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.
