摘要
木材浸渍改性能够显著提升木材的尺寸稳定性、力学强度、耐久性等性能,扩展其应用领域。然而,浸渍改性材的高含水率和改性剂引入使其干燥过程面临诸多挑战,如产生干燥不均匀、开裂、变形等问题。综述了浸渍改性方法对木材性质的影响,以及浸渍改性木材干燥工艺的研究进展,分别探讨了热固性树脂、硅系化合物及其他改性剂的浸渍效果及其对木材性能的影响,并重点分析了浸渍改性材常规干燥、高温干燥、过热蒸汽干燥等不同干燥工艺的优缺点。最后,展望了未来浸渍改性材干燥工艺的发展趋势,包括非传统干燥方法的应用、干燥工艺的组合化、干燥过程的优化以及干燥模型的建立。今后研究应注重环保、能效和干燥质量的综合提升,以促进浸渍改性木材的工业化生产和可持续发展。
Wood impregnation modification significantly improves the dimensional stability,mechanical strength,durability,and other properties of wood,and expands its application field.However,the high moisture content of the impregnation-modified wood and the introduction of modifiers make the drying process face many challenges,such as uneven drying,cracking,deformation,and so on.In this paper,the effect of impregnation modification on the properties of wood and the research development of drying process of impregnation-modified wood were reviewed.The impregnation effects of thermosetting resins,silicon compounds,and other modifiers and their effects on wood properties were discussed.The advantages and disadvantages of different drying processes such as conventional drying,high temperature drying,and superheated steam drying of impregnationmodified wood were analyzed.Finally,the development trend of impregnation-modified wood drying process in the future was prospected,including the application of non-traditional drying methods,the combination of drying process,the optimization of drying process,and the establishment of drying model.Future research should focus on the comprehensive improvement of environmental protection,energy efficiency,and drying quality,so as to promote the industrial production and sustainable development of impregnation-modified wood.
