Hauv qab no, tib lub tswv yim sib luag coj peb cov khoom messaging - muab pebLub niam hlaudaws los ntawm cov lus teb rau cov lus nug uas koj cov neeg tuaj yeem tshawb nrhiav.

Dab tsi yog ferrite hlau nplaum - txoj ntsiab cai, cov khoom thiab siv rooj plaub

Nws yog dab tsi thiab nws ua li cas?

A Ferrite hlau nplaum(Kuj tau ua "Ceramic hlau nplaum" lossis "nyuaj ferrite") yog cov hlau nplaum ua los ntawm cov hlau oxide (Fe₂o₃) ua ke nrog cov tshuaj khib nyiab hlau (feem ntau barium lossis strontium).

Cov txheej txheem dav dav cuam tshuam:

• Nws sib xyaw hlau oxide + barium / strontium carbonate hmoov

• Nias / moulding rau hauv cov duab

• Sintering ntawm qhov kub thiab txias nyob rau hauv kev tswj cov cua

• Lub niam hlauizing hauv Kev Sib Nqus Sib Nqus

Vim tias ferrite yog hluav taws xob insulating, nws muaj qis eddy-tam sim no poob.

Key lub cev thiab cov khoom sib nqus

Ntawm no yog qhov sib piv ntawm Ferrite Magnet Li Khoom:

Siv cov xwm txheej & Qhov zoo / Qhov Tsis Zoo

Qhov Zoo:

• Raug nqi-ua tau zoo: cov ntaub ntawv raw muaj ntau thiab pheej yig

• Zoo tshaj plaws corrosion tsis kam thiab ib puag ncig ruaj khov

• Kev Ua Kom Zoo Siab Kub Kub

• Hluav taws xob rwb thaiv tsev - tsawg kawg eddy tam sim no poob

Txwv:

• Qis dua qub zog zog (flux ntom ntom)

• Bulkier lossis hnyav dua rau kev sib nqus kev sib sib zog nqus

• Nyiam kom haum rau miniaturized high-zog cov ntawv thov

Cov ntawv thov raug muaj xws li:

• Nrov nrov, microphones

• Cov motors (tsawg rau ib nrab-qib)

• Sib nqus sib cais (qhov chaw siab-ib-chav tsis tau)

• Sensors, Sib Sau Sib Nqus Hauv Cov Khoom Siv Hluav Taws Xob

Hauv cov ntsiab lus, cov hlau nplaum muaj kev ntseeg siab, pheej yig thaum muaj zog sib nqus tsis yog qhov tseem ceeb tshaj plaws yog qhov tseem ceeb.

Dab tsi yog sintered ndFeB hlau nplaum - thev naus laus zis, kev ua tau zoo thiab rooj sib piv

Dab tsi yog sintered ndfeb, thiab nws tsim li cas?

A Sintered ndfeb lub niam hlauyog cov kev ua tau zoo tsawg-ntiaj teb tas mus li hlau nplaum ua los ntawm hmoov metallurgy.

Cov kauj ruam tsim khoom lag luam:

1. Alloy yaj thiab cntsis

2. Pulverization / Hydrogen-chinespitation / Kev Sib Tsoo Zoo rau Micro Hmoov

3. Sibrial thiab nias rau hauv kev sib nqus teb

4. Sintering (Densification) hauv lub tshuab nqus tsev lossis hauv roj

5. Kev Kho Cua Sov / annealing los ua kom rov zoo microstructure

6. Machining (txiav, sib tsoo, puab ntawm ncej)

7. Kev Kho Mob Nto / Txheej (NI, Ni-Cu-Ni, Epoxy, thiab lwm yam)

Vim tias sintered ndfeb yog nkig, cov ntawv foos yog feem ntau ua tiav rau hauv geometries kawg-sintering.

Kev ua tau zoo thiab txwv

Sintered NdFeB hlau nplaum yog nyob ntawm cov hlau nplaum muaj zog tshaj plaws muaj. Qee qhov kev kawm paub ua haujlwm:

• Cov khoom lag luam hluav taws xob (bh_max):33 mus rau 51 mgoe (≈ 265 txog 408 kj / m³)

• Nco ntsoov (B_R):~ 1.0 - 1.5 t

• Kev sib koom tes (H_CJ):mus txog ~ 2000 ka / m (txawv ntawm qib)

• Ntawj ntom:~ 7.3 - 7.7 G /M³

• Kev Ua Haujlwm Kub:Cov qib raug nce mus txog ~ 80-200 ° C; Cov qhab nia tshwj xeeb tuaj yeem txhawb siab dua tab sis nrog kev rau txim

Vim tias cov ntsiab lus hlau siab yog cov ua rau oxidation,Cov txheej txheem plaub lossis tiv thaiv txheej txheemyog qhov tseem ceeb (piv txwv li noteb. Nickel, Nicuni, epoxy) los tiv thaiv corrosion thiab kev tsis pom zoo.

Kev sib piv: SININTEDED NDFEB VS Ferrite vs BRTED NDFEB

Txhawm rau kom pom qhov twg sintered ndFeb haum, ntawm no yog lub rooj sib piv ntawm peb hom magnetat:

Los ntawm kev sib piv,Sintered ndfebyog xaiv thaum siab sib nqus flux nyob rau hauv qhov chaw sib xyaw yog qhov tseem ceeb - E.G. Hauv cov motors, actuags, sensors, khoom siv kho mob.Ferriteyog qhov zoo tshaj plaws thaum tus nqi, kev ruaj khov, thiab ib puag ncig resilience tseem ceeb tshaj plaws.Bonded ndfeb(Txawm hais tias tsis yog peb tsom rau ntawm no) yog qhov nruab nrab: zoo dua cov txheej txheem yooj yim, tus nqi qis, tab sis tsis muaj zog sib nqus khoom.
