| Abstract: | The compression deformation of the compressed poplar lumber was fixed by high temperature heat treatment.Then the effects of the method on the physical-mechanical properties of the poplar lumber were investigated respectively.The results showed that there were significant effects on the fixation of compressive deformation of poplar lumber.After compression and high temperature heat treatment,the density and dimension stability of the poplar lumber could be improved,the hygroscopicity was reduced,moreover,th... |
