材料导热系数总表(比较齐全)

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）。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 时 导 热 系 数 不 大 于0.12w/(mk) 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。0.05导热系数与材料的组成结构、密度、含水率、温度等因千卡/米时卡 /厘米秒瓦 /焦耳 /厘英热单位/英kcal/(m h) cal/(cm s )米kw/(m k)米秒j/(cm s )尺时btu/(ft h )12.78 10 -31.161.16 10
