Nrog rau kev nthuav dav txuas ntxiv ntawm cov cuab yeej siv qib siab niaj hnub no, cov khoom siv hluav taws xob tau siv ntau dua thiab ntau dua hauv cov lag luam qib siab xws li airlines, aerospace, instrument panels, ntsuas qhov ntsuas, thiab tub rog. Tsis tas li ntawd, qhov ua tau zoo ntawm cov khoom siv hluav taws xob tau pom tseeb siab dua. Cov nqe lus.
Qhov ua tau zoo ntawm cov khoom siv hluav taws xob yuav ua rau cuam tshuam tam sim ntawd ntawm kev siv tshuab thiab khoom siv, thiab cov khoom siv hluav taws xob tsim ntawm lawv yuav tsum muaj lub peev xwm los tiv thaiv xeb los ntawm cov teeb meem ib puag ncig. Yog li, ntau cov kev cai xav tau zoo tshaj plaws kev ua tau zoo los tiv thaiv cov kua sab nraud (roj thiab / lossis kua) kev tshaj tawm rau hauv sab hauv los ntawm cov txheej txheem, lub suab lossis qhov, uas yuav ua rau muaj kev phom sij rau kev ua haujlwm ntawm cov khoom siv hluav taws xob.
Yog tias qhov kev ua haujlwm sealing tsis zoo, nws yuav tsis tuaj yeem tiv thaiv qhov kev yaig ntawm ib puag ncig, thiab photosynthesis yuav tshwm sim hauv qhov chaw ntuj muaj qhov kub thiab txias, hloov tau ib puag ncig ntawm cov av noo thiab cov khoom tsis zoo, uas yuav ua rau xaim hluav taws xob hauv cov hlau hlau lossis cov plated cov khoom siv hlau txheej txheej sab hauv ntawm cov khoom siv hluav taws xob. Cov txheej txheem tau xeb thiab rhuav tshem, ua rau lub ntsiab ntawm cov hluav taws xob hloov pauv, qhov kev ua tau zoo raug txo lossis qhov ua haujlwm ploj tam sim ntawd; Qhov tseeb ua haujlwm ntawm kev sib khi tsis zoo, thiab cov dej ua pa hauv sab hauv yog siab dhau. Thaum lub ntsuas kub yog ultra-qes txias, nws yuav ua rau lub tsheb xa mus ua rau cov tshuaj tsuag vuam ntawm qhov chaw sib tiv tauj, thiab tom qab ntawd ua rau nws ua haujlwm. Ploj mus; los yog txhawm rau ua kom zoo dua tiv thaiv kev siv hluav taws xob, tiv thaiv kev cuam tshuam ntawm lub teeb pom kev, thiab lwm yam, thaum cov khoom siv hluav taws xob raug kaw, kev ua tau zoo ntawm kev sib khi tsis zoo, uas yuav ua rau muaj kev cuam tshuam tam sim ntawd, thiab qhov kev cuam tshuam no yuav cuam tshuam loj rau daim ntawv thov ntawm cov khoom siv hluav taws xob. kev ruaj khov. Yog li, qhov pib txhua qhov hluav taws xob tiv thaiv cov khoom lag luam yuav tsum tau ua lub qhov ntsaws ruaj ruaj kom paub txog cov khoom siv hluav taws xob, kuaj qhov kev ua tau zoo ntawm cov khoom siv hluav taws xob, thiab xaiv cov khoom siv hluav taws xob nrog kev ua tau zoo sealing.
