UV aging tester testing equipment
The structure of the test chamber is made of corrosion-resistant metal materials, including 8 fluorescent ultraviolet lamps, a water tray, a test sample holder, and temperature and time control systems and indicators.
2. The lamp power is 40W and the lamp length is 1200mm. The range of the uniform working area of the test box is 900 × 210mm.
3. The lights are installed in four rows, divided into two rows. The tubes of each row of lights are installed in parallel, and the center distance of the lights is 70mm.
4. The test sample is fixedly installed at a position 50mm away from the surface of the lamp surface. The test sample and its bracket form the inner wall of the box, and their backs are exposed to cooling air at room temperature due to the temperature difference between the test sample and the air inside the box. To create stable condensation conditions on the surface of the test sample during the condensation stage, the test chamber should generate natural air convection through the outer wall of the chamber and the channel of the test sample at the bottom.
5. Water vapor is generated by a water tray located at the bottom of the heating box, with a water depth not exceeding 25mm, and equipped with an automatic water supply controller. The water tray should be regularly cleaned to prevent the formation of scale.
6. The temperature of the test chamber is measured by a sensor fixed on a black aluminum plate (blackboard) with a width of 75mm, height of 100mm, and thickness of 2.5mm. The blackboard should be placed in the central area of the exposure test, and the measurement range of the thermometer is 30-80 ℃ with a tolerance of ± 1 ℃. The control of lighting and condensation stages should be carried out separately, and the condensation stage is controlled by the heating water temperature.
7. The test chamber should be placed in a test room with a temperature of 15-35 ℃, 300mm away from the wall, and should prevent the influence of other heat sources. The air in the test room should not circulate strongly to avoid affecting the lighting and condensation conditions.
