Kev Sib Piv Kev Ua Haujlwm Ntawm Neodymium Channel Magnets Thiab Lwm Hom Magnet

Tus "Superhero" ntawm Cov Hlau nplaum: Vim li cas Arc NdFeBCov Hlau Nplaum ChannelMuaj zog heev?

Nyob zoo txhua tus! Hnub no, cia peb tham txog cov hlau nplaum - cov khoom me me zoo li qub tab sis zoo nkauj. Koj puas paub? Qhov sib txawv ntawm ntau yam hlau nplaum loj npaum li cov ntawm smartphones thiab xov tooj ntawm tes yooj yim! Tshwj xeeb tshaj yog NdFeB (Neodymium Iron Boron) cov hlau nplaum channel uas tau nrov tsis ntev los no - lawv yog "Iron Man" ntawm lub ntiaj teb hlau nplaum. Yog li lawv zoo kawg nkaus li cas? Dab tsi ua rau lawv sawv tawm ntawm lwm cov hlau nplaum? Tsis txhob txhawj, peb yuav rhuav tshem nws ib kauj ruam zuj zus.

 

1. Ntsib Tsev Neeg Magnet

Ua ntej, cia peb qhia txog "plaub tsev neeg zoo" ntawm cov hlau nplaum:

NdFeB Magnets - Cov "ua tiav siab" ntawm cov hlau nplaum

Tam sim no cov hlau nplaum ruaj khov tshaj plaws hauv ntiaj teb

Ua los ntawm neodymium, hlau, thiab boron

Zoo li "cov neeg ua kom lub cev muaj zog" ntawm cov hlau nplaum - muaj zog heev tab sis rhiab heev me ntsis rau cua sov

Ferrite Magnets - Cov "neeg ua haujlwm"

 

Kev xaiv pheej yig tshaj plaws

Ua los ntawm cov hlau oxide thiab strontium/barium compounds

Kev tiv thaiv corrosion zoo heev tab sis lub zog sib nqus tsis muaj zog

AlNiCo Magnets - Cov "tub rog laus"

Ib qho ntawm cov khoom siv hlau nplaum tas mus li qub tshaj plaws

Kev ruaj khov kub zoo heev

Zoo li cov neeg ncaws pob uas tsis muaj hnub nyoog uas muaj peev xwm tiv thaiv kev demagnetization zoo

SmCo Magnets - Cov "noble elites"

 

Lwm lub hlau nplaum tsis tshua muaj zog uas muaj zog heev

Tiv taus cua sov thiab xeb

Muaj nqi ntau dua li NdFeB, ua rau cov ntawv thov zoo dua

 

2. Lub zog loj ntawm NdFeB Channel Magnets

 

Vim li cas ho hu lawv ua "Iron Man"? Vim lawv muaj cov peev xwm zoo kawg no:

 

Lub Zog Sib Nqus Tsis Sib Xws

Muaj zog dua li cov hlau nplaum ferrite 10 npaug! (Xav txog tus neeg nqa hnyav piv rau tus menyuam kawm ntawv qib pib)

Remanence ncav cuag 1.0-1.4 Tesla (cov hlau nplaum ib txwm tsuas yog ua tiav 0.2-0.4)

Muaj peev xwm tiv thaiv kev demagnetization zoo heev, zoo li tus kab laum uas tsis tuaj yeem rhuav tshem tau

 

Kev Tsim Channel Zoo Kawg Nkaus

Groove tsim tso cai rau kev tswj hwm lub zog magnetic meej, zoo li muab magnetism GPS navigation

Muaj kev ruaj khov dua, tsis tshua muaj kev "tawg"

Yooj yim rau kev teeb tsa, ib yam li kev sib sau ua ke Lego blocks

 

Vaj Ntxwv ntawm Kev Ua Haujlwm Zoo

Txawm hais tias tus nqi ntawm ib chav tsev siab dua li ferrite, nws muab tus nqi qis tshaj plaws rau ib chav tsev sib nqus

Ua tiav qhov muaj zog magnetism nrog qhov me me, txuag ob qho chaw thiab nyiaj txiag

 

3Thaum Twg Yuav Tsum Xaiv Tus "Superhero" Twg?

 

Xaiv NdFeB Channel Magnets thaum:

Qhov chaw tsawg tab sis xav tau lub zog sib nqus muaj zog (piv txwv li, lub mloog pob ntseg wireless, lub tshuab co xov tooj)

Yuav tsum tau tswj hwm lub zog sib nqus kom meej (piv txwv li, cov khoom siv kho mob sib nqus, cov sensors)

Kev txav mus los ntau zaus (piv txwv li, EV motors, drone motors)

Kev tsim qauv sib dua yog qhov tseem ceeb (cov khoom siv aerospace)

 

Xaiv lwm cov hlau nplaum thaum:

Qhov kub thiab txias heev (saum toj no 200 ° C)

Cov xwm txheej corrosive heev (cov khoom siv ntug hiav txwv)

Kev siv nyiaj tsawg rau kev tsim khoom loj

Cov cuab yeej rhiab heev rau kev hloov pauv kub

 

4Cov Lus Qhia rau Kev Siv NdFeB Magnets

 

Muab rau lawv "khaub ncaws":Txheej txheej saum npoo (nickel, zinc, lossis epoxy) rau kev tiv thaiv xeb

Lawv yog cov "glass-hearted":Ua tib zoo saib xyuas thaum lub sijhawm teeb tsa - lawv tawg yooj yim

Kub-rhiab:Qhov kub siab tuaj yeem ua rau "cov leeg poob" mus tas li (demagnetization)

Kev taw qhia tseem ceebYuav tsum tau magnetized raws li kev tsim qauv

Ua tib zoo saib xyuas:Cov teb sib nqus muaj zog tuaj yeem cuam tshuam rau daim npav rho nyiaj, cov moos; khaws cia deb ntawm cov neeg siv lub tshuab pacemaker

 

5Yav Tom Ntej Yuav Muaj Dab Tsi?

 

Cov qauv muaj zog dua:Cov kws tshawb fawb tsim cov qib tshiab muaj zog dua

Ua kom kub dua:Ua rau lawv tsis tshua muaj kev cuam tshuam rau qhov kub thiab txias siab

Cov qauv tsim ntse dua:Siv cov khoos phis tawj los ua kom zoo dua cov qauv channel

Cov kev daws teeb meem ntsuab dua: Txhim kho cov thev naus laus zis rov ua dua tshiab, txo kev siv cov khoom muaj nqis tsawg

Pheej yig dua: Nce kev tsim khoom kom txo cov nqi

 

Cov Kev Xav Kawg

Cov hlau nplaum NdFeB zoo li "cov yeej thoob plaws" ntawm lub ntiaj teb hlau nplaum, qhov kev xaiv thawj zaug rau feem ntau cov ntawv thov thev naus laus zis siab. Tab sis lawv tsis muaj hwj chim tag nrho - ib yam li koj yuav tsis siv lub tsheb kis las los thauj khoom, qhov tseem ceeb yog xaiv cov cuab yeej zoo rau txoj haujlwm.
