Hauv lub neej niaj hnub no, cov khoom siv hlau nplaum tau siv dav, ob qho tib si samarium cobalt khoom thiab neodymium hlau boron cov khoom ua si sib txawv. Rau cov pib tshiab hauv kev lag luam, nws yog ib qho tseem ceeb heev uas yuav tau xaiv cov khoom uas haum rau koj cov khoom. Niaj hnub no, cia peb ua tib zoo saib cov yam ntxwv ntawm ob yam khoom sib txawv thiab pom qhov twg yog qhov tsim nyog rau koj cov kev xav tau.
1. Kev sib piv kev ua haujlwm
Cov khoom sib nqus
NdFeB yog cov khoom siv hlau nplaum uas paub zoo tshaj plaws nrog cov khoom siv hluav taws xob sib nqus siab heev. Qhov no ua rau nws zoo heev nyob rau hauv daim ntawv thov scenarios uas yuav tsum tau muaj zog magnetic teb. Piv txwv li, nyob rau hauv lub teb ntawm motors, motors siv NdFeB mus tas li hlau nplaum tuaj yeem tsim kom muaj zog ntau dua thiab muab lub zog muaj zog rau cov khoom siv. Cov khoom sib nqus ntawm SmCo cov hlau nplaum ruaj khov yuav tsum tsis txhob kwv yees. Lawv muaj peev xwm tuav tau zoo sib nqus stability nyob rau hauv qhov kub thiab txias ib puag ncig. Qhov no feature ntawm SmCo ua rau nws sawv tawm nyob rau hauv ib co tshwj xeeb kev lag luam ib puag ncig uas yuav tsum tau kub kub.
Kub stability
Ib qho zoo tshaj plaws ntawm SmCo cov khoom yog nws qhov kub thiab txias stability. Nyob rau hauv ib puag ncig kub, qhov sib nqus ntawm SmCo cov hlau nplaum ruaj khov yog tsawg dua li ntawm NdFeB. Nyob rau hauv sib piv, txawm hais tias NdFeB muaj zog sib nqus zog, nws qhov kub thiab txias kam rau ua kuj tsis muaj zog, thiab irreversible demagnetization yuav tshwm sim nyob rau hauv high kub.
Corrosion kuj
Nyob rau hauv cov nqe lus ntawm corrosion kuj, SmCo cov ntaub ntawv ua tau zoo nyob rau hauv ib co av noo thiab corrosive gas ib puag ncig vim lawv cov tshuaj muaj zog ruaj khov. Txawm li cas los xij, yog tias cov ntaub ntawv NdFeB tsis muaj cov txheej txheem tiv thaiv tsim nyog, lawv raug cuam tshuam rau corrosion nyob rau hauv ib puag ncig zoo sib xws, cuam tshuam rau lawv cov kev ua tau zoo thiab kev pabcuam lub neej. Txawm li cas los xij, nrog kev txhim kho ntawm cov thev naus laus zis thev naus laus zis, kev txhim kho corrosion ntawm NdFeB kuj tseem maj mam txhim kho.
2. Daim ntawv thov teb
Daim ntawv thov teb ntawm SmCo cov khoom
Samarium cobalt cov khoom siv hlau nplaum ruaj khov yog siv dav hauv cov chaw siab kawg xws li aerospace, tub rog, thiab kev kho mob. Hauv kev tswj hwm ntawm cov tshuab dav hlau, SmCo cov hlau nplaum ruaj khov tuaj yeem ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias thiab kev ua haujlwm ntawm lub tshuab ua kom muaj kev vibration los xyuas kom meej tswj lub cav. Nyob rau hauv lub missile kev taw qhia system thiab tus cwj pwm tswj Cheebtsam ntawm satellites nyob rau hauv cov tub rog teb, SmCo cov ntaub ntawv kuj nyiam rau lawv siab precision thiab siab stability. Hauv cov khoom siv kho mob, xws li qee qhov tseem ceeb ntawm cov khoom sib nqus hauv cov khoom siv sib nqus resonance imaging (MRI), kev siv cov hlau nplaum ruaj khov SmCo ua kom cov khoom siv tau zoo nyob rau hauv lub sijhawm ntev thiab siv zog ua haujlwm.
Daim ntawv thov teb ntawm NdFeB cov khoom
NdFeB cov khoom siv hlau nplaum ruaj khov tau siv dav hauv pej xeem vim lawv cov khoom sib nqus muaj zog thiab tus nqi qis. Piv txwv li, hauv peb cov neeg siv khoom siv hluav taws xob xws li hard drives, cov neeg hais xov tooj ntawm tes, thiab lub mloog pob ntseg, NdFeB cov hlau nplaum ruaj khov muab rau lawv nrog cov hlau nplaum me me thiab muaj zog. Nyob rau hauv lub motors ntawm lub zog tshiab tsheb, daim ntawv thov ntawm NdFeB kuj tau zoo heev txhim kho cov efficiency ntawm lub motors thiab txhawb txoj kev loj hlob ntawm lub tshiab lub zog tsheb kev lag luam. Tsis tas li ntawd, NdFeB tseem ua lub luag haujlwm tseem ceeb hauv ntau lub motors, sensors thiab lwm yam khoom siv hauv kev lag luam automation.
