杨木质地软、强度低、密度小、体积稳定性和加工工艺性差。用低分子量酚醛树脂对杨木板材进行浸渍处理,不仅改善了木材的稳定性,提高了强度,而且由于表面的比重增大,使其耐磨性能以及硬度等物理性能有很大提高,为低质材的高效利用开拓了新的途径。1树脂的合成与浸渍处理1·1低? Poplar wood soft, low strength, low density, volume stability and processing technology is poor. Impregnation of poplar wood with low molecular weight phenolic resin not only improves the stability of wood and enhances the strength, but also increases the physical properties such as wear resistance and hardness due to the increase of surface specific gravity, which is low The efficient use of quality materials has opened up new avenues. 1 resin synthesis and impregnation treatment 1.1 low?
