摘要/Abstract

摘要： 进一步研究了粉体材料对太阳辐射吸收能力的定量表征方法.结果表明,当Vcolored/V(TiO₂)(有色粉体与TiO₂的体积比)<5%时,lg(1/R)(R是试样对太阳辐射的反射率)和Vcolored/V(TiO₂)呈直线关系.从直线的斜率和截距可得出粉体材料的吸光系数和最大穿透厚度.该方法具有普遍性,适用于各种有色粉体的测定.

关键词: 粉体材料, 紫外-可见-近红外反射光谱, 吸光系数

Abstract: UV-Vis-NIRreflectance spectra were used to characterize the absorptivities of colored powdery materials to solar radiation.It was found that the plots of lg(1/R)(Rmeans the reflectance of coating to solar radiation) against Vcolored/V(TiO₂)(volume ratio of the colored powdery materials to TiO₂) were straight lines in the range of Vcolored/V(TiO₂) less than 0.05.From the slopes and intercepts of the straight lines, the absorption coefficients and the maximum depth of penetration can be measured quantitatively.The method can be applied to characterization of the colored powdery materials.

Key words: Powdery materials, UV-Vis-NIR reflectance spectra, Absorption coefficients
