Application Overview:
The UV accelerated aging chamber is mainly used in industries such as plastics, coatings, rubber, glass, aviation, optical and electrical products, and industrial fabrics to simulate artificial accelerated tests under conditions of sunlight, rain, and dew. It is used to evaluate changes in materials in terms of fading, loss of gloss, cracking, chalking, blistering, embrittlement, and oxidation. This provides a basis for improving material formulations and enhancing product performance. UV light accounts for only 5% of sunlight, but it is the main light factor causing the durability of outdoor products to decline. The most commonly used lamps in general UV test chambers are UVA-340, UVA-351, and UVB-313. Compared to other types of lamps (including xenon arc lamps), fluorescent UV lamps are more stable. The spectral power distribution (SPD) does not change with lamp aging, even after up to 5,000 hours of use. This results in more repeatable test results, reduces the need for lamp replacement, and lowers operating costs.
Types of UV Accelerated Aging uv chamber:
UVA-340 lamps are the best choice for simulating the UV part of sunlight. UVA-340 can accurately simulate the critical short-wave spectral range of sunlight, that is, the spectral range of 295-360nm. UVA-340 only generates the UV spectral range found in sunlight.
UVA-351 lamps can simulate the UV part of sunlight passing through window glass. They are suitable for indoor applications of materials and are used to reproduce the damage of some inks and polymers in the environment near windows.
UVB-313 lamps utilize short-wave UV light that is much more intense than that typically found on the Earth's surface. Therefore, for some materials, these lamps may produce inaccurate results. UVB-313 lamps are best used for quality control and research and development applications or for testing very durable materials.
