| Profile. | |||
| The UV Accelerated weathering test chamber simulates damage caused by solar ultraviolet light, and the material is subjected to weather resistance test by exposing the sample to light under controlled high temperature. It uses ultraviolet light tubes to simulate the effects of sunlight. In just a few days or weeks, the chamber can reproduce damage that can take months or even years outside, including fading, color changes, tarnishing, chalking, cracking, cracking, wrinkling, blistering, embrittlement, strength reduction, oxidation, etc., can be used to select new materials, improve existing materials, or evaluate changes in material formulations. 4 pieces together (UVA-340 and UVB-313 optional). | |||

| 2.Structure & Material | |||
| Structure: Benchtop type, open the door from the right to the left. Single cycling system for air flue in the box, there's one inlet axis weeding machine which improves the flow amount of air, the heating ability and the whole temperature uniformity in the test machine. Material: Inner box: high grade stainless steel plate Outer box: stainless steel plate SUS304 or stoving varnish for option. |
|||
| 3.Light source system | |||
| Types of light source (simulate the sunlight) Light source: 4 imported UV fluorescent lamps (ATLAS) with rated power of 40W, UVA-340 and UVB-313 light source for users to choose. Like other lamps, the aging of the QUV tube causes the lamp output to drop, and the QUV without the Irradiance meter control system uses the rotational position method to compensate. This system can be used for many application standards, but it has inherent limitations. This method of changing position does not compensate for the effects of different batches of lamps or the surrounding environment.  Fig. Lamp replacement method. A.UVA-340: A wavelength that emits sunlight from 365 nm to 295 nm, and its radiation peak is at 340 nm. UVA-340 is especially useful for control tests in different tests, with the best simulation of sunlight in the short-wave UV range. B.UVB-313: The wavelength range is between 280 nm and 315 nm. UVB-313 ages faster than UVA-340 lamps, but their shorter wavelengths than the sun cutoff point can have unrealistic results for many materials. |
|||
| 4.Temperature control | |||
| The components of the UV cycle system include a blower, air heater, air distribution system, and blackboard temperature sensor. a) Blower: Installed in the lower tank air duct of the equipment, the blower is continuously operated throughout the UV cycle. b) Air heater: Installed in the air duct above the blower to heat the air blown by the blower when needed. c) Air distribution system: The air blown by the blower enters the test chamber through the air duct, and then the air guide to the entire chamber. |
