Climatic Chamber UV Accelerate Weathering Aging Test Chamber Ultraviolet Testing Machine for Rubber Resistance

    Accelerated aging test mainly refers to the thermal oxygen aging test for rubber, plastic products, electrical insulation materials and other materials; or the ventilation aging test for electronic parts and plastic products. The aging test is divided into temperature aging, sunlight aging, loading aging and so on. These accelerated aging test methods mean reproducing, artificially and in a limited time, what would happen in months or even years. Generally, we use accelerated aging test chamber to do the test.

    UV aging test chamber can simulate environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation, and darkness in natural climate. By recreating these conditions, they are combined into one cycle, and it is automatically executed to complete multiple cycles.

    UV aging test chamber is suitable for accelerated weathering tests of paint, ink, chemical, rubber, paint, adhesive, etc.

      Standard definition:
    A fluorescent ultraviolet lamp that emits below 300nm and whose light energy is less than 2% of the total output light energy, usually called a UV-A lamp; a fluorescent ultraviolet lamp that emits below 300nm and whose light energy is greater than 10% of the total output light energy , Usually called UV-B lamp;
    The UV-A wavelength range is 315-400nm, and the UV-B wavelength range is 280-315nm;
17. Light source:
    The light source adopts 8 imported ultraviolet fluorescent lamps with a rated power of 40W as the light source. Ultraviolet fluorescent tubes are distributed in the middle of the machine.
    UVB-313 light source configuration; UV-B wavelength range is 280-315nm, the luminous spectrum energy of the tube is mainly concentrated at the wavelength of 313 nm;
    Since the energy output of the ultraviolet light will gradually decay over time, in order to reduce the impact of the test caused by the attenuation of light energy, the service life of every 1/4 of the eight lamps in this test box is: 1600H.

Humidification/Condensation System
1. The principle of temperature measurement: the dry and wet bulb principle (dry bulb temperature and wet bulb temperature) is used to detect the dry bulb and wet bulb measurements through the sensor, and the relevant data is transmitted to the meter. The meter calculates the humidity based on the difference between the dry bulb and the wet bulb temperature. , Automatically and directly displayed on the instrument.
2. Humidification: The water level control in the humidification system uses an electronic liquid level controller to control the water pump. It is equipped with a built-in fixed water tank, and the water depth is not more than 25mm.
3. Condensation: The test sample and its bracket constitute the inner wall of the box, and its back is exposed to the cooling air in the room. Due to the temperature difference between the inside of the test room and the room, the surface of the sample has a stable condensation condition. The test box has a reason The natural convection air flow generated by the lower part through the outer wall of the box and the passage of the test sample.
