快速氙灯老化: 氙灯 配备了合适滤光器的氙弧灯维护得当时,其产生的辐射类似于地面日光的紫外和可见区的光谱能量分布。 1)石英套管的氙弧灯的光谱范围包括波长大于270nm的紫外光、可见光和红外辐射; 2)为了模拟直接的自然暴露,辐射光源必须过滤,以便提供与地球上的日光相似的光谱能量分布; 3)采用可减少波长320nm以下光谱辐照度的滤光器来模拟透过窗玻璃滤光后的日光; 4)当加热试样对光化学反应速率有不利影响,或在自然暴露下并不会引起热老化时,可以使用附加的滤光器来减少非光化作用的红外能量。 人工气候老化的相对光谱辐照度 透过窗玻璃的日光的相对光谱辐照度 Ci4000的滤镜组合 内滤镜 外滤镜 应用 Type S Boro(硼硅玻璃) Type S Boro(硼硅玻璃) 最常用的耐候老化试验 (Daylight) Type S Boro(硼硅玻璃) Soda Lime(钠钙玻璃) 最常用的室内耐晒老化试验(Window) Quartz(石英玻璃) Type S Boro(硼硅玻璃) 含有一些比太阳光更多更短波长的紫外光 Quartz(石英玻璃) Quartz(石英玻璃) 含有地球上不存在的短波紫外 CIRA(镀膜玻璃) Type S Boro(硼硅玻璃) 要求全波段辐射或温度稍低的耐候试验 CIRA(镀膜玻璃) Soda Lime(钠钙玻璃) 要求精确日光、全波段辐射或温度稍低的耐候试验 Q-Sun滤镜 Daylight 户外使用 Window 室内使用---纺织品、油墨等 Q/B 汽车产品,快速测试 水 PH:6.0-8.0;电导率:5μS/cm;固含量:<1ppm;硅含量: < 0.1ppm;水压:25-80psi 备注:1)冷凝(通过箱体内的热湿空气与样品背面的冷空气相遇,而使其冷凝在样品表面上);2)喷淋(直接采用符合要求的水,均匀喷淋至样品表面) 温度计 黑/白标温度 组成:一块厚约0.5mm的不锈钢平板(典型尺寸为70×40mm);平板对光面应涂敷有良好耐老化黑/白色涂层;铂电阻传感器应以很好的热传导连接在平板背光面的中心位置;平板的金属面安装在一块5mm厚的未填充聚偏氟乙烯(PVDF)底座上,且底座上应加工成有足够容纳电阻传感器的空间;传感器与PVDF板凹槽间的距离约1mm。 1)黑标比黑板的指示温度高3~12℃(隔热处理的缘故),但黑标的温度变化速率稍慢于黑板; 2)辐射量较少时,黑标/板温度与样品真实温度差别可能很小; 3)红外发射量很小的光源,黑板和黑标的温度或深浅色样品间温度差异很小; 4)黑/白板传感器的温度控制在设定温度±3℃内。 黑/白板温度 组成:由耐腐蚀金属平板组成,典型尺寸为150×150×1mm;平板对光面应涂敷具有良好防老化的黑/白色涂层;热敏元件(可以是一个涂黑杆状双金属盘式传感器或电阻传感器)应紧固在暴露表面中心位置;金属板背面应露置在老化箱的空气中 样品位置是否变换 是:如果样品暴露区域任何位置的辐照度均为最大辐照度的70~90%。(位置变换时间表应由所有相关方协商) 否:如果样品暴露区域任何位置的辐照度均至少为最大辐照度的90%。 测试标准 测试条件 ASTM D155-05a 本标准适用于非金属材料。 Cycle Filter Irradiance Wavelength Exposure cycle Scope of application Notes 1 Daylight 0.35W/m2/nm 340nm 102min light at 63℃ (BPT); 18min light and water spray (air temp. not controlled) Commonly used exposure cycle Irregular condition 2 Daylight 0.35W/m2/nm 340nm 102min light at 63℃ (BPT); 18min light and water spray (air temp. not controlled); 6h dark at 95±4%RH, at 24℃ (BPT). 3 Daylight 0.35W/m2/nm 340nm 1.5h light,70%RH, at 70℃ (BPT); 0.5h light and water spray (air temp. not controlled); Exterior grade textile materials 4 Window glass 0.30 W/m2/nm 340nm 100% light, 55%RH, at 55℃ (BPT); Indoor plastics 5 Window glass 1.10W/m2/nm 420nm 102min light, 35%RH, at 63℃ (BPT); 18min light and water spray (air temp. not controlled); Indoor textile materials 6 Window glass 1.10W/m2/nm 420nm 3.8h light, 35%RH, at 63℃ (BPT); 1h dark, 90%RH, at 43℃ (BPT); 7 Extended UV 0.55W/m2/nm 340nm 1) 40min light, 50±5%RH, at 70±2℃ black panel temper- ature and 47±2℃ chamber air temperature; 2) 20min light and water spray on specimen face; 3) 60min light, 50±5%RH, at 70±2℃ black panel temper- ature and 47±2℃ chamber air temperature; 4) 60mindark and water spray on specimen back, 95±5% RH, 38±2℃ (BPT) and 38±2℃ chamber air temperature.
