Plastic xenon arc lamp aging test

In order to more quickly determine the effects of radiation, heat, and humidity on the physical, chemical, and optical properties of plastics, artificially accelerated climate aging or artificially accelerated radiation exposure tests with specific laboratory light sources are often used. Plastics are exposed to more controlled conditions in laboratory equipment than in the natural environment, which serve to accelerate possible polymer degradation and product failure.
The plastic xenon arc lamp aging test uses a xenon arc lamp. In order to simulate the total solar radiation or the solar radiation through the window glass, it is composed of one or more filters. Its spectral range includes ultraviolet radiation, visible radiation and infrared radiation. Although the conditions of the xenon arc lamp source exposure test are controllable, it still cannot simulate the actual exposure conditions, and what is obtained from this is the relative durability of the plastic.
Zhongke Testing Reliability Experiment Center has the ability to test the reliability performance of various plastics, and provides professional testing services such as xenon arc lamp aging tests for plastics.

According to the different usage characteristics of various plastics, plastics are usually divided into three types: general plastics, engineering plastics and special plastics.
General plastics: polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and acrylonitrile-butadiene-styrene copolymer (ABS).
Engineering plastics: polyamide, polyformaldehyde, polycarbonate, modified polyphenylene ether, thermoplastic polyester, ultra-high molecular weight polyethylene, methylpentene polymer, vinyl alcohol copolymer, etc.
Special plastics: base-reinforced plastics (such as rag-reinforced or asbestos-reinforced plastics), inorganic mineral-filled plastics (such as quartz or mica-filled plastics), fiber-reinforced plastics (such as carbon fiber-reinforced plastics), etc.

1. Use a xenon arc lamp equipped with a suitable filter as a light source to simulate the spectral irradiance in the ultraviolet spectrum and visible spectrum regions in the total daily radiation spectrum.
2. In a controlled environment, the specimen is exposed to varying levels of light, heat, relative humidity, and water.
3. Optional variable exposure conditions:
a) Optical filter;
b) Irradiance;
c) Temperature when exposed to light;
d) When humidity needs to be controlled, the relative humidity in the test chamber during the xenon arc lamp illumination/dark cycle;
e) Wetting method of test sample;
f) Water temperature and moistening cycle;
g) The relative duration of the xenon arc lamp illumination and dark periods.
4. Wetting is achieved by spraying the test sample with softened water/deionized water, immersing the sample in water, or condensing water vapor on the surface of the exposed sample.
