Yuav Ua Li Cas Magnetized Ferrite?
Cov hauv qab no yog cov lus qhia dav dav ntawm cov txheej txheem siv hauv kev tsim khoom lag luam:
Mixing raw khoom
Thawj kauj ruam yuav tsum ua tib zoo sib xyaw cov hlau oxide thiab cov khoom siv carbonate xaiv, nrog rau cov khoom siv ntxiv, los tsim cov hmoov sib tov sib xyaw. Cov proportions ntawm cov ntaub ntawv no tau ua tib zoo tswj kom ua tiav cov khoom sib nqus uas xav tau.
Kev tsim cov Magnet Shape
Cov hmoov sib xyaw ces nias rau hauv cov duab uas xav tau siv hydraulic xovxwm. Cov txheej txheem no tuaj yeem tsim ntau cov duab hlau nplaum, xws li discs, blocks, lossis cov duab kev cai.
Sintering
Cov hlau nplaum tsim yog sintered nyob rau hauv lub qhov cub kub. Thaum lub sij hawm sintering, cov hlau nplaum yog rhuab mus rau qhov kub siab tshaj 1, 000 degrees Celsius (1,832 degrees Fahrenheit) nyob rau hauv ib qho chaw tswj. Cov txheej txheem no fuses cov khoom ua ke thiab hloov cov khoom sib tov rau hauv cov khoom, crystalline qauv.
Txias
Tom qab sintering, cov hlau nplaum yog maj mam txias rau hauv chav tsev kub kom tiv thaiv thermal stresses thiab tawg.
Magnetization

Cov txheej txheem no ua kom cov hlau nplaum sib nqus hauv cov khoom, muab cov hlau nplaum nws cov khoom sib nqus. Cov kauj ruam no feem ntau yog ua los ntawm cov cuab yeej tshwj xeeb uas tuaj yeem tsim cov hlau nplaum uas yuav tsum tau ua.
FAQ
Q: 1.Koj puas tuaj yeem txiav rau hauv ferrite / ceramic hlau nplaum los hloov lawv cov duab?
A: Txawm hais tias nws tsis pom zoo kom txiav lossis hloov ferrite thiab cov hlau nplaum ceramic, nws tuaj yeem ua tau yog tias koj ua tib zoo ua. Txij li cov khoom siv no yog nkig heev thiab tsis yooj yim, txoj hauv kev zoo tshaj plaws los mus txog kev sib cais nws yog kom maj mam thiab ua tib zoo xyaum los ntawm ob sab, yaug tawm lub qhov thaum koj mus.
Q: 2.Yog cov hlau nplaum tas mus li tseem suav tias yog cov hlau nplaum tsis tshua muaj hauv ntiaj teb?
A: Cov hlau nplaum tsis tshua muaj hauv ntiaj teb thiab cov hlau nplaum ruaj khov yog technically tib yam. Ob leeg neodymium hlau nplaum thiab samarium cobalt hlau nplaum yog suav tias yog nyob rau hauv lub ntiaj teb tsis tshua muaj qeb, uas yog ob qho tib si cais raws li kev ruaj ntseg.
Q: 3.Dab tsi yog hom hlau nplaum ruaj khov?
A: Hom muaj zog tshaj plaws ntawm lub ntiaj teb tsis tshua muaj lossis cov hlau nplaum ruaj khov yog cov hlau nplaum neodymium. Txhua yam uas muaj cov ntsiab lus no ua cov khoom tseem ceeb yuav muaj lub zog sib nqus zoo kawg uas tuaj yeem tiv taus yuav luag txhua yam thiab yuav kav ntev li ob peb xyoos.
Q: 4.Cov hlau nplaum twg yog qhov muaj zog tshaj?
A: Neodymium Magnets yog qhov kev xaiv muaj zog tshaj plaws ntawm kev muag khoom rau pej xeem. Muaj zog dua Ferrite Magnets tab sis kim dua. Lawv raug ntsuas los ntawm N28 txog N55 raws li lawv lub zog.
Q: 5.Dab tsi yog N28, N30, N35, N38, N40, N42, N48, N50, N52, N55 cim npe ntawm Neodymium Magnets?
A: Ntawm Neodymium Magnets tsab ntawv N ua raws li tus lej (feem ntau yog los ntawm 28 txog 55) qhia txog qib (magnetic zog) ntawm cov hlau nplaum, uas txuas nrog cov khoom sib nqus flux tso tawm ib chav tsev ntawm ntim. Tus nqi siab dua, cov hlau nplaum muaj zog dua. Rau kev siv, ib qho me me N 45 3 x 2 hli Neodymium disc muaj lub zog nplaum ntawm 0,18 Kg, thaum N48 muaj 0,25 Kg (39% ntau !!!).
