The QUV aging test chamber does not simulate full spectral sunlight, but simulates the destruction of sunlight. The main radiation of the fluorescent tube is controlled in the ultraviolet band of the solar spectrum. This approach is effective because the short-wave UV is the most important factor in the aging of outdoor materials.UV testing can reproduce the destruction of sun, rain and dew. The equipment is carried out by exposing the material to be tested in the interaction cycle of controlled sunlight and moisture while increasing the temperature. The test equipment uses ultraviolet fluorescent lamp to simulate the sun, and can also simulate moisture effects by condensation or spraying. It is used to assess the changes in materials in color changes, gloss, cracks, bubbles, catalysis, and oxidation.
Each tube type used in UV test is different from the total energy and wavelength spectrum of ultraviolet light, and the fluorescent ultraviolet lamp is usually divided into UVA and UVB lamps, depending on their main output. geographic range.
UVA-351 simulation The ultraviolet portion of the sunlight of the window glass is mainly used for the photocondens of indoor products;
UVB-313EL: Widely used in the fast, saving test of durability materials, can accelerate the aging of materials, sometimes leading to Abnormal results. The consent of the customer must be obtained when using it.
