Parizvino, zvakajairika zvechigarire magineti magineti ferrite,NdFeb magineti, SmCo magineti, Alnico magineti, rubber magineti uye zvichingodaro.Izvi zviri nyore kutenga, nekuita kwakajairwa (kwete hazvo ISO zviyero) kusarudza kubva.Imwe neimwe yemagineti ari pamusoro ane maitiro ayo uye akasiyana masimidhi ekushandisa, iwo akaunzwa muchidimbu ndeaya anotevera.
Neodymium magineti
NdFeb igineti rinoshandiswa zvakanyanya uye richikura nekukurumidza.
Neodymium magineti inoshandiswa zvakanyanya kubva pakugadzirwa kusvika ikozvino, asiwo anopfuura makore makumi maviri.Nekuda kweiyo yakakwirira magineti zvivakwa uye nyore kugadzirisa, uye mutengo hauna kunyanya kukwira, saka iyo nzvimbo yekushandisa iri kuwedzera nekukurumidza.Parizvino, iyo yekutengesa NdFeb, yayo magineti simba chigadzirwa inogona kusvika 50MGOe, uye iri gumi nguva dzeferrite.
NdFeb zvakare iri poda metallurgy chigadzirwa uye inogadziriswa nenzira yakafanana kune samarium cobalt magineti.
Parizvino, tembiricha yakakwira yeNdFeb yakatenderedza 180 degrees Celsius.Pakushandisa kwakakasharara, zvinowanzokurudzirwa kuti isapfuure 140 madhigirii Celsius.
NdFeb yakasvibiswa zviri nyore.Naizvozvo, mazhinji ezvigadzirwa zvakapedzwa zvinofanirwa kuve electroplated kana kuvharwa.Kugadziriswa kwepamusoro kwepamusoro kunosanganisira nickel plating (nickel-copper nickel), zinc plating, aluminium plating, electrophoresis, etc. Kana ukashanda munzvimbo yakavharwa, unogonawo kushandisa phosphating.
Nekuda kweiyo yakakwira magineti eNdFeb, muzviitiko zvakawanda, inoshandiswa kutsiva mamwe magineti zvinhu kudzikisa huwandu hwezvigadzirwa.Kana ukashandisa ferrite magnets, ukuru hwefoni yemazuva ano, ndinotya kwete pasi pehafu yezvidhinha.
Iwo magineti maviri ari pamusoro ane zvirinani kugadzirisa kuita.Naizvozvo, kushivirira kwedimensional kwechigadzirwa kuri nani kupfuura iyo ferrite.Kune zvigadzirwa zvakajairika, kushivirira kunogona kuva (+/-) 0.05mm.
Samarium Cobalt magineti
Samarium cobalt magineti, izvo zvinongedzo zvikuru ndeye samarium uye cobalt.Nekuti mutengo wezvinhu unodhura, samarium cobalt magineti ndeimwe yemhando dzinodhura.
Iyo magineti simba chigadzirwa chesamarium cobalt magineti anogona parizvino kusvika 30MGOe kana kutopfuura.Mukuwedzera, samarium cobalt magineti ndeyekumanikidza zvakanyanya uye yakakwirira-yekushisa inodzivirira, uye inogona kuiswa kune tembiricha inosvika 350 degrees Celsius.Zvekuti hazvigone kudzoserwa mune akawanda maapplication
Samarium cobalt magineti ndeyeupfu metallurgy zvigadzirwa.Vagadziri vezvese zvinoenderana nehukuru uye chimiro chechigadzirwa chakapedzwa chinodiwa, vanopiswa kuita sikweya isina chinhu, vobva vashandisa blade yedhaimondi kucheka muhukuru hwechigadzirwa chapera.Nekuti samarium cobalt inofambisa magetsi, inogona kuchekwa zvine mutsetse.Tichifunga, samarium cobalt inogona kuchekwa kuita chimiro chinogona kutemwa mutsara, kana magnetization uye saizi yakakura isingatariswe.
Samarium cobalt magineti ane yakanakisa corrosion kuramba uye kazhinji haidi anti-corrosion plating kana kupeta.Mukuwedzera, samarium cobalt magineti ane brittle, zvakaoma kugadzira zvigadzirwa mumadiki madiki kana madziro matete.
Alnico magineti
Alnico magineti ine kukanda uye sintering maviri akasiyana maitiro nzira.Zvigadzirwa zvemumba zvakanyanya kukanda Alnico.Iyo magineti simba chigadzirwa cheAlnico magineti inogona kusvika ku9MGOe, uye ine hombe ficha ndeyekuti ndeyekupisa tembiricha kuramba, tembiricha yekushanda inogona kusvika 550 degrees Celsius.Nekudaro, Alnico magineti iri nyore kwazvo kuita demagnetize mune inverted magnetic field.Kana ukasaidzira mapango maviri eAlnico magineti munzira imwechete (mbiri maN kana maviri maS) pamwe chete, munda weimwe yemagineti unodzoserwa kana kudzoserwa kumashure.Naizvozvo, haina kukodzera kushanda mune inverted magnetic field (yakadai semota).
Alnico ine kuomarara kwakanyanya uye inogona kugadzikwa uye kuchekwa waya, asi nemutengo wepamusoro.General kupihwa kwezvigadzirwa zvakapedzwa, kune marudzi maviri ekukuya zvakanaka kana kusakuya.
Ferrite magineti / Ceramic magineti
Ferrite imhando yeisinametallic magineti zvinhu, inozivikanwawo semagineti ceramics.Isu tinotora redhiyo yakajairwa yakaparadzana, uye nyanga magineti mairi iri ferrite.
Iyo magnetic properties yeferrite haisi yakakwirira, ikozvino magineti simba chigadzirwa (imwe yemiganhu yekuyera kushanda kwemagineti) inogona kungoita 4MGOe zvishoma zvishoma.Izvo zvinhu zvine mukana mukuru wekuve wakachipa.Parizvino, ichiri kushandiswa zvakanyanya munzvimbo dzakawanda
Ferrite ndeye ceramic.Naizvozvo, kuita kwemuchina kwakafanana neye ceramics.Ferrite magineti ari kuumba mold, sintering kunze.Kana zvichidikanwa kugadzirisa, kungokuya nyore chete kunogona kuitwa.
Nekuda kwekuoma kwekugadzira michina, saka mazhinji echimiro cheferrite chiri nyore, uye ukuru kushivirira kwakakura.Square shape zvigadzirwa zvakanaka, zvinogona kugaya.Denderedzwa, kazhinji kukuya ndege mbiri chete.Zvimwe zvimiro zvekushivirira zvinopihwa sechikamu chezvikamu zvezita.
Nekuti ferrite magineti yakashandiswa kwemakumi emakore, vagadziri vazhinji vane mhete dzakagadzirirwa, masikweya uye zvimwe zvigadzirwa zvezvakajairwa maumbirwo uye saizi yekusarudza.
Nekuti ferrite ndeye ceramic zvinhu, pane chaizvo hapana dambudziko rekuora.Zvigadzirwa zvakapedzwa hazvidi kurapwa kwepamusoro kana kupfeka senge electroplating.
