Nguva pfupi yadarika, apo mitengo yezvinhu zvese zvemumba nemidziyo isina ferrous metal yakawanda iri kuderera, mutengo wemusika wepasi risingawanzo wave uchikura, kunyanya pakupera kwaGumiguru, uko mutengo wakafara uye basa revatengesi rakawedzera. . Semuenzaniso, spot praseodymium uye neodymium simbi yakaoma kuwana muna Gumiguru, uye kutenga kwepamusoro-soro kwave kuri tsika muindasitiri. Mutengo wePraseodymium neodymium metal wakasvika pa910,000 yuan/ton, uye mutengo wepraseodymium neodymium oxide wakachengetawo mutengo wakakwira we735,000 kusvika 740,000 yuan/ton.
Vaongorori vemusika vakati kukwira kwemitengo yepasi isingawanzo kukonzerwa neyakasanganiswa mhedzisiro yekuwedzera kuri kudiwa, kuderedzwa kwekupa uye kushomeka kwezvinhu. Nekusvika kwemwaka wepamusoro-soro muchikamu chechina, mitengo yepasi isingawanzo ive ichiri kukwira. Muchokwadi, chikonzero chekuwedzera uku kwemitengo yepasi isingawanzo kufambiswa nekudiwa kwesimba idzva. Mune mamwe mazwi, kukwira kwemitengo yepasi isingawanzo kukwira pane simba idzva.
Maererano nenhamba dzakakodzera, muzvikamu zvitatu zvekutanga zvegore rino, nyika yangu's itsva simba rekutengesa motokari yakasvika patsva yakakwirira. Kubva munaNdira kusvika munaGunyana, huwandu hwekutengesa kwemotokari nyowani dzemagetsi muChina hwaive 2.157 miriyoni, gore negore kuwedzera kwe1.9 nguva uye gore negore kuwedzera kwe1.4 nguva. 11.6% yekambani's itsva motokari yekutengesa.
Kugadzirwa kwemotokari itsva dzemagetsi kwakabatsira zvikuru indasitiri yepasi isingawanzo. NdFeB mumwe wavo. Iyi yepamusoro-inoshanda magineti zvinhu inonyanya kushandiswa muminda yemotokari, simba remhepo, zvemagetsi zvevatengi uye zvichingodaro. Mumakore achangopfuura, kudiwa kwemusika kweNdFeB kwakawedzera zvakanyanya. Zvichienzaniswa nekuchinja kwemaitiro ekushandisa mumakore mashanu apfuura, chikamu chemotokari dzemagetsi matsva chakapetwa kaviri.
Zvinoenderana nekusuma neAmerican nyanzvi David Abraham mubhuku "Periodic Table of Elements", yemazuva ano (itsva simba) mota dzakashongedzerwa nemagineti anopfuura makumi mana, anopfuura makumi maviri masensa, uye anoshandisa anenge 500 magiramu ezvisingawanzo zvinhu zvepasi. Imwe neimwe mota yehybrid inoda kushandisa kusvika 1.5 kilogiramu yezvinhu zvisingawanzo pasi magineti. Kune maautomaker makuru, kushomeka kuri kuitika kwechip kunongova zvikanganiso zvisina kusimba, zvipfupi, uye pamwe "zvisingawanzo pasi pamavhiri" mumaketani ekugovera.
Abrahama's statement haisi yekuwedzeredza. Indasitiri yepasi isingawanzo ichaita basa rinowedzera kukosha mukugadzirwa kwemotokari dzemagetsi matsva. Senge neodymium iron boron, chikamu chakakosha chemotokari nyowani dzesimba. Kutarisa kumusoro kwerwizi, neodymium, praseodymium uye dysprosium mupasi risingawanzo zvinhu zvakakosha zve neodymium iron boron. Kubudirira kwemusika mutsva wemotokari yemagetsi kuchatungamira mukuwedzera kwekudiwa kwezvinhu zvisingawanzo zvepasi senge neodymium.
Pasi pechinangwa chekabhoni peak uye kusarerekera kwekabhoni, nyika icharamba ichiwedzera marongero ayo kusimudzira kuvandudzwa kwemotokari dzemagetsi matsva. State Council ichangobva kupa "Carbon Peaking Action Plan muna 2030", iyo inokurudzira kukurudzira zvakasimba motokari itsva dzemagetsi, zvishoma nezvishoma kuderedza chikamu chemotokari dzechinyakare mukugadzirwa kwemotokari itsva uye kubata kwemotokari, kukurudzira dzimwe nzira dzemagetsi kune motokari dzevashandi vemaguta, uye kukurudzira magetsi nehydrogen. Fuel, liquefied natural gas powered heavy-duty freight cars. Chirongwa cheAction chakajekesawo kuti panosvika 2030, chikamu chemagetsi matsva uye akachena emagetsi emagetsi achasvika 40%, uye iyo kabhoni emission intensity pachikamu chesvondo kushandurwa kwemotokari dzinoshanda ichaderedzwa ne9,5% zvichienzaniswa ne2020.
Iyi ibhenefiti huru kune isingawanzo indasitiri yepasi. Zvinoenderana nefungidziro, mota nyowani dzemagetsi dzichaunza kukura kunoputika pamberi pa2030, uye indasitiri yemotokari yenyika yangu uye mashandisiro emotokari zvichavakazve kutenderedza magetsi matsva. Chakavanzika kuseri kweichi chinangwa chikuru ndiko kudiwa kukuru kwepasi isingawanzo. Iko kudiwa kwemotokari nyowani dzemagetsi kwakatoverengera gumi muzana yezvinodiwa zvemhando yepamusoro-soro zvigadzirwa zveNdFeB, uye ingangoita 30% yekuwedzera kwekuda. Tichifunga kuti kutengeswa kwemotokari nyowani dzemagetsi kuchasvika mamirioni gumi nemasere muna 2025, kudiwa kwemotokari nyowani kuchawedzera kusvika 27.4%.
Nekufambiswa mberi kwechinangwa che "dual carbon", hurumende dzepakati nedzenzvimbo dzichatsigira zvakasimba nekusimudzira kugadzirwa kwemotokari itsva dzemagetsi, uye nhevedzano yemitemo yekutsigira icharamba ichibudiswa uye kushandiswa. Naizvozvo, kungave kuri kuwedzera kwekudyara musimba idzva mukuita kwe "dual kabhoni" chinangwa, kana boom mumusika mutsva wemotokari yemagetsi, yakaunza kuwedzera kukuru.
