Product Usage
The DRK647 xenon lamp weather resistance test chamber takes long arc xenon lamp as the light source, which simulates and strengthens the weather resistance and accelerated aging test equipment to quickly obtain near-atmospheric aging test results. The main factors that cause material aging are sunlight and humidity. The weather test chamber can simulate the hazards caused by sunlight, rain and dew. Using the xenon lamp to simulate the effect of sunlight, the tested material is placed in a cycle program of alternating light and moisture at a certain temperature for testing, and the hazards that occur outdoors for months or even years can be reproduced in a few days or weeks. Artificial accelerated aging test data can help select new materials, modify existing materials, and evaluate how changes in formula affect product durability.

The DRK647 xenon lamp weather resistance test chamber has become a common choice in the field of light and weather resistance testing, providing sufficient technical reference and practical proof for related industries. Weather resistance test is an important method for screening formula and optimizing product composition in scientific research and production process. It is also an important content of product quality inspection. It is used to evaluate weather resistance of plastic rubber, paint coatings, aluminum-plastic panels, automotive safety glass, textile printing and dyeing and other materials.
