摘要
采用热脉冲法测定杨木定向结构板的热物理特性，研究板材的密度、含水率对其热物理特性的影响，获得了绝干、气干及高湿度状态下各种不同密度的定向结构板的热导率、热扩散率、比热容的变化规律，以此为建筑热工设计提供依据。通过对不同材料建筑物的采暖能耗的对比分析得出，定向结构板具有良好的保温隔热性能，用作墙体材料可达到节能目的。
Thermophysical properties of OSB was studied with heat flow method.Test specimens were preconditioned under oven dry, RH 50%, RH 80% and RH 90% before tested.Effects of boards density and moisture on the properties were discussed.It indicates that OSB tested had good thermal insulation performance compared with other traditional construction materials.
