Dab tsi yog p phaj dawb huv
Nrog nws txawv kev lag luam silverery-dawb luster thiab tshuaj lom neeg lub cev nqaij daim tawv tau dhau los ua "kev lag luam tsis txaus ntseeg" hauv kev lag luam hluav taws xob hauv kev lag luam hauv kev lag luam hlau. Nrog rau cov ntsiab lus npib tsib xee ntau tshaj 99%, cov phaj hlau no tsuas yog ua kom muaj qhov ua kom zoo tshaj plaws, tab sis kuj tseem ua tau zoo tshaj qhov ua tau zoo los ntawm precision machining machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising machising.
Txhais thiab kev faib tawm ntawm Phaj Xib Npib: kev ua ke zoo tshaj ntawm kev ua kom huv siab thiab ntau haiv neeg
Ntshiab tsibickel phaj yog tsim los ntawm electrolytic npib tsib xee lossis high-purity npib tsib xee los ntawm lub tshuab hluav taws xob melting thiab dov. Raws li cov qauv thoob ntiaj teb (xws li ASTM B162 thiab GB / T 2054), nws cov khoom lag luam tsib) khav theeb cov qib tshaj li 99.9%. Qhov kev ua siab zoo no nthuav dav nws los ntawm Nickel Alloy Daim Hlau, ua rau nws lub cuab yeej muaj zog hauv cov corrosion resistance. Ntshiab Nickel Phaj tuaj yeem muab faib ua cov qib siab thiab cov qib nyuaj raws li kev ua haujlwm:
Annealed: High-kub-kub animinates sab hauv kev ntxhov siab, ua rau kev ua haujlwm zoo, ua kom haum rau cov txheej txheem sib sib zog ua xws li kev sib sib zog nqus thiab dabtsi yog khoov.
Hardened: Txias-dov thiab muaj zog, nws hardness yog nce los ntawm ntau dua 30%, cia nws siv ncaj qha rau hauv kev tsim cov vaj huam sib luag.
Tsis tas li ntawd, raws li cov txheej txheem kho mob saum npoo av, lub phaj tsib dawb tuaj yeem faib ua pickled, polished, thiab coated cov kev xav tau ntawm cov chaw sib txawv.
Cov yam ntxwv tseem ceeb ntawm lub phaj ntshiab npib tsib xee: "trifecta" ntawm corrosion tsis kam, kub tawm tsam, thiab hluav taws xob cuam tshuam, thiab hluav taws xob cuam tshuam, thiab hluav taws xob ua haujlwm
Corrosion Kuj: Ib "ntuj thaiv kev" rau ib puag ncig Alkaline
Ntshiab npib tsib xee cov khoom ua kom pom tseeb hauv cov kev daws teeb meem alkaline. Kev sim cov ntaub ntawv qhia tau hais tias hauv 50% npau npau sodium hydium ntsuas, feem ntau cov kev ua kom huv siab txhua xyoo yog tsawg dua 25 feem kaum tias ntawm cov hlau tsis huv. Cov xeeb ceem no vim yog cov nibel oxide (NIO) cov yeeb yaj kiab tiv thaiv tau tsim rau ntawm nws cov npoo av, uas thaiv kev nkag mus ntawm corrosive media xws li chloride ions thiab sulfides. Piv txwv li, hauv Chlor-Alkali Kev Lag Luam, electrolytic cell forma ua los ntawm lub peephel cell
Thaum tshav kub kub tiv: ib qho stabilizer rau qhov chaw kub siab
Ntshiab Nickel muaj lub ntsiab lus melting ntawm 1455℃thiab ib tus lej oxidation tsawg kawg nkaus hauv qab 600 degree. Hauv kev lag luam AERPACACE, Phaj Npib Tsib yog siv los tsim cov kev sib txuas sib txuas ntawm cov ntaub pua chaw thiab cov dav hlau cav. Nws coefficient ntawm thermal expansion tsuas yog ib nrab ntawm cov hlau, tiv thaiv cov ntawv tsis ua haujlwm tshwm sim los ntawm kev kub ntxhov. Tsis tas li ntawd, npib dawb huv tau tswj hwm nws qhov kev cuam tshuam ntawm tsawg, nrog nws cov kev cuam tshuam nyuaj ntawm -196℃hauv cov kua dej ua kua rau ntawm chav-txias roj carbon hlau.
