The application fields of UV600

The UV Lamp Weathering Chamber (hereinafter referred to as BUV) uses a fluorescent ultraviolet lamp as a light source, and appropriately controls the temperature and humidity to periodically generate condensation on the sample to comprehensively obtain the damage of the sunlight, moisture and temperature on the polymer material. It can make a result of damage effects for polymer materials(material aging includes fading, loss of light, strength reduction, cracking, flaking, chalking and oxidation, etc.)

The ultraviolet light of the UV lamp can reproduce the effects of sunlight, and the condensation and water spray system can reproduce the effects of rain and dew.The radiation energy and temperature can be controlled throughout the test cycle.The typical test cycle is usually ultraviolet light irradiation at high temperatures and relative humidity in the 100% dark moisture condensation cycle.Typical applications is in paint coating, automotive industry, plastic products, wood products, glue, etc.

Simulated sunlight

Ultraviolet light in the sun is a major contributor to the durability of most materials. We use UV lamps to simulate the short-wave ultraviolet portion of sunlight, which produces very little visible or infrared spectral energy. We can choose UV lamps of different wavelengths according to different test requirements, because each lamp has different energy and wavelength in total UV irradiation. Generally, UV lamps can be classified into two types: UVA and UVB.

UVB-313 Lamp: UVB-313 The short-wavelength UV light emitted by the lamp is stronger than the sun's ultraviolet rays normally applied to the Earth's surface, which can accelerate the aging of the material to a greater extent. However, the lamp may cause unrealistic damage to certain materials. It is mainly used for quality control and research and development, or for running tests on materials with extremely high weather resistance.

UVA-340 lamp: The UVA-340 lamp is excellent for simulating short-wavelength UV light in sunlight, from 365 nm to the sun's cut-off point of 295 nm.

UVA-351 Lamp: Simulates sunlight through the window glass, which is most effective for aging the material in the test chamber.

(All the above lamps are imported lamps originally from the United States)

The biggest difference between the fluorescent UV accelerated aging test chamber and other domestic brands is that the energy during the whole test is controllable and automatically adjusted. It is well known that the energy of the test process is the most important factor causing the aging of polymer materials. In order to ensure the reproducibility and comparability of test results, ultraviolet light energy is a very important technical index. We use the principle similar to the sun's eye to automatically monitor the energy value of the test process. When the aging of the lamp does not reach the energy value set by the test, the system can automatically monitor and automatically replenish it immediately.
