Embodiment
Referring to accompanying drawing, enforcement of the present utility model is described in detail.
All Dielectric self-support (ADSS) anti-ultraviolet property test unit includes an airtight experimental cabin and a control section; Described control section is provided with illumination temperature instrument and light application time regulator, and condensation temperature regulator and condensation time regulator.
Described airtight experimental cabin is divided into two parts up and down, symmetry before and after experimental cabin 1 structure; The last cross section of experimental cabin is trapezoidal, and its inside has optical cable fixing device and ultraviolet lamp 4; The left and right sides wall on the top of experimental cabin is provided with optical cable patchhole 7, preferably is provided with 8 holes, can test 8 optical cables simultaneously; The two sides is provided with the optical cable clamp 3 that can open before and after the top of experimental cabin, is cover plate 2 outside the optical cable clamp 3.
Lower cross section at described airtight experimental cabin is rectangular, and its inside is provided with tank 5, and well heater 6 is set in the tank.
Illumination temperature instrument and light application time regulator in the middle of ultraviolet lamp 4 and the control section are electrically connected; 6 of well heaters are electrically connected with condensation temperature regulator and condensation time regulator in the middle of the control section.
In the middle of process of the test, photostage and condensation phase hocket, but the harm that simulated solar, rainwater and dew cause.Illumination temperature instrument and light application time regulator work in photostage.
The ultraviolet light simulated solar damaging effect that ADSS anti-ultraviolet property test unit uses ultraviolet lamp 4 to send, 5% the ultraviolet light though only have an appointment in the sunlight, but be to being exposed to the main cause that outdoor durable material causes the photochemistry infringement: this is because along with the reducing of wavelength, the Photochemical effects of light strengthen on the contrary.Thereby during to the harm of permanance product, need not reappear the long sunlight of all-wave in simulated solar, only need the simulation short UV light, because ultraviolet light is a diffused light source, so can need not intricately and rotate test agent to the specimen surface uniform irradiation.
After finishing photostage, condensation phase is started working, and condensation temperature and condensation time regulator are started working.ADSS anti-ultraviolet property test unit can be simulated the harm that is caused by sunlight, dew.This device is simulated rainwater and dew with the condensation moisture.Detected materials is positioned in light under the uniform temperature and the moisture alternate cycles by optical cable fixing device and tests.The harm type of simulation comprises: fade, variable color, loss of gloss, efflorescence, cracking, foaming, embrittlement, strength retrogression and oxidation.
ADSS anti-ultraviolet property test unit is simulated the effect of rainwater and dew at specimen surface with a kind of condensing mode of uniqueness.At the condensation duration of work, the tank 5 of experimental cabin bottom is heated by well heater 6 and produces steam, 100% relative humidity in the vapours maintenance cabin, and certain temperature rise arranged, because of sample is the sidewall that is stuck in experimental cabin, the cooling effect of surrounding air makes the temperature of specimen surface lower than steam temperature, and such temperature difference can make aqueous water continuously condense in specimen surface in whole condensation cycle process.
The gained condensate water is very stable, pure distilled water, and it does not contain the solid of dissolving, and this helps the reproduction of test findings; Got rid of water mark stain problem simultaneously.And also as neutral dew, the water that newly condenses is that dissolved oxygen is saturated, so must have the very strong agent of erosion.
Another advantage of the condensed system of this uniqueness is tested exactly and needn't be used distilled water or deionized water, so the chamber of ADSS anti-ultraviolet property can be used ordinary tap water, water is agglomerated on the sample behind the automatic distillation in evaporation process again.
Reach 12 hours owing to produce moist every day time when exposing out of doors, so the wetting cycle of ADSS anti-ultraviolet property chamber also will continue a few hours usually, the uv-exposure of ultraviolet case and condensation process should be carried out respectively, as placing under the natural climate condition.Be traditionally arranged to be illumination 8 hours, condensation 16 hours.
The ultraviolet cycle period,, photochemical reaction is usually to temperature and insensitive.But the speed of any reaction of Fa Shenging all depends on the height of temperature thereafter.The speed of these reactions is accelerated with the rising of temperature.So the temperature of control uv-exposure is very important.In addition, also should make the temperature of accelerated aging test consistent with the maximum temperature that material is directly exposed under the sunlight.Want to be arranged on arbitrary temperature between 40 ℃～90 ℃ in ultraviolet case medium ultraviolet exposure temperature according to illumination and environment temperature.
The order of severity that moisture capacity corrodes is aggravated along with the rising of temperature, is indispensable so control the temperature of moistening cyclic process.So it is necessary controlling by condensing temperature and condensation time regulator.And, accelerated test just must under higher temperature, carry out moist exposure test.The Controllable Temperature of condensation process is between 0～25 ℃ in the chamber of ADSS anti-ultraviolet property; The temperature of condensation process and ultraviolet light temperature are irrelevant fully.
