Abstract
In this study, a modification combining densification and heat treatment of poplar wood (Populus tomentosa Carr.) was carried out, and the machining properties of theunmodified poplar wood (control) and the heat treated densified wood (HTD)were tested and evaluated. Inaddition, the water-based UV paint was covered on the control and HTD respectively, and thesurface coating properties of them were evaluated. The results showed that: (1)Themachining properties of poplar wood were improved after theheat treatment-densification modification. The score of comprehensive machining properties of the HTD was 45 (excellent grade), while the score of the control was 36 (good grade). (2)The abrasion resistance, hydrophobicity and adhesion were improved after heat treatment-densification modification. Therefore, the modification combining densification and heat treatment played asignificant role in enhancing thevalue of wood.
