Iyini impahla ye-PrNd?
Impahla ye-PrNd, eyaziwa nangokuthi i-Praseodymium-Neodymium, iwuhlobo lweizinto zomhlaba ezingavamileeye yathola ukunakwa okuphawulekayo eminyakeni yamuva ngenxa yezakhiwo zayo ezimangalisayo zamagnetic.Lezi zinto ziyingxenye ebalulekile ekukhiqizweni kozibuthe abanamandla, ikakhulukazi ozibuthe be-PrNd, asetshenziswa kakhulu ezimbonini ezihlukahlukene, okuhlanganisa izinto zikagesi, ezezimoto, namandla avuselelekayo.
Ozibuthe bomhlaba abangavamile, kuhlanganise nozibuthe be-PrNd, baziwa ngamandla abo angavamile kanye nezakhiwo kazibuthe.Zibalulekile ekwenziweni kwemikhiqizo eminingi, kusukela kumishini kagesi ethengwayo kuye kwezisezingeni eliphezulu.Izici eziyingqayizivele zePrNd impahlayenze ibe yinsiza ebalulekile yobuchwepheshe besimanje kanye nokusungula izinto ezintsha.
Ozibuthe be-PrNd bakhiwe ngenhlanganisela ye-praseodymium ne-neodymium, izingxenye ezimbili zomhlaba eziyivelakancane ezibonisa izici ezinamandla kazibuthe.Laba zibuthe baziwa ngamandla abo kazibuthe aphezulu, okubenza bafaneleke ezinhlelweni ezidinga insimu ehlangene futhi enamandla kazibuthe.Ukusetshenziswa kwePrNd omazibutheiguqule ukwakheka nokusebenza kwamadivayisi ahlukahlukene, ivumela ukuthuthukiswa kwemikhiqizo emincane, elula, nesebenza kahle kakhulu.
Izici ezihlukile kazibuthe zikamabuthe be-PrNd zingabalulwa esakhiweni se-athomu esiyingqayizivele se-praseodymium ne-neodymium.Lezi zakhi zinama-electron angabhanqiwe, afaka isandla endaweni yawo enamandla kazibuthe.Uma kuhlanganiswe ngendlela kazibuthe, okubalulekile kwe-PrNd kukhombisa ikhono elimangalisayo lokuheha nokubamba amashaji kazibuthe, okuyenza insiza ebaluleke kakhulu yezinhlelo zokusebenza eziningi zezimboni nezobuchwepheshe.
Enye yezinzuzo ezibalulekile zozibuthe be-PrNd ukuphoqelela kwabo okuphezulu, okubhekisela emandleni abo okumelana nokukhishwa kazibuthe.Lesi sakhiwo sizenza zithembeke kakhulu futhi ziqine, iqinisekisa ukuthi insimu kazibuthe ihlala izinzile phakathi nesikhathi eside sokusebenzisa.Ngenxa yalokho, omazibuthe be-PrNd basetshenziswa kabanzi ezinhlelweni lapho kungaguquki futhiukusebenza okuthembekile kazibuthekubalulekile, njengakumamotho kagesi, imishini ye-magnetic resonance imaging (MRI) kanye nezihlukanisi kazibuthe.
Ngaphezu kwamandla kazibuthe angavamile, omazibuthe be-PrNd nabo baziswa ngomkhiqizo wabo wamandla aphezulu, okuyisilinganiso sobuningi bamandla obunganikezwa uzibuthe.Lesi sici senzaPrNd omazibutheasebenza kahle kakhulu ekuguquleni amandla kagesi abe ukunyakaza kwemishini, okuwenza abaluleke kakhulu ekuthuthukisweni kobuchwepheshe obusezingeni eliphezulu, njengezimoto zikagesi, izinjini zomoya, nezinhlelo zokudonsa kazibuthe.
Ukusetshenziswa okusabalele kozibuthe be-PrNd ezimbonini ezihlukahlukene kugcizelela ukubaluleka kwabo ekuqhubekiseni intuthuko yezobuchwepheshe kanye nokusungula izinto ezintsha.Kusukela ekuthuthukiseni ukusebenza kwezimoto zikagesi ukuya ekunikeni amandla ukwenziwa kancane kwezinto zikagesi, omagnethi be-PrNd badlala indima ebalulekile ekulolongeni umhlaba wesimanjemanje.
Kodwa-ke, kubalulekile ukuqaphela ukuthi ukukhiqizwa kozibuthe be-PrNd kuncike ekukhishweni nasekucutshungulweni kwezinto ezingavamile zomhlaba, ezingaba nemithelela yemvelo kanye ne-geopolitical.Ngakho-ke, kwenziwa imizamo yokuhlola izinqubo ezisimeme zeizimayini zomhlaba ezingavamilekanye nokuthuthukisa ezinye izinto ezinganciphisa ukuthembela ezintweni ezingavamile zomhlaba.
Sengiphetha, impahla ye-PrNd, ikakhulukazi esesimweni sikamazibuthe we-PrNd, imele insika yobuchwepheshe besimanje, enikeza amandla kazibuthe angenakuqhathaniswa nokusebenza.Njengoba isidingo sikamazibuthe asebenza kahle kakhulu siqhubeka sikhula, ukubaluleka kwempahla ye-PrNd ekuqhubekiseni uguquko olusha kanye nenqubekelaphambili yobuchwepheshe ngeke kwaziswe.Ngocwaningo oluqhubekayo nentuthuko, ukusetshenziswa okungaba khona komagnethi be-PrNd sekumi ngomumo ukwanda, kuqinise indima yabo ekulolongeni ikusasa lobuchwepheshe nezimboni.
