tuaj yeem ferrite ua hluav taws xob

Ferrite yog cov khoom siv dav siv, thiab nws cov khoom tshwj xeeb thiab cov nqi siv tau zoo heev los ntawm tib neeg. Ferrite yog dav siv hauv electronics, kev sib txuas lus, motors, electronics computers thiab lwm yam kev lag luam. Yog li, ferrite puas tuaj yeem ua hluav taws xob? Dab tsi ntawm ferrite tuaj yeem ua hluav taws xob? Cia peb saib luv luv hauv qab no.

Ua ntej tshaj plaws, ferrite yog cov khoom siv hluav taws xob, uas feem ntau muab faib ua ob hom: tawv ferrite thiab mos ferrite. Hard ferrite muaj cov khoom sib nqus siab thiab siab saturation sib nqus induction siv, thiab tuaj yeem siv los ua cov hlau nplaum ruaj khov thiab electromagnets. Mos ferrite muaj cov khoom sib nqus tsis tshua muaj thiab tsis tshua muaj kev sib nqus sib nqus induction, thiab feem ntau yog siv los ua cov khoom siv hluav taws xob xws li electromagnet cores thiab high-frequency transformers.

Thib ob, hauv cov khoom siv hluav taws xob, ferrite muaj hluav taws xob zoo. Ntawm cov ferrites nyuaj, Co-Z thiab Ni-Z ferrites feem ntau siv cov khoom siv hluav taws xob. Lub resistivity ntawm Co-Z ferrite yog qhov me me, thiab nws tuaj yeem siv los ua cov khoom siv ntau zaus xws li cov hlau nplaum thiab cov hlau nplaum electromagnet cores, thiab qhov taw qhia lub suab nrov tsawg. Ni-Z ferrite muaj ib tug loj resistivity thiab yuav siv tau raws li ib tug tsawg zaus ntaus ntawv xws li ib tug sib nqus core thiab ib tug electromagnet core.

Ntawm cov ferrites mos, zinc ferrite yog cov khoom siv hluav taws xob siab. Zinc ferrite yog ib qho yooj yim los npaj, tsis tshua muaj nqi, muaj siab resistivity thiab zoo hluav taws xob conductivity, yog li nws yog dav siv nyob rau hauv kev tsim cov khoom siv hluav taws xob.

Feem ntau, ferrite yog ib qho ntawm cov khoom siv hluav taws xob zoo thiab siv dav hauv kev npaj cov khoom siv hluav taws xob. Ntawm ntau hom ferrites, ferrite cov ntaub ntawv uas muaj Co, Ni thiab Zn muaj cov khoom siv hluav taws xob zoo, thiab cov cuab yeej tsim muaj cov khoom siv hluav taws xob ruaj khov thiab ua haujlwm zoo. Txawm li cas los xij, peb yuav tsum nco ntsoov tias cov hluav taws xob conductivity ntawm ferrite yog ze rau cov khoom xws li cov khoom siv hluav taws xob thiab cov txheej txheem npaj, yog li nws yuav tsum tau ua tib zoo xaiv thiab tswj hauv daim ntawv thov.
