Supply aging resistance test box for plastic runway surface materials

  The anti-aging test chamber for plastic runway surface materials can reproduce the destructive light waves in different environments by using xenon arc lamps that can simulate the full sunlight spectrum, which can provide corresponding environmental simulation and accelerated aging tests for the production, development and quality control of plastic runway; It is applicable to the selection of plastic runway surface materials, the improvement of existing materials, or the change test of durability after the change of material composition
It can well simulate the changes of materials exposed to sunlight under different environmental conditions

  Xenon lamp climate resistance test chamber tests the material by exposing the tested material to the alternating circle of light and moisture under controlled high temperature
The xenon lamp tube is used to simulate the radiation of sunlight, and the condensed water and water spray are used to simulate dew and rain
The instrument only takes a few days or weeks to repair the laboratory damage such as the working condition in the environment or the aging of various parts and components that will take months or even years to occur outdoors, including fading, color change, cracking, cracking, wrinkling, blistering, embrittlement, strength reduction, oxidation, etc, It is the only testing equipment that can accurately and repeatedly predict the service life of products
It can provide corresponding environmental simulation and accelerated test for scientific research, product development and quality control, and provide important testing basis
Xenon lamp light source is considered to be the light source that can best simulate the full solar spectrum
The ultraviolet wavelength shorter than the cut-off of solar radiation contained in the xenon lamp spectrum can be filtered out through a filter
In addition, the xenon lamp light source can also realize the automatic control of light intensity, temperature, illumination period / dark period and humidity, simulate and strengthen the environmental factors of aging damage caused by light, heat, air, temperature, humidity and rainfall of polymer materials in the natural climate, and quickly simulate the sunlight exposure effect in different climates, so as to obtain the weather resistance similar to the natural climate
At present, the artificial accelerated aging test with xenon lamp has become a preferred and universal light aging test method
