Accelerated Aging Uv Test Chamber UV Weather Equipment

Uv Accelerated Weathering Aging Test Chamber can simulate the ultraviolet ray in the sun, rain and dew to damage the material, QUV using UV lamp simulate the effect ultraviolet ray of sunlight, cold rain and dew. Being tested materials are placed in a certain environment which the light and moisture are alternating.

1. Simulated Sunlight
The damage of material durability is mainly caused by the sun's ultraviolet ray, it produces very little visible or infrared spectral energy. We can choose according to different testing requirements of different wavelengths of UV ultraviolet light, because each lamp in the total energy and wavelength of UV radiation are not the same. Usually, UV lamp can be divided into two kinds of UVA and UVB.

2. UV Lamp Type
UVA-340 lamp: UVA-340 lamps can simulate short-wave UV light in the sunlight excellently, ie sunlight from 365nm to 295nm cutoff wavelength.
UVB-313 lamps: UVB-313 lamps are usually issued by short-wave UV radiation than the Earth's surface in the strong solar ultraviolet radiation, which can speed up the greatest degree of material aging.
UVA-351 lamp: Simulation of UV sunlight through windows, it is the aging of indoor materials for testing the most effective.


3. Temperature Control:
The temperature control in each cycle, the temperature can be controlled at a set value.At the same time the board can monitor the temperature of the thermometer.Higher temperature can accelerate the aging process, while temperature control for reproducibility of the test is also very important.

4. Water Spray System:
Sprinkler system with 12 nozzles, each side in the test room of 6; sprinkler system can run a few minutes and then shut down.This short cooling water samples quickly and create a thermal shock conditions.
