材料导热系数总表

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（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。千卡/米.时.°C[kcal/(m-h-C)]卡/厘米•秒-C[cal/(cm-s-C)]瓦/米・K[W/(m・K)]焦耳/厘米■秒・°C[J/(cm.s.C)]英热单位/英尺■时・『[Btu/（ft・h・°F）]1X10-3X10-23601242X10-3110-21001X10-3X10-21材料名称导热系数W/mK分类描述A356159
