聚氨酯硬质泡沫塑料由于它的导热系数在常温下接近或低于空气,因此是常温下使用的隔热保温材料中隔热性能名列前茅的一种材料。近几年来由于能源紧张,这种材料在国外受到极大的重视和越来越广泛的应用。但是国内这种材料的应用则处于发展的阶段。这种材料导热系数的测试与研究在我国还是一个空白点,为此我们对聚氨酯硬质泡沫塑料的导热系数、 Polyurethane rigid foam because of its thermal conductivity at room temperature close to or below the air, it is used at room temperature insulation materials in the top insulation performance of a material. In recent years, due to energy shortage, this kind of material has received great attention and applied more and more widely in foreign countries. However, the domestic application of this material is in the development stage. The thermal conductivity of this material testing and research in our country is still a blank point, for which we thermal conductivity of polyurethane rigid foam,
