Tuam Tshoj SmCo Magnets Chaw tsim tshuaj paus: Innovations nyob rau hauv High-Temperature Magnet Technology

Lus piav qhia luv luv:

Samarium-cobalt (SmCo) hlau nplaum yog siv nyob rau hauv ntau yam kev siv uas kub stability thiab muaj zog magnetic teb yuav tsum tau.Lawv feem ntau siv hauv kev lag luam xws li aerospace, automotive, cov cuab yeej kho mob, thiab cov cuab yeej tsim khoom.Qee qhov kev siv tshwj xeeb muaj xws li hluav taws xob motors, sensors, magnetic bearings, thiab magnetic couplings.Vim lawv cov coercivity siab thiab tsis kam mus demagnetization, SmCo hlau nplaum yog tshwj xeeb tshaj yog haum rau hnyav kev khiav hauj lwm tej yam kev mob.Samarium-cobalt (SmCo) hlau nplaum paub txog lawv lub zog tshwj xeeb, feem ntau yog cov muaj zog ruaj khov hlau nplaum muaj.Lawv feem ntau muaj cov khoom siv hluav taws xob siab, uas ua rau lawv muaj zog magnetic teb.Qhov no ua rau lawv zoo rau cov ntawv thov uas yuav tsum muaj lub zog sib nqus.Txawm li cas los xij, lub zog tshwj xeeb ntawm SmCo hlau nplaum tuaj yeem sib txawv raws li nws qib thiab cov txheej txheem tsim khoom.Yog tias koj muaj ib daim ntawv thov tshwj xeeb hauv siab, nws yuav muaj txiaj ntsig los sab laj nrog peb kom paub meej ntxiv txog lub zog ntawm SmCo hlau nplaum muaj rau koj cov kev xav tau.

Product Detail

Khoom cim npe

Dhau li ntawd, SmCo hlau nplaum muaj lwm yam nta:
Txhim khu kev ua tau zoo: SmCo hlau nplaum tsis tshua muaj zog rau demagnetization ua rau lawv txhim khu kev qha hauv ntau qhov chaw.
Corrosion thiab oxidation tsis kam: Vim muaj cov ntsiab lus hlau tsawg hauv cov khoom sib xyaw, SmCo hlau nplaum muaj kev tiv thaiv zoo heev.Tsis zoo li NdFeB, SmCo hlau nplaum tsis xav tau electroplating.
Kev ruaj ntseg kub: SmCo tuaj yeem ua kom nws lub zog sib nqus ntawm qhov kub thiab txias (249-300 ℃) thiab kub tsis tshua muaj (-232 ℃).
Brittle cov ntaub ntawv: Thaum nyob rau hauv sintering, cov khoom tej zaum yuav nkig, vim nws yog nkig thiab yooj yim rau tawg, kev ua muaj kev txwv, uas cov tsoos txheej txheem yog tsis ua hauj lwm.Txawm li cas los xij, nws tuaj yeem ua tau hauv av, tab sis tsuas yog siv ntau npaum li cas ntawm cov coolant.Tias yog vim li cas lub coolant tuaj yeem txo qhov kev pheej hmoo ntawm hluav taws kub los ntawm thermal tawg thiab oxidized sib tsoo plua plav.

Daim ntawv thov:
1. High-end PM motors.General PM motors feem ntau siv cov hlau nplaum ferrite lossis NdFeB hlau nplaum.Tab sis nyob rau hauv qhov chaw uas qhov kub tshaj 200 ℃ los yog lub torque torque loj, tsuas yog SmCo PM motors muaj peev xwm.
2. Cov khoom siv hluav taws xob hauv cov tshuab ua suab nrov nrov.
3. Cov cuab yeej siv tau zoo heev.Ntau cov cuab yeej siv hauv aerospace, aviation, kev kho mob thiab lwm yam kev lag luam yuav tsum siv cov hlau nplaum ruaj khov SmCo kom ntseeg tau tias muaj kev ntseeg siab thiab zoo meej.
4. Nyob rau hauv lub radar thiab kev sib txuas lus tseem ceeb heev, muaj coob tus neeg mus ncig yoj raj, magnetrons, chasing tubes, chasing yoj raj, gyrotrons thiab lwm yam hluav taws xob nqus tsev vacuum li, thiab SmCo hlau nplaum ua electron beams raws lub tsiv raws txoj kev.
5. SmCo magnetic extractors nyob rau hauv qhov tob tob hauv qab 3000 meters, thiab SmCo magnetic tsav (tswj) nyob rau hauv kub kub ib puag ncig ntawm 200 ℃.
6. Sib nqus nqus taub hau, sib nqus sib nqus, sib nqus bearing, NMR, thiab lwm yam.
