Cov Hlau Npib Neodymium Yog Dab Tsi?

Neodymium Magnets: Cov Cheebtsam Me Me, Kev Cuam Tshuam Loj Tiag Tiag

Los ntawm kev xam pom txog kev tsim kho, kev hloov pauv ntawm cov hlau nplaum tub yees mus rau cov hom neodymium yog qhov dhia hauv lub peev xwm. Lawv cov qauv ib txwm muaj - lub disc yooj yim lossis thaiv - tsis lees paub qhov kev ua tau zoo ntawm cov hlau nplaum zoo kawg nkaus. Qhov kev sib txawv ntawm lawv qhov tsos me me thiab lawv lub zog ntawm lub zog tseem ceeb tseem ua rau muaj kev cov nyom loj hauv kev tsim qauv thiab daim ntawv thov. Ntawm no ntawm Fullzen, peb tau pom cov khoom muaj zog no hloov pauv cov khoom thoob plaws ntau qhov chaw. Tsis ntev los no, ib qho kev nce qib yog ntes qhov chaw: scov neeg ua haujlwm qhovhlau nplaum eodymiumQhov ua rau qhov kev tsim kho tshiab no muaj tswv yim heev yog nws qhov yooj yim dag ntxias. Nws yog hom kev daws teeb meem zoo nkauj thiab yooj yim uas pom tseeb tam sim ntawd.

Ntau Tshaj Li Cov Hlau Nplaum Muaj Zog Dua

Yog tias koj xav txog lub hlau nplaum uas zoo dua qub, koj yuav tsis nkag siab tag nrho. Cov hlau nplaum neodymium (feem ntau hu ua NdFeB lossis "neo" hlau nplaum) yog ib qho kev dhia tseem ceeb hauv kev siv tshuab hlau nplaum. Tsim los ntawm cov hlau sib xyaw ua ke uas tsis tshua muaj neeg paub, lawv ua tiav qhov zoo li tsis zoo li yuav tshwm sim: tsim kom muaj zog hlau nplaum zoo kawg nkaus los ntawm cov pob khoom uas me me thiab sib dua. Qhov tshwj xeeb no tau dhau los ua lub cav tom qab kev ua kom me me ntawm cov khoom siv hauv ntau daim ntawv thov. Txawm hais tias peb tab tom tham txog kev cog hniav kho mob uas cawm txoj sia lossis lub mloog pob ntseg uas txo suab nrov uas koj vam khom thaum mus ncig, cov thev naus laus zis no tau hloov kho peb cov peev xwm thev naus laus zis. Tshem tawm cov hlau nplaum neodymium, thiab niaj hnub no qhov chaw thev naus laus zis yuav tsis paub.

Nkag Siab Txog Lub Hwj Chim Ua Tau

Peb tuaj yeem tham txog kev tshawb fawb txog hlau nplaum tsis kawg, tab sis kev ua tau zoo hauv ntiaj teb tiag tiag hais tau ntau yam. Piv txwv li, peb lub hlau nplaum N52 qib disc: nws hnyav kwv yees li ib lub nyiaj npib tab sis tuaj yeem nqa tau tag nrho 2 kilograms. Qhov no tsis yog kev kwv yees hauv chav kuaj xwb - peb txheeb xyuas cov txiaj ntsig no los ntawm kev sim tsis tu ncua. Lub peev xwm no txhais tau tias cov kws tsim qauv feem ntau tuaj yeem hloov cov hlau nplaum ceramic uas siv qhov chaw ntau nrog cov neodymium lwm txoj hauv kev uas siv chav tsawg dua.

Txawm li cas los xij, txhua tus neeg tsim qauv yuav tsum paub txog qhov tseeb tseem ceeb no: lub zog zoo li no xav tau kev tuav zoo. Kuv tus kheej tau pom cov hlau nplaum neodymium me me dhia hla lub rooj ua haujlwm thiab tawg thaum raug. Kuv tau pom lawv ntswj tawv nqaij hnyav txaus kom tawg nws. Cov hlau nplaum loj dua xav tau kev ceev faj ntxiv, ua rau muaj kev pheej hmoo tiag tiag. Tsis muaj chaw rau kev sib tham ntawm no - kev tuav kom zoo tsis yog tsuas yog pom zoo xwb, nws tseem ceeb heev.

Cov Txheej Txheem Tsim Khoom: Ob Txoj Kev

Txhua lub hlau nplaum neodymium muaj cov khoom xyaw yooj yim zoo ib yam: neodymium, hlau, thiab boron. Qhov txaus nyiam yog nyob rau hauv seb cov tuam txhab tsim khoom hloov cov khoom sib xyaw no mus ua cov hlau nplaum ua haujlwm li cas:

Cov Hlau Npib Sintered Neodymium
Thaum koj daim ntawv thov xav tau kev ua haujlwm zoo tshaj plaws ntawm lub zog sib nqus, cov hlau nplaum sintered yog qhov kev daws teeb meem. Cov txheej txheem tsim khoom pib nrog kev yaj cov khoom siv raw hauv lub tshuab nqus tsev, tom qab ntawd los ntawm kev sib tsoo lawv ua hmoov zoo heev. Cov hmoov no tau raug nias rau hauv cov pwm hauv qab lub zog sib nqus, tom qab ntawd dhau los ntawm sintering. Yog tias koj tsis paub txog lo lus, xav txog kev sintering ib qho txheej txheem tswj cua sov uas khi cov khoom me me yam tsis tau yaj tag nrho. Cov zis yog ib qho khoom siv ntom ntom, tawv uas dhau los ntawm kev ua haujlwm raug, tau txais kev tiv thaiv txheej txheem (feem ntau yog nickel), thiab thaum kawg tau txais magnetized. Txoj hauv kev no ua rau cov hlau nplaum muaj zog tshaj plaws muaj niaj hnub no.

Cov Hlau Noob Sib Txuas Neodymium
Qee zaum lub zog sib nqus tsis yog koj qhov kev txhawj xeeb nkaus xwb. Qhov no yog qhov uas cov hlau nplaum sib txuas tuaj rau hauv. Cov txheej txheem no suav nrog kev sib xyaw cov hmoov sib nqus nrog cov polymer binder xws li nylon lossis epoxy, uas tom qab ntawd raug tsim los ntawm kev siv compression lossis txhaj tshuaj molding. Cov txheej txheem no muab cov chaw tsim khoom tsis muaj kev txwv kev ywj pheej tsim qauv. Qhov kev sib haum xeeb? Qee qhov kev ua tau zoo sib nqus. Qhov zoo? Koj tuaj yeem tsim cov duab sib xyaw, meej uas yuav tsis yooj yim lossis tsis yooj yim sua los ntawm kev sintering.

Kev Tshawb Fawb Txog Xov
