摘要
竹材及其制品在使用过程中易受到多种因素的影响发生劣化现象,导致性能降低和使用寿命缩短.目前,针对竹材老化、霉变、腐朽等方面的研究已取得了一定的成果.然而,有关竹材在多种劣化因子共同作用下的性能劣化及其劣化机理研究较少.文中综述了竹材在紫外光、湿热劣化因子、微生物作用下发生光老化、湿热老化、霉变、腐朽过程中的物理力学性能、微观构造和化学成分等变化,并对不同劣化形式之间的相互影响作用进行分析,进而提出竹材劣化的未来研究方向,以期为竹材的保护与利用研究提供理论参考.
Abstract
Bamboo and its products are susceptible to deterioration caused by a variety of factors during application,resulting in reduced performance and shortened service life.At present,the research on aging,mildew,and decay of bamboo has made certain achievements.However,the deterioration of bamboo properties and degradation mechanism under the combined effect of multiple deterioration factors are less studied.In this paper,the changes of bamboo timber in physical and mechanical properties,chemical composition,and microstructural of bamboo during the process of photoaging,moisture-heat aging,mildew,and decay are reviewed,and the interactions between the different forms of deterioration are elaborated.On this basis,the future research and development direction of the bamboo deterioration is proposed,in order to provide a theoretical reference for the conservation and utilization of bamboo.
