材料导热系数总表

1、定义：导热系数是指在稳定传热条件下，1m厚的材料，两侧外表的温差为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/mK,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350C 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cal/(cm - s -
