Khob Magnetsyog ib qho tseem ceeb ntawm lub neej. Lawv yuav tsum muaj nyob rau hauv ntau lub lag luam, tsev kawm ntawv, tsev, thiab kev lag luam. Neodymium khob hlau nplaum yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig nyob rau niaj hnub no. Nws muaj ntau yam kev siv hauv cov khoom siv thev naus laus zis niaj hnub no. Cov khoom no, ua los ntawm hlau, boron, thiab neodymium (tsis tshua muaj-lub ntiaj teb lub caij), yog siv nyob rau hauv cov xwm txheej uas yuav tsum tau ntxiv zog thiab durability.
Txawm hais tias nws qhov me me, nws muab qhov siab tshaj plaws sib nqus zog thiab lub zog. Txawm hais tias raug kub hnyiab, nws khaws nws lub zog.Neodymium los yog NdFeB hlau nplaumtsis txhob corrode thaum coated. Lawv tuaj yeem ua rau hauv lub khob zoo nkauj lossis lub lauj kaub.
Cov kws tshawb fawb txhawj xeeb txog lub ntiaj teb uas tsis muaj cov khoom siv tsawg-lub ntiaj teb no vim yog vim li cas. Txawm hais tias nws yog mined hnyav heev hauv Suav teb, nws tsis tshua muaj nyob hauv Tebchaws Meskas, qhov twg cov kws tshawb fawb ci ntsa iab tuaj yeem pom. Nws muaj ob peb yam ntxwv uas ua rau nws tsim nyog hauv kev tsim cov hlau nplaum:
• Cov khoom siv Neo yuav tsum muaj qhov kub thiab txias los ua haujlwm hauv cov ntawv siv cua sov, tab sis nws yuav xav tau cov cua sov siab heev (lub Curie kub) kom poob nws cov hlau nplaum. Raws li qhov tshwm sim, nws paub tias yuav tiv taus ntau yam demagnetization.
• Cov hlau nplaum neodymium yuav corrode yooj yim yam tsis muaj txheej, thiab xeb tuaj yeem cuam tshuam nrog nws lub peev xwm mus sij hawm ntev los muab kev pom zoo zog.
• Nws yog pheej yig.
• NdFeB xav tias muaj ntau lub zog txawm tias nws me me.
Neodymium khob hlau nplaum, zoo li lwm yam khoom tsim los ntawm tib neeg, muaj qhov muag tsis pom kev. Lawv tuaj yeem, piv txwv li, muaj cov kab plaub hau tawg, txiav me me, lossis porosity. Cov flaws no muaj nyob rau hauv sintered metallic neo khob hlau nplaum. Cov hlau nplaum nyob rau hauv nqe lus nug tseem tuaj yeem ua haujlwm yog tias tsis muaj ntau tshaj 10% ntawm qhov chaw yog chipped.
Tsis tas li ntawd, cov kab nrib pleb tau txais yog tias lawv thaj chaw saum npoo tsis tshaj tsib caug feem pua ntawm cov ncej saum npoo. Rau cov khoom siv nias, kev kam rau siab ntawm thickness los yog magnetization kev taw qhia yuav tsum yog ntxiv los yog minus.005. Lwm qhov ntev yuav tsum yog ntxiv lossis rho tawm.010 raws li IMA cov qauv.
Muaj ntau ntau qhov sib txawv tsim rau lub lauj kaub hlau nplaum thiab electromagnets, nrog rau lub tiaj, threaded bush, threaded stud, countersunk qhov, los ntawm lub qhov, thiab threaded qhov. Muaj ib txwm muaj cov hlau nplaum uas ua haujlwm rau koj daim ntawv thov vim tias muaj ntau yam qauv kev xaiv.
Lub tiaj ua haujlwm tiaj tus thiab tsis muaj qhov tsis pom qhov chaw lav qhov zoo tshaj plaws sib nqus tuav quab yuam. Nyob rau hauv cov xwm txheej zoo tagnrho, nyob rau sab, ntawm ib daim ntawm qib 37 steel uas tau flattened mus rau ib lub thickness ntawm 5 hli, tsis muaj qhov sib txawv ntawm huab cua, cov kev tuav tuav tau raug ntsuas. Tsis muaj qhov sib txawv ntawm qhov kos yog ua los ntawm qhov tsis xws luag hauv cov khoom sib nqus.
Txawm hais tias cov khoom siv hlau nplaum neodymium tuaj yeem ua rau chipping thiab tawg, cov kws tshawb fawb siv nws ntau yam kev siv, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov khoom siv thev naus laus zis niaj hnub no.
Lawv yog siv nyob rau hauv kev tsim khoom ntawm lub computer tseem ceeb xws li tshuab luam ntawv thiab hard disks / tsav.
Tsis tas li ntawd, NdFeB hlau nplaum yog siv los ntawm cov tuam txhab tsim khoom siv suab paj nruag xws li microphones, headphones, thiab hais lus.
Mechanical engineers uas tsim ntau hom motors xav tau cov khoom siv txuj ci no thiab.
Txawm hais tias lub khob neodymium hlau nplaum muaj qhov sib nqus siab, nws tau yooj yim tawg hauv nws daim ntawv ntshiab. Yog li ntawd, yuav tsum tau saib xyuas thaum tuav cov hlau nplaum no. Yog tias cov hlau nplaum neo raug cuam tshuam rau cov khoom uas nyiam, ob qho tib si yuav sib tsoo hnyav, ua rau cov hlau nplaum neo tawg. Tsis tas li ntawd, neodymium lauj kaub hlau nplaum tuaj yeem ua rau tus kheej raug mob los ntawm pinching daim tawv nqaij uas ntog ntawm lawv. Feem ntau, cov khoom no yog magnetized tom qab sib nqus sib nqus.
Ua tsaug rau koj nyeem peb tsab xov xwm, uas peb vam tias tau muab rau koj kom nkag siab zoo dua ntawm khob hlau nplaum. Yog tias koj xav kawm ntxiv txog khob hlau nplaum thiab lwm yam khoom siv hlau nplaum, peb xav kom kojmus saib Honsen Magnetics.
Peb tau koom nrog R&D, tsim khoom, thiab muag khoom ntawm cov hlau nplaum ruaj khov rau ntau tshaj kaum xyoo ua ib qho ntawm cov neeg muag khoom ntawm ntau hom khoom siv hlau nplaum. Yog li ntawd, peb tuaj yeem muab peb cov neeg siv khoom zoo tshaj plaws hauv ntiaj teb tsis tshua muaj hlau nplaum ruaj khov xws li cov hlau nplaum neodymium thiab lwm yam tsis tshua muaj ntiaj teb cov hlau nplaum ruaj khov ntawm cov nqi sib tw heev.
