Explanation: many polymer materials when used outdoors often get from the earth's surface and the atmosphere in space the destruction of the natural environment factors which affect its service life.In order to correctly evaluate the outdoor life, with a variety of environmental testing equipment simulating the outside world a variety of natural climate conditions, weather resistance of various products in the laboratory research has become a widely used and effective means.
For artificial accelerated aging, at present the world the most commonly used two kinds of light source is fluorescent uv lamp and xenon lamp.Fluorescent uv lamp spectral distribution can only simulate the sun's ultraviolet (uv) section of the part, so the model results with the actual situation of the outdoor use after exposure there is no consistency.And xenon lamp spectrum is to simulate the entire spectral distribution of sunlight, so using xenon lamp as light source to evaluate the real life of the polymer materials in the outdoor has higher feasibility.
Xenon lamp tubes filled with xenon gas, using xenon discharge and emit light.Radiate this light source of the spectral energy distribution is very close to the sun and natural light, and color temperature around 6000 k.And xenon lamp has certain stability, in the limited life span and its spectral energy distribution is almost not changed, this is because it part of the continuous spectrum of spectral distribution almost has nothing to do with the lamp input power change.Xenon lamp as a special light source, has the good consistency of electrical parameters, it is easy to ignite, and once lit, can instantly at the stable light energy output, and the electric parameters of the xenon lamp at work almost not influenced by external conditions.

Test principle
With the filter filtration of xenon arc lamp to the coating or polymer material for artificial climate ageing or exposure to radiation, its purpose is to make coating or polymer materials being certain after exposure to radiation, make the performance of the selected to produce a certain degree of change, or make a sample to achieve a certain degree of aging need be exposed to radiation.To monitor the performance of the selected should be material important performance in practical application.Exposure material performance can be made with the same material without exposure (contrast specimen) performance, or at the same time and exposure of performance known material (reference sample).
