Ukusebenza Ukuqhathanisa Phakathi Neodymium Channel Magnets kanye nezinye Izinhlobo Magnet

"Iqhawe" likaZibuthe: Kungani i-Arc NdFeBOmazibuthe BesiteshiUnamandla Kangaka?

Sawubona wonke umuntu! Namuhla, ake sikhulume ngozibuthe - lezi zinto ezincane ezibonakala zivamile kodwa ezithakazelisayo. Uthi bewazi? Umehluko phakathi kozibuthe abahlukahlukene mkhulu njengalowo ophakathi kwama-smartphone namaselula ayisisekelo! Ikakhulukazi omagnethi besiteshi se-NdFeB (Neodymium Iron Boron) abebelokhu bethrenda kamuva nje - empeleni "bayi-Iron Man" yomhlaba kazibuthe. Ngakho zimangalisa kangakanani ngempela? Yini eyenza bahluke kwabanye omazibuthe? Ungakhathazeki, sizokudiliza isinyathelo ngesinyathelo.

 

1. Hlangana noMndeni Wezibuthe

Okokuqala, ake sethule "imindeni emine emikhulu" yomazibuthe:

Omazibuthe be-NdFeB - "Abaphumelele kakhulu" bomazibuthe

Njengamanje omazibuthe abaqine kakhulu emhlabeni

Yakhiwe nge-neodymium, insimbi, ne-boron

"Njengabakhi bomzimba" bomazibuthe - baqine ngendlela emangalisayo kodwa abazwani nokushisa kancane

Ama-Ferrite Magnets - "Amahhashi"

 

Inketho yokonga kakhulu

Yenziwe nge-iron oxide kanye nezinhlanganisela ze-strontium/barium

Ukumelana nokugqwala okuhle kakhulu kodwa amandla kazibuthe abuthaka

I-AlNiCo Magnets - "Omakadebona asebekhulile"

Enye yezinto ezindala kazibuthe unomphela

Ukuzinza kwezinga lokushisa okuvelele

Njengabasubathi abahlale beluhlaza abanamakhono aqinile e-anti-demagnetization

Ama-SmCo Magnets - "Izicukuthwane eziphakeme"

 

Omunye uzibuthe womhlaba ongajwayelekile osebenza kakhulu

Ikwazi ukumelana nokushisa futhi ingagqwali

Ibiza kakhulu kune-NdFeB, ihlinzeka ngezinhlelo zokusebenza ze-premium

 

2. Amandla amakhulu weNdFeB Channel Magnets

 

Kungani ubabiza ngokuthi "Iron Man"? Ngoba banalawa makhono amangalisayo:

 

Amandla Akazibuthe Angenakuqhathaniswa

Amandla aphindwe izikhathi eziyi-10 kunomazibuthe be-ferrite! (Cabanga umuntu ophakamisa izinsimbi uma eqhathaniswa nomfundi wesikole samabanga aphansi)

I-Remanence ifinyelela ku-1.0-1.4 Tesla (omazibuthe abavamile bafinyelela kuphela ku-0.2-0.4)

Ikhono elihle kakhulu le-anti-demagnetization, njengephela elingabhubhi

 

Idizayini Yesiteshi Ehlakaniphile

Idizayini yeGroove ivumela ukulawulwa kwenkundla kazibuthe okunembile, njengokunikeza ukuzulazula kwe-GPS kazibuthe

Isakhiwo esizinzile, asijwayele "ukuphuka"

Kulula ukuyifaka, njengokuhlanganisa amabhulokhi e-Lego

 

Inkosi Yezindleko Zokusebenza

Nakuba intengo yeyunithi iphakeme kune-ferrite, inikeza izindleko eziphansi kakhulu ngeyunithi ngayinye kazibuthe

Izuza uzibuthe oqinile ngosayizi omncane, yonga kokubili isikhala nemali

 

3. Nini ukukhetha Iyiphi "iqhawe"?

 

Khetha Izibuthe Zesiteshi Se-NdFeB lapho:

Isikhala sinomkhawulo kodwa kudingeka uzibuthe oqinile (isb., ama-earbud angenawaya, amamotho wokudlidliza ocingo)

Kudingeka ukulawulwa kwenkundla kazibuthe okunembile (isb, amadivaysi okwelapha kazibuthe, izinzwa)

Ukunyakaza okuvamisile okuhilelekile (isb, ama-EV motors, ama-drone motors)

Idizayini engasindi ihamba phambili (imishini ye-aerospace)

 

Khetha abanye omazibuthe lapho:

Izindawo ezishisa kakhulu (ngaphezu kuka-200°C)

Izimo ezigqwalile kakhulu (impahla yasolwandle)

Isabelomali esiqinile sokukhiqiza ngobuningi

Izinsimbi ezizwela kakhulu ekushintsheni kwezinga lokushisa

 

4. Amathiphu Ukusebenzisa NdFeB Magnets

 

Banikeze "izingubo":I-surface coating (i-nickel, i-zinc, noma i-epoxy) yokuvimbela ukugqwala

"Banenhliziyo yengilazi":Bamba ngokucophelela ngesikhathi sokufakwa - bayaphuka

Izwela ukushisa:Amazinga okushisa aphezulu angabangela "ukulahleka kwemisipha" unomphela (i-demagnetization)

Isiqondiso sibalulekile: Kumele ifakwe uzibuthe ngokuya nge-design orientation

Phatha ngokucophelela:Amandla kazibuthe anamandla angathinta amakhadi esikweletu, amawashi; gcina kude nabasebenzisi benhliziyo

 

5. Liphetheni Ikusasa?

 

Izinguqulo eziqinile:Ososayensi bathuthukisa amamaki amasha anamandla

Okunye ukumelana nokushisa:Ukuwenza angazweli emazingeni okushisa aphezulu

Imiklamo ehlakaniphile:Ukusebenzisa amakhompyutha ukuthuthukisa izakhiwo zamashaneli

Izixazululo eziluhlaza: Ukuthuthukisa ubuchwepheshe bokugaywa kabusha, ukunciphisa ukusetshenziswa komhlaba okungandile

Ithengeka kakhudlwana: Ukukhuphula umkhiqizo ukuze wehlise izindleko

 

Imicabango yokugcina

Ozibuthe besiteshi se-NdFeB bafana "nompetha bawo wonke umhlaba" womhlaba kazibuthe, ukukhetha kokuqala kwezinhlelo zokusebenza eziningi zobuchwepheshe obuphezulu. Kodwa abanamandla onke - njengoba nje ubungeke usebenzise imoto yezemidlalo ukuthutha impahla, ukhiye ukukhetha ithuluzi elifanele lomsebenzi.
