Kawm txog kev sib khi ua haujlwm ntawm ampoules rau cov kab mob khov qhuav qhuav

Muaj qee qhov yuav tsum tau ua rau kev tso cov raj ntawm cov kab mob khov-qhuav, thiab qhov loj ntawm lub raj yog nyob ntawm txoj kab uas hla ntawm conical luv raj ntawm ntau ceg. Peb xaiv lub puab txoj kab uas hla ntawm 8 m thiab ib tug iav raj ntawm 110 hli. Cov kev xav tau zoo rau iav yog nruab nrab, thiab alkaline iav tsis tuaj yeem siv. Lawv kev ntxhib los mos thiab hardness muaj qhov zoo thiab qhov tsis zoo. Cov iav mos yog yooj yim rau yaj thiab qhib thaum lub sij hawm rov qab thiab cog qoob loo, tab sis nws yog ib qho yooj yim rau tawg thaum lub sij hawm cia. Cov iav uas muaj siab hardness tsis yooj yim rau yaj los yog qhib, tab sis nws tsis tshua tawg thaum lub sij hawm cia. Lub tuam txhab tuaj yeem xaj los ntawm iav ntau lawm raws li qhov xav tau tiag tiag. Thaum xaiv ampoules, siv 2% ua ntej; Soak lub tsho nrog HCl tov 8 × 10 teev, ces yaug dua nrog dej kais dej. Ntxuav nrog dej distilled 2-3 zaug thiab thaum kawg cua qhuav.
Lub tshuab nqus tsev sealing, tsis hais seb hom khoom siv khov ziab qhuav yog siv, txoj kev sib khi ntawm ampoules los ntawm ampoule melting thiab sealing tshuab yog tib yam. Nyob rau hauv lub tshuab nqus tsev vacuum, lub Upper kawg ntawm ampoule yog melted, tsim ib tug nyias caj dab rau ceev sealing. Tom qab ntawd nws tau nruab rau ntawm ib sab ntawm ntau cov kav xa dej, thiab lub tshuab nqus tsev twj tso kua mis pib. Thaum lub tshuab nqus tsev muaj tseeb yog 0.001 torr, lub foob yog siv rau ntawm lub caj dab nyias. Yog tias lub tshuab nqus tsev tsis tuaj yeem ncav cuag qhov siab qis, ces nws yuav tsum tau kho kom tsawg kawg 0.01 torr.
