Amazibuthe e-neodymium ahlala isikhathi esingakanani

Ozibuthe be-NdFeB, abaziwa nangokuthi omagnet be-NdFeB, bangamakristalu e-tetragonal akhiwe nge-neodymium, iron, ne-boron (Nd2Fe14B). Ozibuthe be-Neodymium bangozibuthe bakazibuthe abangapheli kakhulu abatholakala namuhla kanye nozibuthe bomhlaba abangavamile abasetshenziswa kakhulu.

Izakhiwo kazibuthe ze-NdFeB zingahlala isikhathi esingakanani?

Ozibuthe be-NdFeB banamandla amakhulu okuphoqelela, futhi ngeke kube khona ukukhishwa kazibuthe kanye nezinguquko kazibuthe ngaphansi kwemvelo yemvelo kanye nezimo ezijwayelekile zensimu kazibuthe. Uma sicabanga ukuthi imvelo ilungile, omagnet ngeke balahlekelwe ukusebenza okuningi ngisho nangemva kokusetshenziswa isikhathi eside. Ngakho-ke ekusebenzeni okusebenzayo, sivame ukungazinaki ithonya lesici sesikhathi kumagnetism.

Yiziphi izici ezizothinta impilo yesevisi yezibuthe ze-neodymium ekusebenziseni kwansuku zonke omazibuthe?

Kunezici ezimbili ezithinta ngqo impilo yesevisi ye-magnet.

Okokuqala ukushisa. Qiniseka ukuthi uyayinaka le nkinga lapho uthenga omazibuthe. Ozibuthe ochungechungeni lwe-N basetshenziswa kakhulu emakethe, kodwa bangasebenza kuphela endaweni engaphansi kwama-degree angama-80. Uma izinga lokushisa lidlula lokhu kushisa, i-magnetism izoba buthakathaka noma ikhishwe ngokuphelele. Njengoba insimu yamagnetic yangaphandle kazibuthe ifinyelela ekugcwaliseni futhi yakhe imigqa yokungeniswa kazibuthe eminyene, lapho izinga lokushisa langaphandle likhuphuka, ifomu elivamile lokunyakaza ngaphakathi kukazibuthe liyabhujiswa. Iphinde yehlise amandla okuphoqeleka angaphakathi kuzibuthe, okusho ukuthi, umkhiqizo omkhulu wamandla kazibuthe ushintsha nezinga lokushisa, futhi umkhiqizo wevelu ye-Br ehambisanayo kanye nevelu ye-H nakho kuyashintsha ngokufanele.

Okwesibili ukugqwala. Ngokuvamile, ingaphezulu lamagnethi we-neodymium lizoba nongqimba lokumboza. Uma ukugqoka kukazibuthe konakalisiwe, amanzi angangena kalula ngaphakathi kukazibuthe ngokuqondile, okuzokwenza ukuthi uzibuthe ugxume futhi kamuva kuholele ekwehleni kokusebenza kazibuthe. Phakathi kwabo bonke omazibuthe, amandla okumelana nokugqwala wezibuthe ze-neodymium aphakeme kunawabanye omazibuthe.

Ngifuna ukuthenga ozibuthe be-neodymium bempilo ende, kufanele ngimkhethe kanjani umenzi?

Iningi lozibuthe be-neodymium likhiqizwa eChina. Uma ufuna ukuthenga imikhiqizo yekhwalithi ephezulu, kuya ngamandla efektri. Mayelana nobuchwepheshe bokukhiqiza, okokusebenza kokuhlola, ukugeleza kwenqubo, usizo lobunjiniyela, umnyango we-QC nezitifiketi zesistimu yokuphathwa kwekhwalithi konke kungahlangabezana namazinga omhlaba. I-Fuzheng ivele ihlangabezane nazo zonke izimo ezingenhla, ngakho-ke kulungile ukusikhetha njengomkhiqizi wamagnetic we-neodymium wesifazane.
