采用稳态平板法研究了密度对岩矿棉绝热材料导热系数的影响，结果表明，对于化学组成确定的岩矿棉材料，在一个大气压下，存在着最小导热系数值相对应的最佳密度范围（８０～１００ｋｇ／ｍ３）；指出岩矿棉材料导热系数随着温度的升高而增大，主要是分布在其孔隙中的空气的作用，并给出了岩矿棉材料导热系数与温度之间的关联式 The effect of density on the thermal conductivity of rock wool thermal insulation materials was studied by steady-state plate method. The results show that for a rock wool mineral material with a chemical composition determined, there is an optimal density range corresponding to the minimum thermal conductivity value under a single atmospheric pressure. (80～100kg/m3); pointed out that the thermal conductivity of rock and mineral wool material increases with the increase of temperature, which is mainly the effect of air distributed in its pores, and gives the thermal conductivity and temperature of rock and mineral wool materials.
