速生杨木改性研究进展

论述了近年来杨木改性优化的研究进展。对速生杨木材进行优化处理可使其在性能上接近或超过天然林木材,这对充分利用速生杨木资源、缓解木材供应紧张局面、促进林业经济良性发展等具有重要意义。目前对杨木改性研究主要集中在依靠物质填充处理和非填充处理两方面,主要包括浸注有机物、无机物的改性处理,压密化处理,高温热处理以及多种方法联合改性处理等。

Research Progress in Modified Fast Growing Poplar Wood

The research progress in modified poplar wood optimization in recent years is stated and the optimal treatment of the insufficiency existing in fast growing poplar wood quality makes it approach or surpass the wood made of natural forests,which is of great importance for the full utilization of fast growing poplar wood resources,alleviation of the tension situation of wood supply and promotion of the sound development of forestry economy.Currently,the modification of poplar wood mainly concentrates on two aspects,i.e.dependence on material filling treatment and non-filling treatment,mainly including impregnation of organic matters,modified treatment of inorganic matters,compact treatment,high-temperature heat treatment and combined treatment with a number of methods.
