汽车太阳膜的光谱特性分析

用带计算机控制系统的UV-Vis 8500型双光束紫外-可见分光光度计定量测量和分析了市场上某品牌汽车太阳膜的光谱特性。测量分析结果表明：普通膜系列太阳膜透视性能均良好, 隔紫外线效果一般，隔热效果也不理想;防爆膜系列太阳膜隔热效果、隔紫外线效果和透视性均一般;防爆抗磨系列太阳膜隔热效果和透视性均一般, 但隔紫外线效果与其他系列膜比较是最好的;超级前挡膜系列太阳膜透视性能均良好, 隔紫外线效果与隔热效果较好，是综合效果最好的汽车太阳膜。

Analysis of Spectral Properties of Car Solar Films

A dual-beam ultraviolet/visible spectrometer (UV-Vis 8500) automatically controlled by computer was used to measure qualitatively and to analyze the spectral properties of car solar films of a certain brand in the market. The experimental results indicate that transparency characteristics of the ordinary series of solar films are well, but their violet insulation and heat insulation properties are moderate, and moreover, their thermal-proof property is not ideal. The heat insulation, violet-proof and transparency properties of the anti-crack series are all in normal level. The heat insulation and transparency properties of anti-crack and anti-wear series are moderate, however, their violet insulation characteristics are better than those of other series mentioned above. For the super front film, its transparency property is excellent, moreover, its violet insulation and heat insulation properties are quite well. In general, it can be concluded that the super front series are the best car solar films.
