Hom Kev Lag Luam Cov Khoom Uas Tsis Muaj Cov Khoom Siv Kom Qhuav:
1. Muaj qhov tshwm sim ntawm txau thaum cov khoom tau khiav tawm: Qhov no yog vim tias cov khoom lag luam tau nqus ua ntej nws khov. Lub tshuab ua ntej khov kub tsis tau poob qis dua hauv qab Eutectic taw tes kub, lossis tau poob qis dua lub eutectic taw tes kub, tab sis lub sijhawm tsis txaus, cov khoom khov tseem tsis tau ua tiav. Kev daws teeb meem yog txo cov ua ntej khov txias thiab txuas lub sijhawm ua ntej khov.
2. Cov khoom muaj shrinkage thiab bubbling: Qhov no yog ib nrab melting thaum lub sijhawm ua kua, thiab cov khoom siv qhuav, ua rau cov khoom siv kom ntau dua vim yog cov cua sov Eutectic lossis cov khoom siv kub heev lossis cov neeg pluag Lub tshuab nqus tsev. Kev daws teeb meem yog txo qis qhov kub cua sov thiab nce lub tshuab nqus tsev ua kom qhuav ntawm lub thawv kom qhuav. Cov khoom kub yuav tsum tau tswj kom nws 5 degree qis dua Eutectic taw tes lossis cais tawm kis kub.
3. Tsis muaj tus qauv ruaj khov: Qhov no yog vim tias cov khoom siv qhuav me me, thiab tsis muaj pob txha yog nqa mus rau sab nraud ntawm lub khob los ntawm sublimation vapor ntws. Kev daws teeb meem yog ua kom cov khoom lag luam lossis ntxiv kom muaj kev zam.
4. Cov khoom tsis tau qhuav: khov-qhuav yog ua tiav thaum muaj cov kua dej khov rau hauv cov khoom, thiab cov khoom khov me me los ntawm cov khoom qhuav, tsim cov "tsis muaj peev xwm". Thaum cov kua muaj ntau, cov khoom qhuav yog tag nrho cov yaj rau hauv cov kua thiab ua cov kua muaj zog. Thaum cov khoom no tawm ntawm lub thawv, yog tias koj kov hauv qab ntawm lub khob, nws yuav hnov txias. Txawm hais tias cov khoom lag luam zoo li zoo, cov ntsiab lus dej uas nyob ntawm cov dej tsis muaj txiaj ntsig. Qhov kev daws teeb meem yog kom nce cov cua sov, nce qhov kub ntawm cov phaj tov lossis siv lub sijhawm nqus dej, thiab lub sijhawm subting qhuav yuav tsum tau txuas ntxiv.
5. Cov khoom lag luam uas tsis pom xim: cov khoom muaj cov qauv crystalline, uas yog tshwm sim los ntawm lub qeeb qeeb. Kev daws teeb meem yog kom nce qhov ua kom khov khov thiab tsis nyob ntawm qhov kub thiab txias nyob ib ncig ntawm {1} qib kom khov cov khoom muaju me me. Qee zaum lub voj voog ntawm cov kab xoother tuaj yeem pom hauv cov khoom, uas feem ntau tshwm sim los ntawm lub sijhawm luv luv thaum sublimation, thiab luv luv hluav taws xob yuav ua rau qhov no.
6. Cov txheej txheej sab saud ntawm cov khoom lag luam yog qhov zoo, tab sis cov txheej qis tsis zoo: theem Sublimation theem tsis tau xaus, thiab theem siab theem nkag mus ua ntej. Qhov no yog sib npaug rau kev nce qib kub ntawm cov phaj phaj ua ntej. Raws li qhov tshwm sim, cov khoom qis dua yog rhaub thiab melted. Kev daws yog kom txuas ntxiv rau sublimation theem lub sijhawm; Yog tias cov khoom lag luam loj dhau, lossis cov tshuaj tiv thaiv kom qhuav cov khoom lag luam loj dhau, thiab cov khoom nqus ntawm lub tshuab nqus tsev nyob hauv qab no tseem yuav ua rau muaj cov khoom lag luam qis dua. Kev daws teeb meem yog txo qhov ntsuas kub ntawm cov phaj ntawm cov phaj thiab nce lub tshuab nqus tsev nyob ntawm lub thawv khov-qhuav.
7. Cov txheej txheej sab saud ntawm cov khoom lag luam tsis zoo, cov txheej txheem qis dua: cov khoom lag luam uas cov khoom lag luam uas ua kom zoo nkauj thaum nws khov, tab sis nws tsis raug kho kom sov. Tsis ntev tom qab cov sublimation pib, cov khoom heats li, thiab qee cov khoom yaj thiab ntsws. Qhov kev poob ntawm cov khoom ua txhaum sab saum npoo av, yog li sublimation lub zog ntawm cov txheej qis ua haujlwm kom zoo. Kev daws teeb meem yog ua kom rov qab kho cua sov thaum khov
8. Kev daws yog nthuav lub sijhawm desorption thiab ziab, siv lub tshuab nqus tsev kho kom haum thiab kho kom tau cov khoom siab nce qib z qhov kub tso cai kub.
9 Piv txwv li, muaj cov tawv tawv hauv cov khoom. Nws tau melted thaum sublimation, uas ua rau kev ziab kom qhuav thiab cov khoom lag luam. Kev daws yog kom tsim nyog txo qhov ntsuas kub ntawm lub nqus dej ntawm lub thawv kom qhuav, lossis txuas ntxiv rau ziab lub sijhawm kom qhuav.
10. Cov Khoom Siv Dej Lub Tshuab Nqus: Thaum Nqus Plua Plav nres, lub tshuab nqus tsev nyob hauv lub raj mis yog qhov zoo, tab sis nws poob nrawm tom qab cia. Nws yuav yog tias tus nres tsheb tsis sib phim lossis lub hau aluminium yog xoob dhau, thiab cov pa xau thiab poob lub tshuab nqus tsev. Kev daws teeb meem yog los hloov lub stopper lossis kho qhov nruj ntawm cov nias tawm txhuas; Nws kuj tseem yog tias cov khoom siv dej yog qhov siab dhau, thiab lub nqus dej ntawm cov dej vapor siab yog daws. Kuj tseem muaj ib qho teeb meem uas tsis muaj dab tsi ua nrog khov-qhuav nkhaus thiab cuam tshuam rau cov khoom lag luam zoo, vim cov roj silicone lossis roj hauv lub khov-qhuav tank.
