MB611QUV UV aging test chamber
    The utility model is used for simulating the damage caused by ultraviolet light, rain water and dew, and by exposing the tested material to an alternating cycle of light and water at a controlled temperature, the materals can be tested.
    GB/T 14552-2008, GB/T 16422.3-1997, GB/T 16585-96, GB/T 16585-1996, GB/T 16422.3-1997, ASTM D4329, ISO 4892-3, ISO 11507, SAE J2020
    One. The case box of the test box:
    1, The box adopts all numerical control production, advanced technology, smooth lines, beautiful and generous.
    2, The inner box is made of SUS304 high grade stainless steel plate, and the outer box is SUS304 stainless steel plate or electrostatic spraying after special surface treatment.
    3, Box cover for two-way flip, open and close easy.
    4, The sample frame is made of stainless steel and aluminum alloy to make the net frame, which is convenient for the sample to be accessed.
    5, The tank is located in the lower part of the box, and the electric heater is built.
    6, The door opening device is used in the opening of the shell of the test box, which is convenient to open.
    7, In order to facilitate the movement, the foot wheel is installed at the bottom of the instrument, and the position of the test machine is fixed with the U ring after the position is fixed.
    Two. Test light source:
    1, The light source uses 8 imported ultraviolet fluorescent lamps with rated power of 40W. The ultraviolet fluorescent lamp tube is distributed on both sides of the machine, with 4 branches on each side.
    2, There are UVA-340 and UVB-313 sources for user selection.
    2-1, The luminescent spectral energy of the UVA-340 lamp is mainly concentrated at the wavelength of 340nm
           The luminescence spectra of 2-2 and UVB-313 lamps are mainly concentrated near the 313nm wavelength
    2-3, Usually we mark the UVA-340 lamp
    3, Because the fluorescent light energy output will gradually decay over time, in order to reduce the impact of energy due to light attenuation test, so the test box in eight tubes in every 1/4 fluorescent lamp life of all, an old lamp, replaced by a new lamp, ultraviolet light source lamp by the new beginning and the old lights, so as to obtain a constant output light energy.
    4, The effective service life of the lamp tube can be about 1600 hours.
    Three. Electrical control:
    1, The blackboard temperature and condensing temperature are controlled directly by the touch screen controller.
    2, The rest of the control components are basically imported electronic components.
    3, The irradiance uniformity: less than 4% (in sample surface).
    4, Blackboard temperature monitoring: using a standard Pt-100 blackboard temperature sensor to accurately control the sample surface temperature of the test process.
    5, Flume temperature monitoring: in the cycle test process, there is a test section is the process of dark condensation, it requires saturated water vapor which can generate higher temperature inside the box. When vapor meets relatively cold sample surface, it will coagulate dew on the surface of the sample.
    6, The test box is equipped with time controller with a range of 0 to 9999H, with accumulative time and power outage memory function.
    Four. Safety protection device:
    1, Temperature overtemperature protection in the box: when the temperature inside the box is over 90? 10%, the machine will automatically cut off the power supply of the lamp and heater, and enter the balance state to cool down.
    2, The trough with low water level alarm to prevent the heater from burning empty.
