Kugereranya Imikorere Hagati ya Neodymium Umuyoboro wa Magneti nubundi bwoko bwa Magneti

"Intwari" ya Magneti: Kuki Arc NdFeBUmuyoboro wa MagnetiBirakomeye?

Muraho mwese! Uyu munsi, reka tuvuge kuri magnesi - ibi bisa nkibisanzwe ariko bishimishije ibintu bito. Wari ubizi? Itandukaniro hagati ya magnesi zitandukanye nini nkiyo hagati ya terefone zigendanwa na terefone ngendanwa! By'umwihariko umuyoboro wa NdFeB (Neodymium Iron Boron) umuyoboro wa magneti ugenda ugenda vuba - ni "Iron Iron" w'isi ya rukuruzi. None se biratangaje bite rwose? Niki kibatera kwitandukanya nizindi magneti? Ntugire ikibazo, tuzabigabanya intambwe ku yindi.

 

1. Guhura n'umuryango wa Magnet

Ubwa mbere, reka tumenye "imiryango ine ikomeye" ya magnesi:

NdFeB Magnets - "Abageraho cyane" ya magnesi

Kugeza ubu rukuruzi zikomeye zihoraho kwisi

Igizwe na neodymium, fer, na boron

Kimwe na "abubaka umubiri" ba magnesi - bakomeye bidasanzwe ariko bitumva ubushyuhe buke

Magnite ya Ferrite - "Amafarashi y'akazi"

 

Amahitamo menshi yubukungu

Ikozwe muri oxyde ya fer na strontium / barium

Kurwanya ruswa nziza cyane ariko ugereranije imbaraga za rukuruzi

AlNiCo Magnets - "Abakurambere b'inararibonye"

Kimwe mu bikoresho bya kera bya magneti bihoraho

Ubushyuhe budasanzwe

Kimwe nabakinnyi bahorana icyatsi bafite imbaraga zo kurwanya demagnetisation

Magnets ya SmCo - "Intore zicyubahiro"

 

Ubundi buryo bukomeye cyane budasanzwe isi

Ubushyuhe budashyuha kandi butagira ingese

Igiciro kirenze NdFeB, kugaburira progaramu ya premium

 

2. Ibihugu by'ibihangange bya NdFeB Umuyoboro wa Magneti

 

Kuki babita "Umuntu wicyuma"? Kuberako bafite ubwo bushobozi budasanzwe:

 

Imbaraga za Magnetique ntagereranywa

Inshuro 10 zikomeye kuruta magnite ya ferrite! (Tekereza umutwaro uremereye numunyeshuri wibanze)

Ibisigisigi bigera kuri 1.0-1.4 Tesla (magnesi zisanzwe zigera kuri 0.2-0.4)

Ubushobozi buhebuje bwo kurwanya demagnetisation, nka cockroach idashobora kurimburwa

 

Igishushanyo mbonera

Igishushanyo cya Groove cyemerera magnetiki kugenzura neza, nko gutanga magnetism GPS igenda

Imiterere ihamye, idakunda "kuvunika"

Biroroshye gushiraho, kimwe no guteranya Lego

 

Umwami wibikorwa

Mugihe igiciro cyibiciro kiri hejuru ya ferrite, itanga igiciro gito kuri magnetique

Kugera kuri magnetisme ikomeye hamwe nubunini buto, uzigama umwanya n'amafaranga

 

3. Ni ryari Guhitamo "Intwari"?

 

Hitamo Magnets ya NdFeB iyo:

Umwanya ni muto ariko rukuruzi rukenewe (urugero, gutwi kwamatwi, moteri ya vibrasi ya terefone)

Igenzura rya magnetique isabwa neza (urugero, ibikoresho byo kuvura magnetiki, sensor)

Kugenda kenshi birimo (urugero, moteri ya EV, moteri ya drone)

Igishushanyo cyoroheje nicyambere (ibikoresho byindege)

 

Hitamo izindi magnesi iyo:

Ibidukikije bikabije (hejuru ya 200 ° C)

Ibintu byangirika cyane (ibikoresho byo ku nyanja)

Gukoresha ingengo yimari yumusaruro rusange

Ibikoresho byumva cyane impinduka zubushyuhe

 

4. Inama zo gukoresha Magnets ya NdFeB

 

Bahe "imyenda":Ipfunyika hejuru (nikel, zinc, cyangwa epoxy) kugirango wirinde ingese

Ni "imitima yikirahure":Koresha ubwitonzi mugihe cyo kwishyiriraho - biroroshye

Ubushyuhe bukabije:Ubushyuhe bwo hejuru burashobora gutera "gutakaza imitsi" (demagnetisation)

Icyerekezo: Ugomba gukwega ukurikije icyerekezo

Witondere:Imirima ikomeye ya magnetiki irashobora guhindura amakarita yinguzanyo, amasaha; irinde abakoresha pacemaker

 

5. Igihe kizaza gifashe iki?

 

Impapuro zikomeye:Abahanga batezimbere amanota mashya akomeye

Ibindi birwanya ubushyuhe:Gutuma batumva neza ubushyuhe bwo hejuru

Ibishushanyo mbonera:Gukoresha mudasobwa mugutezimbere imiyoboro

Icyatsi kibisi: Kunoza tekinoroji yo gutunganya, kugabanya imikoreshereze idasanzwe yisi

Birashoboka cyane: Kwagura umusaruro kugirango ugabanye ibiciro

 

Ibitekerezo byanyuma

Umuyoboro wa NdFeB umeze nka "all-round champions" yisi ya magneti, ihitamo ryambere kubikorwa byinshi byikoranabuhanga. Ariko ntabwo ishobora byose - nkuko utari gukoresha imodoka ya siporo mugutwara ibicuruzwa, urufunguzo ni uguhitamo igikoresho cyiza kumurimo.
