摘要
Efficient use of timber is a vital concern problem, especially in these regions where the forestry coverage ratio is decreasing. Studies on physical modification of wood have been taken more attention due to the increasing attentions on environmental protection. Thermal modification is emphasized and developed quickly in developing countries, especially in European countries. A large number of researches have been conducted and some industrial production plants have been built. This paper reviewed the history of heat treatment, exemplifies the industrial developments in several European countries, summarized the basic principle of heat treatment and describes the environmental characteristics. The properties of heat-treated wood and its usage are also summed up.
有效的利用木材资源是一个令人们关注的重要课题,尤其是在森林覆盖率低的国家。由于环保意识的增强,人们对木材的功能性改良越来越多地侧重于采用物理处理方法。在这样的背景下,木材热处理在许多发达国家迅速的蓬勃发展起来,尤其是在欧洲。欧洲许多国家的科研机构和生产企业都进行了大量的研究,一些大的木材热处理厂也相继建立。本文回顾了木材热处理技术的发展历程,列举了热处理木材在以荷兰、德国、法国和芬兰为代表的欧洲国家中的工业化现状,总结了热处理材性能改善的原因、环境特性以及性能和用途。图2参26。
