氙弧灯耐气候老化试验箱中黑板测量温度的条件

北京鸿达天矩氙弧灯耐气候老化试验箱黑板测量温度的条件氙灯老化试验箱试验样品的表面温度是不可能被准确断定的，这是因为被暴露材料的高表面温度主要依赖于辐射吸收、辐射发射、试验样品内部热传导、试验样品与空气或与试样架之间的热传递。由于检测单个试验样品的温度不够实际，所以我公司使用特定的黑板来作为测定和控制温度的感温件。

黑板温度计与黑标准温度计的本质区别在于黑板的绝热底座。浅色或热导性好的试样表面温度一般低于黑标准温度计所显示的温度，所以黑标准温度计显示导热性差的深色试样暴露面的温度。不同型号的黑板温度计和黑标准温度计适用于不同型号的氙灯老化试验机。

黑标准温度或黑板温度也会受周围空气温度和风速的影响。在低辐照度条件下，黑板温度计或黑标准温度计显示的温度与试样真实温度之间的差异很小。
中译英：Beijing hong da day moment xenon arc lamp weather aging test box in the blackboard measuring temperature condition of the surface temperature of the xenon lamp aging test chamber test sample is impossible to know exactly, this is because the exposed materials mainly depends on the highest surface temperature of the internal heat conduction radiation absorption and radiation emission, test samples, test samples with air or with heat transfer between the specimen holder. Due to the temperature is not the actual measurement of a single test samples, so I use a specific company to the blackboard as a measure and control the temperature of heat.

The board with black standard thermometer thermometer is the essential difference between the blackboard adiabatic base. Light and heat conductivity of good sample surface temperature generally under standard thermometer shows the temperature of the black, so black standard thermometer shows dark specimens exposed surface temperature of poor thermal conductivity. Different models of the blackboard and black standard thermometer thermometer is suitable for the different models of xenon lamp aging tester.

Black standard temperature or the blackboard temperature will be influenced by the surrounding air temperature and wind speed. Under the condition of low irradiance, the blackboard or black standard thermometer thermometer shows the temperature and real temperature difference between the sample is very small.
