Foreword
The damage to materials caused by sunlight and moisture in nature causes inestimable economic losses every year. The damage caused mainly includes fading, yellowing, discoloration, strength reduction, embrittlement, oxidation, brightness reduction, cracking, blurring and powdering, etc. Products and materials exposed to sunlight, either directly or through glass windows, are at greatest risk for the effects of photodamage. Materials that are exposed to fluorescent, halogen or other luminous lights for extended periods of time are also affected by photodegradation.
The xenon lamp aging test chamber uses a xenon arc lamp that can simulate the full sunlight spectrum to reproduce the destructive light waves that exist in different environments. This equipment can provide corresponding environmental simulation and accelerated testing for scientific research, product development and quality control.
The xenon lamp aging test chamber can be used for tests such as selecting new materials to improve existing materials or evaluating changes in durability after changes in material composition. The equipment can well simulate the changes caused by exposure of materials to sunlight under different environmental conditions.
Simulate full sunlight spectrum
The xenon lamp aging test chamber measures the light resistance of materials by exposing them to ultraviolet visible light and infrared light. It uses a filtered xenon arc lamp to produce a full sunlight spectrum with maximum match to sunlight. A properly filtered xenon arc lamp is the best way to test a product's sensitivity to the longer wavelengths of UV and visible light in direct sunlight or sunlight through glass.
Lightfastness Testing of Indoor Materials
Products placed in retail locations, warehouses or other environments will also experience significant photodegradation due to long-term exposure to fluorescent, halogen or other luminous lamps. The xenon lamp climate test chamber can simulate and reproduce the destructive light produced in such commercial lighting environments and can accelerate the test process with higher intensity.
Simulated climate environment
In addition to conducting photodegradation tests, the xenon lamp aging test chamber can also become a climate aging test chamber by adding a water spray option to simulate the damaging effects of outdoor moisture on materials. Using the water spray function greatly expands the climatic and environmental conditions that the equipment can simulate.
Relative Humidity Control
The xenon lamp aging test chamber provides relative humidity control. This function is very important for many moisture-sensitive materials and many test protocols also require humidity control.
Control of light intensity
Light irradiance refers to the ratio of light energy irradiated on a flat surface. The equipment must be able to control the intensity of light irradiation to achieve the purpose of accelerating the test and reproducing the test results. Changes in light irradiance affect the rate at which material quality deteriorates, while changes in light wavelength (such as the energy distribution of the spectrum) affect both the rate and type of material degradation. The irradiation equipment is equipped with a light sensing probe, also known as the sun eye, a high-precision photometric system that can promptly display the decrease in light energy caused by the aging of the lamp or any other changes. Solar Eye allows the selection of appropriate light irradiance during testing and can even select a light irradiance equivalent to the midday sun in summer. The Solar Eye can continuously monitor the light irradiance in the irradiation chamber and accurately maintain the irradiance at the working set value by adjusting the power of the lamp. Due to long-term operation, when the irradiance drops below the set value, a new lamp needs to be replaced to ensure normal irradiance.
The influence of rain erosion and moisture
Due to the frequent erosion from rainwater, the coating layer of wood, including paints and stains, will suffer from corresponding corrosion phenomena. This rain-washing action washes away the anti-degradation paint layer on the surface of the material, directly exposing the material itself to the damaging effects of moisture. The rain spray function of this device can reproduce this environmental condition to enhance the correlation of certain coating weathering tests. The spray cycle is completely controlled by the program and can pass the clean water through the booster pump to be filtered and flushed with or without light cycle. In addition to simulating material degradation caused by moisture, it can also effectively simulate drastic temperature changes and rain erosion processes.
Moisture is also the main factor causing damage to some materials. The higher the moisture content, the faster the damage to materials will be. Humidity can affect the degradation of indoor and outdoor products such as various textiles. This is because the physical stress on the material itself increases as it attempts to maintain a moisture balance with its surrounding environment. Therefore, the overall stress on the material is greater when the humidity range in the atmosphere is larger. The negative impact of humidity on the weatherability and colorfastness of materials is widely recognized. The moisture function of this device can simulate the effect of indoor and outdoor moisture on materials.
Sudden Temperature Changes
Exterior coatings on roofs, automobile parts, and metal buildings or structures are subject to sudden temperature changes. For example, hot summer causes heat to accumulate inside the material, while sudden rain showers will quickly dissipate the heat. This severe temperature change impact is a challenge and test for many materials. The effect of such environmental conditions on the material can be reproduced through the device's water spray function. The infrared rays emitted from the lamps can reconstruct the heat accumulation process, while the cold water spray produces a dramatic temperature change. Temperature is not controlled during the rain spray cycle.
