Korodhka degdega ah ee qiimaha magnets-ka ee NdFeB sanadka 2021 wuxuu saameeyaa danaha dhammaan dhinacyada, gaar ahaan soosaarayaasha codsiyada hoose.Waxay aad u xiiseeyaan inay ogaadaan wax ku saabsan sahayda iyo baahida Neodymium Iron Boron magnets, si ay u horumariyaan qorshayaasha mashaariicda mustaqbalka oo ay u qaataan duruufo gaar ah qorshe ahaan.Hadda waxaanu soo bandhigi doonaa warbixin kooban oo falanqayn ah oo ku saabsan macluumaadka magnets NdFeB ee Shiinaha ee macaamiisheena, gaar ahaan kuwa soo saara korantada si loo tixraaco.
Sanadihii la soo dhaafay, wax soo saarka ee NdFeB qalabka magnetic joogto ah ee Shiinaha ayaa muujiyay isbeddel sii kordhaya.Magnets NdFeB Sinteredwaa badeecadaha caadiga ah ee gudaha NdFeB suuqa magnetka joogtada ah.Sida laga soo xigtay xogta Wasaaradda Warshadaha iyo Tignoolajiyada Warfaafinta, wax soo saarka NdFeB banaannada sintered iyo bond NdFeB magnets waa 207100 tan iyo 9400 tan siday u kala horreeyaan ee 2021. 2021, wax soo saarka guud ee NdFeB ee NdFeB magnet joogto ah ayaa gaadhay 2164500 ilaa 1. % sanadba sanadka ka dambeeya.
Qiimaha magnetka joogtada ah ee naadirka ah ee dhulka ayaa si degdeg ah u kacay tan iyo barta hoose ee bartamihii 2020, iyo qiimaha magnet dhulka dhif ah ayaa labanlaabmay dhamaadka 2021. Sababta ugu weyn ayaa ah in qiimaha alaabta ceeriin dhulka dhif ah, sida. Praseodymium, Neodymium, Dysprosium, Terbium, ayaa si degdeg ah u kacay.Dhamaadka 2021, qiimuhu wuxuu ku dhow yahay saddex laab qiimaha badhtamaha 2020. Dhinac, cudurka faafa wuxuu horseeday sahayda oo liidata.Dhanka kale, baahida suuqa ayaa si degdeg ah u korodhay, gaar ahaan tirada codsiyada suuqa cusub ee dheeraadka ah.Tusaale ahaan, dhammaan magnets-ka naadirka ah ee dhulka ee baabuurta tamarta cusub ee Shiinaha ayaa qiyaastii 6% ka ah wax-soo-saarka Neodymium magnet-ka ee 2021-ka. 2021, wax-soo-saarka baabuurta cusub ee tamarta ayaa kor u dhaafaya 3.5 milyan, iyadoo koror sannad-sannadka ah 160 %.Baabuurta rakaabka korontada ee saafiga ah ayaa ahaan doona qaabka caadiga ah ee baabuurta tamarta cusub.Sannadka 2021, 12000 oo tanWaxqabadka sare ee NdFeB magnetsayaa looga baahan yahay goobta baabuurta korontada.Waxaa lagu qiyaasaa in marka la gaaro 2025, heerka kobaca sanadlaha ah ee kororka tamarta cusub ee Shiinaha ee wax soo saarka tamarta cusub uu gaari doono 24%, wadarta wax soo saarka gawaarida tamarta cusub waxay gaari doontaa 7.93 milyan marka la gaaro 2025, iyo baahida loo qabo waxqabadka sare ee cusub ee naadirka dhulka Neodymium magnets wuxuu noqon doonaa 26700 oo tan.
Shiinaha hadda waa kan ugu weyn adduunkasoo saaraha ka mid ah magnets joogto ah dhulka dhif ah, wax soo saarkeeduna asal ahaan waxa ay ka sarreeyaan 90% wadarta guud ee caalamka sannadihii u dambeeyay.Dhoofintu waa mid ka mid ah kanaalada iibka ee ugu weyn ee alaabada magnetka joogtada ah ee dhulka naadir ee Shiinaha.Sannadka 2021, wadarta guud ee mugga dhoofinta ee alaabada magnetka joogtada ah ee dhulka dhifka ah ee Shiinaha waa 55000 tan, koror ah 34.7% marka loo eego 2020 sababta koritaanka la taaban karo ee Shiinaha ee dhul dhif ah dhoofinta magnet joogto ah.
Yurub, Ameerika iyo Bariga Aasiya waxay had iyo jeer ahaayeen suuqyada dhoofinta ee ugu weyn ee Shiinaha alaabada magnet Neodymium ee naadirka ah.2020, wadarta guud ee dhoofinta tobanka waddan ee ugu sarreeya waxay dhaaftay 30000 tan, taasoo ka dhigan 85% wadarta;wadarta guud ee wax dhoofinta ee shanta wadan ee ugu sareysa ayaa dhaaftay 22000 oo tan, taasoo ka dhigan 63% wadarta guud.
Xaddiga suuqa dhoofinta ee magnets-ka joogtada ah ee dhulku waa mid sarreeya.Marka loo eego aragtida dhoofinta ee shuraakada waaweyn ee ganacsiga, tiro badan oo ah magnets-ka naadirka ah ee Shiinaha ee naadirka ah ayaa loo dhoofiyaa Yurub, Mareykanka iyo Bariga Aasiya, kuwaas oo intooda badan ah wadamo horumaray oo leh heer saynis iyo teknolojiyad sare.Tusaale ahaan, xogta dhoofinta ee 2020, shanta waddan ee ugu sarreeya waa Jarmalka (15%), Maraykanka (14%), Kuuriyada Koonfureed (10%), Vietnam iyo Thailand.Waxaa la sheegay in meesha ugu dambeysa ee magnets-ka joogtada ah ee dhulka naadirka ah ee loo dhoofiyo Koonfur-bari Aasiya ay tahay inta badan Yurub iyo Ameerika.
