摘要
简述了木质重组材料的起源与发展,主要对我国提出的新型纤维化单板高性能木质重组材料制造工艺具体环节的研究进展进行了综述。在原始木材碾压疏解阶段,随着疏解度的提高,木质重组材料的物理力学性能也随之增强。在纤维化单板改性阶段,改性处理提高了木质重组材料的防火、防霉性能,赋予了木质重组材料多功能性。总结了不同树种在浸胶阶段,浸胶方法和浸胶量对木质重组材料力学强度和功能性的差异。分析了组坯阶段的组坯方式和设备对木质重组材料强度及尺寸稳定性的影响。归纳了压制阶段中热压法和冷压热固化法两种压制方式各自的优势与不足。最终围绕木质重组材料的缺陷和现有的木质材料高附加值利用案例,针对提高木质重组材料的强度以及拓宽其应用提出了一些新设想。
This paper expounded the origin and development of wood scrimber,and our country proposed new type of fibrous veneer high-performance wood scrimber manufacturing technology specific links research progress was summarized.In the rolling and loosening stage of the raw wood,the physical and mechanical properties of the wood scrimber were enhanced with the increase of dispersion degree.In the fibrous veneer modification stage,the modified treatment improved the fire prevention and mildew resistance of the wood scrimber,giving the wood scrimber versatility.In the gumming stage,the differences in mechanical strength and function of wood scrimber of different tree species under different soaking method and impregnation amount were summarized.The influence of the paving method and equipment on the strength and dimensional stability of wood scrimber was analyzed.The advantages and disadvantages of hot pressing method and cold pressing as well as hot curing in the pressing stage are summarized.Finally,based on the defects of wood scrimber and the high value-added utilization cases of existing wood materials,some new ideas were raised improving the strength of wood scrimber and expanding their application.
