米级透明木单板的制备及性能
Preparation and Performance of Meter-Scale Transparent Wood Veneer
摘要
Abstract
Transparent wood is a new type of wood-based composites.The existing manufacturing technology can only prepare small-size samples,which was far below the requirement of industry scale application.In this study,birch(Betula sp.)veneer was used as raw material to prepare large-dimension decolorized wood veneer by bleaching treatment.Afterwards,the transparent wood with a length of 1 meter was prepared by impregnating epoxy resin under vacuum condiction.The results showed that the transparent wood has good light transmittance with the average light transmittance and haze of 76.7%and 81.4%,respectively.Because the epoxy resin was immersed in wood cells,the longitudinal and transverse tensile strengths of transparent wood were greater than those of original wood.Finally,the preparation process and cost of meter-scale transparent wood veneer were also analyzed.This study not only provided a reference for promoting the application of transparent wood in concealed spaces such as building patios,car skylights,offices,bathroom doors and windows,and partitions but also lays a theoretical foundation for the industry application of transparent wood.关键词
