UV aging test chamber/Accelerated weathering test chamber
The UV aging test chamber simulates the effect of sunlight with fluorescent ultraviolet(UV) lamps and carry out these circles automatically.While it simulates rain and dew with condensing humidity or waterspray.In a few days or weeks,the UV can reproduce the damage that occurs over months or years outdoors.The damages include fading,color change,chalking,cracking,crazing,embrittlement,strength loss.,etc.The test data can help you to select the new materials or improve the performance of materials.Chamber cover introduces the two-way flip type for easy opening and closing.Test specimen and the shelf constitute the trapezidal inner wall of the chamber.
Â
Experimental Methods:
Fix the samples on shelves and face the fluorescent lamp.There are not enough samples for selves,please fill it with black board to make sure the test chamber sealed.Testing temperature:can adopt 50,60 or 70ºC.Recommend 60ºC for test,temperature of condensation is 50°C,temperature fluctuation is ±3°C.The cycle of condensation includes two cycles:1, 4 hour UV lamp and 4 hour condensation; 2, 8 hour UV lamp and 4 hour condensation.
