Kev ntxuav cov dej khov qhuav yog ib qho cuab yeej siv kho tsheb zoo uas tuaj yeem siv los ntxuav cov pa roj carbon ntau thiab cov av ntawm lub cav tsheb, lub tog raj kheej, lub tshuab nqus tsev thiab lwm qhov chaw, muab cov nyhuv tu kom huv si. cov
Qhov zoo ntawm kev ntxuav dej khov qhuav muaj xws li kev ntxuav tob tob, tsis muaj kev puas tsuaj, thiab kev ua haujlwm siab thiab ceev. Nws tuaj yeem tshem tawm cov pa roj carbon deposits thiab av ntawm lub tsheb qhov chaw. Piv nrog rau kev tu ib txwm siv, kev tu dej khov qhuav ua rau muaj kev puas tsuaj tsawg rau cov tsheb thiab yuav tsis khawb lossis ua puas rau saum npoo. Txawm li cas los xij, kev ntxuav dej khov qhuav kuj muaj qee qhov kev txwv thiab kev txiav txim siab, xws li tus nqi siab thiab tej zaum yuav tsis haum rau txhua lub tsheb lossis qhov chaw. Piv txwv li, qee cov khoom siv hluav taws xob lossis cov khoom rhiab yuav tsis haum rau kev ntxuav dej khov qhuav. Yog li ntawd, thaum txiav txim siab seb puas yuav ua cov dej khov qhuav qhuav, yuav tsum xav txog yam xws li hom tsheb, kev tsav tsheb thiab tus cwj pwm tsav tsheb ntawm tus kheej.
Tsis tas li ntawd, kev ntxuav dej khov qhuav kuj tau siv dav hauv kev tsim tsheb thiab aerospace. Hauv cov txheej txheem tsim tsheb, cov tshuab ntxuav dej khov qhuav siv cov khoom siv lub cev ntawm cov pa roj carbon dioxide (cov dej khov qhuav) uas sai sai sublimates rau hauv cov pa ntawm chav tsev kub thiab siab. Cov cua kub siab yog siv los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tshem tawm cov roj thiab cov impurities, nws tuaj yeem tshem tawm cov roj thiab impurities ntawm lub cav nto thiab ploj mus yam tsis muaj kab raws li cov dej khov qhuav sublimates. Tag nrho cov txheej txheem ntxuav tsis tas yuav tsum tau siv cov kuab tshuaj los yog dej, thiab tsis muaj kev puas tsuaj rau ib puag ncig thiab tsis muaj kuab paug. Hauv thaj chaw aerospace, cov tshuab ntxuav dej khov qhuav kuj qhia txog lawv qhov tshwj xeeb zoo, uas tuaj yeem tshem tawm cov khoom tso rau ntawm cov khoom tseem ceeb xws li cav thiab turbines kom ntseeg tau tias kev ua haujlwm thiab kev nyab xeeb ntawm lub dav hlau.
Nyob rau hauv luv luv, qhuav ice ntxuav yog ib tug npaum automotive tu tshuab, tab sis seb puas yuav ua kom qhuav ice ntxuav yuav tsum tau txiav txim raws li tus kheej xav tau kev pab thiab lub tsheb tej yam kev mob. Kev sab laj nrog ib tus kws tshaj lij kev tsav tsheb lossis chaw kho tsheb kom nkag siab lawv cov lus qhia thiab kev xav ntawm koj lub tsheb tuaj yeem pab koj txiav txim siab zaum kawg.
