Outdoor product light degradation effect is mainly caused by ultraviolet light. According to different test conditions, the ultraviolet accelerated aging box has several different ultraviolet lamps to choose from. The fluorescent ultraviolet light of the QUV ultraviolet light accelerated aging box can simulate the most important short-wave ultraviolet light in the sun, and reproduce the aging of physical properties caused by illumination.Reliable aging test data can accurately correlate the weather (anti-aging) nature of the product, and helps the screening and optimization of materials and formulations. The world's most widely used ultraviolet accelerated aging box has been put into use in a global Range Rules.

UV accelerated aging box function introduction:
All QUV UV radial aging The model of the box provides hot coagulation moist cycles, a harsh and real damp exposure environment. In general, products exposed to outdoor are often in a humid state in humidity for 15 hours. QUV provides two wet simulation methods. Because some application conditions also require water spray to achieve the actual effect, some QUV models can run a condensation cycle and run water spray cycle.
* Condensation method
In the design of the ultraviolet accelerated aging box, the sample actually constitutes the side wall of the test chamber, and the back surface of the sample is exposed in the laboratory indoor air. The cooling effect of indoor air results in a low surface temperature than the water vapor temperature, thereby ensuring that the water vapor continuously condenses the surface of the sample. This condensate is a very stable pure distilled water. * Water spray
QUV spray type ultraviolet accelerated aging box can simulate the effect of rainwater, such as thermal impact and water erosion.Under certain practical applications, such as in the sun, the aggregated heat is rapidly dissipated due to a sudden shower, the temperature of the material will grow sharply, produce thermal shock, this thermal shock is for many The material is a test. The water spray of the ultraviolet accelerated aging box can simulate thermal impact and / or stress corrosion.
UV accelerated aging box:
QUV / Spray ultraviolet accelerated aging box
QUV / SPRAY UV accelerated aging box and standard The QUV / SE UV accelerated aging box is basically the same, and deionized water is recommended when spray cycle.
* Equipped with a water spray system, including nozzles, pipelines, control and drainage devices. * shortThe spray of time can simulate the thermal shock, and the long-term spray can be used to simulate mechanical erosion caused by rainwater. * Ultraviolet light, spray or condensation function can be realized.
UV accelerated aging box and xenon lamp accelerates the selection method of the aging box
The test principle of the two detection devices is completely different. Xenon lamp test chamber simulates all spectroscopy of sunlight, including ultraviolet (UV), visible light and infrared (IR). The xenon lamp spectrum is basically coincided with the solar spectrum within 295 nm to 800 nm.
QS-lab xenon lamp aging tank simulates all the spectrum of sunlight, which is used to test many products, which are more sensitive to long-wave bands, visible light and infrared rays of ultraviolet rays.Of course, regardless of how the test device is effective, if its purchase price is too high, then it does not actually apply value. That's why buy prices, operating costs, and maintenance costs are some important factors that cannot be ignored. These factors should also be considered when considering the advantages of a testing device.
