Description
Technical field of the present invention
The present invention relates to heliotechnics, relate in particular to the solar radiation test material that adopts optically focused and goods tolerance sunlight and weather conditions.
Prior art of the present invention
The combined action of atmosphere and solar radiation causes irreversible variation, degraded and unaccelerated aging in various material and goods.The most typical and most important (relevant with technical factor and economic factors) example of this variation shows as in the variation aspect the color of structured material, finishing material, paint and varnish and textile dye (be called as and fade and variable color) with as embrittlement and the effect of the breaking mechanical property decline that can access the polymeric material of proof one or two season after of the polyethylene film that uses in the greenhouse.
The speed of the demotion processes of these and other depends on atmosphere, temperature and is exposed to combined action under the light.At ultraviolet (UV) section (290-450nm) of solar spectrum, being exposed to is the most significant under the rayed.In the degradation process of material, the physical property of the main effect of the ultraviolet radiation of the sun is to cause by this fact of energy to fracture corresponding to the typical chemical bond of organic compound and organic element compound (organoelernentcompound) (C-C, CN, C-O, C-" F, C-Cl etc.) of the photon energy in the sunlight.
Light (visible light and infrared ray) irradiation material with the long wave section in the solar spectrum only is the reason that causes to the material heating.
To daylight on the fair irreducible change of～facet above-mentioned irreversible variation aspect coating and material painted be exposed to the key factor that dependence under the sunlight relates to the long-term action of the coating of buildings appearance under the indefinite compound lighting condition of city inner conversion and panel.Therefore, test and affirmation have very actual significance economically to the various materials and the goods of natural solar radiation sensitivity.
At present, the radiation in the multiple optically focused zone that the different atmospheric factor that simulation illuminate condition, especially simulation and are overlapped influences sample combines is a complicated technology problem.This is that technical factor by a series of reality causes: even specially for the spectrum of simulating best metal-Halogen lamp LED that natural solar irradiation develops also shows tangible linear structure, especially at interested ultraviolet spectral limit; Therefore, people should expect that the mechanism of the material degradation that natural sunlight and described light cause has significant difference; For the high confidence level of test result is provided, the homogeneity of radiant emittance on the whole target area equally should be very high (in the scope in a few percent); And in order to reduce owing to absorb sample under test condition that visible light in the sunlight and infrared ray partly cause by superheated factor, requisitely provide special-purpose measure (except sample can getablely cool off), specifically the visible light of solar radiation and infrared ray part are filtered the flux on inciding sample.
In prior art, disclosed a series of condensers, their representatives use the solar radiation of optically focused to be used for some parts of the solar energy equipment of quick daylight natural ageing test.For example, solar energy equipment discloses and a kind ofly to comprise that the condenser plan of being made up of 6 level crossings (each is of a size of 2 * 1.3 meters) is used for instrument that material is tested in No. 139513 IPC GO1H 17/02 of Soviet Union inventor certificate.These level crossings are mounted in pairs on 3 mechanically interconnected platforms.These platforms track on two circular paths that are laid on 7 meters radiuses one by one move together.The flat unit (being of a size of 2 * 1.3) of dress sample is positioned at this circular path center under test condition.Yet high material consumption and the big weight of bringing thus, complicated solar tracking kinematics and the high concentration ratio (being approximately 100) that can not obtain solar radiation are that this designs significant disadvantages.
In No. the 1746157th, Soviet Union inventor certificate, disclosed parabolic concentrator among the IPC F24J 2/42 as the some of described sun equipment.This condenser is made up of smooth facet.Yet the design of this condenser also is to be characteristic by complicated solar tracking and the high concentration ratio that can not obtain sun power.
In No. 1800243 IPC F24J 2/42 of Soviet Union inventor certificate, disclosed a kind of prototype condenser design of forming by smooth facet.It also only is could realize by use complicated rotary sample kinematics in objective plane that this condenser design has important shortcoming, the i.e. increase of optically focused ratio.
In sum, need not only to provide the improved device and the technology of the loss of the process that continues degradation during some months was by several years aspect the principal character that the performance of short-time test but also simulation cause taking place (color, machinery and other feature) and consequential trade quality really at material.
Added benefit of the present invention will partly be stated in the following description, partly will become obviously or can realize from the practice of the present invention by description.Advantage of the present invention can be achieved by the method for specially pointing out in claims.
