Xenon arc weathering vs UV weathering: differences in ray of light simulation

Abstract: 本文探讨了氙灯耐候老化试验与紫外光老化试验的差异。氙灯耐候老化试验使用氙弧灯模拟全太阳光谱,包括紫外光、可见光和红外光,适用于评估材料在不同环境下的耐光性和耐候性,常用于汽车、涂料、橡胶等材料。相比之下,紫外光老化试验采用荧光紫外灯,专注于模拟太阳光中的紫外线辐射,适用于检验材料在紫外线暴露下的耐候性。这两种方法各有侧重,选择时需根据材料性质和实际使用环境来决定。

UV aging test and XENON ARC weathering test are two common materials aging assessment methods. There are some obvious differences between them in terms of simulated environment, Light source and test purpose.

1. xenon arc weathering simulation environment

Xenon arc weathering mainly simulates the full sunlight Light spectrum, including ultraviolet, visible and infrared light. Using Xenon-arc lamps that can simulate the full sunlight Light spectrum, the xenon arc weathering Test Chamber can reproduce the light waves of Destructiveness that exist in different environments. This method can be used both to select New materials, to modify existing materials or to evaluate changes in durability after material composition changes.

XENON arc aging test is mainly used to test the weathering resistance and light resistance of automobiles, Coatings, Rubber, Plastics, pigments, gluing agents, fabrics, etc. During the test, the material samples are exposed to light and heat radiation of XENON-arc lamps for aging tests to evaluate the weathering and light resistance performance of some materials under the action of high temperature Light sources.

2. UV aging simulated environment

UV aging Test Chamber mainly simulates ultraviolet light in sunlight. Light source is used to simulate ultraviolet radiation and condensation in natural sunlight to conduct accelerated weathering resistance tests on materials. This test method is mainly used for weathering resistance tests of inorganic Non-metallic materials, organic materials such as Coating, paints, rubber, plastics and their products.

Ultraviolet aging test can observe the discoloration or fading of materials in a short time, and is suitable for inspection of the degree of aging of products and materials under changes in climate conditions such as sunlight, Humidity, temperature, condensation, etc.

3. Differences and applications

Although Xenon-arc radiation is the main test method for aging resistance in CHINA, Xenon-arc radiation and ultraviolet light aging test are widely used test methods abroad. These two methods are based on completely different principles to evaluate the weathering resistance of materials.

The XENON arc weathering test is designed to simulate the entire Light spectrum of the Sun, with the aim of simulating sunlight as comprehensively as possible. The UV weathering test focuses on simulating ultraviolet radiation in sunlight, focusing on the damage effect of ultraviolet light on materials.

When choosing an aging test method, researchers need to decide which method to use based on the specific material properties and the use environment. Xenon arc weathering is suitable for materials that need to fully simulate the solar Light spectrum, while UV aging tests focus more on examining the effect of ultraviolet rays on materials.
