摘 要：
【目的】人工林马尾松木材易蓝变、含有松脂、尺寸稳定性和耐久性差,为了改善其缺陷,提高其使用范围和产品附加值。【方法】本研究采用单因素方差分析法及定量分析法,主要研究了热处理温度对处理材颜色、物理力学性能和FTIR性能的影响。【实验结果】实验结果表明:热处理时间为8h,热处理温度为165℃、175℃、185℃、195℃时,与未处理材相比,ΔL值分别下降了3.69、4.36、10.23和11.66,静曲强度分别下降了3.05%、10.06%、13.27%和16.79%,弹性模量分别下降了9.99%、11.45%、14.63%和16.72%;FTIR图羟基吸收峰的强度明显降低,羰基吸收峰的强度略呈降低趋势,其尺寸稳定性明显高于未处理材。【结论】对人工林马尾松木进行热处理,能提高其尺寸稳定性,深度脱脂及防蓝变。

摘 要：
【Objective】Pinus massoniana plantation is prone to blue satin with rosin,poor dimensional stability and weak durability,therefore it becomes a desirable aim to resolve its deficiencies and improve application & added value of products. 【Method】The research employs one-way analysis of variance method and quantitative analysis method to study influences of heat treatment's temperature to wood color,mechanical property,and FTIR,respectively. 【Experimental Result】Experimental result shows: when heat treatment lasts eight hours and heat treatment's temperatures are 165℃,175℃,185℃,195℃,their ΔL decreases by 3. 69,4. 36,10. 23 and 11. 66,respectively; their static bending strength decreases by3. 05%,10. 06%,13. 27% and 16. 79%,respectively; their elastic modulus decreases by 9. 99%,11. 45%,14. 63% and 16. 72%,respectively; absorption peak intensity of hydroxyl reduces significantly and that of carbonyl decreases slightly reflected by the FTIR; its dimensional stability is apparently better than untreated wood. 【Conclusion】Heat treatment on pinus massoniana plantation can improve its dimensional stability,help conduct deep degreasing and keep away from blue stain.
