Iimagnethi zeFerrite (Ceramic).
Iimagnethi zeFerrite, eziqhele ukubizwa ngokuba ziimagnethi zeceramic, azinyangeki ekumdleni kwaye zinokusetyenziswa emanzini ngaphandle kokufumana umhlwa.Ukunyanzeliswa kwabo okuphezulu kunye neendleko eziphantsi ngokwentelekiso zibenza balunge kakhulu ukusetyenziswa kwiimotor kunye neenjini zobushushu obuphezulu, nangona zingomelelanga njengaye.Iimagnethi zomhlaba ezinqabileyo zeNeodymium(NdFeB).
Iimagnethi zeFerrite zisebenza kakuhle kwizicelo ezingabizi kakhulu.
Ukongeza kokugquma ngombane, iimagnethi ze-ferrite zithintela imisinga ye-eddy ukuba ihambe ngaphakathi kubo.
Iimagnethi zeFerrite zisebenza kakuhle kumaqondo obushushu aphezulu kodwa azifanelekanga kangako kwiindawo ezibanda kakhulu.
Ceramic, Feroba, kunyeIimagnethi zeFerrite ezinzimangamanye amagama eFerrite Magnets.Ziphakathi kwezixhobo zeiimagnethi ezisisigxinaezisetyenziswa kakhulu kwihlabathi jikelele.Iimagnethi zeFerrite zizixhobo ezingabizi kakhulu zemagnethi ezilungele ukwenziwa kwezinto ezinkulu.Ngenxa yobuchule bawo obuphezulu bokugquma umbane, zaziwa njengeeseramics.
Iimpawu kunye neempawu zeFerrite Magnets
Iimagnethi zeFerrite zigqwesile kwiimeko ezifumileyo, ezimanzi, okanye zaselwandle kuba ziyakwazi ukumelana nomhlwa.Ngenxa yokuba intsimbi sele ikwimeko ezinzileyo ene-oxidized kwisakhiwo sayo, ayikwazi ukuqhubeka ne-oxidize ("rust") emanzini.Iimagnethi zeCeramic Ferrite zihlelwa zibe ziindidi ezimbini: iStrontium Ferrite (SrO.6Fe2O3) imagnethi kunye neBarium Ferrite (BaO.6Fe2O3) imagnethi.Ngenxa yeempawu zabo eziphezulu zemagneti, iimagnethi zeStrontium Ferrite zezona ziveliswa rhoqo.
Iimagnethi zeFerrite (imagnethi zeCeramic) zinombala "wepensile" owahlukileyo (oko kukuthi umbala omnyama ongwevu).Zineempawu zemagneti ze-ferrimagnetic (indawo entle yamagnetic kunye namandla kodwa, ubukhulu bobungakanani, abunamandla njengeNdFeB okanye iSmCo).Zisetyenziswa kakhulu kwiinjini, kwiijenereyitha, kwizandisi-lizwi, nakwiziyilo zaselwandle, nangona zinokufumaneka kulo naliphi na ishishini.umz. ezeZithutho, iiSensors, oomatshini, iAerospace, uMkhosi, iZibhengezo, ezoMbane/i-Electronic, ezeMfundo, iNdlu yoYilo, kunye ne-R&D ngamanye amashishini amelweyo.Iimagnethi zeFerrite zinokuqashwa kumaqondo obushushu ukuya kuma +250 degrees Celsius (kwiimeko ezithile, ukuya kuthi ga kuma +300 degrees celcius).Iimagnethi zeFerrite ngoku zinikezelwa kumabakala angama-27.I-C5 (i-Feroba2, i-Fer2, i-Y30, kunye ne-HF26/18) kunye ne-C8 ngamabakala amabini aqhelekileyo asetyenziswayo namhlanje (eyaziwa ngokuba yi-Feroba3, Fer3, kunye ne-Y30H-1).I-C 5 / Y30 yiMagnet yeFerrite eqhelekileyo esetyenziswa kwizicelo ezifana neemagnethi ezingaphezulu.I-C8 / Y30H-1 lukhetho oluphezulu kwizicelo ezifana nezandisi-lizwi kwaye, kwezinye iimeko, ii-motor (i-C8 ine-Br efanayo ne-C5 kodwa ine-Hc ephezulu kunye ne-Hci).Iimagnethi zeFerrite zinokwenziwa ngeendlela ezahlukeneyo kunye nobukhulu.Iinkqubo zokusila ziyafuneka kumatshini wobukhulu njengoko imathiriyeli yeFerrite yokugquma ngombane ingenzi ukhukuliseko lwentlantsi yocingo.Iimilo eziphambili zinjaloiibhloko, iidiski, imisesane, arcs, kwayeiintonga.
