本文通过空心玻璃微珠涂料反射实验、隔热实验和SEM分析研究空心玻璃微珠用量对涂料反射和隔热性能影响,结果表明:空心玻璃微珠的适宜添加量为25%,反射率能达45%-65%,能降温9℃;涂料反射隔热性能主要是由空心玻璃微珠对太阳光具有反射和阻隔作用引起,其次还与空心玻璃微珠在涂层表面的排布有关。在空心玻璃微珠用量为25%时,空心玻璃微珠在涂层中形成由无数空腔形成的致密的阻隔层来反射太阳光和阻止热传导。 相似文献

纳米ATO(锑掺杂二氧化锡)是一种具有透明隔热功能的新材料。文中分别将纳米ATO掺混到聚碳酸酯(PC)树脂内和以水性聚氨酯为基料涂覆于PC板表面,制备透明隔热新型阳光板。比较了纳米材料在树脂中的分散和实际隔热效果,以及环境因素对隔热效果的影响。证实ATO均以纳米级颗粒均匀分散在树脂中,但因其固有的以吸收红外光为主、反射红外光为辅的隔热机理,ATO涂覆于PC阳光板表面比掺混进PC中更能起到透明隔热作用,微风能明显加强散热和隔热效果。本研究为低成本制备透明隔热新型阳光板提供了理论和实验依据。 相似文献

Coating technology on the summit – Mirror Layers for the Large Synoptic Survey Telescope in Chile This article focuses on mirror coating for the Large Synoptic Survey Telescope, which is being installed in Chile. The LSST coating system consists of a coating chamber for the deposition of highly reflective optical coatings and a cleaning and stripping station for the M1M3 and M2 mirrors. With the help of the sputtering process, bare and protected silver/aluminum coating recipes can be deposited. The cleaning and stripping station consists of a rotating washing/drying boom, perimeter platforms, and an effluent handling system within the M1M3 mirror cell. The article describes the status of the assembly work on the coating system. Furthermore, it provides information about the progress of factory testing, a about the basic design features and reflective/coating requirements and the coating results. 相似文献

介绍反光布的结构及反光原理,对其中形成反射层的真空镀铝技术做综述探讨。介绍了真空镀铝机的原理,主要包括真空系统和真空室。真空系统工作时,按照滑阀泵、罗茨泵、油增压泵、油扩散泵的顺序依次运行。真空室内卷绕室与镀膜室并联,其中卷绕室容积与镀膜室之比为3:1,工作时卷绕室的压力为镀膜室压力的10倍以上。其次,通过分析铝层结合力、温度湿度来阐述其对真空镀铝性能的影响。一般而言,玻璃微珠型的反光材料的镀铝层厚度控制在150~400A之间。为了保证该结合力,蒸发舟间隙为100~150mm,其与冷却辊的距离控制在160—240mm。当空气湿度大于85%时,考虑到被镀材料的放气,选择油性胶植珠的薄膜,否则真空度达不到要求。 相似文献

Optical coatings for deuterium fluoride chemical laser systems 总被引:1,自引:0,他引:1
The high-power laser system has brought an interesting challenge to the development of optical coatings. A wide variety of coating specifications that are often contradictory have to be fulfilled. The choices of deposition process as well as coating materials are critical to coating loss, damage threshold, long-term stability, and other optical properties. A number of optical coatings being newly applied to deuterium fluoride laser systems are presented. The 3.8-mum laser reflection coatings with high damage threshold, multichromatic beam splitters, antireflection coatings with widely separated dual-wavelength bands, and 0.55-14-mum wide-band reflective coatings have been developed on substrates such as Si, Mo, fused silica, chemical vapor deposition ZnSe. Superior results have been obtained with ion-assisted deposition and electron-beam evaporation. Approaches to coating design and practical aspects of coating development are also discussed. 相似文献

The normal spectral emittance of a thermal barrier coating system developed at the National Aeronautics and Space Administration Lewis Research Center was measured. This emittance was transformed into the hemispherical total emittance and was correlated to the ceramic coating thickness and temperature using multiple-regression curve-fitting techniques. Equations were obtained which can easily be used by a designer to calculate the coating system hemispherical total absorptance and emittance. The system is highly reflective and therefore can significantly reduce radiation heat loads on cooled gas turbine engine components. 相似文献

The aberrations of a multilayer-coated reflective Schwarzschild objective, which are influenced both by mirror surface profiles and by multilayer coatings, are evaluated with a phase-shifting point diffraction interferometer operating in the extreme ultraviolet. Using wave-front measurements at multiple wavelengths near 13.4 nm, we observed chromatic aberrations and wavelength-dependent transmission changes that were due to molybdenum-silicon multilayer coatings. The effects of chromatic vignetting due to limited multilayer reflection passbands on the imaging performance of the Schwarzschild optic are considered. The coating characteristics extracted from the interferometry data on the two-mirror optical system are compared with previously reported coating properties measured on individual mirror substrates. 相似文献
