Papiso ea Tshebetso Pakeng tsa Neodymium Channel Magnets le Mefuta e meng ea Magnet

"Superhero" ea Magnets: Hobaneng Arc NdFeBMagnets a kanaleE Matla Hakaale?

Lumelang bohle! Kajeno, ha re bue ka limakete - lintho tsena tse nyane tse bonahalang li tloaelehile empa li khahla. Na u ne u tseba? Phapano lipakeng tsa makenete a fapaneng e kholo joalo ka ea lipakeng tsa li-smartphones le mehala ea cellular! Haholo-holo li-channel tsa NdFeB (Neodymium Iron Boron) tse ntseng li le teng morao tjena - ha e le hantle ke "Iron Man" ea lefats'e la makenete. Joale li hlolla hakae? Ke eng e etsang hore li hlahelle ho limakenete tse ling? Se tšoenyehe, re tla e arola mohato ka mohato.

 

1. Kopana le Lelapa la Magnet

Pele, a re ke re tsebiseng "malapa a mane a maholo" a makenete:

Limanete tsa NdFeB - "Ba atlehileng haholo" ba limatlase

Hajoale ke limakete tse matla ka ho fetisisa lefatšeng

E entsoe ka neodymium, tšepe le boron

Joalo ka "lihahi tsa 'mele" tsa limakete - li matla ka mokhoa o makatsang empa ha li na mocheso hanyane

Ferrite Magnets - The "workhorses"

 

Khetho e ngata ea moruo

E entsoe ka iron oxide le metsoako ea strontium/barium

Ho hanyetsa kutu e ntle haholo empa matla a khoheli a batla a fokola

AlNiCo Magnets - "Bahlabani ba nako e telele"

E 'ngoe ea lisebelisoa tsa khale ka ho fetisisa tsa makenete

E ikhethang mocheso botsitso

Joalo ka baatlelete ba lulang ba le setala ba nang le bokhoni bo matla ba anti-demagnetization

SmCo Magnets - "Bahlomphehi ba phahameng"

 

E 'ngoe e phahameng ea ts'ebetso e sa tloaelehang ea lefats'e makenete

E thibela mocheso ebile e thibela mafome

E theko e phahameng ho feta NdFeB, e sebetsanang le lits'ebetso tsa premium

 

2. The Superpowers ea NdFeB Channel Magnets

 

Ke hobane'ng ha ba li bitsa "Iron Man"? Hobane ba na le bokhoni bona bo makatsang:

 

Matla a Magnetic a sa Bapisoeng

E matla ho feta limakete tsa ferrite makhetlo a 10! (Ak'u nahane ka motho ea phahamisang litšepe ha a bapisoa le moithuti oa sekolo sa mathomo)

Remanence e fihla ho 1.0-1.4 Tesla (limmete tse tloaelehileng li fihlella feela 0.2-0.4)

Bokhoni bo matla ba anti-demagnetization, joalo ka lephele le sa senyeheng

 

Moralo o Bohlale oa Channel

Moralo oa Groove o lumella taolo e nepahetseng ea matla a khoheli, joalo ka ho fana ka magnetism GPS navigation

E tsitsitse haholoanyane, ha e ratehe ho "fractures"

Ho bonolo ho e kenya, joalo ka ho kopanya li-block tsa Lego

 

Morena oa Ts'ebetso ea Litšenyehelo

Le ha theko ea yuniti e phahame ho feta ferrite, e fana ka litšenyehelo tse tlase ho yuniti ka 'ngoe ea makenete

E fihlella magnetism e matla ka boholo bo nyane, e boloka sebaka le chelete

 

3. Nako ea ho Khetha "Superhero" efe?

 

Khetha NdFeB Channel Magnets ha:

Sebaka se na le moeli empa ho hlokahala makenete e matla (mohlala, li-earbud, li-motor tse sisinyehang tsa mohala)

Ho hlokahala taolo e nepahetseng ea matla a khoheli (mohlala, lisebelisoa tsa kalafo ea makenete, lisensara)

Ho tsamaea khafetsa ho ameha (mohlala, li-motor tsa EV, li-motor tsa drone)

Moralo o bobebe ke oa bohlokoa (sesebelisoa sa sefofane)

 

Khetha limakete tse ling ha:

Libaka tsa mocheso o feteletseng (ka holimo ho 200°C)

Maemo a senyang haholo (thepa ea leoatle)

Tekanyetso e thata ea tlhahiso ea bongata

Lisebelisoa tse amehang haholo ha mocheso o fetoha

 

4. Litlhahiso tsa ho Sebelisa Magnets a NdFeB

 

Ba fe "liaparo":Ho roala ka holim'a metsi (nickel, zinki, kapa epoxy) bakeng sa thibelo ea mafome

Li "pelo ea khalase":Tšoara ka hloko nakong ea ho kenya - li brittle

Ha ho na mocheso:Lithempereichara tse phahameng li ka baka "tahlehelo ea mesifa" ka ho sa feleng (demagnetization)

Tataiso e bohlokoa: E tlameha ho ba le makenete ho latela sebopeho sa moralo

Tšoara ka hloko:Matla a matla a makenete a ka ama likarete tsa mokoloto, lioache; hole le basebelisi ba pacemaker

 

5. Bokamoso ke Eng?

 

Liphetolelo tse matla haholoanyane:Bo-rasaense ba hlahisa limaraka tse ncha tse matla haholoanyane

Tse ling tse thibelang mocheso:Ho etsa hore li se utloele mocheso o phahameng

Meetso e bohlale ho feta:Ho sebelisa likhomphutha ho ntlafatsa sebopeho sa likanale

Litharollo tse tala: Ho ntlafatsa theknoloji ea ho tsosolosa, ho fokotsa tšebeliso e sa tloaelehang ea lefatše

Ka theko e tlase: Ho eketsa tlhahiso ho fokotsa litšenyehelo

 

Mehopolo ea ho Qetela

Limanete tsa kanane tsa NdFeB li tšoana le "mampoli a pota-potileng" a lefats'e la makenete, khetho ea pele bakeng sa lits'ebetso tse ngata tsa theknoloji e phahameng. Empa ha ba matla ohle - joalo ka ha o ne o ke ke oa sebelisa koloi ea lipapali ho hula thepa, senotlolo ke ho khetha sesebelisoa se nepahetseng bakeng sa mosebetsi.
