研究分析辐照对镀膜玻璃校正发射率的影响程度

作为建筑节能的重要产品之一,镀膜玻璃组成的中空玻璃具有良好的阻隔热量传输的性能,高效的节能性符合建筑节能的发展潮流。而镀膜玻璃作为建筑外立面常用建筑材料,长期暴露于太阳光之下,需要具备良好的耐久性能。耐久性的高低决定了镀膜玻璃产品性能的稳定性。镀膜玻璃的校正发射率是影响中空玻璃传热系数的重要因素之一。本文主要利用耐辐照检测仪模拟镀膜玻璃在破坏性光波照射下,对不同时间段辐照后镀膜玻璃校正发射率的影响程度进行了研究。

Coated glass is one of the important products of building energy saving.The insulating glass composed of it has good perfor⁃mance of blocking heat transmission.High efficiency and energy saving conforms to the development trend of building energy saving.As a common building material for building facade,coated glass is exposed to sunlight for a long time,so it needs to have good durability.The du⁃rability determines the stability of coated glass products.The corrected emissivity of coated glass is one of the important factors affecting the heat transfer coefficient of insulating glass.In this paper,the irradiation resistance detector is used to simulate the coated glass under the ir⁃radiation of destructive light wave,and the influence degree of the corrected emissivity of the coated glass after irradiation in different time periods is studied.
