mechanical properties of wood,and the microstructure and main characteristic parameters of wood are of great significance to the understanding of properties of wood as well as wood modification and processing and utilization.This paper comprehensively analyzes the methods of wood microstructure analysis and summarizes its main characteristic parameters.In terms of analytical methods,microscopic observation,X-ray radiography and diffraction analysis,computed tomography and other technologies were widely used,combined with data acquisition and two-dimensional and three-dimensional imaging methods,can reconstruct wood microstructural models,measure microstructural parameters,and reconstructed structural models revealed clearer micro-morphological features.The microstructural parameters of wood mainly include cellular structure parameters,porosity,cellulose microfilaments and other parameters of wood.At present,the observation and study of microstructure is mostly limited to the micron scale,and the analysis of nanoscale and smaller molecular scale structure is mainly based on theoretical simulation,and the structural analysis methods that can be directly observed and characterized need to be further studied in depth.关键词
