Yintoni impahla ye-PrNd?
I-PrNd impahla, eyaziwa ngokuba yi-Praseodymium-Neodymium, luhlobo lweizinto zomhlaba ezinqabileyoeye yafumana ingqwalasela ebalulekileyo kwiminyaka yakutshanje ngenxa yeempawu zayo ezimangalisayo zemagneti.Esi sixhobo siyinxalenye ephambili kwimveliso yamagnethi anamandla, ngakumbi iimagnethi ze-PrNd, ezisetyenziswa ngokubanzi kumashishini ahlukeneyo, kubandakanywa i-electronics, i-automotive, kunye namandla avuselelweyo.
Iimagnethi zomhlaba ezinqabileyo, eziquka iimagnethi ze-PrNd, zaziwa ngamandla azo akhethekileyo kunye neempawu zemagnethi.Zibalulekile ekwenziweni kweemveliso ezininzi, ukusukela kubathengi be-elektroniki ukuya kwizixhobo zonyango eziphambili.Iimpawu ezizodwa zePrNd imathiriyelisiyenze ibe sisixhobo esiyimfuneko kubuchwephesha banamhlanje kunye nokusungula izinto ezintsha.
Iimagnethi ze-PrNd zenziwe ngendibaniselwano yepraseodymium kunye neodymium, izinto ezimbini ezinqabileyo zomhlaba ezibonisa iimpawu ezinamandla zemagnethi.Ezi magnethi zidume ngokomelela kwemagnethi ephezulu, nto leyo ezenza zilungele usetyenziso olufuna umhlaba obambeneyo nonamandla wemagnethi.Ukusetyenziswa kwePrNd umazibutheiguqule uyilo kunye nokusebenza kwezixhobo ezahlukeneyo, ivumela uphuhliso lweemveliso ezincinci, ezikhaphukhaphu kunye nezisebenzayo.
Iimpawu ezikhethekileyo zemagnethi zemagnethi ze-PrNd zingabalelwa kulwakhiwo olulodwa lweathomu yepraseodymium kunye neodymium.Ezi zinto zineelektroni ezingasebenziyo, ezinegalelo kumhlaba wazo owomeleleyo wemagnethi.Xa idityaniswe ngohlobo lwemagnethi, imathiriyeli ye-PrNd ibonisa isakhono esimangalisayo sokutsala kunye nokubamba imirhumo yemagnethi, iyenza ibe sisixhobo esixabiseke kakhulu kwizicelo ezininzi zoshishino nezobuchwepheshe.
Enye yeenzuzo eziphambili zeemagnethi ze-PrNd kukunyanzeliswa kwabo okuphezulu, okubhekiselele ekukwazini kwabo ukuxhathisa i-demagnetization.Le propati ibenza bathembeke kakhulu kwaye bahlale ixesha elide, iqinisekisa ukuba umhlaba wemagnethi uhlala uzinzile ixesha elide lokusetyenziswa.Ngenxa yoko, iimagnethi ze-PrNd zisetyenziswa ngokubanzi kwizicelo apho zihambelana kwayeukusebenza okuthembekileyo kwamagneticIbalulekile, njengeenjini zombane, oomatshini bokucinga ngemagnethi (MRI) kunye nezahluli zemagnethi.
Ukongeza kumandla abo akhethekileyo omagnetic, iimagnethi zePrNd zikwaxatyiswa ngemveliso yazo yamandla aphezulu, nto leyo engumlinganiselo wobuninzi bamandla obunokubonelela ngemagnethi.Olu phawu lwenzaPrNd umazibutheesebenza kakuhle kakhulu ekuguquleni amandla ombane abe yintshukumo yoomatshini, nto leyo ebenza babaluleke kakhulu kuphuhliso lobuchwepheshe obuphambili, obunje ngezithuthi zombane, iiinjini zomoya, kunye neenkqubo zokutsalwa kwemagnethi.
Ukusetyenziswa okuxhaphakileyo kweemagnethi ze-PrNd kumashishini ahlukeneyo kugxininisa ukubaluleka kwazo ekuqhubeleni phambili ukuqhubela phambili kobuchwepheshe kunye nokusungula izinto ezintsha.Ukusuka ekomelezeni ukusebenza kwezithuthi zombane ukuya ekuvumeleni ukwenziwa kancinci kwezixhobo zombane, iimagnethi zePrNd zidlala indima ebalulekileyo ekubumbeni ilizwe lanamhlanje.
Nangona kunjalo, kubalulekile ukuqaphela ukuba ukuveliswa kweemagnethi ze-PrNd kuxhomekeke ekutsalweni nasekuqhutyweni kwezinto ezinqabileyo zomhlaba, ezinokuthi zibe neempembelelo zokusingqongileyo kunye ne-geopolitical.Ngaloo ndlela, iinzame ziyenziwa ukuphonononga izenzo ezizinzileyo zeimigodi yomhlaba enqabileyokunye nokuphuhlisa ezinye izinto ezinokunciphisa ukuthembela kwizinto ezinqabileyo zomhlaba.
Ukuqukumbela, izinto ze-PrNd, ngokukodwa kwifom ye-PrNd magnets, imele ilitye lembombo leteknoloji yanamhlanje, enika amandla angenakulinganiswa namagnetic kunye nokusebenza.Njengoko imfuno yemagnethi esebenza ngokuphezulu iqhubeka nokukhula, ukubaluleka kwezinto ze-PrNd ekuqhubeni izinto ezintsha kunye nenkqubela phambili yezobuchwepheshe ayinakugqithiswa.Ngophando oluqhubekayo kunye nophuhliso, izicelo ezinokubakho zeemagnethi ze-PrNd zilungele ukwandisa, ziqinisa ngakumbi indima yazo ekubumbeni ikamva leteknoloji kunye neshishini.
