The xenon lamp aging tester uses a xenon arc lamp that can simulate the all-day spectrum to reproduce the destructive light waves
that exist in different environments.
The plant provides environmental simulation and accelerated testing
for research, product development and quality control.
The combined effect of sunlight, atmospheric gases, temperature, humidity and other factors, known as "atmospheric erosion", is to cause most organic materials to age and cause damage
.
Many organic matter works well in temperate regions, but they are completely unsuitable for use
in harsh tropical regions.
For example, the rapid deterioration and decomposition of coatings, the cracking and disintegration of cable skins, and the fading of pigments
.
The destruction of various materials caused by atmospheric erosion is generally not caused by a single factor, but by the comprehensive result
of the interaction of several different types of characteristic factors.
Although solar radiation is dominated by ultraviolet radiation, in practical applications, the influence of climate erosion factors is difficult to distinguish
.
For example, although the influence of only ultraviolet light on PVC is not obvious, the thermal failure effect is significantly enhanced
due to the main effect of oxygen.
Xenon lamp aging testing machines unexpectedly appear abnormal damage phenomena that are inconsistent with the natural atmospheric erosion effect, the reasons of which may be one or more of the following: (1) many laboratories use ultraviolet light sources that are very different from the natural spectrum; (2) In the acceleration test, after various factors such as ultraviolet radiation intensity, temperature and humidity are strengthened, the reaction speed of them under normal exposure conditions is not necessarily the same
.
(3) Xenon lamp aging tester usually can not simulate all natural climate erosion factors
