    Simulating Ultraviolet raysUVand sunshine

    Although simulating ultraviolet rayis only 5% in the sunshine,it is the illumination factor which effects outdoors products durability declining.This is because sunshine photochemical reaction is increasing along with the wavelength reducing.When simulating the sunshine damaging the physical property of material,don't need to reappear the whole sunshine spectrum.In most situations,just need to simulate the short wave UV.

    Fluorescent lamp advantagequickly to get the result,simplified illuminance controlling,stable spectrum.

    UVA-340 It's the best choice to simulate sunshine simulating ultraviolet ray.

    UVA-340 Can simulate short wavelength range of the sunshine spectrum.The wavelength range is 295-360nm.

    UVA-340 Only can produce the UV wavelength which can be found in the sunshine.

     

    UVB-313Used in accelerated test to the full extent.

    UVB-313 can provide the test result quickly.Use the short wavelength which is more strong than the common UV wave.Alough these waves can accelerate the test more fastly to the full extent than the naterual UV wave,it will damage some materials.  

    Standard definition:Launching luminous energy which wave is 300nm or below is lower 2% of total output luminous energy ,this is one fluorescent lamp,we always call it UV-A light.Launching luminous energy which wave is 300nm or below is larger 10% of total output luminous energy,we always call it UV-B light.UV-A wavelength is 315-400nm,UV-B wavelength is 280-315nm.

     

    Simulating the effect of the rain and dew

       The time that outdoor material contacting humidity can be lengthened out to 12hours.The research results show that causing the outdoor humidity is dew not rain.Accelerated Weathering Tester uses a series of unique condensation theory to simulate outdoor humidity effects.In condensing circle of the chamber,there is a water storage tank in the bottom of the chambe and heating it to produce water steam.Hot steam make the chamber humidity is about 100%.This machine designs reasonable which can make sure the test sample can constitute of the chamber side wall,test back will expose in the indoor environment.

        Indoor air cooling will result in the surface temperature of the test sample lower several temperature. Difference in temperature will result in test sample surface generated liquid water in the condensation cycle. The condensation product is the stable pure distilled water..It can improve the test efficiency and avoid the water stain problem.

        Because the time that outdoor exposure touching humidity can lengthen out to 12 hours,the humidity period of Accelerated Weathering Tester will last several hours.We suggest every condensation period at least 12 hours.Please pay attention that UV exposure and condensation exposure proceeds respectively,it's consistent with the actual condition . 

     

    Adopt light source

       Use eight rated power rated 40W ultraviolet fluorescent lamp as the light source.The ultraviolet fluorescent lamp tube are distributed in the two-side of the chamber,each side has 4 lights.User can choose UVA-340 or UVB-313.

    UV-A wavelength range is 315-400nmtube luminescent spectrum energy focuses on 340nm.

    UV-B wavelength range is 280-315nmtube luminescent spectrum energy focuses on 313nm

    Because the ultraviolet fluorescent lamp output energy will reduce along with the time lengthening,in order to reduce the bad effect for the test because of energy attenuation,our test chamber every other ultraviolet fluorescent lamp 1/4 lifetimetube lifetime is1600H,we will change it a new tube,the replacing place is as below,the ultraviolet fluorescent lamps are constituted by new and old lights,and it will be a constant output light energy.
