Heat treatment is often used to improve the dimensional stability of wood. In this study, the effects of heat treatment on technological properties of Red-bud maple (Acer trautvetteri Medw.) wood were examined. Samples obtained from Düzce Forest Enterprises, Turkey, were subjected to heat treatment at varying temperatures (120 degrees C, 150 degrees C and 180 degrees C) and for varying durations (2h, 6h and 10h). The technological properties of heat-treated wood samples and control samples were tested. Compression strength parallel to grain, bending strength, modulus of elasticity in bending, janka-hardness, impact bending strength, and tension strength perpendicular to grain were determined. The results showed that technological strength values decreased with increasing treatment temperature and treatment times. Red-bud maple wood could be utilized by using proper heat treatment techniques with minimal losses in strength values in areas where working, and stability such as in window frames, are important factors.
热处理常用于提高木材的尺寸稳定性。在本研究中，考察了热处理对红芽槭（Acer trautvetteri Medw.）木材工艺性能的影响。从土耳其杜兹森林企业获取的样品在不同温度（120℃、150℃和180℃）和不同时长（2小时、6小时和10小时）下进行热处理。对热处理木材样品和对照样品的工艺性能进行了测试。测定了顺纹抗压强度、抗弯强度、抗弯弹性模量、詹卡硬度、冲击抗弯强度和横纹抗拉强度。结果表明，工艺强度值随处理温度和处理时间的增加而降低。在诸如窗框等加工和稳定性很重要的领域，通过采用适当的热处理技术，红芽槭木材在强度值损失最小的情况下仍可得到利用。