3. Tus nqi tseem ceeb
Tus nqi raw khoom
Cov khoom tseem ceeb ntawm SmCo cov khoom siv hlau nplaum ruaj khov, samarium thiab cobalt, yog cov hlau tsis tshua muaj, thiab lawv cov mining thiab refining nqi siab, uas ua rau cov nqi siab ntawm cov khoom siv raw rau SmCo cov khoom. Ntawm cov khoom tseem ceeb ntawm NdFeB, neodymium, hlau thiab boron, hlau thiab boron yog cov khoom siv thiab pheej yig. Txawm hais tias neodymium tseem yog lub ntiaj teb tsis tshua muaj, NdFeB muaj qee qhov zoo hauv cov nqi raw khoom piv rau SmCo.
Tus nqi ua haujlwm
Thaum lub sij hawm ua, SmCo cov ntaub ntawv yog ib qho nyuaj rau cov txheej txheem vim lawv cov hardness siab thiab lwm yam ntxwv, thiab cov txheej txheem nqi kuj siab. NdFeB cov ntaub ntawv yog ib qho yooj yim rau txheej txheem, tab sis vim lawv yooj yim oxidation thiab lwm yam ntxwv, tshwj xeeb kev tiv thaiv yuav tsum tau thaum lub sij hawm ua, uas kuj nce tus nqi ua rau ib tug tej yam kev mob.
4. Yuav ua li cas xaiv cov khoom tsim nyog rau koj
Xav txog qhov kub thiab txias ua haujlwm
Yog tias cov khoom siv nyob rau hauv qhov kub thiab txias, xws li ntau tshaj 150 ℃ lossis siab dua, xws li nyob ze ntawm qhov kub thiab txias muaj cua sov thiab cov khoom siv sib nqus nyob ib ncig ntawm lub tshuab aerospace, cov khoom samarium cobalt yog qhov kev xaiv zoo dua. Vim tias nws qhov kev ruaj ntseg ntawm qhov kub thiab txias tuaj yeem ua kom ruaj khov ua haujlwm ntev thiab tsis txhob muaj teeb meem demagnetization tshwm sim los ntawm qhov kub thiab txias. Yog tias qhov kub thiab txias ua haujlwm nyob rau hauv chav tsev kub lossis qis dua 100 ℃, xws li cov khoom siv hluav taws xob hauv pej xeem feem ntau, cov khoom siv hluav taws xob dav dav, thiab lwm yam., NdFeB cov khoom tuaj yeem ua tau raws li qhov xav tau thiab tuaj yeem muab kev ua si tag nrho rau lawv cov khoom sib nqus siab.
Xav txog cov kev cai tiv thaiv corrosion
Yog tias cov khoom yuav raug siv nyob rau hauv ib puag ncig ntawm cov av noo, corrosive gas, xws li cov khoom sib nqus hauv cov khoom siv hauv ib puag ncig xws li cov seaside thiab cov nroj tsuag tshuaj, qhov corrosion kuj ntawm cov khoom yuav tsum tau xav txog. Cov tshuaj ruaj khov ntawm samarium cobalt cov khoom nws tus kheej ua rau nws muaj txiaj ntsig zoo dua hauv qhov chaw no. Txawm li cas los xij, yog tias cov khoom lag luam NdFeB raug kho nrog cov txheej txheem tiv thaiv zoo, nws tuaj yeem ua tau raws li qhov yuav tsum tau muaj kev tiv thaiv corrosion rau qee yam. Nyob rau lub sijhawm no, nws yog ib qho tsim nyog yuav tsum ua tib zoo xav txog tus nqi thiab kev tiv thaiv los xaiv.
Ntsuas tus nqi siv nyiaj
Yog tias tus nqi tsis yog qhov tseem ceeb txwv, thiab qhov kev ua tau zoo thiab kev ruaj ntseg yuav tsum muaj siab heev, xws li hauv cov tub rog, cov cuab yeej siv kho mob siab thiab lwm yam kev lag luam, cov khoom zoo thiab ruaj khov ntawm samarium cobalt tuaj yeem ua kom ntseeg tau kev ua haujlwm ntawm cov khoom. khoom siv. Txawm li cas los xij, yog tias nws yog cov khoom lag luam loj hauv pej xeem, kev tswj hwm tus nqi yog qhov tseem ceeb. NdFeB cov khoom lag luam tuaj yeem txo cov nqi zoo thaum ua tau raws li qhov yuav tsum tau ua nrog lawv cov nqi raw khoom tsawg thiab cov nqi ua haujlwm.
Kev lag luam xav tau
Rau qee qhov kev siv uas yuav tsum tau muaj kev sib nqus zoo heev thiab kev ruaj ntseg, xws li cov kev taw qhia missile thiab cov khoom sib nqus hauv cov khoom siv kuaj mob siab, qhov siab precision thiab ruaj khov magnetic kev ua tau zoo ntawm samarium cobalt cov khoom muaj ntau dua nyob rau hauv txoj kab nrog cov kev xav tau. Rau qee qhov kev lag luam zoo tib yam, cov neeg siv khoom siv hluav taws xob, thiab lwm yam uas tsis tas yuav tsum tau muaj qhov tseeb tshwj xeeb tab sis yuav tsum muaj lub zog sib nqus loj dua, cov khoom siv neodymium hlau boron tuaj yeem ua haujlwm zoo.
Tsis muaj qhov sib txawv kiag li ntawm samarium cobalt khoom thiab neodymium hlau boron khoom. Thaum xaiv ob cov khoom sib nqus zoo heev, koj yuav tsum ua kom muaj kev sib piv. Cov kev sib qhia saum toj no vam tias yuav pab txhua tus neeg nrhiav cov khoom uas ua tau raws li lawv cov kev xav tau!
