摘　　要：为高效充分利用木材加工剩余物,研究以工厂单板加工剩余物为原材料制备人造板,考察其弹性模量、静曲强度、24 h吸水厚度膨胀率和剖面密度曲线分布情况。结果表明:所得板材的弹性模量为18439.6 MPa、静曲强度为206.5 MPa,24 h吸水厚度膨胀率为7.5%,优于国家标准中人造板的性能指标。剖面密度分布曲线影响板材弹性模量与静曲强度。In order to make full use of wood processing residues,the wood-based panels were prepared from veneer processing residues in factories,and the elastic modulus,static bending strength,24 h water absorption thickness expansion rate and profile density curve distribution are investigated.The results showed that the elastic modulus of the obtained panels was 18439.6 MPa,the static bending strength was 206.5 MPa,and the thickness expansion rate of 24 h water absorption is 7.5%,which was better than the specified value for the performance of wood-based panels in the national standard.The profile density distribution curve affects the elastic modulus and static bending strength of the sheet.
