Abangane abajwayelene nozibuthe bayazi ukuthi ozibuthe be-iron boron baqashelwa emakethe yezinto kazibuthe njengezimpahla zikazibuthe ezisebenza kahle kakhulu futhi ezingabizi kakhulu. Zenzelwe ukusetshenziswa ezinhlobonhlobo zeimboni yobuchwepheshe obuphezulus, okuhlanganisa ezokuvikela kazwelonke nezempi, ubuchwepheshe be-elekthronikhi, nezisetshenziswa zezokwelapha, izinjini, izinto zikagesi, izinto zikagesi, neminye imikhakha. Lapho zisetshenziswa kakhulu, kuba lula ukubona izinkinga. Phakathi kwalokhu, ukukhishwa kazibuthe kazibuthe we-iron-boron anamandla ezilungiselelweni zokushisa okuphezulu kuthole isithakazelo esikhulu.Okokuqala nokubaluleke kakhulu, kufanele siqonde ukuthi kungani i-NeFeB ikhipha uzibuthe ezindaweni zokushisa okuphezulu.
Isakhiwo somzimba se-Ne iron boron sinquma ukuthi kungani ikhipha uzibuthe ezindaweni zokushisa okuphezulu. Ngokuvamile, uzibuthe angakwazi ukukhiqiza indawo kazibuthe ngenxa yokuthi ama-electron athuthwa into ngokwayo azungeza ama-athomu aye ohlangothini oluthile, okuholela kumandla kazibuthe anomthelela osheshayo ezindabeni ezizungezile ezixhunyiwe. Nokho, izimo ezithile zokushisa kufanele kuhlangatshezwane nazo ukuze ama-electron azungeze ama-athomu endaweni ethile. Ukubekezelela izinga lokushisa kuyahlukahluka phakathi kwezinto ezisebenza kazibuthe. Lapho izinga lokushisa likhuphuka kakhulu, ama-electron ayaduka emzileni wawo wokuqala, okuholela esiphithiphithini. Lokhu Kuleli qophelo, indawo kazibuthe yasendaweni izophazamiseka, okuzoholela ekuthenidemagnetization.Izinga lokushisa lokuyeka uzibuthe le-boron yensimbi yensimbi ngokuvamile linqunywa ukwakheka kwayo okukhethekile, amandla kazibuthe, nomlando wokwelapha ukushisa. Izinga lokushisa lokuyeka uzibuthe le-boron yensimbi yegolide ngokuvamile liphakathi kuka-150 no-300 degrees Celsius (302 kanye no-572 degrees Fahrenheit). Kuleli banga lokushisa, izici ze-ferromagnetic ziwohloka kancane kancane zize zilahleke ngokuphelele.
Izisombululo ezimbalwa eziyimpumelelo ze-NeFeB uzibuthe we-high-temperature demagnetization:
Okokuqala nokubaluleke kakhulu, ungashisi kakhulu umkhiqizo uzibuthe we-NeFeB. Qaphela izinga lokushisa layo elibucayi. Izinga lokushisa elibalulekile likazibuthe we-NeFeB livamise ukuzungeze ama-degree Celsius angu-80 (176 degrees Fahrenheit). Lungisa indawo yayo yokusebenza ngokushesha ngangokunokwenzeka. I-Demagnetization ingancishiswa ngokukhuphula izinga lokushisa.
Okwesibili, ukuqala ngobuchwepheshe ukuthuthukisa ukusebenza kwemikhiqizo esebenzisa omazibuthe be-hairpin ukuze ibe nesakhiwo esifudumele futhi ingathinteki kalula emithonyeni yemvelo.
Okwesithathu, ngomkhiqizo ofanayo wamandla kazibuthe, ungakhethaizinto zokuphoqelela eziphezulu. Uma lokho kwehluleka, unganikela kuphela inani elincane lomkhiqizo wamandla kazibuthe ukuze uzuze ukuphoqelelwa okuphezulu.
I-PS: Impahla ngayinye inezici ezihlukile, ngakho-ke khetha okufaneleyo futhi ukonga, futhi uyicabangele ngokucophelela lapho uklama, ngaphandle kwalokho izobangela ukulahlekelwa!
Qagela ukuthi unentshisekelo: Unganciphisa kanjani noma uvimbele ukukhishwa kazibuthe okushisayo kanye ne-oxidation ye-iron boron, okuholela Ekuncipheni kokuphoqelela?
Impendulo: Lokhu kuyinkinga nge-thermal demagnetization. Kunzima ngempela ukulawula. Naka ukulawulwa kwezinga lokushisa, isikhathi kanye ne-vacuum degree ngesikhathi se-demagnetization.
Ngabe uzibuthe we-iron-boron uzodlidliza ngamuphi imvamisa bese uphelelwa uzibuthe?
I-magnetism kazibuthe unomphela ngeke ikhishwe uzibuthe ngenxa yokudlidliza kwemvamisa, futhi injini enesivinini esikhulu ngeke ikhishwe uzibuthe ngisho nalapho isivinini sifinyelela ku-60,000 rpm.
Okuqukethwe kazibuthe okungenhla kuhlanganiswe futhi kwabelwa i-Hangzhou Magnet Power Technology Co., Ltd. Uma uneminye imibuzo kazibuthe, sicela ukhululekethintana nesevisi yamakhasimende eku-inthanethi!
