Characteristics and basic principles of xenon lamp aging test chamber device
The structural characteristics of the xenon lamp aging test chamber:
1. The heating method is an inner tank water tank type heating, with fast heating and uniform temperature distribution.
2. The inner tank water level automatically replenishes water.
3. The drainage system uses vortex and U-shaped sedimentation devices for drainage, making it convenient for users to clean.
4. The sample holder is composed of a pad and an extension spring, both made of aluminum alloy material.
5. The bottom of the xenon lamp aging test chamber adopts high-quality fixed PU movable wheels.
Basic principle of xenon lamp aging test chamber:
The xenon lamp aging test chamber is an important means of screening formulas and optimizing product composition in scientific research and production processes. It is also an important application of product quality inspection. Materials such as coatings, plastics, aluminum-plastic panels, and automotive safety glass require weather resistance testing according to product standards.
The main factors causing material aging are sunlight and humidity. The weathering test chamber can simulate the hazards caused by sunlight, rainwater, and dew. The weathering test chamber uses xenon lamps to simulate the effect of sunlight exposure, and uses condensation moisture to simulate rainwater and dew. The tested material is placed in a cyclic program of alternating light and moisture at a certain temperature for testing. In a few days or weeks, the hazards that occur outdoors for months or even years can be reproduced. Artificial accelerated aging test data can help select new materials, modify existing materials, and evaluate how changes in formulas affect the durability of products.
The main characteristics of the xenon lamp aging test chamber are:
1. Ventilation and cooling device: The temperature ventilation and cooling system of the test chamber is automatically controlled by a temperature controller.
2. Wireless transmission technology is used to control the blackboard thermometer, effectively improving control accuracy.
3. Use fiber optic transmission to measure the radiation intensity of xenon lamps, avoiding measurement errors caused by temperature reasons.
4. Sample holder The sample holder rotates around the light source at a speed of 1r/min and is equipped with a blackboard thermometer BPT or a black standard thermometer BST. 5. Timing device: In order to record the working time of each test, the equipment is equipped with a timer on the operation panel to control the equipment time. The equipment will automatically shut down when the timing is completed.
6. Protection device: In order to ensure the normal operation of the xenon arc lamp and prevent damage, this equipment is a protective device that, in addition to the xenon arc lamp being ignited on the circuit and interlocked with the cooling water (i.e. the xenon arc lamp cannot be lit when the cooling water is not working), automatically extinguishes the xenon lamp and stops the entire machine from working if there is a cooling water malfunction during operation.
