Quickly Assess UV Accelerated Aging Test Chamber , Convenience and Economy
Product introduction:
The device is suitable for accelerating aging test by light and water exposure, predicting the relative durability of non-metallic materials such as paint, paint, plastic, etc. It is especially suitable for observing the physical property damage of particularly durable materials, such as gloss reduction, haze, strength reduction, powder. Chemical, cracking, foaming, embrittlement and fading.
As with other laboratory accelerated tests, the actual test results of the device cannot be used instead of natural exposure to determine the actual endurance of the material. However, the comparative experimental conditions provided by the device can quickly assess the anti-aging properties of the material, screen or improve the old and new formulations. Monitoring product quality is relatively practical.
Because ultraviolet light is the main lighting factor that causes the durability of outdoor products to decline, coupled with the relatively stable spectral energy distribution and low price of fluorescent tubes, the UV aging test chamber has become the most widely used in the world with its advantages of speed, convenience and economy. The weathering test model. As a simple model, this unit is especially suitable for laboratories with limited economic conditions.
The rotating model frame design adopted by the device can well compensate for the unevenness of the optical radiation caused by many factors such as the aging of the lamp and the difference of the batch, and the heavy workload of the general instrument to periodically exchange the position of the template in order. .
Since moisture is an important destructive factor for accelerated aging, the device uses a water spray method to simulate the influence of moisture. By setting the spray time, it can be closer to certain end-use environmental conditions, such as sudden changes in temperature or mechanical erosion caused by rain wash.
This model can also adjust the rate of photochemical reaction through a temperature control mechanism within an appropriate range.
In order to meet the demanding requirements of the weathering tester, the structural components of the device are generally made of corrosion-resistant stainless steel. The design strives to be simple in structure, easy to use and maintain.
With a relatively low cost of use, you can understand the material damage that can be formed under natural conditions for a long time, and determine the quality gap between the test product and the control sample.
