材料导热系数总表比较齐全

材料导热系数总表比较齐全公司标准化编码 [QQX96QT-XQQB89Q8-NQQJ6Q8-MQM9N]定义：导热系数是指在稳定传热条件下，1m厚的材料，两侧表面的温差为1度（K,°C）,在1小时内，通过1平方米面积传递的热量，单位为瓦/米·度（W/m·K,此处的K 可用°C代替）。

导热系数与材料的组成结构、密度、、温度等因素有关。

非晶体结构、密度较低的材料，导热系数较小。

材料的含水率、温度较低时，导热系数较小。

通常把导热系数较低的材料称为(我国国家标准规定，凡平均温度不高于350℃时导热系数不大于(m·K)的材料称为保温材料），而把导热系数在瓦/米摄氏度以下的材料称为高效保温材料。
