Glycerin Pretreatment Effect on Heat-treated Wood Dimensional Stability
Poplar(Populus tomentosa) and spruce(Picea asperata) samples were pretreated by soaking them in a glycerin solution before further heat treatment.Density increasing rate,moisture content,moisture adsorption antiswelling efficiency(ASE),and water absorption ASE of the treated wood samples were measured.The results showed that after glycerin pretreatment the sample’s density increasing rate increased,their equilibrium moisture content first decreased but then increased,and both moisture adsorption and water absorption ASEs also increased.
