What is the Best UV Test Chamber for Solar Radiation Simulation
December 30, 2021
The uv test chamber produced by LIB can obtain real and reliable aging test data in just a few weeks or months. uv test chamber short-wavelength ultraviolet light and condensation cycle system can realistically simulate sunlight, dew, and rain on materials destructive effect.
The ultraviolet aging test chambr,QUV uses fluorescent ultraviolet lamps to simulate the aging of materials by sunlight.
Although ultraviolet (UV) energy only accounts for 5% of the total energy of sunlight, it is the main factor causing the degradation of outdoor product performance. Therefore, the degradation and aging of polymer materials can be tested only by ultraviolet light.
The variables that determine the relationship between test chamber exposure and outdoor exposure
|Geographic latitude of the exposure location (closer to the equator means more UV).
|Altitude (the higher the altitude means the more UV).
|Local geographical features, if there is wind, the test sample can be dried or close to water, which will cause condensation.
|The random change of climate from year to year can cause the aging change in the same place to reach 2:1.
|The direction of the sample (5° to the south to the vertical to the north)
|The working cycle of the test chamber (light time and humidity time).
|The working temperature of the test chamber (the higher the temperature, the faster the aging).
|Test the uniqueness of the sample.
