The difference between an ultraviolet test chamber and a xenon lamp test chamber

Liuqin Technology to talk about the main difference between the ultraviolet aging test chamber and the xenon lamp aging test chamber, in fact, can be summarized from four aspects: First, the equipment structure of the turntable: the ultraviolet test chamber is not, the sample is fixed, and the xenon lamp test chamber adopts 360 ° rotation; Refrigeration: UV test chamber does not, xenon lamp test chamber has a refrigeration unit, can control temperature and humidity; Second, the simulated spectrum is not the same: xenon lamp: full spectrum, close to the natural sunlight test, the maximum coincidence simulates the full sunlight spectrum of nature; Ultraviolet: 313nm or 340nm wavelength band, visible and infrared band is very small, can most realistically simulate the spectrum
of the short-band part of sunlight.
Third, the aging test speed UV test chamber: fast Xenon lamp test chamber: slow selection must look at the aging mechanism of the material, if it is required to do the material formula test (that is, the product has not yet been finalized), to speed up the test process, and know that the product or material in the ultraviolet short band aging effect is greater, then choose the ultraviolet aging test chamber, otherwise, choose the xenon lamp weathering aging test chamber
.
Fourth, function: temperature: UV test chamber temperature range is not adjustable; Xenon lamp test chamber temperature adjustable; Humidity: UV test chamber humidity is not adjustable; Xenon lamp test chamber humidity adjustable;
