材料导热系数总表(比较齐全)

1、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、含水率、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保温材料（我国国家标准规定，凡平均温度不高于350 C时导热系数不大于0.12W/（m K）的材料称为保温材料），而把导热系数在0.05瓦/米摄氏度以下的材料称为高效保温材料。千卡/米时;ckcal/(m h - C )卡/厘米秒Cca
