UV Accelerated weathering test machine/equipment(GW-338)
Brief introduction:
This tester is used for test the material of fluorescent UV lamp
light ,mainly on the material outside of change and test the new
material's durability.
Corresponding standard
Accord with ASTMG53-77, GB, GJB, MIL, ASTM, CNS, IEC, JIS, AATCC,
DIN, Fed Test, BS, SAE
Applicable industries
The chamber is widely used in paint, resins, plastics, printing and
packaging, aluminum, adhesives, auto, cosmetics, metals,
electronics, electroplating, medicine, etc.
Main functions
UV weathering aging test chamber, the UV lamp can simulate the
effect of the sun, condensation and water spray system can simulate
the effect of rain and dew. The temperature can be controlled at
the process of testing. A typical test cycle is usually testing at
UV radiation of high temperature and the 100% humidity at dark;
Typically used in paint and coatings, automotive, plastic products,
wood products, glue, etc.
Main feature
1. Simulated sunlight
The damage of material durability is mainly caused by the sun's
ultraviolet ray. We use UV lamps to simulate sunlight in the
ultraviolet part of the short-wave, 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 lamps: Can simulate short-wave UV light in the sunlight
excellently, ie sunlight from 365 nm to 295 nm 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. However, the lamp may have caused some of the material does
not meet the actual damage. UVB-313 lamp is mainly used for quality
control and research and development, or on the weatherability of
materials strong run the test.
UVA-351 lamp: Simulation of UV sunlight through windows, it is the
aging of indoor materials for testing the most effective.
3. Moisture condensation environmentIn many outdoor environment,
the material wet day time can be up to 12 hours. The results show
that this result is the main factor of outdoor wet dew, not rain.
UV condensation through a unique function to simulate the outdoor
wet erosion. Condensation during the test cycle, the test chamber
at the bottom of the reservoir, water is heated to generate
superheated steam to fill the entire test chamber, hot steam to the
test chamber maintained at 100% relative humidity, and maintain a
relatively high temperature. Sample is fixed in the test room wall,
so the test sample surface exposed to ambient air in the test room.
4. 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
5. The water spray system for some applications, the water spray
can better simulate the end use of the environmental conditions.
Water spray in a simulated drastic changes in temperature and
rainfall caused by the thermal shock or mechanical erosion is very
effective.
