氙灯耐气候老化箱
Xenon lamp climate aging resistance box
Basic principle of xenon lamp climate resistance test chamber:
Weathering test is an important means of selecting formulas and optimizing product composition in the scientific research and production process. It is also an important content of product quality inspection. Product standards for materials such as coatings, plastics, aluminum plastic panels, and automotive safety glass require weathering test.
The main factors causing material aging are sunlight, temperature, and humidity. The weathering test chamber can simulate the hazards caused by sunlight, rainwater, and dew. The weathering test chamber uses xenon lamps to simulate the effect of sunlight exposure, and uses condensed moisture to simulate rainwater and dew. The tested material is placed in a cyclic program of alternating light and moisture at a certain temperature for testing. In a few days or weeks, the hazards that occur outdoors for months or even years can be reproduced. Artificial accelerated aging test data can help select new materials, modify existing materials, and evaluate how changes in formulas affect the durability of products.
