Ultraviolet accelerated aging tester

Q 8/UV tube

Uva-340 lamp: The UVA-340 lamp is an excellent simulation of the Sun's short-wavelength ultraviolet light, that is, from 365 nanometers to 295 nanometers of sunlight cutoff.

UVB-313 tubes: UVB-313 tubes emit more short-wavelength ultraviolet light than the Sun's ultraviolet rays, which normally hit the Earth's surface, thus maximizing material aging. However, the lamp may cause impractical damage to some materials. UVB-313

Lamps are mainly used for quality control and research and development, or for the weather resistance of the material operation test.

UVA -351 Lamp: simulates the sun's ultraviolet light through the window glass, it is most effective for testing the aging of indoor materials.

In many outdoor environments, materials can be wet for up to 12 hours a day. Studies have shown that dew, not rain, is the main cause of this outdoor humidity. Q 8/U V simulates outdoor moisture erosion through its unique condensation function. During the condensation cycle of the test chamber, the water in the reservoir at the bottom of the test chamber is heated to produce hot steam, which fills the entire test chamber and maintains the relative humidity of the test chamber at 100% , and keep a relatively high temperature. The specimen is secured to the side wall of the test chamber so that the specimen's test surface is exposed to ambient air in the test chamber. The outward side of the specimen is exposed to the natural environment and has a cooling effect, which results in a temperature difference between the inner and outer surfaces of the specimen, there is always condensed liquid water on the test surface.

Because outdoor exposure to moisture can last up to ten hours a day, a typical condensation cycle typically lasts several hours. Q 8/U V provides two methods for moisture simulation. Many applications are condensation method, it is a good way to simulate outdoor wet erosion. All Q 8/U V models can be operated with a condensation cycle. Because some application conditions also require the use of water spray to achieve the actual effect, some Q8/UV models can run both the condensation cycle and the water spray cycle.

Temperature control

In each cycle, the temperature can be controlled at a set value. At the same time, the blackboard thermometer can monitor the temperature. Temperature increase can accelerate the aging process, and temperature control is also important for test reproducibility.

Water spray system

For some applications, water spraying can better simulate the environmental conditions of end-use. Water spray is very effective in simulating thermal shock or mechanical erosion due to temperature fluctuations and rain erosion. Under some practical conditions, such as sunlight, when the accumulated heat dissipates rapidly due to sudden rain showers, the temperature of the material will change dramatically, resulting in a thermal shock, this thermal shock is a test for many materials. Water spray at Q 8/U V can simulate thermal shock and/or stress corrosion.

The sprinkler system has 12 nozzles, 6 on each side of the test chamber; the sprinkler system runs for a few minutes and then shuts down. This short spray of water rapidly cools the sample, creating thermal shock conditions.

Radiation Intensity Control: optional, UV accelerated aging testing machine, UV accelerated weathering testing machine, UV weathering testing box, UV aging tester

The light intensity control system allows the user to set different light intensity according to different test requirements. The irradiation intensity is controlled by the feedback loop device; meanwhile, the service life of the fluorescent lamp can be extended.