Kev xaiv ntawm cov khoom siv hluav taws xob tau txiav txim siab los ntawm kev sim tshuaj lom, thiab kev xaiv ntawm cov khoom siv sealing tsis zoo los yog siv tshuab tsis zoo ua rau cov teeb meem sib khi. Nws cov xau npog tau muab faib ua ob qho txheej txheem tag nrho: kev ua kom zoo thiab nrhiav kom tau ntxhib. Kev soj ntsuam zoo los ntawm kev siv lub nraub qaum rov ua qhov siab ntawm hydrogen pawg spectrometry paim quav. Nyob rau qib no, qhov kev soj ntsuam tshwm sim feem ntau yog cov tshuaj fluorine roj vapor npuas. Cov kev sim feem ntau nqa tawm cov kev tiv thaiv kom zoo ua ntej, thiab tom qab ntawv nqa tawm kev ntxig nrhiav kom tau.
Cov roj fluorine muaj cov hluav taws xob zoo tshaj plaws kev ua tau zoo, cov tshuaj lom neeg zoo nkauj organic plasticity, zoo-dielectric lub zog thiab zoo heev tsis kam mus rau qhov siab thiab qis kub kuaj ua haujlwm. Nws tiv thaiv corrosion ntawm cov khoom siv hluav taws xob thiab tsis ua mob rau ntau yam kev cuam tshuam tseem ceeb ntawm lub cuab yeej. Tus yuam sij rau cov kua txau zoo tshaj plaws rau qhov ua kom pom qhov txhawm txhawm rau suav nrog kev ua ob ntu ntawm nias hauv cov roj fluorine uas muaj roj tsawg thiab muaj roj fluorine ntau ntau thiab ua kom cov roj npuas tawg tuaj.
Thawj kauj ruam yog ua kom huv thiab huv cov khoom siv hluav taws xob hauv kev tshuaj ntsuam xyuas mus rau hauv cov hlab ntsha, uas tau muab ntim thiab nqus ntim, thiab tom qab ntawd ntxiv cov roj fluorine qis rau hauv lub nkoj nyob hauv qab qhov nqus ntawm lub tshuab nqus tsev twj tso kua mis kom tiav ntaus ntawv. Sau lub nkoj nrog N2 rau qee lub sijhawm. Yog tias cov cuab yeej soj ntsuam muaj phaj orifice txheem, cov roj fluorine roj tsawg kawg yuav nias rau sab hauv phab ntsa sab hauv ntawm lub cuab yeej ntsuas. Tom qab them tas, tshem tawm cov khoom siv hluav taws xob thiab muab tso rau hauv huab cua rau qee lub sijhawm kom tshem tawm cov roj fluorine roj tsawg rau ntawm qhov chaw ntawm cov khoom siv hluav taws xob tau kuaj.
Qhov thib ob kauj ruam yog txhawm rau nkag rau qhov cuab yeej qhuav dhau mus rau hauv cov roj kub uas muaj cov tshuaj fluorine uas tau muab rhaub kom kub txog li 125 °, thiab cov khoom siv sab saum toj yuav tsum tsis txhob nkag mus tsawg dua 5 cm rau hauv txheej tob. Raus tshuaj rau qee lub sijhawm, thiab soj ntsuam seb puas muaj npuas nyob hauv cov khoom siv hluav taws xob hauv qhov kev kuaj xyuas nrog lub zog loj-tsom iav. Yog tias cov npuas txuas mus ntxiv, nws qhia tau tias muaj teeb meem nrog kev ua tiav ntawm cov khoom siv hluav taws xob hauv kev tshuaj xyuas.
Cov ntsiab lus: Nrog txoj kev nthuav dav txuas ntxiv ntawm cov cuab yeej thev naus laus zis, nws daim ntawv thov yuav dhau los ua ntau dua, thiab cov kev cai zoo rau cov khoom siv hluav taws xob yuav ua rau ntau dua thiab nruj dua. Kev sim ua kom lub cev ntxau yog txoj hauv kev los ntsuas qhov zoo ntawm cov khoom siv hluav taws xob. Cov tseev kom muaj rau kev ntxig nrhiav ntawm cov khoom siv hluav taws xob tau txais ntau dua thiab ntau dua, thiab qhov yuav tsum ua tau loj zuj zus thiab loj dua.
