Ferrite (Ceramic) Magnets
Ozibuthe be-Ferrite, abavame ukubizwa ngokuthi ngozibuthe be-ceramic, abakwazi ukugqwala futhi bangasetshenziswa emanzini ngaphandle kokugqwala.Ukuphoqwa kwazo okuphezulu kanye nezindleko eziphansi uma kuqhathaniswa kuzenza zibe zinhle kakhulu ekusebenziseni izinjini kanye namamotho ashisa kakhulu, naphezu kweqiniso lokuthi azinamandla njengawo.Izibuthe Ze-Neodymium Zomhlaba Ezingavamile(NdFeB).
Ozibuthe beFerrite basebenza kahle ezinhlelweni ezingabizi kakhulu.
Ukwengeza i-insulating kagesi, omazibuthe be-ferrite bavimbela ama-eddy currents ukuthi angagelezi ngaphakathi kwawo.
Ozibuthe be-Ferrite basebenza kahle emazingeni okushisa aphezulu kodwa abafaneleki kangako ezindaweni ezibandayo kakhulu.
Ceramic, Feroba, futhiHard Ferrite Magnetskukhona amanye amagama Ferrite Magnets.Ziphakathi kwezinto zokwakhaozibuthe unomphelaezisetshenziswa kakhulu emhlabeni jikelele.Ozibuthe beFerrite bayizinto zikazibuthe ezingabizi ezilungele imigijimo emikhulu yokukhiqiza.Ngenxa yamakhono azo aphakeme okuvikela ugesi, aziwa ngokuthi ama-ceramics.
Izici & Izimpawu Ferrite Magnets
Ozibuthe be-Ferrite bahle kakhulu ezimweni eziswakeme, ezimanzi, noma zasolwandle ngoba abakwazi ukugqwala.Ngenxa yokuthi insimbi isivele isesimweni esine-oxidized ezinzile esakhiweni sayo, ayikwazi ukuqhubeka ne-oxidize ("rust") emanzini.Ozibuthe be-Ceramic Ferrite bahlukaniswa ngezinhlobo ezimbili: omagnethi be-Strontium Ferrite (SrO.6Fe2O3) kanye nozibuthe be-Barium Ferrite (BaO.6Fe2O3).Ngenxa yezici zabo eziphakeme kazibuthe, omagnethi be-Strontium Ferrite yibo abakhiqizwa njalo.
Ozibuthe be-Ferrite (Ozibuthe beCeramic) banombala "wepensela womthofu" ohlukile (okungumbala ompunga omnyama).Zinezakhiwo kazibuthe ze-ferrimagnetic (insimu enhle kazibuthe namandla kodwa, usayizi wosayizi, awunamandla njenge-NdFeB noma i-SmCo).Asetshenziswa kakhulu kumamotho, amajeneretha, izikhulisa-zwi, nemiklamo yasolwandle, nakuba engase atholakale cishe kunoma iyiphi imboni.isb Ezezimoto, Izinzwa, Imishini, I-Aerospace, Amasosha, Ukukhangisa, Ezogesi/Ama-elekthronikhi, Ezemfundo, Indlu Yokuklama, kanye ne-R&D ngezinye zezimboni ezimelwe.Ozibuthe beFerrite bangase basetshenziswe emazingeni okushisa afinyelela ku-+250 degrees Celsius (kwezinye izimo, afinyelele ku-+300 degrees Celsius).Ama-Ferrite Magnets manje anikezwa ngamamaki angama-27.I-C5 (Feroba2, Fer2, Y30, ne-HF26/18) kanye ne-C8 amamaki amabili asetshenziswa kakhulu namuhla (aziwa nangokuthi i-Feroba3, Fer3, ne-Y30H-1).I-C 5 / Y30 iyizibuthe ezivamile zeFerrite ezisetshenziswa ezinhlelweni ezifana nozibuthe be-overband.I-C8 / Y30H-1 iyisinqumo esingcono kakhulu sezinhlelo zokusebenza ezifana nezipikha futhi, kwezinye izimo, amamotho (i-C8 ine-Br efanayo ne-C5 kodwa ine-Hc ne-Hci ephakeme).Ozibuthe be-Ferrite bangenziwa ngezindlela ezihlukahlukene nobukhulu.Izinqubo zokugaya ziyadingeka ekwenziweni komshini kasayizi njengoba impahla yeFerrite efaka ugesi ingavumeli ukuguguleka kwenhlansi yocingo.Izimo eziyinhloko zinjaloamabhlogo, amadiski, izindandatho, ama-arcs, futhiizinduku.
