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. 1、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.