Q: 6.Qhov twg Magnets tiv taus qhov kub thiab txias?
A: Ferrite Magnets yog qhov kev daws teeb meem rau kev tiv thaiv tshav kub. Lawv tuaj yeem tiv taus mus txog 180 degree yam tsis muaj teeb meem rau lub zog sib nqus lossis ua haujlwm ntev.
Neodymium Magnets zoo nyob rau hauv chav tsev kub, tab sis lawv cov kev ua tau zoo raug kev txom nyem thaum kub nce. Tshaj li ntawm 100 degree pib, lawv lub zog txo qis kom txog thaum tsis muaj kev txwv tag nrho tom qab 320 degree txwv. Cov alloys tshwj xeeb tuaj yeem siv los tiv thaiv lub caij nplooj zeeg no (txawm tias lawv kim heev thiab tsim los rau kev siv tshwj xeeb). Lub Neodymium Magnet raug kub siab tshaj 80 degree yuav tshwm sim nyob rau hauv ib tug mus tas li poob ntawm kev ua tau zoo, qhov no yuav tshwm sim rau ib tug me me degree rau tus qauv Ferrite Magnets, ib yam nkaus thiab, tab sis tsuas yog thaum kub tshaj 180 degree. Tshwj xeeb Alnico thiab Samarium Magnets tuaj yeem tiv taus qhov kub thiab txias ntawm 525 thiab 650 degree feem.
Q: 7.Yuav ua li cas cov hlau nplaum tiv taus corrosion?
A: Ferrite Magnets yog heev tiv taus corrosion. Lawv tau ua nrog hlau oxide, thiab, vim li ntawd, lawv tsis corrode txawm tias submerged hauv dej. Neodymium Magnets zoo li yuav muaj kev tiv thaiv corrosion. Txhawm rau tiv thaiv cov hlau nplaum tsis zoo, cov txheej tiv thaiv tuaj yeem raug ntxiv, usaully Nickel lossis Copper-Nickel plating, lossis cov yas polymer txheej.
Q: 8.Qhov twg cov hlau nplaum uas pheej yig tshaj?
A: Ferrite Magnets yog qhov kev xaiv pheej yig dua rau cov hlau nplaum lag luam. Neodymium Magnets kim dua (tab sis muaj zog dua), feem ntau yog vim lawv cov ntsiab lus tsis tshua muaj hauv ntiaj teb muaj pes tsawg leeg thiab cov txheej txheem tsim khoom. Rau kev siv, 40x20x10mm Neodymium N35 Nickel coated block tuaj yeem raug nqi 5 euros, thaum Ferrite Magnet ntawm tib qhov loj me nqi tsawg dua 1 euro.
Q: 9.Kuv puas yuav Ferrite lossis Neodymium Magnets?
A: Nws yeej nyob ntawm koj qhov kev xav tau. Neodymium Magnets zoo li ci, du thiab nws yog xim hlau. Lawv muaj zog dua, tab sis kuj kim dua. Tsis tas li ntawd, lawv muaj kev cuam tshuam rau corrosion, oxidation thiab kub kub.
Ferrite Magnets zoo li tsaus nti thiab tsis polished. Lawv yog cov khoom lag luam pheej yig tshaj plaws thiab ua tau zoo rau lawv cov kev ua haujlwm siab kub thiab corrosion.
Q: 10.Dab tsi yog kev siv ferrite nplhaib hlau nplaum?
A: Lawv tau siv los ua cov hlau nplaum ruaj khov rau cov ntawv thov xws li cov hlau nplaum tub yees, cov hais lus nrov, thiab cov tshuab hluav taws xob me me. "Soft" ferrites muaj qis coercivity, yog li lawv yooj yim hloov lawv cov magnetization thiab ua raws li cov conductors ntawm magnetic teb.
Q: 11.Dab tsi yog qhov txawv ntawm ferrite hlau nplaum thiab neodymium?
A: Ferrite hlau nplaum muaj Curie kub dua li cov hlau nplaum Neodymium, yog li lawv tuav lawv cov hlau nplaum zoo dua ntawm qhov kub siab dua. Qhov no muab cov neeg tsim qauv ua haujlwm ntau dua ntawm qhov kub siab dua li cov hlau nplaum Neodymium muab.
Q: 12.Dab tsi yog lub nplhaib ferrite?
A: Ferrite nplhaib cores yog cov hmoov nplej-puab lossis cylindrical-shaped ferrite pieces. Lub hom phiaj ntawm ferrite nplhaib cores yog txhawm rau txo cov suab nrov tam sim no hauv Circuit Court yam tsis muaj av.
Q: 13.Dab tsi yog lub nplhaib hlau nplaum siv rau?
