Tsawg-Kev Ruaj Ntseg Kub Kub: Yuav ua li cas 5-7g / cm³ Cartridge Heater ntom ntom kom tsis txhob muaj qhov tshwm sim ntawm -50 degree
Hluav taws xob to thiab rwb thaiv tsev attenuation yog zais kev nyab xeeb kev phom sij uas plague ultra-tsawg kub muaj cua sov tshuab. Ntau lub Hoobkas kev soj ntsuam kev nyab xeeb pom tau tias cov khoom siv cua sov ua haujlwm hauv -40℃rau -50℃ib puag ncig tau txo cov rwb thaiv tsev tom qab lub sijhawm ua haujlwm, uas yooj yim ua rau cov khoom siv tiv thaiv kaw thiab txawm tias hluav taws xob muaj kev nyab xeeb. Industry data shows that unreasonable internal powder density is the primary cause of insulation failure of single-ended heating tubes in ultra-low temperature environments.
Ordinary cartridge heaters nrog qhov ntom qis dua 5g / cm³ muaj cov txheej txheem rwb thaiv tsev xoob xoob nrog ntau qhov sib txawv me me. Nyob rau hauv ultra- qhov kub thiab txias siab - cov av noo nyob ib puag ncig, huab cua txias nqa dej vapor txuas ntxiv nkag mus rau sab hauv ntawm lub raj cua sov los ntawm qhov khoob. Ntawm -50 degree, cov dej vapor condenses rau hauv Frost thiab adheres rau saum npoo ntawm cov cua sov hlau thiab cov hmoov rwb thaiv tsev. Tom qab rov ua lub zog ntawm cov cua sov thiab kaw lub voj voog khov, cov Frost melts thiab khaws cov dej me me, uas maj mam rhuav tshem cov rwb thaiv tsev ntawm magnesium oxide hmoov, ua rau tsis tu ncua ntawm rwb thaiv tsev tiv thaiv thiab thaum kawg hluav taws xob to thiab luv luv Circuit Court.
Ultra- qhov kub tsis tshua muaj siab rau ib leeg- tas cov cartridge tso cua sov nruj me ntsis tswj cov cartridge rhaub kom ceev ntawm 5-7g/cm³ los tsim kom muaj kev ruaj ntseg thiab txhim khu kev qha. High-siab compaction technology tshem tawm tag nrho cov qhov khoob hauv lub raj cua sov, tag nrho thaiv qhov nkag mus ntawm sab nraud Frost thiab dej vapor. Kev hloov kho siab -purity magnesium oxide hmoov siv tau muaj kev ua tau zoo super hydrophobic thiab qis- qhov kub thiab txias kev ruaj ntseg, thiab yuav tsis nqus dej los yog tawg thiab loosen nyob rau hauv ntev -lub sij hawm -50℃low-temperature freezing. Kev tshuaj ntsuam xyuas qhia tau hais tias tom qab 12 lub hlis ntawm kev ua haujlwm tas mus li hauv -50℃huab cua ib puag ncig, kev tiv thaiv kev tiv thaiv ntawm 5-7g / cm³ ntom cartridge heaters tseem nyob saum 1000MΩ, uas deb tshaj qhov kev nyab xeeb kev lag luam.
Ntxiv nrog rau qhov kev ua kom zoo dua qub, ntau cov txheej txheem rwb thaiv tsev ntxiv tau ntxiv rau ultra- cov cua kub cua kub qis rau cov xwm txheej txias heev. Lub davhlau ya nyob twg tau txais ob npaug - txheej qis- kub resistant insulating lub tes tsho thiab tag nrho cov kua nplaum puv txheej txheem los tiv thaiv Frost infiltration los ntawm kev sib kis. Cov txheej txheej yog polished thiab kaw seamlessly kom tsis txhob muaj huab cua sab nraud nkag mus rau hauv lub raj lub cev los ntawm qhov khoob me me. Cov hlau cua sov sab hauv yog qhwv nrog siab - kub thiab qis - kub resistant insulating txheej los tsim ib tug dual rwb thaiv tsev tiv thaiv qauv nrog compacted magnesium oxide hmoov.
Hom -density ultra- low temperature cartridge rhaub no yog dav siv nyob rau hauv qis- kub muaj xwm txheej uas yuav tsum tau muaj kev nyab xeeb. Cov tshuaj tsis tshua muaj- cov khoom siv tub yees kub, khoom noj khoom haus ultra- cov khoom siv hluav taws xob txias txias ua haujlwm, thiab cov khoom siv kho mob cryogenic preservation auxiliary cua sov txhua yam xav tau cov pa tawm- pov thawj thiab siab - cov khoom siv rwb thaiv tsev kom muaj kev nyab xeeb ntawm kev tsim khoom thiab kev ua haujlwm. Cov xwm txheej no nyob rau hauv qis - qhov kub thiab txias - qhov chaw nyob rau lub sijhawm ntev, ua rau cov kev xav tau siab heev ntawm kev tiv thaiv kev ruaj ntseg ntawm lub tshuab cua sov.
Kev saib xyuas txhua hnub thiab kev xaiv cov txheej txheem tuaj yeem zam qhov tsis ua haujlwm ntawm cov khoom siv hluav taws xob tsawg ntawm -cov cua kub cua sov. Thaum yuav cov cartridge rhaub rau -50℃ua hauj lwm tej yam kev mob, ua ntej cov khoom uas muaj cartridge heater ceev cim 5-7g/cm³ thiab ua kom tiav cov ntaub ntawv ntsuas kub qis. Tsis txhob txhim kho cov cua kub hauv cov qhov dej ntub dej thiab cov dej khov-accumulating installation qhov, thiab ua kom lub installation ib puag ncig qhuav thiab kaw. Ua kev ntsuas kev tiv thaiv kev tiv thaiv peb lub hlis twg kom tshem tawm cov kev laus thiab tsis ua haujlwm cua sov raws sijhawm.
Kev ruaj ntseg rwb thaiv tsev kev ua tau zoo nyob rau hauv -50℃ultra- qhov kub thiab txias yog sib cais los ntawm tus qauv 5-7g/cm³ cartridge rhaub kom ceev tsim. Tsawg-cov cua kub uas tsis tsim nyog muaj peev xwm muaj peev xwm muaj kev nyab xeeb nyob rau hauv qhov chaw txias heev thiab tsis tuaj yeem ua tau raws li cov qauv kev lag luam kev nyab xeeb. Qhov sib txawv qis- qhov kub thiab txias muaj qhov sib txawv muaj qhov sib txawv ntawm cov av noo thiab kev sib khi, yog li kev tsim qauv kev nyab xeeb ntawm cov cua sov yuav tsum tau ua kom muaj kev nyab xeeb thiab ruaj khov ua haujlwm ntev ntawm cov cua sov.
