Txawm hais tias ntau tus neeg siv khoom feem ntau yuav tsum tau yuav cov hlau nplaum tsis tshua muaj lub ntiaj teb NdFeB, lawv paub me ntsis txog lawv. Tus editor feem ntau ntsib cov neeg siv khoom zoo li no. Ib tus neeg siv khoom hais tias: "Kuv xav tau cov hlau nplaum muaj zog, cov hlau nplaum kub", tab sis nug seb nws yog dab tsi. Nws tsis paub tias cov hlau nplaum loj npaum li cas. Niaj hnub no, cia peb qhia luv luv txog kev ua tau zoo ntawm lub ntiaj teb tsis tshua muaj NdFeB cov hlau nplaum muaj zog.
Lub ntiaj teb tsis tshua muaj NdFeB cov hlau nplaum muaj zog xa mus rau cov hlau nplaum muaj zog, cov npe kev tshaj lij: cov hlau nplaum tsis tshua muaj lub ntiaj teb muaj zog hlau nplaum, NdFeB, thiab lwm yam. Cov hlau nplaum no feem ntau muaj kev ua haujlwm siab thiab muaj zog sib nqus, thiab siv dav hauv cov khoom ua si, ntim thawv, teeb, khoom siv tes ua, hais lus. , machinery, khoom kho mob, khoom siv hluav taws xob, cov cuab yeej kho vajtse thiab lwm yam khoom siv.
Feem ntau siv yog N33, N35, N38 thiab lwm yam peb yam khoom ntawm lub ntiaj teb tsis tshua muaj NdFeB cov hlau nplaum muaj zog, uas yog, cov ntaub ntawv zoo tib yam. Feem ntau, qhov kev ua tau zoo dua, cov ntaub ntawv zoo dua, thiab tus nqi siab dua. Yog li, feem ntau hais lus, yog tias cov kev xav tau tsis siab heev, kev siv cov hlau nplaum nrog cov khoom peb yuav luag tib yam.
N40 thiab saum toj no yog qhov ua tau zoo tsis tshua muaj lub ntiaj teb neodymium hlau boron muaj zog hlau nplaum. Qhov kev ua tau zoo no feem ntau yog siv hauv xov tooj ntawm tes, cov cuab yeej precision, aerospace, thiab kev tshawb fawb txog kev tshawb fawb. Nws tuaj yeem muab faib ua cuaj yam khoom: N40, N42, N45, N48, N50, thiab N52. Cuaj lub zog yog tag nrho nyob rau hauv tsawg dua los yog sib npaug rau 80 degree . Thaum qhov kub no dhau lawm, lawv yuav demagnetize.
Yog li yog tias cov neeg siv khoom xav txog qhov kub thiab txias thiab xav tau kev ua haujlwm siab, nws raug nquahu kom siv cov khoom hauv qab no:
①Nws xaus nrog M, piv txwv li: N50M, qhov kub tsis kam yog feem ntau Tsawg dua lossis sib npaug li 100 degree;
② xaus nrog H, piv txwv li: N48H, qhov kub tsis kam yog feem ntau Tsawg dua lossis sib npaug li 120 degree;
③ xaus nrog SH, piv txwv li: N45SH, qhov kub tsis kam yog feem ntau Tsawg dua lossis sib npaug li 150 degree;
④ xaus nrog UH, piv txwv li: N35UH, qhov kub tsis kam yog feem ntau Tsawg dua lossis sib npaug li 180 degree;
⑤ xaus nrog EH, piv txwv li: N35EH, qhov kub tsis kam yog feem ntau Tsawg dua lossis sib npaug li 200 degree;
