UV Accelerated weathering test machine/equipment(GW-338)
This tester is used for test the material of fluorescent UV lamp light ,mainly on the material outside of change and test the new materials durability.
Accord with ASTMG53-77, GB, GJB, MIL, ASTM, CNS, IEC, JIS, AATCC, DIN, Fed Test, BS, SAE
The chamber is widely used in paint, resins, plastics, printing and packaging, aluminum, adhesives, auto, cosmetics, metals, electronics, electroplating, medicine, etc.
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.
1. Simulated sunlight
The damage of material durability is mainly caused by the suns 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 Earths 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.
