Puas ferrites ua hluav taws xob? Dab tsi ntawm ferrite ua hluav taws xob?

ferrite yog cov khoom sib xyaw ua ke ntawm hlau, oxygen thiab lwm yam hlau, feem ntau siv ferrite yog hom spinel, nickel-zinc hom, kev npaj xws li lub zog siab pob milling txoj kev, co-ua nag txoj kev, thiab lwm yam, nrog siab saturation magnetic induction. lub zog, siab coercivity, tsis tshua muaj magnetic tsis kam, siab resistivity, zoo heev tshuaj stability thiab thermal stability. Ferrites tau siv dav hauv cov ntaub ntawv hluav taws xob, kev sib txuas lus, kev kho mob, cov khoom siv magnetoacoustic, lub zog tshiab, cov khoom siv hluav taws xob hauv tsheb thiab lwm yam, xws li cov hlau nplaum sib nqus, lub taub hau sib nqus, hluav taws xob transformers, motors, cov ntaub ntawv nqus suab, thiab lwm yam.

Peb txhua tus paub tias ferrite tau muab faib ua mos sib nqus thiab tawv kov, peb pom cov lus hais saum toj no hom ferrite belongs rau hard magnetic (sintered ferrite) chav kawm, tsis yog cov khoom sib nqus, cov khoom siv ferrite tsis yog. conductive, yog li thaum ua tsis tuaj yeem xaim txiav rau kev ua haujlwm.

Tau kawg, tsis yog tag nrho cov ferrites tsis yog-conductive, xws li cov hlau nplaum mos uas hais hauv qab no tuaj yeem ua hluav taws xob, tsuas yog qee qhov zoo dua thiab qee qhov tsis muaj zog ntawm permeability.
Yam khoom ferrite twg tuaj yeem ua hluav taws xob?

Cov khoom sib nqus mos yog cov khoom sib nqus nrog cov hlau nplaum permeability thiab tsis tshua muaj hlau nplaum. Lawv lub peev xwm los mloog zoo sib nqus teb nyob rau hauv tej qhov chaw ua rau lawv lug siv nyob rau hauv hluav taws xob motors, transformers, converters thiab lwm yam khoom siv fais fab.

Cov ntaub ntawv sib nqus mos tuaj yeem muab faib ua ob pawg: cov ntawv hlau hluav taws xob zoo tib yam thiab amorphous alloys. Cov ntawv hlau hluav taws xob muaj cov permeability tsawg thiab siab tsis kam, tab sis lawv tau siv dav hauv transformers, motors thiab lwm yam kev lag luam vim lawv pheej yig thiab yooj yim los tsim. Thaum amorphous alloy cov ntaub ntawv muaj ntau dua permeability thiab qis dua, tab sis yog kim dua thiab feem ntau yog siv rau hauv cov khoom siv fais fab, xws li kev kub ceev motors, kev kub ceev transformers, thiab lwm yam.

Hauv cov txheej txheem tsim khoom ntawm cov khoom sib nqus, cov khoom siv txias txias, kub dov thiab cov txheej txheem annealing feem ntau yog siv. Ntawm lawv, annealing yog ib qho ntawm cov txheej txheem tseem ceeb tshaj plaws, uas tuaj yeem tshem tawm cov kev ntxhov siab hauv cov khoom, txhim kho cov hlau nplaum permeability thiab txo cov hlau nplaum tiv thaiv, thiab ua rau cov khoom muag muag.

Cov khoom siv hlau nplaum mos ferrite belongs rau cov khoom siv hluav taws xob, tshwj xeeb siab sib nqus permeability, siab resistivity, feem ntau yog siv nyob rau hauv high zaus, feem ntau yog siv rau kev sib txuas lus hauv hluav taws xob, xws li peb niaj hnub sib cuag nrog computers, TVs, tuaj yeem pom.

Mos sib nqus ferrite feem ntau muaj manganese zinc thiab nickel zinc, ob cov ntaub ntawv manganese zinc ferrite permeability dua nickel zinc ferrite.