Conduction: ib qho "tsis pom hlau" hauv cov khoom siv hluav taws xob
Ntshiab Nickel muaj qhov tiv taus tsuas yog 6.84 · li (ntawm 20 degree), nce qib siab ntawm tooj liab. Cov cuab yeej no ua rau nws cov khoom siv zoo rau cov roj teeb thiab cov khoom siv hluav taws xob. Piv txwv li, siv cov ntshiab npib nickel ntawv ci rau cov chaw tsis zoo ntawm cov npib tsib xee hluav taws xob tam sim no tuaj yeem txo cov roj teeb sab hauv los ntawm 15%, txhim kho kev nce qib thiab kev tawm haujlwm. Nyob rau hauv high-voltage hloov pauv, cov neeg hu dawb npib uas muaj kev sib cuag ruaj ntseg tsis kam tom qab 100,000 voj voog, deb tshaj 50,000 caum cov nyiaj sib cuag.
Cov Kev Siv Cov Kev Siv Lub Npib Tsib Xee Npib Tsib: Los Ntawm Cov Hluav Taws Xob Hluav Taws Xob
Cov Khoom Siv Tshuaj: Tus "Tus Saib Xyuas" tawm tsam corrosive media
Nyob rau hauv cov pa roj acid muaj xws li sulfuric acid, cov roj ntsha hydrocoric, ntim ua kom muaj cov phaj ntshiab tuaj yeem hloov cov roj titanium ntau, txo tus nqi los ntawm ntau dua 40%. Cov ntaub ntawv los ntawm lub tuam txhab tshuaj lom neeg qhia tau hais tias ib lub taub hau npib tsib xee ua haujlwm tsis tu ncua, thaum lub 316L stainless hlau nthuav qhia pitting corrosion tom qab ob xyoos nkaus xwb.
Kev Lag Luam Kev Lag Luam Nuclear Lub Zog: Tus Txheej Txheem Qis "hauv hluav taws xob ib puag ncig
Ntshiab tsibickel phaj (xws li N6) tau siv dav hauv qhov tseem ceeb ntawm kev ua haujlwm siab thiab tswj hwm kev ua haujlwm tsis zoo rau hluav taws xob o. Piv txwv li, cov cladding roj ua los ntawm cov ntshiab lub phaj nyob rau hauv Tuam Tshoj lub neej tsis muaj zog ntawm 10-xyoo ntawm 10²¹ neutrons / cm² ntawm cov tsoos zirconium alloys.
Cov Khoom Siv Hluav Taws Xob: Lub Tsev Tsim "Lub Tsev Tsim" ntawm Kev Tsim Kho Mob
Hauv 5G Kev Sib Txuas Lus, Ntshiab Nickel Ntawv Nyiaj yog cov khoom siv tseem ceeb rau cov lim dej siab. Nws cov khoom poob qis tuaj yeem txhim kho cov paib kev kis tau teeb liab kev ua tau zoo los ntawm 20%. Hauv cov kev lag luam semiconduct, cov hom phiaj npib tsib xee siv hauv cov txheej txheem uas muaj peev xwm ua tau zoo dua lossis muaj sib npaug ntawm cov khoom siv 7nm ntawm 7nm kev tsim khoom.
Cov Khoom Noj Ua Noj: Tus kws kho mob ntawm cov qauv kev nyab xeeb
Ntshiab npib tsib xee lub phaj, ua cov tsis muaj tshuaj lom thiab tsis sib nqus, tau pom zoo FDA-tau pom zoo rau kev siv hauv cov khoom noj hauv zaub mov. Piv txwv li, lub tuam txhab siv miskas cov pasteurizer, ua haujlwm siv cov phaj tsib ntshiab, tau ua tsis tu ncua ntawm 140℃rau peb xyoos yam tsis tau tso tawm cov hlau ions, kom muaj kev nyab xeeb khoom.
Los ntawm cov roj tob-dej kom muaj cov phiaj xwm chaw, los ntawm cov khoom siv npe npe, muaj kev sib xyaw ua ke ntawm lub tsev, tau dhau los ua lub tsev tsis tseem ceeb rau kev lag luam niaj hnub. Nrog rau kev loj hlob sai ntawm lub zog tshiab, semiconductor thiab lwm yam kev lag luam, qhov kev thov rau cov kab mob Nickel loj zuj zus ntawm 8%.
