Limanete tsa NdFeB, e tsejoang hape e lemakenete a neodymium, ke tse ling tsa limakenete tse matla ka ho fetisisa le tse sebelisoang haholo lefatšeng. Li entsoe ka motsoako oa neodymium, tšepe le boron, e leng se hlahisang matla a matla a makenete. Leha ho le joalo, joalo ka makenete leha e le afe, limakete tsa NdFeB li ka hlaseloa habonolo ke demagnetization. Sehloohong sena, re tla tšohla lintlha tsa mantlha tse amang demagnetization ea limatlase tsa NdFeB.
Mocheso ke e 'ngoe ea lintlha tsa mantlha tse ka bakang demagnetization ho limakete tsa NdFeB. Limanete tsena li na leboholo ba mocheso o sebetsang, ho feta moo ba qalang ho lahleheloa ke matla a bona a khoheli. Thempereichara ea Curie ke ntlha eo matla a khoheli a fetohang mohato, e lebisang ho theoheng ho hoholo ha matla a eona a makenete. Bakeng sa makenete a NdFeB, mocheso oa Curie o ka bang 310 degrees Celsius. Kahoo, ho sebelisa makenete ka mocheso o haufi kapa ka holimo ho moeli ona ho ka lebisa ho demagnetization.
Ntho e 'ngoe ea bohlokoa e amang demagnetization ea limakete tsa NdFeB ke matla a khoheli a kantle. Ho pepesa makenete sebakeng se matla sa khoheli ho ka etsa hore e lahleheloe ke matla a eona. Ketsahalo ena e tsejoa e le demagnetizing. Matla le nako ea sebaka sa kantle li bapala karolo ea bohlokoa ts'ebetsong ea demagnetization. Ka hona, ho bohlokoa ho sebetsana le limatlase tsa NdFeB ka hloko le ho qoba ho li pepesetsa matla a khoheli a ka senyang thepa ea tsona ea khoheli.
Corrosion hape ke ntho ea bohlokoa e ka lebisang ho demagnetization ea limatlase tsa NdFeB. Limanete tsena li entsoe ka li-alloys tsa tšepe, 'me haeba li pepesehetse mongobo kapa lik'hemik'hale tse itseng, li ka senya. Corrosion e fokolisa sebopeho sa sebopeho sa makenete mme e ka fella ka tahlehelo ea matla a eona a khoheli. Ho thibela sena, hangata ho sebelisoa liaparo tse kang nickel, zinki kapa epoxy ho sireletsa limatlase ho tloha mongobo le linthong tse senyang.
Khatello ea mochini ke ntho e 'ngoe e ka bakang demagnetization ho limatlase tsa NdFeB. Khatello e feteletseng kapa tšusumetso e ka sitisa ho tsamaisana ha libaka tsa makenete ka har'a makenete, ho baka ho fokotseha ha matla a eona a khoheli. Ka hona, ho bohlokoa ho sebetsana le limakete tsa NdFeB ka hloko ho qoba ho sebelisa matla a feteletseng kapa ho li beha kotsing ea tšohanyetso.
Qetellong, nako ka boeona e ka boela ea baka demagnetization butle-butle ho limakete tsa NdFeB. Sena se tsejoa e le botsofali. Ha nako e ntse e feta, matla a makenete a ka senyeha ka tlhaho ka lebaka la maemo a fapaneng a joalo ka ho fetoha ha mocheso, ho pepesehela matla a khoheli a kantle le khatello ea maikutlo. Ho fokotsa litlamorao tsa botsofali, ho khothaletsoa tlhahlobo ea khafetsa le ho lekola thepa ea makenete ea makenete.
Qetellong, lintlha tse 'maloa li ka ama demagnetization ea limatlase tsa NdFeB, ho kenyelletsa mocheso, matla a khoheli a kantle, kutu, khatello ea maikutlo le botsofali. Ka ho utloisisa le ho laola lintlha tsena ka katleho, hoa khoneha ho boloka matla a khoheli a matla a makenete a NdFeB le ho lelefatsa bophelo ba bona. Ho tšoara hantle, taolo ea mocheso, le tšireletso khahlanong le tikoloho e senyang ke lintlha tsa bohlokoa ho boloka tšebetso ea makenete.
