Yikuphi okufanele ngikhethe phakathi kwemikhiqizo ye-SmCo nemikhiqizo ye-NdFeB?

Emphakathini wanamuhla lapho izinto ezisetshenziswa kazibuthe zisetshenziswa kabanzi, yomibili imikhiqizo ye-samarium cobalt nemikhiqizo ye-neodymium iron boron idlala izindima ezihlukene. Kwabaqalayo embonini, kubaluleke kakhulu ukukhetha impahla evumelana nomkhiqizo wakho. Namuhla, ake sibheke ngokujulile izici zalezi zinto ezimbili ezihlukene futhi sibone ukuthi iyiphi efanelekela izidingo zakho.

1. Ukuqhathanisa ukusebenza

Izakhiwo kazibuthe

I-NdFeB iyizinto zikazibuthe eziqine kakhulu ezaziwayo ezinomkhiqizo wamandla kazibuthe ophakeme kakhulu. Lokhu kuyenza ibe yinhle kakhulu ezimeni zohlelo ezidinga insimu enamandla kazibuthe. Isibonelo, emkhakheni wamamotho, amamotho asebenzisa izibuthe ezihlala njalo ze-NdFeB angakha i-torque enkulu futhi anikeze amandla aqinile emishini. Amandla kazibuthe we-SmCo odonsa unomphela akufanele athathwe kancane. Bangakwazi ukugcina ukuzinza okuhle kazibuthe ezindaweni zokushisa okuphezulu. Lesi sici se-SmCo siyenza igqame kwezinye izindawo zezimboni ezikhethekile ezinezidingo zokushisa eziphezulu.

Ukuqina kwezinga lokushisa

Enye yezinzuzo ezinkulu zemikhiqizo ye-SmCo ukuzinza kwayo okuhle kakhulu kwezinga lokushisa. Ezimweni zokushisa okuphezulu, ukubola kazibuthe kamagnethi unomphela we-SmCo kuncane kakhulu kunokwe-NdFeB. Ngokuphambene, nakuba i-NdFeB inezici ezinamandla kazibuthe, ukubekezelelana kwayo kwezinga lokushisa akunamandla, futhi ukukhishwa kazibuthe okungenakuguqulwa kungase kwenzeke emazingeni okushisa aphezulu.

Ukumelana nokugqwala

Mayelana nokumelana nokugqwala, izinto ze-SmCo zisebenza kangcono kwezinye izindawo zegesi enomswakama negqwalayo ngenxa yezakhiwo zazo zamakhemikhali ezizinzile. Kodwa-ke, uma izinto ze-NdFeB zingenazo izimbotshana zokuzivikela ezifanele, zisengozini yokugqwala ezindaweni ezifanayo, okuthinta ukusebenza kwazo nempilo yesevisi. Kodwa-ke, ngokuthuthukiswa kobuchwepheshe bokwelapha okungaphezulu, ukumelana nokugqwala kwe-NdFeB nakho kuyathuthuka kancane kancane.

2. Izinkambu zokufaka isicelo

Izinkambu zokufaka izicelo zemikhiqizo ye-SmCo

Izinto zikazibuthe ezihlala njalo zeSamarium cobalt zisetshenziswa kabanzi emikhakheni ephezulu efana ne-aerospace, ezempi, kanye nezokwelapha. Ohlelweni lokulawula lezinjini zezindiza, omazibuthe be-SmCo abangapheli bangasebenza ngokuzinza kumazinga okushisa aphezulu nasezindaweni eziyinkimbinkimbi zokudlidliza kwemishini ukuze kuqinisekiswe ukulawula okunembile kwenjini. Ohlelweni lokuqondisa imicibisholo kanye nezingxenye zokulawula isimo sengqondo samasathelayithi emkhakheni wezempi, izinto ze-SmCo nazo zithandwa ngenxa yokunemba kwazo okuphezulu nokuzinza okuphezulu. Emishinini yezokwelapha, njengezingxenye ezibalulekile kazibuthe emishinini ye-magnetic resonance imaging (MRI), ukusetshenziswa kozibuthe be-SmCo unomphela kuqinisekisa ukunemba kwezinto zokusebenza ngaphansi kwezimo zokusebenza zesikhathi eside nezinamandla aphezulu.

Izinkambu zohlelo lokusebenza lwemikhiqizo ye-NdFeB

Izinto zikazibuthe ze-NdFeB zisetshenziswe kabanzi emkhakheni wezakhamuzi ngenxa yezakhiwo zazo ezinamandla kazibuthe kanye nezindleko eziphansi kakhulu. Isibonelo, emikhiqizweni yethu evamile yabathengi be-elekthronikhi njengama-hard drive, izipikha zefoni ephathekayo, nama-headphones, omazibuthe baphakade be-NdFeB babahlinzeka ngendawo encane futhi enamandla kazibuthe. Ezimotweni zezimoto zamandla amasha, ukusetshenziswa kwe-NdFeB kuphinde kwathuthukisa kakhulu ukusebenza kahle kwezinjini futhi kwakhuthaza ukuthuthukiswa kwemboni yezimoto zamandla amasha. Ngaphezu kwalokho, i-NdFeB iphinde ibambe iqhaza elibalulekile kumamotho ahlukahlukene, izinzwa neminye imishini emkhakheni wokuzenzakalelayo wezimboni.

