Introduction to the working principle of Xenon lamp aging test chamber

The Xenon lamp aging test chamber can simulate the hazards caused by sunlight, rain and dew, use the xenon lamp to simulate the effect of sunlight, and use condensed moisture to simulate rain and dew, and the material to be tested is placed at a certain temperature. The cycle program of alternating light and moisture Tests in the environment can reproduce the hazards that occur outdoors for months or even years in days or weeks, and artificial accelerated aging test data can help select new materials, modify existing materials, and evaluate how changes in formulations affect how product durability.

The Xenon Lamp Weathering Tester tests materials by exposing them to alternating cycles of light and moisture at a controlled high temperature. Using a xenon lamp tube to simulate the radiation effect of sunlight, and using condensation and water spray to simulate dew and rain, the Xenon lamp aging test chamber only needs a few days or a few weeks, and it can be reproduced in a few months or even years outdoors. Laboratory damage such as fading, color change, cracking, cracking, wrinkling, blistering, embrittlement, strength reduction, oxidation, etc., in the environment or the aging of various parts and components, which takes time to occur, is accurate The only testing equipment that can predict the service life of products with repeatability and reproducibility can provide corresponding environmental simulation and accelerated tests for scientific research, product development and quality control, and provide important test basis. The xenon lamp light source is considered to be the light source that best simulates the full solar spectrum, and the xenon lamp spectrum contains shorter ultraviolet wavelengths than the solar radiation is cut off, which can be filtered out by a filter. In addition, the xenon light source can also realize automatic control of light intensity, temperature, light period/dark period and humidity, simulating and strengthening polymer materials in natural climates subject to light, heat, air, temperature, humidity and rainfall as the main aging Destructive environmental factors, quickly simulate the effect of sunlight exposure in different climates, so as to obtain weather resistance similar to natural climates. At present, artificial accelerated aging test using xenon lamp has become a preferred and general photoaging test method.
