UV Aging Test Chamber UV Aging Environmental Test Chamber
The test equipment simulates the damage caused by the sun's ultraviolet light, and the weather resistance test is carried out on the material by exposing the tested material to light under controlled high temperature. It uses ultraviolet lamps to simulate the radiation of sunlight, and simulates dew and rain through condensation and water spraying. In just a few days or weeks, the ultraviolet irradiation equipment can reproduce the effects of outdoors that take months or even years. Damage that takes time to occur, including fading, color change, tarnish, chalking, cracking, cracks, wrinkling, blistering, embrittlement, strength reduction, oxidation, etc. The test results can be used to select new materials and improve existing There is a change in the material, or the formulation of the evaluation material.
Irradiation system (simulated sunlight):
Light source: 8 imported ultraviolet fluorescent lamps with a rated power of 40W. There are UVA-340 and UVB-313 light sources for users to choose and configure. Like other lamps, the aging of the QUV lamp will cause the lamp output to drop. The QUV without the sun eye control system uses the method of rotating the position to compensate. This system can be used for many application standards, but it has inherent limitations. This method of rotating positions cannot compensate for the impact caused by different batches of lamp tubes or differences in the surrounding environment
UV cycle temperature control:
The components of the UV circulation system include a blower, air heater, air distribution system, black panel temperature sensor.
a) Blower: Installed at the air duct opening of the lower box of the equipment, the blower works continuously during the whole UV cycle.
b) Air heater: installed in the air duct above the blower, used to heat the air blown by the blower when needed.
c) Air distribution system: the air blown by the blower enters the test room through the air duct in the center of the water tray, and then is guided by the air guide to fill the whole test room
