Product introduction

The destruction of materials by sunlight and moisture in nature causes incalculable economic losses every year. The damage caused mainly includes fading, yellowing, discoloration, strength reduction, embrittlement, oxidation, brightness reduction, cracking, blurring and chalking. For products and materials exposed to direct or through glass windows, the risk of light damage is the greatest. Materials exposed to fluorescent lamps, halogen lamps or other light-emitting lamps for a long time will also be affected by photodegradation.

The equipment uses xenon arc lamp which can simulate the full sunlight spectrum to reproduce the destructive light waves existing in different environments. The equipment can provide corresponding environmental simulation and accelerated test for scientific research, product development and quality control.

It can be used in the selection of new materials, the improvement of existing materials or the evaluation of changes in durability after changes in material composition. The equipment can well simulate the changes of materials exposed to sunlight under different environmental conditions.

Simulated full sunlight spectrum

The light resistance of the material is determined by exposing the material to ultraviolet (UV), visible and infrared light. It uses the filtered xenon arc lamp to produce the full sunlight spectrum with the greatest consistency with the sunlight. The xenon arc lamp with reasonable filtering treatment is the best way to test the sensitivity of the product to ultraviolet and visible light in the long wavelength range in direct light or sunlight through the glass.

Light resistance test of indoor materials

Due to long-term exposure to fluorescent lamps, halogen lamps or other light-emitting lamps, products placed in retail outlets, warehouses or other environments will also undergo significant photodegradation. The test chamber can simulate and reproduce the destructive light generated in such commercial lighting environment, and can accelerate the test process with higher intensity.

Relative humidity control

Provide relative humidity control function, which is very important for many humidity sensitive materials, and many test protocols also require humidity control.

The equipment adopts a full spectrum xenon arc lamp to simulate the destructive light waves in the sunlight, including UV, visible light and infrared light. According to the desired effect, the light of xenon lamp is usually filtered to produce a suitable spectrum, such as direct sunlight spectrum, sunlight spectrum through glass window or UV spectrum. Each filter produces a different light energy distribution.

The service life of the lamp depends on the irradiance level used. The service life of the lamp is 1000 hours. The replacement of lamp tube is convenient and fast. The long-lasting filter ensures that the required spectrum is maintained.

When you expose the product to the direct sunlight outdoors, the maximum exposure time of the product in a day is a few hours. Even so, the most severe exposure occurs only in the hottest weeks of the summer. Xenon lamp weather resistance test equipment can speed up your test process, because through program control, the equipment can expose your product to a light environment equivalent to summer noon sunshine 24 hours a day. The average light intensity and light hours / days are much higher than outdoor exposure. Therefore, the test results can be obtained quickly.

Effects of rain erosion and moisture

Due to the frequent scouring from rainwater, the coating layer of wood, including paint and colorant, will have corresponding erosion. This rain washing action can wash away the coating layer with anti degradation effect on the material surface, thus directly exposing the material itself to the destructive effects of UV and moisture. The rain water spray function of the equipment can reproduce such environmental conditions to enhance the correlation of climate aging tests of some coatings. The spray cycle is completely controlled by the program and can be carried out under the light cycle or no light cycle. In addition to simulating the degradation of materials caused by moisture, it can also effectively simulate the process of temperature upheaval and rain erosion.

Moisture is also the main factor causing damage to some materials. The higher the moisture content, the faster the damage to materials. Humidity can affect the degradation of indoor and outdoor products, such as various textiles. This is because when the material tries to maintain a moisture balance with the surrounding environment, the physical stress borne by the material itself increases. Therefore, the greater the humidity range in the atmosphere, the greater the overall stress on the material. The negative effect of humidity on the weatherability and colorfastness of materials has been widely recognized. The humidity function of the equipment can simulate the influence of indoor and outdoor humidity on materials.

The heating system of the equipment adopts far-infrared nickel chromium alloy high-speed heating electric heater; High temperature, humidity and illumination are completely independent systems (without mutual interference); The output power of temperature control is calculated by microcomputer to achieve high precision and high efficiency.

The humidification system of the equipment adopts an external boiler steam humidifier, with automatic water level compensation, water shortage alarm system, far-infrared stainless steel high-speed heating electric heating tube, and P I . D ＋S . S . R. The system is under coordinated control with the channel.
