复合薄膜表面红外辐射度检测及影响因素
Infrared radiance detection of composite film surfaces and influencing factors
摘要
Abstract
In order to measure the infrared radiance of low-infrared-emittance films and explore the influence of temperature,distance and viewing angle on the detection results,the theoretical relationship between the temperature ratio coefficient and infrared emittance was demonstrated.A testing system that could be compatible with multiple samples simultaneously was constructed.The temperature ratio coefficients of the composite films within the temperature range of 773-1 023 K were tested at four angles with 0°,15°,30°,45° and three distances with 0.8 m,1.2 m,1.6 m,respectively.The influence of detection temperature,distance and viewing angle on the temperature ratio coefficient of the samples was analyzed.The results show that within the tested temperature range,as the temperature increases,the temperature ratio coefficient of the samples gradually decreases;in terms of the tested distances,the temperature ratio coefficient of the samples at each position at 0.8 m is higher than that at 1.2 m and 1.6 m;in terms of the tested angles,the temperature ratio coefficients of the edge samples at 30° and 45° are significantly higher than those at 0° and 15°,and this gap increases with the increase of the testing temperature.The temperature ratio coefficients of the non-edge samples remain almost unchanged within the four tested angles.The research results of this paper lay a foundation for the subsequent research on the surface infrared emittance of multi-layer composite films.关键词
