Ferrite Igwe Ọdụdọ

Nkọwa dị mkpirikpi:

A na-eme magnetik Ferrite ma ọ bụ seramiiki site na strontium carbonate na ígwè oxide. Ihe ndọta ferrite na-adịgide adịgide nwere ihe ndọta dị mma ma na-efu ọnụ. Ihe ndọta seramiiki na-acha oji ma sie ike ma na-agbaji agbaji.

Mkpado ngwaahịa

A na-ejikarị magnetik Ferrite ma ọ bụ seramiiki eme ihe na ndị na-ekwu okwu, ihe egwuregwu ụmụaka, DC Motors, magnetik lifters, sensọ, microwaves na ulo oru magnetik separators na njikwa usoro, n'ihi ezi iguzogide demagnetization na kasị ala na-eri n'etiti ụdị nile nke na-adịgide adịgide magnets.

Uru

1. Nnukwu na-eguzogide corrosion. Achọghị mkpuchi ọ bụla iji kpuchido magnetik ferrite site na corrosion, mana maka ebumnuche ndị ọzọ, dịka ọmụmaatụ mkpuchi epoxy etinyere iji hụ na magnetik na-adịgide adịgide dị ọcha na enweghị uzuzu.

2. Ọmarịcha thermal arụmọrụ. Ọ bụrụ na ngwaahịa ahụ chọrọ ndọta nke chọrọ ịnabata okpomọkụ dị elu ruo 300 Celsius C, ebe ị na-eji ike ndọta, biko họrọ ịtụle magnetik ferrite na-adịgide adịgide dị ka nhọrọ.

3. Na-eguzogide oke demagnetization.

4. Stable na ọnụ ọnụ ahịa. Ihe ndọta Ferrite zuru oke maka imepụta oke, kpamkpam dịka ihe ndị ahịa chọrọ. Ngwa maka akụrụngwa magnet a dị mfe ịnweta yana adịghị ọnụ.

Ọdịmma

Ike na kenkuwa. Ọ na-eme ka magnetik Ferrite ghara ịdị mma maka ngwa ngwa ngwa n'ịrụ ọrụ, n'ihi nnukwu ihe ize ndụ na ha ga-agbaji ma gbasaa n'okpuru ibu ọrụ.

Otu esi ezere nkwụsịtụ Ferrite na ngwa

1. Ferrite magnet na-emepụta na mgbakọ magnetik.

2. Ferrite magnet na-ejikọta ya na plastik na-agbanwe agbanwe.

Kedu ihe kpatara ịhọrọ Horizon Magnetics dị ka onye na-eweta ihe ndọta Ferrite

N'ezie, anyị abụghị onye nrụpụta magnet Ferrite, mana anyị nwere ihe ọmụma magnetik gbasara ụdị magnetik na-adịgide adịgide gụnyere Ferrite. Ọzọkwa, anyị nwere ike ịnye ebe nkwụsịtụ maka ihe ndọta ụwa na-adịghị ahụkebe, yana mgbakọ magnetik, nke nwere ike ibelata ume ndị ahịa n'imeso ọtụtụ ndị na-eweta ngwaahịa ịzụta ọtụtụ ụdị ngwaahịa magnet n'ọnụ ahịa dị mma.
