Some Physical Properties of Heat-Treated Paulownia (Paulownia elongata) Wood

The aim of this study was to determine the changes in physical properties of Paulownia (Paulownia elongata) wood, a fast-growing species, during heat treatment at three different temperatures (160, 180, and 200°C) and durations (3, 5, and 7 h). After heat treatment, changes in swelling, density, col...

Description
Summary:The aim of this study was to determine the changes in physical properties of Paulownia (Paulownia elongata) wood, a fast-growing species, during heat treatment at three different temperatures (160, 180, and 200°C) and durations (3, 5, and 7 h). After heat treatment, changes in swelling, density, color, and equilibrium moisture content at 35, 65, and 85% RH were investigated. The results indicated that the minimum and maximum decrease swelling ratios were 6-46% for tangential, 4-32% for radial, and 12-64% for longitudinal. The equilibrium moisture contents were 1-26% for 35% RH, 1-33% for 65% RH, and 1-38% for 85 RH, respectively; the density of air-dried and oven-dried samples decreased by 1-16% and 1.5-15%, respectively, and color changes values (L*) were 10-40%.