3. Izici zezindleko

Izindleko zezinto ezingavuthiwe

Izingxenye eziyinhloko zezinto zikazibuthe ze-SmCo ezihlala unomphela, i-samarium ne-cobalt, ziyizakhi zensimbi ezingavamile uma kuqhathaniswa, futhi izindleko zazo zokumbiwa kwezimayini nokucwengwa ziphezulu, okuholela ezindlekweni eziphakeme zezinto ezingavuthiwe zemikhiqizo ye-SmCo. Phakathi kwezingxenye eziyinhloko ze-NdFeB, i-neodymium, insimbi ne-boron, insimbi ne-boron yizinto ezivamile futhi ezishibhile. Nakuba i-neodymium futhi iyisici somhlaba esiyivelakancane, i-NdFeB inezinzuzo ezithile ezindlekweni zempahla eluhlaza uma iqhathaniswa ne-SmCo.

Izindleko zokucubungula

Ngesikhathi sokucutshungulwa, izinto ze-SmCo zinzima ukucutshungulwa ngenxa yokuqina kwazo okuphezulu nezinye izici, futhi izindleko zokucubungula ziphakeme kakhulu. Izinto ze-NdFeB zilula ukucubungula, kodwa ngenxa ye-oxidation yazo elula nezinye izici, izinyathelo ezikhethekile zokuzivikela ziyadingeka ngesikhathi sokucubungula, okwandisa izindleko zokucubungula ngezinga elithile.

4. Ungakukhethela kanjani umkhiqizo ofanele

Cabangela izinga lokushisa lokusebenza

Uma umkhiqizo usetshenziswa endaweni yokushisa ephezulu, efana nangaphezulu kuka-150 ℃ noma ngaphezulu, njengasezimbonini ezinezinga lokushisa eliphezulu nezisetshenziswa kazibuthe ezizungeze izinjini ze-aerospace, imikhiqizo ye-samarium cobalt iyisinqumo esifaneleka kakhudlwana. Ngoba ukuzinza kwayo emazingeni okushisa aphezulu kungaqinisekisa ukusebenza okuzinzile kwesikhathi eside futhi kugweme izinkinga ze-demagnetization ezibangelwa ukunyuka kwezinga lokushisa. Uma izinga lokushisa lokusebenza likugumbi lokushisa elijwayelekile noma lingaphansi kuka-100 ℃, njengemikhiqizo eminingi ye-elekthronikhi engavamile, izinjini ezijwayelekile zezimboni, njll., imikhiqizo ye-NdFeB ingahlangabezana nezidingo futhi inganikeza ukudlala okugcwele ezindaweni zayo eziphakeme kazibuthe.

Cabangela izidingo zokumelana nokugqwala

Uma umkhiqizo uzosetshenziswa endaweni eswakeme, enegesi ebolayo, njengezingxenye kazibuthe emishinini esendaweni efana nolwandle nezitshalo zamakhemikhali, ukumelana nokugqwala kwempahla kudinga ukucatshangelwa. Ukuzinza kwamakhemikhali we-samarium cobalt impahla ngokwayo kwenza kube nenzuzo enkulu kule ndawo. Kodwa-ke, uma umkhiqizo we-NdFeB uphathwa ngengubo yokuvikela esezingeni eliphakeme, ungahlangabezana nezidingo zokumelana nokugqwala ngokwezinga elithile. Ngalesi sikhathi, kuyadingeka ukuthi ucabangele ngokuphelele izindleko nomphumela wokuvikela ongawukhetha.

Ukukala isabelomali sezindleko

Uma izindleko kungesona isici esinqunyelwe esiyinhloko, futhi izidingo zokusebenza nokuzinza ziphakeme kakhulu, njengamasosha, imishini yezokwelapha esezingeni eliphezulu kanye neminye imikhakha, izinga eliphezulu kanye nokuzinza kwemikhiqizo ye-samarium cobalt kungaqinisekisa ukusebenza okuthembekile kwe imishini. Kodwa-ke, uma kungumkhiqizo omkhulu wemikhiqizo yabantu, ukulawulwa kwezindleko kubalulekile. Imikhiqizo ye-NdFeB inganciphisa ngempumelelo izindleko ngenkathi ihlangabezana nezidingo zokusebenza ngezindleko zayo zezinto ezingavuthiwe eziphansi kakhulu kanye nezindleko zokucubungula.

Isidingo semakethe

Kwezinye izinhlelo zokusebenza ezidinga ukunemba nokuqina kwenkundla kazibuthe ephezulu kakhulu, njengamasistimu okuqondisa imicibisholo nezingxenye kazibuthe kumishini yokuhlola yezokwelapha enembayo, ukunemba okuphezulu nokusebenza okuzinzile kwakazibuthe kwemikhiqizo ye-samarium cobalt kuhambisana kakhulu nezidingo. Kwamanye amamotho ajwayelekile ezimboni, ama-electronics abathengi, njll. angadingi ukunemba okuphezulu kakhulu kodwa adinga amandla kazibuthe amakhulu, imikhiqizo ye-neodymium iron boron ingawenza kahle umsebenzi.
Awukho umehluko ophelele phakathi kwemikhiqizo ye-samarium cobalt nemikhiqizo ye-neodymium iron boron. Lapho ukhetha lezi zinto ezimbili ezinhle kakhulu kazibuthe, udinga ukwenza ukuqhathanisa okuphelele. Ukwabelana okungenhla kuthemba ukusiza wonke umuntu ukuthi athole imikhiqizo ehlangabezana nezidingo zabo!
