紫外加速老化试验箱使用说明：
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。
Instructions for UV aging test box:
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, but the comparative test conditions provided by this device can quickly evaluate the anti-aging properties of materials, screen or improve new and old formula Monitoring product quality is relatively practical.
As ultraviolet light is the main lighting factor that causes the durability of outdoor products to decrease, coupled with the relatively stable spectral energy distribution of fluorescent tubes and low prices, the ultraviolet light aging test box has become a widely used in the world with its fast, convenient and economic advantages Weathering test models. As a simple model, this device is especially suitable for laboratories with limited economic conditions.
紫外加速老化试验箱结构与工作原理：
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，可以比较接近某些最终使用的环境条件，如温度剧变或雨水冲刷所造成的机械侵蚀等。
本装置的LUV型还可以在适当范围内通过温控机构调节光化反应的速率。
为满足耐候测试机坚固耐用的使用要求，本装置结构件普遍采用了耐蚀不锈钢材料。设计上力求结构简单、便于使用和维修。只需付出相对低廉的使用成本，就可使您在短时间内了解自然条件下长时间才能形成的材料损害，判定试验产品与对照样板之间的品质差距。
Structure and working principle of UV aging test chamber:
The rotating sample frame design can well compensate for the uneven light radiation defects caused by many factors such as aging of the lamp tube and the difference between batches, which saves the heavy workload of ordinary instruments that need to periodically switch the sample position in sequence.
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 closer to some end-use environmental conditions, such as sudden temperature changes or mechanical erosion caused by rain.
The LUV type of the device can also adjust the rate of the photochemical reaction through a temperature control mechanism within an appropriate range.
In order to meet the rugged use requirements of the weather tester, corrosion-resistant stainless steel is commonly used in the structure of this device. Designed to be simple in structure, easy to use and maintain. You only need to pay a relatively low cost of use, so that you can understａnd the material damage that can form under natural conditions for a long time in a short time, and judge the quality gap between the test product and the control sample.

LUV-II紫外加速老化试验箱注意事项:
★具有高辐照度水平的UVB光源，虽然能大度地加速试验进程，但有时也会对某些材料造成甚于天然曝晒的老化破坏，如过度变色。所以在评判与对照样板有差异的试样时，应注意这一因素。

★在没有戴护目镜时，不要用肉眼直接观察点亮的紫外灯。以免皮肤灼伤。
★如水位明显下降或LUV型试验箱的水位报闪亮，应及时补充去离子水，避免水泵在无水状态下运行。
★试验区域不洁和不使用去离子水都会在试样上生成妨碍观察的水渍，也影响设备元器件的使用寿命。

Note for LUV-II UV accelerated aging test box:
★ UVB light source with high irradiance level can greatly accelerate the test process, but sometimes it will cause aging damage to certain materials, such as excessive discoloration. Therefore, we should pay attention to this factor when judging the samples that are different from the control samples.
★ Do not use uncertified non-dedicated lamps.
★ Full-time duty personnel should be equipped to monitor the aging and safety status during the full test of the test.
★ The warehouse door must be opened or the lamp must be replaced with the power off.
★ When not wearing goggles, do not directly observe the lit UV lamp with the naked eye. To prevent skin burns.
★ If the water level drops significantly or the water level of the LUV type test box is shining, deionized water should be added in time to avoid the pump running in the anhydrous state.
★ The test area is not clean and does not use deionized water, it will generate water stains on the sample that hinder observation, and also affect the service life of equipment components.
★ During the entire test, the cooling fan on the electrical box should be ensured to operate normally.
★ To prevent inexperienced non-** personnel from randomly touching the random instrument.
★ Control samples should be installed in the axisymmetric position of the turntable respectively to obtain equivalent lighting conditions.
★ This device is a thin plate-intensive mechanism. Pay attention to safety and prevent abrasion during operation and maintenance.
