Xenon Weathering Test Chamber - Precisely Simulating Sunlight for More Efficient Weather Resistance Testing!
Why Conduct Xenon Lamp Weather Resistance Testing?
In the natural environment, materials can age and deteriorate due to factors such as light exposure, temperature and humidity changes, and rain. For example, they may fade in color, lose strength, and experience surface cracking and peeling.
Traditional outdoor exposure tests not only have a long cycle (usually 1 - 3 years), but are also easily affected by the climate.
The Xenon lamp test chamber simulates natural sunlight with a full - spectrum xenon lamp and combines temperature and humidity control to achieve rapid accelerated aging tests, providing results in just a few days or weeks!
Functions: Comprehensive Simulation of the Natural Environment for Accelerated Weathering
LIB Xenon Weathering Test Chamber uses a xenon arc lamp to simulate ultraviolet, visible, and infrared light in natural sunlight. Combined with functions such as temperature control, humidity control, and spraying, it reproduces the real - world aging process of materials under outdoor exposure conditions.
The main test functions include:
- Light fastness testing
- Weather - resistant aging testing
- Simulation of phenomena such as temperature - humidity cycling, cracking, discoloration, and powdering
- Analysis of changes in impact strength and flexibility
Structure of LIB Xenon Lamp Test Chamber with Excellent Performance
It is designed from multiple dimensions of the light source, chamber body, and configuration, with an ingenious architecture. The light source can highly simulate sunlight, the chamber body is durable and corrosion - resistant, and the configuration is precise and efficient, bringing excellent test performance and easily handling various material tests. Choosing it is definitely the right decision!
Light Source : The spectra of the xenon arc lamp❺ and sunlight are highly convergent. As an accurate gas - discharge lamp, it uses quartz globe sealing and filtration technology to precisely regulate its spectral energy distribution, perfectly simulating sunlight in different environments.
Materials: The inner liner of the working room❷ is made of SUS 304 stainless steel with a smooth surface, which is rust - proof and resistant to high and low temperatures and moisture erosion. The external material❶ is composed of a 4 - mm A3 steel panel with a 2 - mm protective coating, and after electrostatic treatment, it has excellent high and low - temperature resistance.
Sensors and Controllers: It adopts a PT - 100 Class A sensor❸ with an accuracy of 0.001 degrees. The real - time relative humidity is accurately displayed through the temperature difference conversion between a wet gauze and the real - time temperature. The PID programmable color touch - screen controller❹ is powerful. It can be connected to a computer, create multiple programs with multiple segments, support multiple languages, and the manufacturer can preset programs according to user requirements.
Xenon Arc Lamp: The water - cooled xenon lamp❺ has an inner quartz and outer borosilicate filter, with specifications of 4500W and 6500W, and an average lamp life of 1600 hours. It has good heat dissipation but consumes a lot of water. The black panel temperature (BPT) ❻ reflects the aging degree of the sample and is a standard monitoring index.
Sample Holders: The rotating sample holder❼ makes the irradiance received by the samples uniform and can hold 42 samples. The castors❾ with brakes and adjustable height facilitate movement; the water level meter monitors the water level in the tank.The spraying function, when combined with the independent waterway system, expands the simulated climate environment.
Model Differences: Meeting Diverse Testing Requirements
Models such as XL - 750, XL - 500, XL - S - 500, and XL - S - 750 differ in parameters such as internal dimensions, overall dimensions, sample holder sizes, irradiation sources, and irradiance ranges, facilitating selection according to actual needs.
the Key Parameters of LIB Xenon Weathering Test Chamber
- In terms of equipment parameters, the irradiance ranges from 100 - 1200W/m², with differences among different models. When testing ultraviolet - sensitive materials, the focus is on the 300 - 420nm wavelength band.
- The temperature ranges from ambient temperature to 100°C ± 2°C, and the BPT is maintained at 35 - 85°C ± 2°C. Precise temperature control simulates real - world aging.
- The humidity is maintained at 50 - 98% R.H ± 5% RH, and a stable "micro - climate" is crucial. The water - cooled xenon lamp, available in 4500W and 6500W, has an average life of 1600 hours and a spectrum similar to sunlight.
- The spraying cycle can be adjusted freely from 1 - 9999H59M to simulate a humid environment and adapt to various testing requirements.
It is essential to follow international standards such as ISO 105, ISO 4982 - 2, and ASTM G 155. In this way, the obtained test results are scientific and universal.
