Ozibuthe be-Neodymium, obeye aziwe njengoIzibuthe ze-NdFeB, ziphakathi kweomagnethi abaqine kakhulu unomphelaetholakalayo. Ahlanganiswe ngokuyinhloko i-neodymium, i-iron, ne-boron, lawa mazibuthe aguqule izimboni ezihlukahlukene ngenxa yamandla azo azibuthe avelele kanye nokuguquguquka. Nokho, kuphakama umbuzo ovamile: Ingabe izibuthe ze-neodymium zikhiqiza izinhlansi? Ukuze siphendule lo mbuzo, sidinga ukujula ngezakhiwo zaleziuzibuthes kanye nezimo lapho izinhlansi zingenzeka khona.
Izakhiwo ze-Neodymium Magnets
Ozibuthe be-Neodymium bangabakazibuthe basemhlabeni abangavamile abaziwa ngezici zabo eziphakeme kazibuthe. Banamandla kakhulu kunozibuthe abavamile, abafana nozibuthe be-ceramic noma i-alnico, okubenza bafaneleke ezinhlelweni ezisukela kumamotho kagesi ukuya emishinini ye-magnetic resonance imaging (MRI). Ozibuthe be-NdFeB bakweleta amandla abo ngesakhiwo sabo sekristalu esiyingqayizivele, esivumela ukuminyana okuphezulu kwamandla kazibuthe.
Ingabe izibuthe ze-neodymium zikhiqiza izinhlansi?
Ngamafuphi, omagnethi be-neodymium ngokwabo ngeke bakhiqize izinhlansi. Kodwa-ke, izinhlansi zingase zenzeke ngaphansi kwezimo ezithile, ikakhulukazi uma lezi zibuthe zisetshenziswa nezinto zokuhambisa noma kwezinye izinhlelo zokusebenza zemishini.
1. I-Mechanical Impact: Uma omagnethi ababili be-neodymium beshayisana ngamandla amakhulu, bangaveza izinhlansi ngenxa yokunyakaza okusheshayo nokungqubuzana phakathi kwendawo. Lokhu kungenzeka kakhulu uma ozibuthe bebakhulu futhi besinda, njengoba amandla e-kinetic ahilelekile emthelela angaba mkhulu. Izinhlansi aziwona umphumela wezakhiwo zikazibuthe, kodwa kunalokho ukuxhumana ngokomzimba phakathi kozibuthe.
2. Izicelo zikagesi: Ezinhlelweni lapho omagnethi be-neodymium besetshenziswa ezimotweni noma kumajeneretha, izinhlansi zingavela kumabhulashi noma kothintana nabo. Lokhu akubangelwa yizibuthe ngokwazo, kodwa kunalokho ekudluleni kwamanje ngokusebenzisa izinto ezisebenzayo. Uma omazibuthe beyingxenye yesistimu lapho kuvela khona i-arcing, izinhlansi zizokwenzeka, kodwa lena inkinga engahlobene nezakhiwo kazibuthe zikazibuthe.
3. I-Demagnetization: Uma uzibuthe we-neodymium engaphansi kokushisa okudlulele noma ingcindezi yomzimba, izolahlekelwa izici zayo kazibuthe. Kwezinye izimo, lokhu demagnetization kungaholela ekukhululweni kwamandla angase abonakale njengezinhlansi kodwa akuwona umphumela oqondile wezakhiwo zemvelo zikazibuthe.
Amanothi Okuphepha
Nakuba izibuthe ze-neodymium ziphephile ezinhlelweni eziningi, kufanele ziphathwe ngokucophelela. Inkambu yawo kazibuthe enamandla ingabangela ukulimala uma iminwe noma ezinye izitho zomzimba zibanjwa phakathi komazibuthe. Ukwengeza, lapho usebenza ngozibuthe abakhulu be-neodymium, umuntu kufanele aqaphele ukuthi kungenzeka kube nomthelela wemishini ongabangela izinhlansi.
Ezimweni lapho izinto ezivuthayo zikhona, kuyanconywa ukugwema izimo lapho omazibuthe bengaphansi kokushayisana noma ukungqubuzana. Izinyathelo ezifanele zokuphepha kufanele ngaso sonke isikhathi zithathwe uma uphatha ozibuthe abaqinile.
