Heat treatment is often applied to wood species to improve their dimensional stability. This study examined the effect of heat treatment on certain mechanical properties of Scots pine (Pinus sylvestris L.), which has industrially high usage potential and large plantations in Turkey. Wood specimens obtained from Bolu, Turkey, were subjected to heat treatment under atmospheric pressure at varying temperatures (120, 150 and 180 degrees C) for varying durations (2, 6 and 10h). The test results of heat-treated Scots pine and control samples showed that technological properties including compression strength, bending strength, modulus of elasticity in bending, janka-hardness, impact bending strength and tension strength perpendicular to grain suffered with heat treatment, and increase in temperature and duration further diminished technological strength values of the wood specimens.
热处理通常应用于木材品种，以提高其尺寸稳定性。本研究考察了热处理对苏格兰松（Pinus sylvestris L.）某些力学性能的影响，该树种在土耳其具有很高的工业利用潜力且种植面积广大。从土耳其博卢获取的木材试样在常压下于不同温度（120、150和180摄氏度）和不同时长（2、6和10小时）进行热处理。热处理后的苏格兰松试样和对照样品的测试结果表明，包括抗压强度、抗弯强度、抗弯弹性模量、贾卡硬度、冲击抗弯强度和横纹抗拉强度在内的工艺性能会因热处理而受损，温度和时长的增加会进一步降低木材试样的工艺强度值。