Pukuqaliswa
Iiferrites zenziwe ngokufudumeza kumaqondo obushushu aphezulu umxube wecandelo leeoxides zesinyithi, njengoko kubonisiwe kule nxaki ifanelekileyo:
ZnFe2O4 = Fe2O3 + ZnO
Kwezinye iimeko, umxube we-precursor ococekileyo ocolekileyo ucinezelwe kwi-mold.Ezi zinyithi zibonelelwa ngokuqhelekileyo njenge-carbonates, i-BaCO3 okanye i-SrCO3, ye-barium kunye ne-strontium ferrites.Ezi carbonates zibalwa ngexesha lenkqubo yokufudumala:
MO + CO2 MCO3
Ukulandela eli nqanaba, iioksidi ezimbini ziyaxubana zenze i-ferrite.I-Sintering yenziwa kwi-oxide yesiphumo
Ukwenziwa Kwemveliso
Ukucofa kunye nokuSintering
Ukucofa kunye nokuntywila yinkqubo yokucinezela umgubo ocolekileyo kakhulu weferrite kwidayiti emva koko ucofe umazibuthe.Yile ndlela zonke iimagnethi ezishinyeneyo zeFerrite zenziwa ngayo.Iimagnethi zeFerrite zinokucinezelwa nokuba zimanzi okanye zomile.Ukucinezela okumanzi kuvelisa iimpawu ezinkulu zemagnethi kodwa ukunyamezela komzimba okubi.Ngokubanzi, umgubo webakala 1 okanye 5 uyomile, ngelixa umgubo webakala 8 nangaphezulu ufumile.I-Sintering yinkqubo yokufudumeza imathiriyeli kumaqondo obushushu aphezulu ukuze kudityaniswe umgubo ocoliweyo kunye, kubangele into eyomeleleyo.Iimagnethi ezenziwe kusetyenziswa obu buchwepheshe zifuna ukwenziwa komatshini wokugqibela;ngaphandle koko, ukugqitywa komphezulu kunye nokunyamezela akwamkelekanga.Abanye abavelisi bakhupha umgubo omanzi odaka endaweni yokuwucinezela baze bawufake.Kwiifom zecandelo le-arc, i-arc cross-section ngamanye amaxesha ikhutshwe ngobude obukhulu, i-sintered, kwaye inqunywe ubude.
Isitofu sokubumba
Umgubo weFerrite udityaniswe kwikhompawundi kunye nesitofu esibunjwe ngendlela efanayo neplastiki.Izixhobo zobu buchule bokuvelisa kudla ngokubiza imali eninzi.Nangona kunjalo, izinto ezenziwe ngale ndlela zinokuba neefom ezinzima kakhulu kunye nokunyamezela okungqongqo.Iimpawu zesitofu esibunjiweyo se-ferrite zingaphantsi okanye ziyafana nezo zebakala 1 ferrite.

Usetyenziso olufuna amaqondo obushushu aphezulu.
Iimagnethi zembizakunye neenkqubo zokubambelela ngexabiso eliphantsi
Iimagnethi ze-Overband zezandisi-lizwi
Ngokomzekelo, inkampani yayisebenzisaImagnethi ye-NdFeB Neodymiumukubambelela kwindawo eshushu ethambileyo yentsimbi;iimagnethi zazingasebenzi kakuhle, kwaye iindleko zaziyingxaki.Sanikezelaiimagnethi zembiza yeferrite&ezinye iindibano zemagnethi, ezingazange zivelise amandla aneleyo okutsala ngokuthe ngqo nje kuphela kodwa ezazikwazi ukumelana namaqondo obushushu aphakamileyo, azizange zonakaliswe kukukhuselwa yimagnethi yembiza yaye zazingabizi kakhulu yaye kulula ukuzigcina.
Iimagnethi zeferrite ezinzimainokubunjwa ngokwezoqoqosho ngamakhonkco, amacandelo, iibhloko, iidiski, iintonga, njl.
Isitofu Inayiloni kunye nomgubo weferritezidityanisiwe ukwenza iimagnethi ze-ferrite.Ukwandisa i-magnetic orientation, yenziwe kwintsimi yamagnetic.
EMIFerrite Core, MnZn Ferrite Core, Magnetic Powder Core, Iron Powder Core, SMD Ferrite Core, Amorphous Core
Iimagnethi zembiza yeferriteZiquka umazibuthe weceramic esongelwe kwiqokobhe lentsimbi kwaye zenzelwe ukuba zibambe ngqo kumphezulu wentsimbi.
Hard ferrite Ukubamba iimagnethi(iindibano zemagnetic) zeemilo ezahlukeneyo kunye nobukhulu, njengeSikwere, iDiskhi, kunye neRing Holding Magnets, ziyafuneka kuluhlu olubanzi lwezicelo kumashishini amaninzi kunye nobunjineli.
