Peb tau tham txog cov kauj ruam cuam tshuam nrog tsim cov hlau nplaum neodymium, nrog qee cov ntawv sau txog dab tsi qhov no qhia rau cov neeg siv khoom sib nqus tiag.
1. Cov ntaub ntawv tseem ceeb
Cov qauv sib xyaw ua ke rau feem ntau ntawm Neodymium hlau nplaum yog Nd2Fe14B. Tab sis tiag tiag cov khoom lag luam, cov saw hlau tuaj yeem ua ntau ntau qhov nyuaj. Ntawm no yog qhov feem ntau ua rau siv tshuaj tiv thaiv:
57 Fe + 8 B + 10 Fe2O3 + 7.5 Nd2O3 + 52.5 Ca -> Nd15Fe77B8 + 52.5 CaO
Lub tshuab nqus tsev Induction cua sov tsim
Dab tsi peb yuav tsum them sai sai yog qib siab dua hlau nplaum qib kawm, ntxiv | muaj feem nrog. Thaum cov feem pua me me ntawm Cov Hlau (Fe) tau hloov nrog Cobalt (Co), lub zog ntawm cov hlau nplaum yuav txhim khu ntawm qhov kub nce siab, txawm li cas los xij kev sib zog yuav ua kom tsawg dua. Yog tias qhov chaw me me ntawm Neodymium (Nd) hloov pauv nrog Dysprosium (Dy), qhov sib zog ua kom muaj zog yog qhov ua kom zoo dua, txawm li cas los xij cov khoom siv ntau tshaj plaws (BHmax, ib kauj ruam zoo heev ntawm cov hlau nplaum hluav taws xob) qis qis. Li qub, cov neeg tsim khoom siv hlau nplaum siv ob qho Co thiab Dy ua ke. Li ntawd lub zog thiab kev ua tau zoo yuav zoo kawg.
2. Melting
Txhawm rau tiv thaiv cov khoom. Hauv kev tsim khoom, cov khoom siv xav tau tshwm sim hauv lub tshuab nqus tsev lub tshuab cua sov. Lub kaw lus tso cua sov los ntawm hluav taws xob hloov kab hluav taws xob ntawm nws, lub tshuab nqus tsev tuaj yeem ua rau cov pa paug tawm ntawm ntau lawm.
3. Kev Tsim Milling
Txhawm rau ua kom cov khoom siv mus rau 3mm ， cov khoom siv hlau nplaum yuav siv lub dav hlau milling pauv hloov rhas magnetizationial txoj cai los ua hmoov uas muaj qhov loj me me tiag tiag.
4. Nias
Sib Ntaus Kev Ua
Cov hmoov yuav tsum tau sib koom ua ke txhawm rau txhawm rau tsim cov duab uas muaj qhov sib txawv magnetization. Hauv kev tsim khoom, raug xa mus rau kev ua kom zoo siab tuag, cov hmoov txhuam yog nias nrog txoj cai tuag rau hauv lub cev lub cev ntawm qhov kub tau nce txog ntawm 725 ° C. Cov khoom yog tom qab uas tau tso rau hauv qhov tuag thib 2, qhov uas nws tau nias rau a daim ntawv loj dua uas tau ua nrog tsib caug feem pua nws pib nce. Qhov no ncaj txoj kev nyiam qhov kev taw qhia ntawm lub zog txuas nrog tus nias taw qhia. Rau qee hom ntawv, muaj cov kev ua uas muaj qhov sib txuas uas tsim ib qho hluav taws xob teb thoob plaws kev thawb mus ua kab cov xaim.
5. Kev ua txhaum
Sintering yog txheej txheem ib txwm nyob hauv cov hmoov metallurgy. Cov khoom tseem ceeb yog nias ntawm nce ntawm qhov kub thiab txias (kom txog li 1080 ° C) hauv qab ntawm cov khoom tso tawm, txog thaum nws cov kab mob sib xyaw ua ke.
6. Machining
Cov hlau nplaum sintered tau txo mus rau cov neeg siv khoom xav ua daim ntawv ua siv cov txheej txheem kev sib tsoo. Ntau feem ntau tsawg dua, cov ntawv nyuaj yog tsim nrog hluav taws xob paug machining (EDM). Raws li qhov txiaj ntsig ntawm cov khoom siv siab, cov khoom siv poob vim tias cov machining tau tswj hwm qhov tsawg kawg nkaus. Tsis muaj txoj hau kev siv tau los siv cov khoom pov tseg rov qab tiag tiag tau tsim.
7. Txheej Txheem
Cov hlau nplaum tshwj xeeb yog cov hluav taws xob hluav taws xob nrog 3 khoom siv: nickel & tooj liab & npib tsib xee. Qhov no yog qhov tseem ceeb vim qhov tseeb tias qhov tsis muaj xim neodymium cov hlau nplaum yog qhov yooj yim rau "xeb", thiab tseem yuav plam lawv lub zog sib nqus hauv cov tim khawv niaj hnub.
8. Hlau nplaum
Tam sim no, cov hlau nplaum tau qhia tshwj xeeb
ntawm magnetization, txawm li cas los xij, lawv tsis muaj hlau nplaum. Lawv muab tso rau hauv kev txhaj tshuaj pwm (peb tseem hu ua nws lub zog ua kom sib luag) uas yuav qhia tau lub hlau nplaum rau thaj chaw hluav taws xob tsis tshua muaj rau ib pliag. Nws ib txwm muaj peev txheej loj ntawm cable ncig ntawm cov hlau nplaum (s). Cov cuab yeej siv hluav taws xob sib txawv ua rau siv cov txhab nyiaj ntawm cov capacitors raws li lub zog hluav taws xob kom tau txais qhov loj tam sim no rau kev faib tawm ib ob.
9. Kev Soj Ntsuam
Txog qhov zoo ntawm cov hlau nplaum sib tw yog qhov kuaj xyuas. Rau ib chav ntawm cov khoom.
p ntsuas ntsuas hluav taws xob tshaj tawm cov ntsuas. Lub tuab ntawm txheej, thiaj li kuaj xyuas nws, yuav siv hluav taws xob xoo fluorescence niaj hnub thev naus laus zis los kuaj.
Dab tsi txhua qhov no qhia rau cov neeg siv ntawm neodymium hlau nplaum
Lub hlau nplaum nrog cov nickel plating khawb tawm, kom pom qhov khoom siv NdFeB cov hlau nplaum hauv qab no
Neodymium hlau nplaum yog tsim los ntawm cov hmoov hlau ua cov txheej txheem. Lawv cov ntsiab lus zoo li zoo ib yam li tej hub, hloov hlau. Lawv tsis yooj yim siv lub tshuab, yog li peb tsis hais kom sim ua kom lawv.
Neodymium hlau nplaum yog qhov nyuaj heev thiab yooj yim. Txawm hais tias cov hlau zoo li lawv cov npib tsib xee, lawv tsis zoo li cov hlau. Yog tias ua raws li cov kev xav tau ntse, xws li ua kom lawv khob txoj hauv kev sib raug zoo, lawv tuaj yeem tawg sai lossis puas. Kev kho, nrog rau kev coj kom yog, yog tsim nyog}.
Peb tsis hais kom haum xovxwm neodymium hlau nplaum. Hlau nplaum yog nquag glued mus rau hauv lub hnab tshos uas muaj me ntsis loj dua cov hlau nplaum, hloov tsis txhob nias-ntsej muag.
Peb tsis hais kom ua kev siv lub xov hlau nplaum. Thaum nws tseem ua tau los txo cov hlua, lawv tsis sawv zoo hauv qab qhov ntaws.
