采用水溶性低分子量酚醛树脂固定大叶山杨（Ｐｏｐｕｌｕｓｄａｖｉｄｉａｎａｖａｒ．ｍａｃｒｏｐｈｙｌａ）和柳杉（Ｃｒｙｐｔｏｍｅｒｉａｆｏｒｔｕｎｅｉ）的木材压缩变形，制造表面压密材，并对其物理力学性能指标进行检测分析，结果如下：①随着树脂质量分数的增加，木材的增重率明显增加；②在冷水、热水恢复实验中，树脂质量分数小于５％，任一压缩率下的压缩变形都发生恢复，当树脂质量分数超过１０％时，压缩变形完全被固定；③随着压缩率的增加，表面压密材的硬度、顺纹抗压强度、弹性模量和静曲强度都明显增加，当压缩率一定时，树脂质量分数的变化对上述指标的影响不大
The water-soluble low molecular weight phenolic resin was used to fix the wood compressive deformation of Populus davidianavar.macrophyla and Cryptomeria fortunei, the surface compacted material was made and its physical and mechanical properties were tested and analyzed. The results are as follows: The resin weight fraction increased, the wood weight gain rate increased significantly; ② in the cold water, hot water recovery experiments, the resin mass fraction of less than 5%, the compression deformation under any compression rate are restored, when the resin mass fraction of more than 10% The compressive deformation is completely fixed; ③ With the increase of compressibility, the hardness, the compressive strength along compressive strength, the elastic modulus and the flexural strength of the surface compacted material all increase obviously. When the compression ratio is constant, the resin mass fraction Changes in the above indicators have little effect
