Iimagnethi zeNdFeB, kwaziwa njengeiimagnethi ze-neodymium, ziphakathi kwezona magnethi zinamandla nezisetyenziswa kakhulu ehlabathini.Zenziwe ngokudityaniswa kwe-neodymium, i-iron, kunye ne-boron, nto leyo ekhokelela kumandla ombane onamandla.Nangona kunjalo, njengaye nawuphi na omnye umazibuthe, iimagnethi zeNdFeB zichaphazeleka kwi-demagnetization.Kweli nqaku, siza kuxoxa ngezinto eziphambili ezichaphazela i-demagnetization yemagnethi ye-NdFeB.
Ubushushu yenye yezinto eziphambili ezinokubangela demagnetization kwimagnethi ye-NdFeB.Ezi magnethi zine-aubushushu bokusebenza okuphezulu, ngaphaya koko baqala ukulahlekelwa iimpawu zabo zamagnetic.Ubushushu beCurie yindawo apho i-magnetic material idlula kwinguqu yesigaba, ekhokelela ekwehleni okukhulu kwi-magnetization yayo.Kwimagnethi ye-NdFeB, ubushushu beCurie bumalunga ne-310 degrees Celsius.Ke, ukusebenzisa umazibuthe kumaqondo obushushu akufutshane okanye ngaphezulu kwalo mda kunokukhokelela kwi-demagnetization.
Enye into ebalulekileyo echaphazela i-demagnetization yemagnethi ye-NdFeB yindawo yangaphandle yamagnetic.Ukuveza umazibuthe kwindawo eyomeleleyo yemagnethi echasayo kunokubangela ukuba iphulukane nemagnethi yayo.Le nto yaziwa ngokuba yi-demagnetizing.Amandla kunye nobude bentsimi yangaphandle idlala indima ebalulekileyo kwinkqubo ye-demagnetization.Ke ngoko, kubalulekile ukuphatha iimagnethi ze-NdFeB ngononophelo kwaye uthintele ukuzibeka esichengeni semagnethi eyomeleleyo enokubeka esichengeni iipropathi zazo zemagneti.
I-Corrosion ikwayinto ebalulekileyo enokukhokelela kwi-demagnetization yemagnethi ye-NdFeB.Ezi magnethi zenziwe ngealloyi zetsimbi, kwaye ukuba zithe zavezwa kukufuma okanye iikhemikhali ezithile, zinokugqwala.I-Corrosion yenza buthathaka isidima sokwakheka kwemagnethi kwaye inokubangela ilahleko yamandla ayo wemagnethi.Ukuthintela oku, iingubo ezifana ne-nickel, i-zinc, okanye i-epoxy zihlala zisetyenziselwa ukukhusela imagnethi kumswakama kunye nezinto ezidliwayo.
Uxinzelelo lomatshini yenye into enokubangela demagnetization kwimagnethi ye-NdFeB.Uxinzelelo olugqithisileyo okanye impembelelo inokuphazamisa ulungelelwaniso lwemimandla yamagnetic ngaphakathi kwemagnethi, okubangela ukuhla kwamandla ayo omagnetic.Ke ngoko, kubalulekile ukuphatha iimagnethi ze-NdFeB ngononophelo ukunqanda ukusebenzisa amandla agqithisileyo okanye ukuzifaka kwiimpembelelo zequbuliso.
Okokugqibela, ixesha ngokwalo linokuthi ngokuthe ngcembe libangele demagnetization kwiimagnethi zeNdFeB.Oku kwaziwa njengokuguga.Kwixesha elongeziweyo, iipropathi zemagneti zemagnethi zinokwehla ngokwendalo ngenxa yezinto ezahlukeneyo ezifana nokuguquguquka kweqondo lobushushu, ukuvezwa kwemimandla yangaphandle yemagnethi, kunye noxinzelelo lomatshini.Ukunciphisa iziphumo zokwaluphala, uvavanyo oluqhelekileyo kunye nokujongwa kweempawu zemagneti kuyacetyiswa.
Ukuqukumbela, izinto ezininzi zinokuchaphazela i-demagnetization yemagnethi ye-NdFeB, kubandakanya ubushushu, umhlaba wangaphandle wemagnethi, umhlwa, uxinzelelo lomatshini, kunye nokuguga.Ngokuqonda kunye nokulawula ngokusebenzayo ezi zinto, kuyenzeka ukugcina iipropathi ezinamandla zemagneti zeNdFeB zemagnethi kunye nokwandisa ubomi babo.Ukuphatha ngendlela eyiyo, ulawulo lobushushu, kunye nokukhuselwa kwindawo enomhlwa yingqwalasela ephambili ekugcineni ukusebenza kwemagnethi.
