造成材料老化的主要因素是阳光和潮湿。耐候试验箱可以模拟由阳光、雨水和露水造成的危害。耐候试验箱利用氙灯模拟阳光照射的效果,利用冷凝湿气模拟雨水和露水,被测材料放置在定温度下的光照和潮气交替的循环程序中进行测试,用数天或数周的时间即可重现户外数月乃至数年出现的危害。人工加速老化试验数据可以帮助选择新材料,改造现有材料,以及评价配方的变化是如何影响产品的耐久性的。
风冷式氙灯耐气候试验箱采用长轴风扇电机,耐高低温之不锈钢多冀式叶轮,以达到强度对流垂直扩散循环。机械底部采用高品质可固定式PU活动轮。观察窗采用多层中空钢化玻璃。
产品功能Mtsy-27 xenon arc lamp weathering test chamber is a xenon lamp as the light source, simulating and strengthening weathering accelerated light aging test equipment, in order to quickly obtain near atmospheric aging test results, used to evaluate the weathering resistance of materials. Weathering test is an important means of screening formula and optimizing product composition in the process of scientific research and production, and it is also an important content of product quality inspection.
The main factors causing material aging are sunlight and humidity. The weathering test chamber can simulate the hazards caused by sunlight, rain and dew. In the weathering test chamber, xenon lamp is used to simulate the effect of sunlight, and condensed moisture is used to simulate rain and dew. The tested materials are placed in the cycle program of alternating light and moisture at a certain temperature for testing, and the outdoor hazards for months or even years can be reproduced in a few days or weeks. Artificial accelerated aging test data can help to select new materials, modify existing materials, and evaluate how formula changes affect product durability.
The air-cooled xenon lamp weatherproof test chamber adopts long axis fan motor, high and low temperature resistant stainless steel multi vane impeller, so as to achieve strong convection vertical diffusion cycle. The bottom of the machine adopts high-quality Pu movable wheel. The observation window is made of multi-layer hollow tempered glass.
