涂料外饰面的太阳辐射吸收性能测试方法分析

ANALYSIS ON EXPERIMENTAL METHOD OF COATINGS' SOLAR ABSORBING PERFORMANCE

通过对室外综合温度的分析,介绍一种测试涂料外饰面太阳辐射吸收系数的间接方法,并通过对测试数据的分析与总结,验证该间接测试方法的可行性,结果表明,采用深色涂料外饰面的建筑吸收的太阳辐射热较浅颜色的多,而涂料外饰面层的粗糙度对建筑吸收太阳辐射热影响不明显。

Indirect method was introduced. The results show that this indirect method is feasible and some conclu- sions are put forward that buildings with coatings in dark color absorb more solar radiation than that in light color and the difference of solar radiation absorbed by the different roughness of coatings is not obvious. The references are provided for testing absorption coefficient of solar radiation of new coatings and the selection of external decora- tive materials in architectural design.
