Ukunyuka ngokukhawuleza kwexabiso lemagnethi ye-NdFeB ngo-2021 kuchaphazela umdla wawo onke amaqela, ngakumbi abavelisi bezicelo ezisezantsi. Banqwenela ukwazi malunga nokubonelela kunye nemfuno yemagnethi ye-Neodymium Iron Boron, ukuze benze izicwangciso kwangaphambili kwiiprojekthi ezizayo kwaye bathathe iimeko ezizodwa njengesicwangciso. Ngoku siza kubonisa ingxelo yohlalutyo olufutshane kulwazi lweemagnethi ze-NdFeB e-China kubathengi bethu, ngakumbi abavelisi beemoto zombane ukuze babhekiselele.
Kwiminyaka yakutshanje, imveliso ye-NdFeB esisigxina ye-magnetic materials e-China ibonise indlela ekhulayo.Sintered NdFeB umazibuthezezona mveliso ziphambili kwimakethi yemagnethi yasekhaya yeNdFeB. Ngokutsho kwedatha yoMphathiswa wezoShishino kunye neTekhnoloji yoLwazi, imveliso ye-sintered NdFeB blanks kunye ne-bond NdFeB magnets yi-207100 yeetoni kunye ne-9400 yeetoni ngokulandelelanayo ngo-2021. Ngo-2021, isiphumo esipheleleyo se-NdFeB ye-magnetic blanks ifikelela kwi-216500 yeetoni. % unyaka ngonyaka.
Ixabiso lemagnethi enqabileyo yomhlaba esisigxina inyuke ngokukhawuleza ukususela kwindawo ephantsi phakathi kwe-2020, kwaye ixabiso lemagnethi yomhlaba enqabileyo liphindwe kabini ekupheleni kuka-2021. Esona sizathu kukuba amaxabiso ezinto ezinqabileyo zomhlaba, ezifana I-Praseodymium, i-Neodymium, i-Dysprosium, i-Terbium, iphakame ngokukhawuleza. Ekupheleni kuka-2021, ixabiso lijikeleze kathathu ixabiso phakathi kuka-2020. Kwelinye icala, ubhubhane ukhokelele ekuboneleleni kakubi. Ngakolunye uhlangothi, imfuno yemarike ikhule ngokukhawuleza, ngakumbi inani lezicelo ezongezelelweyo zemarike. Ngokomzekelo, zonke iimagnethi ezinqabileyo zomhlaba ezisisigxina zezithuthi zamandla amatsha eChina zithatha malunga ne-6% ye-sintered Neodymium magnet output ngo-2021. Ngo-2021, imveliso yezithuthi zamandla amatsha idlula i-3.5 yezigidi, ngokukhula konyaka-ngonyaka we-160. %. Iimoto zabakhweli zombane ezisulungekileyo ziya kuhlala ziyimodeli eqhelekileyo yezithuthi zamandla amatsha. Ngo-2021, iitoni ze-12000 zeiimagnethi zeNdFeB ezisebenza kakhuluziyafuneka kwindawo yezithuthi zombane. Kuqikelelwa ukuba ngo-2025, isantya sokukhula komdibaniso wonyaka wemveliso entsha yesithuthi samandla eTshayina siya kufikelela kwi-24%, imveliso iyonke yezithuthi zamandla amatsha iya kufikelela kwi-7.93 yezigidi ngo-2025, kunye nemfuno yokusebenza okuphezulu okunqabileyo komhlaba we-Neodymium umazibuthe uya kuba. 26700 iitoni.
I-China ngoku lelona lizwe likhuluumvelisi weemagnethi zomhlaba ezinqabileyo ezisisigxina, kwaye imveliso yayo ihleli ingaphezulu kwe-90% yetotali yehlabathi kwiminyaka yakutshanje. Ukuthumela ngaphandle yenye yeendlela eziphambili zentengiso yeemveliso zemagnethi ezisisigxina emhlabeni eTshayina. Ngo-2021, isixa esipheleleyo sokuthumela ngaphandle kwemveliso yamagnethi yomhlaba onqabileyo waseTshayina ziitoni ezingama-55000, ukwanda ngama-34.7% ngaphezulu konyaka ka-2020. Ngo-2021, imeko yobhubhane yaphesheya yathomalalisa, kunye nokubuyiselwa kwemveliso kunye nokukhula kwemfuno yokuthengwa kwamashishini aphesheya kolwandle yeyona nto iphambili. isizathu sokukhula okubonakalayo kokuthengiswa kwemagnethi yomhlaba osisigxina waseTshayina.
IYurophu, iMelika kunye neMpuma ye-Asiya bezisoloko ziziimarike eziphambili zokuthumela ngaphandle kwemveliso yemagnethi yaseTshayina yeNeodymium. Ngo-2020, inani elipheleleyo lokuthumela ngaphandle kumazwe alishumi aphezulu lidlule iitoni ezingama-30000, libalelwa kwi-85% yetotali; Umthamo opheleleyo wokuthumela kumazwe amahlanu aphambili ugqithise iitoni ezingama-22000, ezibalelwa kuma-63% etotali.
Uxinaniso lwemarike yokuthumela ngaphandle yeemagnethi zomhlaba ezinqabileyo ezisisigxina ziphezulu. Ukusuka kwimbono yokuthengisa kumazwe angaphandle ukuya kumaqabane aphambili orhwebo, inani elikhulu leemagnethi zomhlaba ezinqabileyo zaseTshayina zithunyelwa eYurophu, eMelika naseMpuma Asia, uninzi lwawo ingamazwe aphuhlileyo anenqanaba eliphezulu lezenzululwazi nobuchwepheshe. Ukuthatha idatha yokuthumela ngaphandle kwe-2020 njengomzekelo, amazwe amahlanu aphezulu yiJamani (15%), i-United States (14%), iSouth Korea (10%), iVietnam neThailand. Kuxelwe ukuba indawo yokugqibela yokusingwa kweemagnethi zomhlaba ezinqabileyo ezithunyelwa ngaphandle kuMzantsi-mpuma Asia ikakhulu yiYurophu neMelika.
