Imagnethi yeNeodymium, kwaziwa njengeIimagnethi zeNdFeB, ziphakathi kweiimagnethi ezinamandla ezisisigxinaekhoyo. Idityaniswe ikakhulu i-neodymium, intsimbi, kunye ne-boron, ezi magnethi ziye zaguqula amashishini ahlukeneyo ngenxa yamandla azo abalaseleyo emagnethi kunye nokuguquguquka. Nangona kunjalo, umbuzo oqhelekileyo uphakama: Ngaba iimagnethi ze-neodymium zivelisa iintlantsi? Ukuphendula lo mbuzo, kufuneka singene nzulu kwiimpawu zeziumazibuthes kunye neemeko apho iintlantsi zinokuthi zenzeke.
Iipropati ze-Neodymium Magnets
Iimagnethi zeNeodymium zezemagnethi zomhlaba ezinqabileyo ezaziwa ngeempawu zazo eziphezulu zemagneti. Zomelele kakhulu kunemagnethi eqhelekileyo, enjengemagnethi yeceramic okanye ialnico, izenza zilungele usetyenziso olususela kwiinjini zombane ukuya koomatshini bokucinga ngemagnethi (MRI). Iimagnethi ze-NdFeB zityala amandla azo kubume bekristale obukhethekileyo, obuvumela ukuxinana okuphezulu kwamandla kazibuthe.
Ngaba imagnethi ye-neodymium ivelisa iintlantsi?
Ngokufutshane, iimagnethi ze-neodymium ngokwazo aziyi kuvelisa iintlantsi. Nangona kunjalo, iintlantsi zinokwenzeka phantsi kweemeko ezithile, ngakumbi xa ezi magnethi zisetyenziswa ngezinto zokuqhuba okanye kwizicelo ezithile zoomatshini.
1. Impembelelo yoomatshini: Xa iimagnethi ezimbini ze-neodymium zingqubana ngamandla amakhulu, zinokuvelisa iintlantsi ngenxa yentshukumo ekhawulezileyo kunye nokungqubana phakathi komphezulu. Oku kunokwenzeka ngakumbi ukuba iimagnethi zinkulu kwaye zinzima, njengoko amandla ekinetic abandakanyekayo kwimpembelelo anokuba mkhulu. Iintlantsi aziyosiphumo seempawu zemagnethi umazibuthe, kodwa kukudibana kwenyama phakathi kwemagnethi.
2. Usetyenziso loMbane: Kwiinkqubo apho imagnethi ye-neodymium isetyenziswa kwiimotor okanye iijenereyitha, iintlantsi zinokuvela kwiibhrashi okanye kunxibelelwano. Oku akubangelwa yimagnethi ngokwazo, kodwa kunoko kwindlela yangoku ngokusebenzisa izinto zokuqhuba. Ukuba iimagnethi ziyinxalenye yenkqubo apho i-arcing isenzeka khona, iintlantsi ziya kwenzeka, kodwa lo ngumba onganxulumananga neempawu zemagnethi zemagnethi.
3. I-Demagnetization: Ukuba umazibuthe we-neodymium uphantsi kobushushu obugqithisileyo okanye uxinzelelo lwasemzimbeni, iya kuphulukana neempawu zayo zemagnethi. Kwezinye iimeko, oku demagnetization kunokukhokelela ekukhululweni kwamandla anokuthi abonwe njengeentlantsi kodwa ayisosiphumo esithe ngqo seempawu zendalo zemagnethi.
Amanqaku okhuseleko
Ngelixa iimagnethi ze-neodymium zikhuselekile kwizicelo ezininzi, kufuneka ziphathwe ngononophelo. Imagnethi eyomeleleyo inokubangela ukwenzakala ukuba iminwe okanye amanye amalungu omzimba abanjwe phakathi kwemagnethi. Ukongeza, xa usebenza ngeemagnethi ezinkulu ze-neodymium, umntu kufuneka aqonde ukuba kunokwenzeka ukuba nefuthe lomatshini elinokubangela iintlantsi.
Kwiimeko apho izinto ezinokutsha zikhona, kuyacetyiswa ukuba uphephe iimeko apho iimagnethi ziphantsi kongquzulwano okanye ukungqubana. Amanyathelo afanelekileyo okhuseleko kufuneka asoloko ethathwa xa uphethe iimagnethi ezinamandla.
