Neodymium hlau nplaum yog qhov zoo tshaj plaws irreversible hlau nplaum uas muag, nyob qhov twg hauv lub ntiaj teb no.tiv thaiv demagnetisation thaum sib piv rau ferrite, alnico thiab txawm samarium-cobalt hlau nplaum.
✧ Neodymium hlau nplaum VS cov hlau nplaum ferrite
Ferrite hlau nplaum yog cov hlau nplaum uas tsis yog xim hlau raws li triiron tetroxide (tsawg loj piv ntawm hlau oxide rau ferrous oxide).Lub ntsiab qhov tsis zoo ntawm cov hlau nplaum no yog tias lawv tsis tuaj yeem forged ntawm lub siab nyiam.
Neodymium hlau nplaum tsis tsuas yog muaj lub zog sib nqus zoo heev, tab sis kuj muaj cov khoom siv kho tshuab zoo vim yog cov fusion ntawm cov hlau, thiab tuaj yeem ua tau yooj yim ua ntau yam duab kom haum rau ntau yam kev xav tau.Qhov tsis zoo yog tias cov hlau monomers hauv cov hlau nplaum neodymium yog ib qho yooj yim rau xeb thiab deteriorate, yog li qhov saum npoo kuj feem ntau plated nrog npib tsib xee, chromium, zinc, tin, thiab lwm yam los tiv thaiv xeb.
✧ Kev sib xyaw ntawm neodymium hlau nplaum
Neodymium hlau nplaum yog ua los ntawm neodymium, hlau thiab boron fused ua ke, feem ntau yog sau li Nd2Fe14B.Vim yog qhov ruaj khov muaj pes tsawg leeg thiab muaj peev xwm tsim cov tetragonal muaju, cov hlau nplaum neodymium tuaj yeem txiav txim siab los ntawm cov tshuaj lom neeg pom.1982, Makoto Sagawa ntawm Sumitomo Tshwj Xeeb Hlau tsim neodymium hlau nplaum thawj zaug.Txij thaum ntawd los, Nd-Fe-B hlau nplaum tau maj mam tshem tawm ntawm cov hlau nplaum ferrite.
✧ Cov hlau nplaum neodymium ua li cas?
KAUJ RUAM 1- Ua ntej tshaj plaws, tag nrho cov ntsiab lus los ua kom cov hlau nplaum xaiv zoo yog muab tso rau hauv lub tshuab nqus tsev vacuum induction rauv, rhuab zoo li thawed los tsim cov khoom siv hlau.Qhov kev sib xyaw no yog tom qab txias kom tsim cov ingots ua ntej yuav hauv av rau hauv cov nplej me me hauv lub dav hlau zeb.
KAUJ RUAM 2- Cov hmoov zoo super yog ces nias rau hauv pwm thiab tib lub sij hawm sib nqus zog siv rau pwm.Magnetism yog los ntawm ib lub coil ntawm cable uas ua raws li cov hlau nplaum thaum muaj hluav taws xob tam sim no dhau los ntawm nws.Thaum lub moj khaum ntawm cov hlau nplaum sib phim cov lus qhia ntawm cov hlau nplaum, qhov no yog hu ua anisotropic hlau nplaum.
KAUJ RUAM 3- Qhov no tsis yog qhov kawg ntawm cov txheej txheem, hloov pauv, lub sijhawm no cov khoom siv hlau nplaum yog demagnetized thiab yuav raug magnetised tom qab thaum ua li ntawd.Cov kauj ruam tom ntej yog rau cov khoom yuav tsum tau rhuab mus, xyaum mus txog melting point nyob rau hauv ib tug txheej txheem hu ua Cov nram qab no kev txiav txim yog rau cov khoom yuav tsum tau rhuab, yuav luag txog thaum melting point nyob rau hauv ib tug txheej txheem hu ua sintering uas ua rau cov hmoov hlau nplaum fuse ua ke.Cov txheej txheem no tshwm sim hauv qhov chaw tsis muaj oxygen, tsis muaj zog.
KAUJ RUAM 4- Zoo nyob ntawd, cov khoom siv cua sov tau txias sai heev uas siv txoj kev hu ua quenching.Txoj kev ua kom txias sai sai no txo qhov chaw ntawm cov hlau nplaum tsis zoo thiab tseem ua rau muaj kev ua tau zoo.
KAUJ RUAM 5- Vim tias cov hlau nplaum neodymium nyuaj heev, ua rau lawv muaj kev cuam tshuam rau kev puas tsuaj thiab kev puas tsuaj, lawv yuav tsum tau coated, ntxuav, qhuav tawm, thiab kuj plated.Muaj ntau ntau hom kev ua tiav uas tau siv los ntawm cov hlau nplaum neodymium, ib qho ntawm feem ntau yog npib tsib xee-tooj liab-nickel mix tab sis lawv tuaj yeem coated rau lwm cov hlau thiab roj hmab lossis PTFE.
KAUJ RUAM 6- sai li sai tau plated, cov khoom tiav yog re-magnetised los ntawm muab tso rau hauv ib lub kauj, uas, thaum hluav taws xob tam sim no mus los ntawm nws generates ib tug hlau nplaum peb zaug ntau zog tshaj qhov tsim nyog toughness ntawm hlau nplaum.Qhov no yog ib txoj hauv kev zoo uas yog tias cov hlau nplaum tsis khaws cia rau hauv qhov chaw nws tuaj yeem cuam tshuam los ntawm lub kauj-zoo li lub mos txwv.
AH MAGNET yog IATF16949, ISO9001, ISO14001 thiab ISO45001 chaw tsim tshuaj paus ntawm txhua yam kev ua haujlwm siab neodymium hlau nplaum thiab sib nqus sib nqus nrog ntau tshaj 30 xyoo ntawm kev paub hauv kev ua haujlwm.Yog tias koj txaus siab rau neodymium hlau nplaum, thov koj xav tiv tauj peb!
