    8 Lamps Weather Accelerated UV Aging Test Chamber


    UV aging test box is the most widely used UV accelerated test equipment in the world, in coatings, ink, plastics, leather, electronics and other industries widely used. It takes only a few days or a few cycles to reproduce the damage that can take months or years outside: ageing including fading, discoloration, pulverization, blurring, degradation of embrittlement and oxidation.


    The damage of sunlight, rain and dew to the material is quickly and truly reproduced, and the single light resistance or single moisture resistance of the material is weakened or failed by the synergistic effect between ultraviolet light and moisture, so it is widely used to evaluate the climate resistance of the material.


    UV weatherproof test box meets test standards

    ASTM D4329-05 of Test Method for Exposure of Light Source in Plastic Laboratory

    ASTM of instrument operation methods for UV aging of nonmetallic materials

    Fluorescent UV Lamp for Artificial Climate Aging Test of Rubber and Plastic Materials

    ISO-4892-3:2006 of fluorescent UV lamps

    IV. The concept of ageing resistance
    In the process of processing, storage and use of polymer materials, due to the combination of internal and external factors, their properties gradually become bad, resulting in the final loss of use value, this phenomenon is called aging, aging is an irreversible change, is a common problem of polymer materials, but people can through the study of the aging process of polymer, take appropriate anti-aging measures, improve the aging resistance of materials, delay the rate of aging, in order to achieve the purpose of prolonging the service life.

    UVA340: can emit solar wavelengths from 315 nm to 400 nm. Its peak irradiation is at 340.

    UVA340 comparison tests for different tests are particularly useful for best simulating sunlight in the short-wave ultraviolet band

    V. UV light

    The first-order optical reaction is not sensitive to temperature change, however, the speed of the secondary reaction is closely related to temperature change. generally speaking, the reaction speed will be accelerated with the increase of temperature. therefore, during the UV exposure test, the temperature control is very important. it is more important to match the test temperature used in the accelerated test with the highest temperature encountered by the material in practical application. The temperature of the UV process in the equipment is set to any point in 50℃~70℃, depending on the illumination level and indoor ambient temperature. The temperature adjustment of the equipment is accomplished by a series of systems, such as air heater and water heater, which are directed by a controller with microcomputer calculus function.



    VI. Humidity

    As the temperature increases, the destructive power of moisture to the material will increase sharply. Therefore, temperature control is the most basic requirement in humid overgrowth. Further, the acceleration effect is required to maintain a high temperature environment during the wet process. so the temperature in the condensation process is set to 40℃~60℃ at any point.
