Abstract

Various heat treatment methods are available today. In this study, accelerated weathering test performance of Scots pine (Pinus sylvestris L.) wood after heat treatment under oxygen (open system) and vacuum (closed system) was investigated. Samples were prepared from pine sapwood part with dimensions of 75 (Radial) × 15 (Tangent) × 150 (Fibers) mm. After the accelerated weathering test, the surface roughness and color measurement of the samples were carried out. According to the results obtained, the minimum color change was obtained after heat treatment performed in a closed system (VHT) at 190 °C. The surface roughness parameters of poplar samples that were heat treated in the closed system increased with the increase in the heat treatment temperature. In the heat treatment performed in the closed system, lower roughness values were obtained compared to the heat treatment performed in the open system (HT). In parallel with the increase in the accelerated weathering time, the total color change and roughness values increased.
