Product Details
Technical parameters of UV test chamber | Quotation | Pictures | Price |: Purpose
The UV test chamber is mainly used for artificial accelerated testing of plastic, paint, and rubber materials in simulated environments with sunlight, rain, and dew. Used to evaluate changes in materials such as fading, color change, gloss, cracking, blistering, brittleness, oxidation, etc. This provides a basis for improving material formulations and enhancing product performance.

The outer shell and inner liner of the device are made of high-quality stainless steel materials, and the sample rack 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, ensuring 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, only short wave UV light needs to be simulated.
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 great method. Most ultraviolet fluorescent tubes produce ultraviolet light, rather than visible and infrared light.
The best choice for simulating sunlight ultraviolet rays with UVA-340:
UVA-340 can simulate the critical short wave wavelength range of sunlight spectrum very well, that is, the spectrum with a wavelength range of 295 to 360nm. UVA-340 only produces spectra of UV wavelengths that can be found in sunlight.
UVB-313 is used for maximum acceleration testing:
UVB-313 can provide test results quickly. The short wavelength UV they use is stronger than the UV light waves typically found on the Earth's surface. Although these UV lights, which are much shorter than natural wavelengths, can greatly accelerate experiments
Exposure method: Steam condensation mechanism
After the specified irradiation time, the surface of the sample enters a simulated non irradiated state at night. At this time, the surface of the sample is still heated by a saturated mixture of hot air and water vapor in the exposure chamber, while the back of the sample continues to be cooled by the surrounding air, forming a condensation state on the surface of the sample.
UV irradiation sensor (optional)
The RTE UV lamp weather resistance test chamber is equipped with a UV irradiation sensor. It is a high-precision photometric control system that allows users to select the desired illuminance. Continuous monitoring of light intensity is possible. And fully automated * * maintenance. It can make timely corrections to the light energy caused by lamp aging or any other changes by adjusting the energy of the lamp tube.
The device is manufactured based on one or a combination of the following standards:
GB/T 16422.3-1997 Plastics Laboratory Light Source Exposure Test Method Part 3: Fluorescent UV Lamp
ASTM G53-88 Standard Operating Procedure for Light and Water Exposure Devices for Non Metallic Materials (Fluorescent UV Condensation Type)
GB/T 14522-93 Accelerated Test Method for Plastic, Coating, and Rubber Materials Used in Mechanical Industry Products under Artificial Climate
UV lamp weather resistance test chamber/safety protection measures:
1. Power overload and short circuit protection
2. Grounding protection
3. Overtemperature protection
4. Water shortage protection
5. Compression overvoltage and overload protection
6. To protect the equipment, all alarms will automatically cut off the power and sound a warning
