人造卫星温控涂层研制中必须建立真空紫外辐照模拟设备.我组实验室制造的设备用旋片式机械真空泵、油扩散泵和在真空室前再加液空冷阱造成系统10~(-6)乇真空,选用GGZ-300高压汞灯作光源,光源和试件都放在真空室中.该设备具有简便实用的优点.另外还可以用于其它一些宇航材料的模拟真空紫外辐照试验,如人造卫星上的太阳电池和结构材料等.测量温控涂层在真空紫外辐照前后的太阳吸收率和热辐射率,根据它们的变化确定材料受辐射的影响.文中列出经真空紫外辐照不同阶段的五种不同温控涂层性能变化数据.
In the development of artificial temperature-controlled coating, vacuum ultraviolet radiation simulation equipment must be set up, and the equipment manufactured by our laboratory, using rotary vane mechanical vacuum pump, oil diffusion pump and liquid air-cooled trap in front of the vacuum chamber, 6) Torr vacuum, choose GGZ-300 high-pressure mercury lamp as light source, light source and specimen are placed in the vacuum chamber. The device has the advantages of simple and practical. In addition can also be used for some other aerospace materials simulation of vacuum ultraviolet radiation test , Such as artificial satellite solar cells and structural materials, etc .. Measurement of temperature control coating in the vacuum ultraviolet radiation before and after the solar absorption and emissivity, according to their changes to determine the material by the radiation effects of the article listed by the vacuum ultraviolet Radiation different stages of five different temperature control coating performance data.
