氙灯老化.doc

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：5S/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7040mm）；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312（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1501501mm；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7090%。（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。CycleFilter IrradianceWavelengthExposure cycleScope of applicationNotes1Daylight0.35W/m2/nm340nm102min light at 63 (BPT);18min light and water spray (air temp. not controlled)Commonly used exposure cycleIrregular condition 2Daylight 0.35W/m2/nm340nm102min light at 63 (BPT);18min light and water spray (air temp. not controlled);6h dark at 954%RH, at 24 (BPT).3Daylight 0.35W/m2/nm340nm1.5h light,70%RH, at 70 (BPT);0.5h light and water spray (air temp. not controlled);Exterior grade textile materials4Window glass0.30 W/m2/nm340nm100% light, 55%RH, at 55 (BPT);Indoor plastics5Window glass1.10W/m2/nm420nm102min light, 35%RH, at 63 (BPT);18min light and water spray (air temp. not controlled);Indoor textile materials6Window glass1.10W/m2/nm420nm3.8h light, 35%RH, at 63 (BPT);1h dark, 90%RH, at 43 (BPT);7Extended UV0.55W/m2/nm340nm1) 40min light, 505%RH, at 702 black panel temper- ature and 472 chamber air temperature;2) 20min light and water spray on specimen face;3) 60min light, 505%RH, at 702 black panel temper- ature and 472 chamber air temperature;4) 60mindark and water spray on specimen back, 955% RH, 382 (BPT) and 382 chamber air temperature.Automotive exterior materials7ADaylight 0.55W/m2/nm340nm1) 40min light, 505%RH, at 702 black panel temper- ature and 472 chamber air temperature;2) 20min light and water spray on specimen face;3) 60min light, 505%RH, at 702 black panel temper- ature and 472 chamber air temperature;4) 60min dark and water spray on specimen back, 955% RH, 382 (BPT) and 382 chamber air temperature.8Extended UV0.55W/m2/nm340nm3.8h light, 505%RH, at 893 black panel temper- ature and 622 chamber air temperature;1h dark, 955%RH, at 382 black panel temper- ature and 472 chamber air temperature.Automotive interior components9Daylight 180W/m2300400nm102min light at 63 (BPT);18min light and water spray (not controlled temp.).-10Window glass162W/m2300400nm100% light, 50%RH, at 89 (BPT).-11Window glass1.5W/m2/nm420nmContinuous light at 63 (BPT) 30%RH-12Daylight 0.35W/m2/nm340nm18h consisting of continuous light at 63 (BPT) 30%RH;6h dark at 90%RH, at 35 dry bulb temperature.-ASTM D2565-08本标准适用于室外用塑料及相关产品。CycleFilter IrradianceWavelengthExposure cycleScope of applicationNotes1Daylight0.350.02W/m2/nm340nm102min light at 632 (BPT);18min light and water spray (air temp. not controlled)Historical conventionIrregular condition 2Daylight0.350.02W/m2/nmor41.52.5 W/m2340nm300400nm18h, consisting of alternating intervals of 102min light at 632 (BPT) followed by 18min light with water spray6h dark, at 954%RH, at 382 chamber air temp. with on water spray(repeat)General plasitcs3Daylight0.350.02 W/m2/nm340nm1.5h light, 705%RH, at 773 (BPT);0.5h light and water spray.(repeat)Fabrics 4Daylight0.550.02 W/m2/nmor65.52.5 W/m2340nm300400nm40min light, 505%RH, at 702 (BPT);20min light and water spray;60min light, 505%RH, at 702 (BPT);60min dark, 955%RH, at 382 chamber air temp.
