不同温度热处理对木材耐久性的影响
The Effect of Different Temperature on the Durability of Heat-Treated Wood
摘要
Abstract
the wood of Larix spp.and Populus ussuriensis were heat-treated at different temperatures from 150℃to 210℃for 4 hours by biomass gas.Laboratory termite resistance test and field-buried durability test were con-ducted on the two kinds of heat-treated woods.Results showed that termite resistance of the woods decreased obvi-ously after heat treatment.Weight loss of the two heat-treated woods tends to increase according to the gradual in-crement of temperature.Temperature also has great influence on the natural durability of heat-treated woods.190℃and 180℃ were respectively the points of significant change for Larix spp.and Populus ussuriensis woods.Natural durability of Larix spp.wood was improved while that of Populus ussuriensis wood was deteriorated when they were heat-treated at a higher temperature.关键词
