摘要

热改性木材经过化学、物理和机械改性，导致对木材生物降解剂的抵抗力发生变化。本研究的目的是评估大桉、火炬松和柚木的工业工艺VAP-HolzSysteme®对香菇（褐腐病）和金菇（白腐病）的生物降解抗性，并分析其化学性质、全纤维素、木质素、总提取物和灰分的含量，生物降解前后。每个物种考虑了三种处理：天然对照木材、140°C和160°C下的改性木材。根据ASTM D 1413（ASTM，1994）制备试样，总共

BEHAVIOR OF THERMALLY MODIFIED WOOD TO BIODETERIORATION BY XYLOPHAGE FUNGI

Thermally modified wood undergoes chemical, physical, and mechanical modifications, resulting in changes in resistance to wood biodegrading agents. The objective of this study was to evaluate the resistance to biodeterioration of thermally modified wood by the industrial process VAP HolzSysteme ® of Eucalyptus grandis , Pinus taeda and Tectona grandis , submitted to the Lentinula edodes fungi (brown rot) and Pleurotus djamor fungi (white rot), and to analyze the chemical properties, contents of holocellulose, lignin, total extracts, and ash, before and after biodeterioration. Three treatments were considered for each species: Control - wood in natura , modified wood at 140 °C and 160 °C. The specimens were made according to ASTM D 1413 (ASTM, 1994), in a total of
