Ozone Resistance Test ChamberFeem ntau yog siv los ntsuas qhov ozone aging kuj ntawm cov khoom tsis yog xim hlau thiab cov khoom siv roj hmab. cov
Lub chamber no yog ib hom khoom siv tshwj xeeb uas siv los simulate thiab ua kom cov txheej txheem kev laus ntawm cov ntaub ntawv hauv ozone ib puag ncig. Nws muab qhov chaw kaw tsis pom kev, uas muaj huab cua nrog qhov tsis tu ncua ntawm ozone concentration thiab qhov kub thiab txias tsis tu ncua, yog li cov qauv (xws li roj hmab vulcanized, thermoplastic roj hmab, cable rwb thaiv tsev sheath thiab lwm yam khoom) raug rau ib puag ncig no nyob rau hauv static tensile deformation. Nyob rau hauv txoj kev no, ozone aging kuj ntawm cov ntaub ntawv xws li roj hmab tuaj yeem soj ntsuam. Los ntawm kev tswj tsis tau xws li ozone concentration, kub uniformity, thiab huab cua khiav ceev, kev laus ntawm cov ntaub ntawv nyob rau hauv txawv tej yam kev mob yuav simulated, thiaj li mus twv seb lub durability ntawm cov khoom nyob rau hauv tiag tiag siv. cov
Basic tswvyim ntawm ozone
Ozone, roj nrog lub teeb xiav xim thiab tsw ntxhiab tshwj xeeb ntawm qhov kub thiab txias, paub txog nws cov peev xwm oxidizing zoo heev thiab cov kab mob bactericidal.
Raws li lub zog oxidant, ozone feem ntau corrosive rau hlau. Tsuas yog kub thiab platinum, uas muaj kev cuam tshuam tsawg, yuav luag txhua cov hlau yuav raug kev txom nyem los ntawm corrosion nyob rau hauv ib puag ncig ozone. Hauv particular, txhuas, zinc thiab txhuas yuav oxidize sai heev thaum lawv nkag mus rau hauv ozone.
Txawm li cas los xij, hlau alloys nrog cov ntsiab lus siab chromium muaj qhov ua haujlwm siab rau corrosion los ntawm ozone.
Ozone kuj yog corrosive heev rau cov ntaub ntawv uas tsis yog xim hlau. Thaum tsim cov khoom siv ozone tsim, cov roj hmab zoo tib yam tsis haum rau siv los ua cov khoom sib khi vim nws yooj yim corroded. Xwb, silicone roj hmab los yog acid-resistant roj hmab uas muaj zog corrosion kuj yuav tsum tau xaiv.
Ozone aging test khoom
Ozone Resistance Test Chamber: cov cuab yeej siv los simulate ib puag ncig ib puag ncig.
Ozone generator: tsim ozone ntawm ib qho tshwj xeeb concentration.
Ozone ntsuas ntsuas: siv los saib xyuas thiab tswj ozone concentration.
Raws li cov kws tshaj lij kev lag luam ntawm cov cuab yeej kuaj ib puag ncig, BOTO GROUP muaj kev paub dhau los thiab kev ua haujlwm zoo heev hauv kev tsim cov cuab yeej kuaj kev laus. Lub hauv paus tsim tau nruab nrog cov cuab yeej tsim khoom siab heev thiab cov txheej txheem tswj xyuas nruj, thiab tuaj yeem muab cov neeg siv khoom nrog cov txheej txheem siab thiab cov khoom siv zoo ib puag ncig.
Test Principple
Hauv qhov kev sim no, cov qauv muab tso rau hauv ib puag ncig uas tswj qhov kub thiab txias thiab ozone concentration. Thaum lub sij hawm teem caij, cov qauv raug kuaj xyuas cov kab nrib pleb lossis tawg tawm. Kev ntsuam xyuas tuaj yeem ua tiav siv peb txoj hauv kev tshuaj xyuas hauv qab no:
Tom qab raug rau lub sij hawm thiab strain tej yam kev mob, cov qauv raug kuaj xyuas cov kab nrib pleb thiab qhov luaj li cas ntawm cov kab nrib pleb yog ntsuas yog tias tsim nyog.
Nyob rau hauv ib qho kev mob tshwj xeeb, lub sijhawm luv tshaj plaws rau cov qauv pib tawg yog txiav txim siab.
Rau ib lub sij hawm raug teev tseg, qhov siab tshaj plaws tseem ceeb heev uas tus qauv tsis tawg yog txiav txim siab.
Kev sim
Txawm hais tias ozone yog cov pa roj uas muaj cov ntsiab lus tsis tshua muaj nyob hauv huab cua, nws yog qhov tseem ceeb ua rau tawg ntawm cov khoom siv roj hmab. Kev kam rau siab ntawm cov khoom siv roj hmab sib txawv rau ozone txawv heev nyob ntawm ozone concentration thiab ambient kub. Los ntawm kev simulating thiab txhim kho ozone tej yam kev mob nyob rau hauv cov huab cua nyob rau hauv lub chav kuaj, cov qauv raug mus rau ib puag ncig uas muaj ib tug tas mus li ozone concentration thiab tsis tu ncua soj ntsuam cov kab nrib pleb.
