Neodymium magineti anogara kwenguva yakareba sei

NdFeB magineti, anozivikanwawo seNdFeB magineti, ari tetragonal crystals akaumbwa neodymium, iron, uye boron (Nd2Fe14B).Neodymium magineti ndiwo anonyanya kushandiswa magineti anogara aripo nhasi uye anonyanya kushandiswa epasi magineti.

Inguva yakareba sei iyo magineti eNdFeB magineti anogona kugara kwenguva yakareba?

NdFeB magineti ane yakanyanya kumanikidza simba, uye hapazove nedemagnetization uye shanduko yemagineti pasi pechisikigo nharaunda uye general magineti mamiriro.Tichifunga kuti nharaunda ndeyechokwadi, magineti haazorasikirwe nekuita kwakawanda kunyangwe mushure mekushandisa kwenguva refu.Saka mukushandisa kunoshanda, isu tinowanzo kufuratira pesvedzero yenguva chinhu pane magineti.

Ndezvipi zvinhu zvichakanganisa hupenyu hwesevhisi yeneodymium magineti mukushandiswa kwemazuva ese kwemagineti?

Pane zvinhu zviviri zvaunokanganisa zvakananga hupenyu hwebasa remagineti.

Chokutanga kupisa.Iva nechokwadi chekuteerera kune dambudziko iri paunenge uchitenga magineti.N akatevedzana magineti anoshandiswa zvakanyanya mumusika, asi anogona chete kushanda munzvimbo iri pasi pe80 madhigirii.Kana tembiricha yakapfuura tembiricha iyi, iyo magineti ichave isina simba kana demagnetized zvachose.Sezvo iyo magineti yekunze magineti inosvika pakuzara uye yakagadzira mitsara yakaonda yemagineti induction, kana tembiricha yekunze yakwira, iyo yenguva dzose inofamba fomu mukati megineti inoparadzwa.Iyo zvakare inoderedza intrinsic yekumanikidza simba remagineti, kureva kuti, hombe yemagineti simba chigadzirwa chinoshanduka nekudziya, uye chigadzirwa cheiyo inoenderana Br kukosha uye H kukosha zvakare inochinja zvinoenderana.

Yechipiri ndiyo ngura.Kazhinji, pamusoro pemagineti neodymium ichava nedhiri yekuvhara.Kana iyo yekuputira pamagineti yakanganiswa, mvura inogona kupinda mukati megineti nyore nyore, izvo zvinozoita kuti magineti iite ngura uye zvozotungamira mukudzikira kwekuita kwemagineti.Pakati pemagineti ese, iyo corrosion resistance simba remagineti neodymium rakakwirira kudarika remamwe magineti.

Ndinoda kutenga magineti ehupenyu hurefu neodymium, ndinofanira kusarudza sei mugadziri?

Mazhinji emagetsi e neodymium anogadzirwa muChina.Kana iwe uchida kutenga zvigadzirwa zvemhando yepamusoro, zvinoenderana nesimba refekitari.Panyaya yetekinoroji yekugadzira, michina yekuyedza, kuyerera kwemaitiro, rubatsiro rweinjiniya, QC dhipatimendi uye zvemhando yepamusoro zvitupa zvese zvinogona kusangana nedzimwe nyika.Fuzheng inongosangana nemamiriro ese ari pamusoro, saka zvakanaka kutisarudza isu semugadziri wemagineti echikadzi neodymium.
