紫外光老化试验箱是**检测仪器,适用于通过光 水曝露加速老化试验,预测油漆 、涂料、塑料等非金属材料的相对耐久性,尤其适合观察特别耐用材料的物理性能破坏,如光泽降低、雾影、强度降低、粉化、开裂、起泡、脆化和褪色等。

Ultraviolet light aging test box is a testing instrument. It is suitable for accelerated aging test by light and water exposure. It predicts the relative durability of non-metallic materials such as paint, coatings and plastics. , Haze, reduced strength, chalking, cracking, blistering, embrittlement and fading.


紫外光老化试验箱采用的旋转样板架设计可以很好地补偿由于灯管老化和各批次差异等诸多因素带来的光辐射不均匀缺陷,省却了一般仪器需定期按顺序互换样板位置的繁重工作量。

由于水分是加速老化的重要破坏因素,本装置采用水喷淋方式模拟湿气的影响。通过对喷淋时间的设定,可以比较接近某些A终使用的环境条件,如温度剧变或雨水冲刷所造成的机械侵蚀等。

同其它实验室加速试验一样,不能利用本装置的试验结果替代天然曝晒来判定材料的实际耐久年限,但本装置提供的对比试验条件,对快速评估材料的抗老化性能、筛选或改进新老配方、监控产品质量是相对实用的。由于紫外光是造成户外产品耐用度下降的主要光照因素,加上荧光灯管相对稳定的光谱能量分布和低廉的价格,紫外光老化试验箱以快捷、便利和经济的优势成为世界上目前使用A为广泛的耐候测试机种。本装置作为简易机型,特别适合经济条件有限的实验室选用。

The design of the rotating sample frame used in the UV aging test chamber can well compensate for the defects of uneven light radiation caused by many factors such as lamp aging and differences between batches, eliminating the need for regular instruments to regularly switch the position of the template in order. Heavy workload.

Since moisture is an important destructive factor for accelerated aging, this device uses water spraying to simulate the effects of moisture. By setting the spray time, it can be relatively close to the environmental conditions of some end use, such as sudden temperature changes or mechanical erosion caused by rain.

As with other accelerated laboratory tests, the test results of this device cannot be used instead of natural exposure to determine the actual durability of the material. Monitoring product quality is relatively practical. Because UV light is the main illumination factor that causes the durability of outdoor products to decrease, coupled with the relatively stable spectral energy distribution of fluorescent tubes and low prices, UV light aging test boxes have become the world's current use of A wide range of weathering test models. As a simple model, this device is especially suitable for laboratories with limited economic conditions.
