耐气候老化试验是一种综合气候试验装置，除进行耐气候老化试验外，还可进行高分材料的耐光性的测试，即高分子材料暴露于模拟透过玻璃的日光光谱的人造光源下来评价材料耐光性能。耐气候老化试验箱从光能、温度、降雨或凝露、湿度这几种主要气候因素进行模拟和强化的试验;采用能模拟全阳光光谱的氙弧灯来再现不同环境下存在的破坏性光波。Weather resistance test is a test device for comprehensive climate, in addition to the weathering test, also can make the high light fastness of materials testing, namely polymer materials exposed to simulated by fluorescent spectra of the glass artificial source down material light performance evaluation. Aging test box to simulate and intensified test from the main climate light, temperature, rainfall, humidity or condensation in these factors are climate resistant; with xenon arc lamp can simulate the whole spectrum of sunlight reproduction under different environments the destructive wave.

耐气候老化试验过程中湿度的重要作用,水在结冰时膨胀，所以材料中，特别是受潮后镀膜硬质板系统中的水份会产生膨胀和应力，从而导致涂膜的撕开、断裂或剥落。降雨会周期性地冲洗材料表面的尘埃和污秽，同时由于降雨频率的不同，也可能产生长期的老化作用。当雨水冲击曝露表面时，蒸发作用使试样表面迅速降温，这会导致材料的进一步物理降解。冰雨或冰雹在降落时携带强大动能，也会导致涂层或油漆的物理降解。

The important role of humidity weather resistance test process, the expansion of water in the ice, so the materials, especially after wet coating hard plate system in the water will expand and stress, resulting in the film tearing, fracture or flaking. Rain will wash the material surface dust and filth periodically, at the same time, because of the different rainfall frequency, may also have the effect of long-term aging. When the rain hit the exposed surface, evaporation and make specimen surface cooling fast, further physical degradation which causes the material. Freezing rain or hail in landing with strong kinetic energy, physical degradation will lead to coating or paint.

从各种角度来看，以和OH-形式存在的湿度在耐气候老化试验过程非常重要。在二氧化钛加色涂层和聚合物的粉化过程中就可以观察到湿度的化学作用。尽管无论有无氢或氢离子的化学参与，聚合物表面都会发生光化反应，但通过化学反应吸入的水份的循环作用会加强(甚至导致)表面材料的实际物理释放过程。湿度有时也会作为pH调节剂，特别是在考虑酸雨

作用时，酸雨对多种油漆和涂层有侵腐作用。

From a variety of perspectives, exist in the form of humidity and OH- is very important in the weathering test. In the process of titanium dioxide powder color coating and polymer can be observed chemical effect of humidity. Although the chemical with or without hydrogen or hydrogen ion is involved, the polymer surface occurs photochemical reaction, but the cycle is sucked through the chemical reaction of water will strengthen (even) the actual physical surface material release process. Humidity and sometimes as pH modulators, especially considering the role of acid rain, acid rain erosion corrosion effect on many kinds of oil paint and coatings.
