Overview

The xenon lamp test chamber for building materials is a device used to test the weather resistance and aging performance of materials under specific environmental conditions. Its core working principle is to accelerate the aging process of materials by simulating factors such as ultraviolet light, temperature, and humidity in the natural environment. As the core light source of the test chamber, xenon lamp can generate a spectrum close to sunlight, especially in the ultraviolet part, which can effectively simulate the irradiation of sunlight on the surface of materials.

Product Details

Xenon lamp aging test chamber for building materialsIt is a device that simulates natural climate (sunlight, temperature, humidity, etc.) to accelerate the testing of material weather resistance and aging performance. It is widely used in industries such as plastics, coatings, and textiles.

1、 Core working principle

Using xenon arc lamps to simulate solar spectra (including ultraviolet, visible, and infrared), combined with temperature, humidity, spray, and other control systems, to simulate the comprehensive effects of light aging, thermal aging, and humid heat aging in natural environments, quickly causing aging phenomena such as fading, cracking, and powdering of materials, thereby evaluating their weather resistance life.

2、 Key technical parameters

Xenon lamp configuration: commonly used single xenon lamp, double xenon lamp, power mostly 1.8kW, 3.0kW; The spectrum needs to be close to natural sunlight (such as complying with ISO 4892, ASTM G155, etc.), and some equipment comes with filters (such as quartz filters, borosilicate filters), which can simulate different scenarios (such as sunlight behind window glass).

Temperature control: The blackboard temperature (simulated material surface temperature) is usually 50-100 ℃, the box temperature is 30-80 ℃, and the temperature control accuracy is ± 1 ℃.

Humidity control: relative humidity of 30% -95%, meeting the requirements of wet heat aging testing.

Test cycle: The cycle period of light, spray, darkness and other stages can be set (such as 100 minutes of light+10 minutes of spray), which conforms to the natural day night/rainfall pattern.

Irradiance control: The irradiation intensity can be adjusted (such as 0.3-1.5W/m ² at a wavelength of 340nm) to ensure stable test conditions and reproducible data.

3、 Main categories 建筑材料氙灯试验箱

According to the volume of the test chamber: small (volume<100L), medium (100-500L), large (>500L), suitable for samples of different sizes.

According to the position of the xenon lamp: vertical xenon lamp (lamp placed vertically, sample surrounded), horizontal xenon lamp (lamp placed horizontally, sample on one side).

According to function: standard type (only for lighting, temperature and humidity), comprehensive type (with spray, condensation, blackboard temperature control).

4、 Application scenarios

Plastic industry: Testing the sun aging resistance of plastic parts (such as automotive exterior and home appliance casings).

Coatings industry: Evaluate the color retention and adhesion of paints and coatings.

Textile industry: Testing the light fastness of fabrics.

Electronics industry: Testing the weather resistance of outdoor electronic device casings and displays.

5Xenon lamp aging test chamber for building materialsKey points for use and maintenance

Regularly replace xenon lamps (with a lifespan of typically 1000-2000 hours) to avoid spectral drift.

Clean the filter and sample holder to prevent dust from affecting the uniformity of irradiation.

Calibrate temperature, humidity, and irradiance sensors to ensure accurate data.

Confirm that the samples are placed evenly before the experiment to avoid blocking light.