Pukwethulwa
Ama-Ferrite akhiwa ngokushisisa emazingeni okushisa aphezulu ingxube yengxenye yensimbi ye-oxides, njengoba kubonisiwe kulesi sibalo esihle:
ZnFe2O4 = Fe2O3 + ZnO
Kwezinye izimo, ingxube yesandulela eyimpuphu ecolekile icindezelwa esikhunjeni.Lezi zinsimbi zivame ukuhlinzekwa njengama-carbonates, i-BaCO3 noma i-SrCO3, ye-barium ne-strontium ferrites.Lawa ma-carbonates abalwa ngesikhathi sokushisisa:
I-MO + CO2 MCO3
Ukulandela lesi sigaba, ama-oxide amabili ayahlangana enze i-ferrite.I-Sintering yenziwa kumphumela we-oxide
Ukukhiqiza Ukucubungula
Ukucindezela & Sintering
Ukucindezela nokucwilisa kuyinqubo yokucindezela impushana ye-ferrite ecwebe kakhulu edayishini bese ucwilisa uzibuthe ocindezelwe.Yile ndlela wonke ama-Ferrite aminyene ngokuphelele asebenza ngayo.Ozibuthe be-Ferrite bangase bacindezelwe noma bamanzi noma bomile.Ukucindezela okumanzi kukhiqiza izici ezinkulu kazibuthe kodwa ukubekezelelana okubi kakhulu ngokomzimba.Ngokuvamile, izimpushana zebanga loku-1 noma lesi-5 zomile, kuyilapho izimpushana zebanga lesi-8 nangaphezulu zinomswakama.I-Sintering inqubo yokushisisa okokusebenza kumazinga okushisa aphezulu ukuze kuhlanganiswe impushana echotshoziwe ndawonye, okuholela ekubeni kube into eqinile.Izibuthe ezenziwe kusetshenziswa lobu buchwepheshe ngokuvamile zidinga ukwenziwa kwemishini kokugcina;ngaphandle kwalokho, ukuqedwa kwendawo nokubekezelelana akwamukeleki.Abanye abakhiqizi bakhipha udaka lwempushana olumanzi kunokuba balicindezele bese belucwilisa.Kumafomu engxenye ye-arc, ingxenye ye-arc cross-section ngezinye izikhathi ikhishwa ngobude obukhulu, i-sintered, bese isikwa ibe ubude.
Ukubunjwa komjovo
Impushana ye-Ferrite ihlanganiswa ibe yinhlanganisela futhi umjovo ubunjwe ngendlela efanayo nepulasitiki.Amathuluzi ale ndlela yokukhiqiza ngokuvamile kubiza kakhulu.Kodwa-ke, izinto ezidalwe yile ndlela zingaba namafomu ayinkimbinkimbi kakhulu kanye nokubekezelelana okuqinile.Izimfanelo ze-ferrite ebunjiwe yomjovo ziphansi noma zifana nalezo ze-ferrite yebanga loku-1.
Izicelo Okujwayelekile for Ferrite (Ceramic) Magnets
Amajeneretha nezinjini
Amamitha
Izicelo olwandle
Izinhlelo zokusebenza ezidinga amazinga okushisa aphezulu.
Ozibuthe basebhodwenikanye nezinhlelo zokubopha ngenani eliphansi
Ozibuthe be-Overband bezipikha
Ngokwesibonelo, inkampani yayisebenzisaOzibuthe be-NdFeB Neodymiumukubopha phezu kwensimbi ethambile eshisayo;omazibuthe babengasebenzi kahle, futhi izindleko zaziyinkinga.Sinikeleomazibuthe ebhodweni le-ferrite&ezinye izilinganiso kazibuthe, ezingagcini nje ngokukhiqiza amandla anele okudonsa aqondile kodwa ezazikwazi ukumelana namazinga okushisa aphakeme, azizange zilinyazwe ukuvikelwa umklamo kazibuthe webhodwe futhi zazingabizi futhi kulula ukuzinakekela.
Ozibuthe be-ferrite abaqinileingabunjwa ngokwezomnotho ngezindandatho, izingxenye, amabhlogo, amadiski, izinduku, njll.
Umjovo Inayiloni ne-ferrite powderzihlanganiswe ukuze zenze omazibuthe be-ferrite.Ukwandisa i-orientation kazibuthe, kwakhiwa endaweni kazibuthe.
I-EMII-Ferrite Core, MnZn Ferrite Core, Magnetic Powder Core, Iron Powder Core, SMD Ferrite Core, Amorphous Core
Ozibuthe basebhodweni likaFerriteakhiwe uzibuthe we-ceramic esongwe ngaphakathi kwegobolondo lensimbi futhi ahloselwe ukubamba ngqo endaweni yensimbi.
I-ferrite eqinile Ephethe Magnets(ama-magnetic assemblies) anomumo nosayizi abahlukahlukene, njengesikwele, i-Disc, kanye Nozibuthe Ababambe Indandatho, kuyadingeka ezinhlobonhlobo zezinhlelo zokusebenza ezimbonini eziningi nezobunjiniyela.
