Qhov tseeb tiag, lub sijhawm khaws cov cua sov ntawm lub tshuab nqus tsev -insulated flask nyob ntawm tus qauv ntawm lub khob lub cev thiab lub thickness ntawm cov khoom siv.
Feem ntau hais lus, cov khoom siv thinner, lub sij hawm khaws cia ntev dua. Txawm li cas los xij, cov ntaub ntawv nyias nyias ua rau lub cev lub cev muaj zog ntau dua rau kev puas tsuaj thiab deformation, uas tuaj yeem ua rau nws lub neej ua haujlwm luv. Kev ntsuas xws li txheej txheej txheej ntawm cov hlab ntsha sab hauv nrog cov yeeb yaj kiab hlau nyias lossis tooj liab plating tuaj yeem txhim kho cov cua sov. Flasks uas muaj peev xwm loj thiab qhov qhib nqaim zoo li khaws cov cua sov ntev dua, thaum cov muaj peev xwm me me thiab qhov qhib dav khaws cua sov rau lub sijhawm luv. Lub neej kev pab cuam ntawm lub tshuab nqus tsev vacuum kuj yog nyob ntawm qhov huv ntawm lub nkoj sab hauv thiab lub sijhawm ntawm lub tshuab nqus tsev extraction txheej txheem; qhov tseem ceeb tshaj plaws, nws nyob ntawm tus qauv ntawm lub tshuab nqus tsev vacuum.
Cov khoom siv nqus tsev vacuum siv hauv kev lag luam poob rau hauv ob pawg tseem ceeb suav nrog plaub yam tshwj xeeb: lub tshuab nqus tsev tso pa (rau "tipped" lossis "haus-tubed" flasks) thiab lub tshuab nqus tsev vacuum. Lub tshuab nqus tsev vacuum brazing furnaces tau muab faib ua ib zaug -chamber, ntau-chamber, thiab siab-ceev ntau-chamber hom.
Qhov ib zaug -chamber ib leeg lub tshuab nqus tsev brazing rauv muaj lub tshuab nqus tsev nqus nqus ntev ntev; Yog tias lub chaw tsim khoom luv luv rau lub sijhawm no los txhawb kev tsim khoom, lub raj mis lub neej kev pabcuam yuav raug cuam tshuam - feem ntau txwv nws mus txog yim xyoo. Hais txog "tipped" lub tshuab nqus tsev vacuum (tsim siv cov chaw tso tawm), cov cua kub thaum lub sij hawm rho tawm yog kwv yees li 500 degree. Thaum lub plhaub sab nraud tsis tshua muaj kev deformation, lub raj tooj liab lub qhov sib txuas ntawm cov welded yog yooj yim rau kev cuam tshuam - vim yog cov xau, xav tau kev tiv thaiv tshwj xeeb thaum lub sij hawm ib nrab - cov khoom tiav.
Lwm pawg loj yog txoj kev nqus brazing rauv, uas suav nrog peb hom sib txawv. Nws tuaj yeem ua rau xav tsis thoob, tab sis txawm hais tias lub tshuab nqus tsev- insulated flasks peb siv niaj hnub zoo tib yam rau cov qauv insulated flasks nyob rau sab nraud, lawv cov txheej txheem tsim yog ntau nyuaj thiab technically xav tau. Yog li ntawd, lub tshuab nqus tsev- insulated flasks raug nqi tsawg kawg yog ob zaug ntau npaum li cov qauv insulated flasks.
