摘要
导热系数是多孔材料的一个重要参数,影响多孔材料导热系数的因素很多,不同的材料有不同的导热系数。在多孔材料的组成固定之后,其导热系数主要随着温度、容重和含水率的变化而变化,其中对其影响最大的是含水率。
Thermal conductivity of porous materials is an important parameter, there are a number of fac- tors affecting the thermal conductivity of porous materials, and different materials have different thermal conductivity in the porous material. After the composition fixed, the thermal-conductivity mainly with the temper-ature, bulk density and moisture content changes, one of its greatest impacts is the moisture content.
