| In this study, the effect of heat treatment on airdry density (D m), oven-dry density (D 0), shrinkage (β), swelling (α), compression strength parallel to grain (σ c//), bending strength (σ b), modulus of elasticity (MOE) in bending, brinell-hardness (H B), equilibrium moisture content (EMC), chemical content and cellulose crystallinity of oak (Quercus petraea Lieb.) wood were examined. Wood specimens were subjected to heat treatment under atmospheric pressure at three different air temperature (130, 180 and 230 C) and two different time levels (2 h and 8 h). The results showed that value of D m D 0 maximum moisture content (MMC), β, α, σ b, MOE, σ c//EMC and holocellulose ratio were decreased whereas the values of density in volume (D b), H B', lignin content, 1% NaOH and alcohol solubility values increased depending on the heating temperature and the time. The changes in cellulose crystallinity of the … |
