材料导热系数总表(比较齐全)[表类文书]

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/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0.05瓦/米摄氏度以下的材料称为高效保温材料。千卡/米时 kcal/(mh )卡 / 厘米秒 cal/(cms )瓦 / 米 KW/(mK)
