Yankho kwa mkulu kutentha demagnetization wa NdFeb

Anzanu omwe ali ndi chidziwitso cha maginito amadziwa zimenezoNdFeb Neodymium MagnetNthawi zambiri amadziwika kuti amagwira ntchito kwambiri komanso zotsika mtengo zamaginito mumakampani opanga maginito pakadali pano.minda ambiri chatekinoloje zapamwamba wasankha izo kupanga mbali zosiyanasiyana, monga chitetezo dziko asilikali, luso lamagetsi, zipangizo zachipatala, zipangizo zamagetsi ndi madera ena akukhudzidwa.More ndi mavuto ochulukirapo angapezeke, amene demagnetization wa ndfeb maginito wamphamvu mu kutentha kwapamwamba kwachititsa chidwi kwambiri. 

Chifukwa chiyani?NdFeb Permanent Magnetskufooka pa kutentha kwakukulu?

NdFeb degaussing pa kutentha kwambiri anatsimikiza ndi thupi lake structure.The maginito akhoza kwaiye ndi maginito, chifukwa ma elekitironi kunyamulidwa ndi zinthu atembenuza mozungulira atomu mu njira inayake, amene amapanga ena maginito mphamvu, ndiyeno zimakhudza. Koma ma elekitironi mozungulira ma atomu mogwirizana ndi malangizo okhazikitsidwa alinso ndi zinthu zina kutentha, zinthu zosiyanasiyana maginito akhoza kupirira kutentha ndi osiyana, mu nkhani ya kutentha kwambiri, zamagetsi adzapatuka njanji yoyambirira, chipwirikiti chodabwitsa, maginito zinthu pa nthawi ino m'dera maginito kukhumudwa, ndi demagnetization.

Komabe, kutentha kukana kwa NdFeb maginito mwina mozungulira baidu, ndiye, kuposa baidu adzaoneka chodabwitsa demagnetization, ngati kutentha ndi apamwamba, demagnetization chodabwitsa kwambiri.

Mayankho angapo ogwira ntchito kutentha demagnetization wa NdFeb, maginito kuperekedwa.

Choyamba, musati kuika NdFeb maginito mankhwala mu kutentha kwambiri, makamaka kulabadira kutentha ake ovuta, ndicho baidu, yake kusintha kutentha kwake ntchito chilengedwe, kuti kuchepetsa kuchitika kwa demagnetization.

Chachiwiri ndikuwongolera magwiridwe antchito azinthu pogwiritsa ntchito maginito a NdFeb kuchokera pamalingaliro aukadaulo, kuti athe kukhala ndi mawonekedwe a kutentha komanso osakhudzidwa ndi chilengedwe. 

Chachitatu, mutha kusankha zida zokakamiza kwambiri zomwe zimakhala ndi mphamvu ya maginito yofanana.Ngati sichoncho, muyenera kupereka pang'ono mphamvu ya maginito, ndikupeza zida zokhala ndi mphamvu zochepetsera maginito komanso mphamvu zokakamiza, koma palibenso, mutha kusankha samarium cobalt;kwa reversible demagnetization, kokhacobalt samariumzilipo.
