The xenon lamp aging test chamber serves to replicate the environmental solar spectrum and various climatic conditions. It performs aging evaluations on materials that are subjected to sunlight exposure, mimicking effects like color fading, yellowing, discoloration, reduction in strength, brittleness, oxidation, decreased brightness, cracking, blurring, and powdering. This testing chamber can aid in the selection of novel materials, enhancement of current materials, or evaluation of durability shifts following modifications in material composition. As such, it represents an excellent all-in-one testing device for scientific exploration, product innovation, and quality assurance processes.
Xenon lamp aging test chamber Product Features:
1.1. This device can replicate the visual alterations of various materials, semi-finished goods, and finished products when exposed to atmospheric sunlight and ultraviolet rays. Typically, a light exposure test lasting 9 hours at 50°C is performed, which theoretically corresponds to six months of atmospheric exposure.
1.2. It satisfies the requirements for high-temperature aging tests, accelerating the degradation of vulcanized rubber. The system calculates the variation in tensile strength and elongation before and after heating. Generally, one day at 70°C is equivalent to six months of atmospheric exposure under theoretical conditions.
1.3. The device simulates sunlight for testing purposes, offering superior quality, extended service life, excellent cost-effectiveness, and broad applicability.
1.4. Ventilation and Cooling System: The temperature ventilation and cooling mechanism within the testing chamber is automatically managed by a temperature regulator. An internal refrigeration system cools the chamber as needed.
1.5. The equipment logs the operational duration of each test. A timer on the control panel allows users to set and monitor the testing time. Once the designated time elapses, the system automatically powers off.
1.6. Fiber optic transmission is utilized to measure the radiation intensity of the xenon lamp, thereby eliminating measurement inaccuracies caused by temperature fluctuations.
1.7. To safeguard the xenon arc lamp and prevent damage during operation, a protective mechanism is integrated. When the door is opened, the system automatically shuts off the xenon lamp and halts all operations.
1.8. The blackboard thermometer employs wired transmission technology, significantly enhancing the precision of control measurements.
1.9. A blackboard thermometer (BPT) or black standard thermometer (BST) is mounted on the sample rack to ensure accurate monitoring of testing conditions.
