【摘要】 对白蜡木、柞木、香樟、荷木等实木地板坯料进行了超高温热处理的研究。结果表明:与普通实木地板相比,热处理实木地板后吸湿性降低51.87%,尺寸稳定性提高42.36%,弦向弹性模量和顺纹抗压强度分别提高了1.15%和2.19%,(但弦向抗弯强度明显降低),导热效能超过实木复合地板。该技术已在工业上推广应用。更多还原

【Abstract】 White ash(Fraxinus chinensis),Mongolian oak(Quercus mongolica),Camphor wood(Cinnamomum camphora),Chinese gugertree(Schima superba) blanks of solid-wood flooring were heat-treated with super-high temperature.The technology was applied in a wood factory in Nanxun,Zhejiang Province based on laboratory experiments.Compared with the common solid wood flooring,moisture adsorption of heat-treated wood decreased by 51.87% and dimensional stability increased by 42.36%.Also,tangential modulus of elasticity and longitudinal compression strength increased by 1.15% and 2.19% respectively,but tangential bending strength reduced substantially.Heat-conduction ability was better than untreated solid-wood flooring used as ground heating flooring.更多还原
