Product Information:
SI4000 Xenon Arc Weathering Test Chamber uses a xenon arc lamp as the light source to accurately simulate full-spectrum natural sunlight. By precisely controlling temperature, humidity, and periodic water spray on test specimens, the chamber comprehensively evaluates the combined effects of light, moisture, and heat on polymeric materials. It is designed to assess material aging phenomena such as fading, loss of gloss, strength reduction, cracking, peeling, chalking, and oxidation, providing reliable and repeatable data for durability and weathering performance evaluation.

FAQ
1. What types of aging effects can be evaluated using the SI4000 Xenon Arc Weathering Test Chamber?
The SI4000 is designed to evaluate a wide range of material aging effects caused by combined exposure to sunlight, moisture, and temperature. These effects include color fading, loss of gloss, reduction in mechanical strength, surface cracking, peeling, chalking, and oxidation. By simulating full-spectrum sunlight and periodic precipitation under controlled conditions, the chamber provides comprehensive insight into long-term environmental durability.
2. How does the SI4000 ensure uniform exposure for all specimens?
Uniform exposure is achieved through a three-layer rotating drum specimen rack combined with controlled airflow and precise irradiance feedback control. The rotating rack continuously changes the position of each specimen relative to the xenon light source, minimizing exposure differences. This design significantly improves test repeatability and reproducibility, especially when testing a large number of samples simultaneously.
3. Which irradiance wavelengths can be controlled during testing?
The SI4000 supports direct setting and closed-loop control of irradiance at 340 nm, 420 nm, and within the 300–400 nm range. This flexibility allows the chamber to meet different international standard requirements and simulate various solar radiation conditions. Optional second-wavelength monitoring further enhances compliance with global weathering test specifications.
4. What materials are suitable for testing in the SI4000?
The chamber is suitable for plastics, textiles, rubber, coatings, paints, varnishes, automotive interior materials, safety glass, and colored architectural materials. It is designed to evaluate both appearance changes and physical degradation under accelerated artificial weathering conditions.
