木材的导热性以导热系数表示之,即在单位时间内(每秒),通过木材的单位面积(平方厘米)和单位长度(厘米),在木材两面间引起温度1℃的差异所需的热量。木材是多孔性物质,具有较小的导热系数值,可以作为隔热材料使用。木材的导热性与金属以及建筑材料中的砖、瓦、石灰、水泥、玻璃等相比是小的。因此,木材是良好的隔热材料之一。随着我国社会主义建设事业的迅速发展,木材作为隔热性材料的应用也将随之扩大。在钢铁厂,温度很高,用具有隔热性的木材和其它建筑材料一起,可以构成隔热性良好的建筑物。这对工人身休的健康起着有益的作用;在我国南方各省的民用建筑中,以及精密 The thermal conductivity of wood is expressed in terms of its thermal conductivity, which is the amount of heat required per unit of time (per second), per unit area (cm2) and unit length (centimeter) of wood, to cause a difference of 1 ° C between the two sides of the wood . Wood is a porous material with a small thermal conductivity value that can be used as a thermal insulation material. The thermal conductivity of wood is small compared to bricks, tiles, lime, cement, glass and the like in metals and building materials. Therefore, wood is one of the good thermal insulation materials. With the rapid development of China’s socialist construction, the application of wood as a heat insulation material will also be expanded. In steel mills, the temperature is high, with the insulation of wood and other building materials together, can constitute a good insulation of buildings. This has a beneficial effect on the health of workers; in civil buildings in the provinces of southern China, as well as precision
