Ukuqhathaniswa Kokusebenza Phakathi Kwama-Neodymium Channel Magnets Nezinye Izinhlobo Zama-Magnet

"Iqhawe Elinamandla" Lama-Magnets: Kungani i-Arc NdFeBOmazibuthe BesiteshiUnamandla Kangaka?

Sawubona nonke! Namuhla, ake sixoxe ngamamagnethi - lezi zinto ezincane ezibonakala zivamile kodwa ezithakazelisayo. Ubuwazi? Umehluko phakathi kwamamagnethi ahlukahlukene mkhulu njengalawo aphakathi kwama-smartphone namaselula ayisisekelo! Ikakhulukazi amamagnethi esiteshi se-NdFeB (Neodymium Iron Boron) abelokhu ethandwa muva nje - empeleni ayi-"Iron Man" yomhlaba wamamagnethi. Ngakho-ke amangalisa kangakanani ngempela? Yini ewenza ahluke kwabanye omagnethi? Ungakhathazeki, sizowahlukanisa kancane kancane.

 

1. Hlangana Nomndeni Wama-Magnet

Okokuqala, ake sethule "imindeni emine emikhulu" yamagnethi:

Ama-NdFeB Magnets - "Amandla aphezulu" ama-magnets

Njengamanje omaginethi abaqinile kunabo bonke emhlabeni

Yakhiwe nge-neodymium, insimbi, ne-boron

Njengabakhi bomzimba bamagnethi - banamandla kakhulu kodwa bazwela ukushisa kancane

Ama-Ferrite Magnets - "Amahhashi asebenzayo"

 

Inketho engabizi kakhulu

Kwenziwe ngamakhemikhali e-iron oxide kanye ne-strontium/barium

Ukumelana okuhle kakhulu nokugqwala kodwa amandla kazibuthe abuthakathaka kakhulu

Ama-AlNiCo Magnets - "Amaqhawe anolwazi"

Enye yezinto ezindala kakhulu ezisebenzisa umazibuthe

Ukuqina kwezinga lokushisa okuvelele

Njengabadlali abasafufusa abanamakhono aqinile okulwa nokukhishwa kwamandla kagesi

Ama-SmCo Magnets - "Izicukuthwane ezihloniphekile"

 

Enye imagnethi yomhlaba ongavamile esebenza kahle kakhulu

Ayimelani nokushisa futhi ayigqwali

Ibiza kakhulu kune-NdFeB, ihambisana nezinhlelo zokusebenza ze-premium

 

2. Amandla Aphezulu KaMagnets Esiteshi Se-NdFeB

 

Kungani bebizwa ngokuthi "Iron Man"? Ngoba banamakhono amangalisayo:

 

Amandla Angalinganiswanga KaMazibuthe

Amandla aphindwe kayishumi kunamagnethi e-ferrite! (Cabanga ngomuntu ophakamisa izinsimbi uma kuqhathaniswa nomfundi wesikole samabanga aphansi)

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

Ikhono elihle kakhulu lokulwa nokukhishwa kwamandla kagesi, njenge-cockroach engenakubhujiswa

 

Umklamo Wesiteshi Ohlakaniphile

Umklamo we-groove uvumela ukulawulwa okunembile kwensimu yamagnetic, njengokunikeza ukuzulazula kwe-GPS kwe-magnetism

Ukuqina kwesakhiwo, ukungathandi "ukuphuka"

Kulula ukuyifaka, njengokuhlanganisa amabhlogo eLego

 

Ukusebenza Kwenkosi Yezindleko

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

Ifinyelela amandla okubutha aqinile ngosayizi omncane, isindisa isikhala nemali

 

3Ukukhetha Nini "Iqhawe"?

 

Khetha oMagnethi Besiteshi se-NdFeB uma:

Isikhala sincane kodwa kudingeka amandla adonsela phansi aqinile (isb., ama-earbud angenantambo, ama-motor okudlidliza kwefoni)

Kudingeka ukulawulwa okunembile kwensimu yamagnetic (isb., amadivayisi okwelapha amagnetic, izinzwa)

Ukunyakaza okuvamile okubandakanyekayo (isb., ama-EV motors, ama-drone motors)

Umklamo olula uyinto eza kuqala (imishini yezindiza)

 

Khetha amanye amamagnethi uma:

Izindawo ezishisa kakhulu (ngaphezu kuka-200°C)

Izimo ezigqwala kakhulu (imishini eseceleni kolwandle)

Isabelomali esincane sokukhiqiza ngobuningi

Izinsimbi zizwela kakhulu ekushintsheni kwezinga lokushisa

 

4Amathiphu Okusebenzisa Ama-NdFeB Magnets

 

Banike "izingubo":Ukugqoka okuphezulu (i-nickel, i-zinc, noma i-epoxy) ukuvimbela ukugqwala

"Banenhliziyo yengilazi":Phatha ngokucophelela ngesikhathi sokufakwa - ziyaphuka

Iyazwela ukushisa:Ukushisa okuphezulu kungabangela "ukulahlekelwa yimisipha" unomphela (ukususwa kwemagnetization)

Isiqondiso sibalulekile: Kumelwe kufakwe ugesi ngokuya ngomklamo oqondiswe kuwo

Phatha ngokucophelela:Amandla kazibuthe anamandla angathinta amakhadi esikweletu, amawashi; gcina kude nabasebenzisi be-pacemaker

 

5Liphetheni Ikusasa?

 

Izinguqulo eziqinile:Ososayensi bathuthukisa amamaki amasha anamandla kakhulu

Imelana nokushisa kakhulu:Ukubenza bangazweli kakhulu emazingeni okushisa aphezulu

Imiklamo ehlakaniphile:Ukusebenzisa amakhompyutha ukuthuthukisa izakhiwo zesiteshi

Izixazululo eziluhlazaUkuthuthukisa ubuchwepheshe bokusebenzisa kabusha, ukunciphisa ukusetshenziswa komhlaba ongavamile

Okungabizi kakhulu: Ukwandisa umkhiqizo ukuze wehlise izindleko

 

Imicabango Yokugcina

Omaginethi besiteshi se-NdFeB bafana "namaqhawe aphelele" omhlaba wamaginethi, ukukhetha kokuqala kwezinhlelo zokusebenza eziningi zobuchwepheshe obuphezulu. Kodwa abanamandla onke - njengoba nje ungeke usebenzise imoto yezemidlalo ukuthutha izimpahla, isihluthulelo ukukhetha ithuluzi elifanele lomsebenzi.
