摘要:

就目前国外常用的几种热处理工艺,分别对其工艺路线、工艺参数和其产品的性能及应用进行阐述。对比化学方法处理的浸渍材而言,热处理后的木材产品更加符合环保要求。采用热处理工艺来处理我国人工林木材,不但可以有效提高其尺寸稳定性、耐候性和防虫性等,而且还能拓宽人工林木材的使用领域。木材热处理将是我国木材工业未来发展的重要方向。

Abstract:

Heat treatment of wood is subjected to temperatures close to or above 200 ℃ for several hours in steam, nitrogen atmosphere with low oxygen content, water or oils. Several kinds of oversea methods for heat_treated wood are reviewed from processing procedures, treatment parameters, properties and application of final products respectively. Compared with the chemical modified wood heat-treated wood is much more environmentalfriendly. Thermal modification not only improves the dimensional stability, weathering resistance and biological resistance of plantation forest without any chemicals/biocides into the wood but also extends the applicative fields of plantation forest. Heat treatment of wood will play a very important role in Chinese wood industry in the future.

Key words: heat-treated wood, steam, nitrogen atmosphere, oil, properties of heat-treated wood, application, development
