UV accelerated aging testing machinePerformance characteristics:

The UV aging test chamber can simulate the hazards caused by sunlight, rainwater, and dew. UV uses fluorescent ultraviolet (UV) lamps to simulate the effect of sunlight exposure, and uses condensed moisture to simulate rainwater and exposed water. The tested material is placed in a cyclic program of alternating light and moisture at a certain temperature for testing.

The inner shell of the device is made of high-quality stainless steel material, and the sample holder is composed of an aluminum alloy frame type base frame liner plate and tension spring. The main controller of the device is an intelligent digital display controller, with a user-friendly operation method that is easy to learn and use, and different functional levels of instruments can be operated interchangeably. The input adopts a digital calibration system with built-in commonly used thermocouples for accurate and stable measurement. Equipped with positional adjustment and AI artificial intelligence adjustment functions, multiple alarm modes
Radiation source: UVA340 (0.68W/m2) ultraviolet fluorescent lamp or UVB313 (0.6W/m2) ultraviolet fluorescent lamp
Although ultraviolet light (UV) only accounts for 5% of sunlight, it is the main lighting factor causing a decrease in outdoor durability. This is because the photochemical reaction of sunlight increases as the wavelength decreases. Therefore, when simulating the destructive effects of sunlight on the physical properties of materials, it is not necessary to reproduce the entire spectrum of sunlight. In some cases, it is only necessary to simulate short wave UV light.
The reason for using UV lamps is that they are more stable than other lamps and can better reproduce test results. Using fluorescent ultraviolet lamps to simulate the effects of light on physical properties, such as decreased brightness, fading, peeling, etc., is a good method. Most ultraviolet fluorescent tubes produce ultraviolet light, rather than visible and infrared light.
