1.Dab tsi yog cov kauj ruam rau kev ntsuam xyuas sab nraum zoov hnub ci?
Environmental Conditions: Ua tiav kev nyab xeeb sab nraum zoov.
Tej qhov chaw:
Arizona/Florida Exposure Zones (Tebchaws USA): Sawv cev kub, qhuav suab puam huab cua (muaj zog UV hluav taws xob, kub kub, kub sib txawv, tsis tshua muaj av noo) thiab kub, av noo maritime huab cua (muaj zog UV hluav taws xob, kub kub, high humidity, ntsev tsuag). Florida yog ib qho kev lees paub thoob ntiaj teb rau kev sim hnyav.
Lwm cov huab cua sawv cev: Xws li thaj chaw muaj kuab paug, siab - thaj chaw siab siab uas muaj zog UV hluav taws xob, thiab lwm yam.
2.Dab tsi yog cov kauj ruam rau kev kuaj xenon teeb?
Cov qauv: Feem ntau ua raws li ASTM G155, ISO 16474-2, thiab GB / T 1865.
Core Environmental Condition Cycles (siv cov voj voog sib xws ua piv txwv):
Illumination Phase:
Lub teeb Source: Lim xenon arc teeb.
Irradiance: Feem ntau tswj ntawm 0.35 lossis 0.65 W / m² @ 340nm (saib xyuas qhov tseem ceeb ntawm UV band).
Blackboard Kub: Feem ntau 63℃± 3℃lossis siab dua (simulating cov khoom kub ntawm qhov chaw).
Chamber Kub: Kwv yees li 40 degree.
Tus txheeb ze humidity: Feem ntau 50% ± 5% lossis qis dua (cov av qis feem ntau yog tswj thaum lub teeb pom kev zoo).
Duration: Eg, 102 minutes.
Txau / Tsaus Theem:
Txau: Simulates los nag, thermal shock, thiab condensation. Txau nrog dej deionized rau 18 feeb.
Kub / av noo: theem no yuav txo qhov kub thiab nce cov av noo kom simulate hmo ntuj los yog condensation tej yam kev mob.
3.Dab tsi yog cov kauj ruam rau kev kuaj kev laus ultraviolet fluorescence?
Feem ntau simulates kev puas tsuaj los ntawm ultraviolet lub teeb, condensation, thiab ya raws. Nws yog tshwj xeeb tshaj yog zoo rau UV- cov ntaub ntawv rhiab heev tab sis tsis pom thiab infrared spectra.
Cov Qauv: Feem ntau ua raws ASTM G154 thiab ISO 16474-3.
Core Environmental Condition Cycling (siv ib lub voj voog ua piv txwv):
UV irradiation theem:
Lub teeb Source: UVA-340 teeb (zoo simulates ultraviolet ntau ntawm tshav ntuj).
Kub: Feem ntau 60℃(blackboard kub).
Duration: Piv txwv li, 8 teev.
Condensation / ntub dej theem:
Lub hauv paus ntsiab lus: Rhaub dej tank tsim cov chav, uas condenses nyob rau sab nraum qab ntawm cov qauv los ua cov kua dej zaj duab xis.
Kub: Feem ntau 50 degree.
Tus txheeb ze humidity: 100% condensation.
Duration: Piv txwv li, 4 teev.
Cycling: Cov theem saum toj no UV thiab condensation yog tsis tu ncua cycled.
4.Dab tsi yog cov kauj ruam rau kev ntsuam xyuas corrosion?
Ntsej Tsuag Test:
Txuj: ASTM B117, ISO 9227, GB / T 10125.
Cov xwm txheej: 5% NaCl tov, qhov kub thiab txias 35 degree, nruam txau. Siv los ntsuas qhov kev tiv thaiv corrosion ntawm txheej txheej txheej thiab lawv cov kev tiv thaiv rau kev sib kis ntawm corrosion ntawm khawb.
Cyclic Corrosion Test (Ntau dua, muaj tseeb dua):
Cov Qauv: ASTM D5894, ISO 20340.
Cov xwm txheej: Lub voj voog dhau los ntawm ntau theem nrog rau cov tshuaj tsuag ntsev, ziab, av noo, thiab qhov kub thiab txias, muab qhov kev ntsuam xyuas ntau dua ntawm txheej txheej txheej dua li kev sim tshuaj ntsev ib zaug.
5.Dab tsi yog cov lus xaus thiab kev lag luam kev coj ua?
Kev Xaiv Xaiv: High- xim zoo-coated coils (tshwj xeeb tshaj yog rau kev tsim kho) feem ntau raug kev sib txuas ntawm xenon teeb aging thiab ntsev tsuag/cyclic corrosion testing los ntsuam xyuas lawv cov huab cua tsis kam thiab corrosion kuj.
Performance Claims: Suppliers often specify test results, such as: "Passed 2000 hours of xenon lamp aging (ASTM G155), gloss retention >80%, xim txawv ΔE < 2.0" lossis "Tau 3000 teev ntawm kev ntsuas ntsev ntsev, tsis muaj xeb liab."
Muaj feem xyuam rau Lub Neej Ua Haujlwm: Cov sijhawm ntsuas nrawm tsis tuaj yeem hloov pauv ncaj qha rau xyoo ntawm kev siv sab nraum zoov, tab sis lawv muab cov txiaj ntsig kev ua tau zoo. Feem ntau, cov khoom lag luam uas ua tau zoo hauv cov qauv ntsuas tau suav tias muaj lub neej ntev dua nyob rau hauv tiag tiag - ntiaj teb qhov chaw sab nraum zoov.
