Material Matters – Xaiv txoj cai sheath rau -40℃Ib-End Cartridge rhaub
Lub plhaub ntawm lub tshuab rhaub cartridge yuav zoo li lub raj hlau yooj yim. Hauv kev muaj tiag, nws yog thawj kab ntawm kev tiv thaiv ib puag ncig kev puas tsuaj-thiab ntawm -40 degree, kev xaiv ntawm cov ntaub qhwv tuaj yeem txiav txim siab seb lub tshuab cua sov puas siv tau ntau xyoo lossis ua tsis tiav hauv lub lis piam.
Kev xaiv tus qauv: Stainless hlau 304
Stainless hlau 304 yog cov khoom siv ntau tshaj plaws rau cov khoom siv hluav taws xob. Nws muaj qhov zoo oxidation tsis kam thiab siab - qhov kub thiab txias, ua rau nws haum rau feem ntau cov chaw lag luam. Rau ntau daim ntawv thov saum toj no khov, 304 ua haujlwm zoo kawg nkaus.
Tab sis cov xwm txheej hauv qab -40℃xav tau ntau dua. Thaum 304 stainless hlau ua tau zoo txaus nyob rau hauv ntau qhov chaw txias, raug rau cov kua nitrogen los yog huab cua thermal cycling yuav tsum tau zoo metallurgical kev ua tau zoo.
Kev Txhim Kho: Stainless Hlau 316
Stainless hlau 316 muab kev tiv thaiv corrosion zoo tshaj thiab tswj cov khoom siv kho kom zoo dua ntawm qhov kub thiab txias. Tsis zoo li qee cov alloys, nws tsis ua nkig hauv qhov txias. Rau cov ntawv thov cuam tshuam nrog cov tshuaj, ntsev, lossis lwm yam tshuaj corrosive, 316 muaj txiaj ntsig zoo.
Hauv kev kho mob thiab kev tshawb fawb, stainless hlau 316L nrog electropolished nto ua tau raws li USP Class VI biocompatibility cov txheej txheem thiab tiv taus hnyav sterilization txoj kev nrog rau autoclaving thiab tshuaj sterilants. Qhov no ua rau nws qhov kev xaiv zoo tshaj plaws rau cov chaw muag tshuaj txias, cov khoom siv hauv txhab nyiaj, thiab cov cuab yeej kuaj mob.
Kev xaiv hwm: Inconel Alloys
Rau cov ntawv thov uas xav tau tshaj plaws -kua nitrogen raug, thermal cycling hnyav, lossis corrosive ib puag ncig-Inconel 600 lossis 800 series alloys sawv cev rau qhov kev xaiv zoo tshaj plaws. Cov alloys no ua haujlwm thermal cycling thiab hnyav hnyav dua li cov hlau tsis muaj steel, txawm tias lawv raug nqi ntau dua.
Inconel sheaths suits cryogenic qauv cia daim ntaub ntawv qhov twg cov cua sov yuav tsum ua hauj lwm ntawm qhov kub thiab txias ze rau -196℃thaum tawm thiab sai cua sov mus rau +50℃los yog siab dua thaum nyob rau. Qhov no 250℃kub viav vias yuav tsum tshwm sim ntau zaus yam tsis muaj khoom degradation.
Cov Hlau Resistance Sab hauv
Lub sheath tiv thaiv cov khoom siv sab hauv, tab sis cov khoom no yuav tsum tau ua thaum txias. Cov hlau tsis kam, feem ntau yog npib tsib xee-chromium alloy xws li NiCr 80/20, yuav tsum ua kom pom cov khoom hluav taws xob ruaj khov thoob plaws tag nrho qhov kub thiab txias. Qhov tseem ceeb tiv thaiv yuav tsum nyob twj ywm tsis tu ncua seb cov hlau pib los ntawm cov kab mob cryogenic lossis ua haujlwm ntawm qhov ntsuas kub siab tshaj plaws.
Cov Txheej Txheem Txheej Txheem
Nruab nrab ntawm cov hlau tsis kam thiab cov ntaub qhwv yog siab -purity magnesium oxide rwb thaiv tsev. Cov khoom siv no ua haujlwm rau ob lub hom phiaj tseem ceeb: nws insulates lub kauj los ntawm cov hlau sheath (tiv thaiv luv luv Circuit Court) thiab ua kom muaj cua sov zoo los ntawm lub kauj mus rau hauv lub plhaub. The filler is densely compacted during manufacturing to eliminate air gaps that would reduce heat transfer.
Thaum -40 degree, qhov purity thiab compaction ntawm cov khoom siv rwb thaiv tsev no tseem ceeb heev. Txhua qhov dej ntws tawm thaum lub sijhawm tsim khoom tuaj yeem khov thiab nthuav dav, ua rau cov yam ntxwv ntawm dielectric los yog ua rau cov pob txha tawg hauv cov ntaub.
Daim ntawv thov -Kev txiav txim siab tshwj xeeb
Cov ntawv thov sib txawv xav tau cov ntaub ntawv sib txawv:
Agricultural av cua sovFeem ntau siv watt ntom ntom ntawm 5-7 W / cm² kom ruaj khov av kub yam tsis muaj cua sov cov cag qoob loo
Kev kho mob txias ciaxav tau cov ntaub ntawv uas ua tau raws li cov qauv biocompatibility thiab tiv taus kom tsis muaj menyuam
Aerospace xeemxav tau cov ntaub ntawv uas tswj kev ncaj ncees los ntawm huab cua kub cycling
Pharmaceutical freeze dryingxav tau cov ntaub ntawv sib xws nrog lub tshuab nqus tsev thiab cryogenic
Kab hauv qab
Kev xaiv cov khoom siv rau -40℃cartridge heaters tsis yog ib qho -loj- haum- txhua qhov kev txiav txim siab. Stainless hlau 304 ua haujlwm rau ntau daim ntawv thov, tab sis 316 muaj kev tiv thaiv corrosion zoo dua thiab kev ua haujlwm txias-kub. Inconel alloys muab qib siab tshaj plaws ntawm kev ua tau zoo rau qhov xav tau tshaj plaws. Qhov kev xaiv nyob ntawm qhov kev thov tshwj xeeb, suav nrog qhov kub thiab txias, raug tshuaj lom neeg, thermal cycling zaus, thiab cov qauv kev cai.
Ib qho - lub taub hau cartridge rhaub nrog 5-7 W / cm² watt ceev thiab cov ntaub ntawv sheath tsim nyog muab kev ua tau zoo rau feem ntau cov kev siv kub kub. Tab sis thaum kub poob mus rau -40℃thiab qis dua, xaiv cov khoom siv los ua ib qho tseem ceeb hauv kev ntseeg tau ntawm lub cev.
