Tsoomfwv Meskas Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam tau tshaj tawm rau lub Cuaj Hlis 24 tias nws tau pib "232 kev tshawb nrhiav" seb puas yuav xa cov hlau nplaum Neodymium-hlau-boron mus tas li (Neodymium-iron-boron cov hlau nplaum ruaj khov) ua rau lub teb chaws ruaj ntseg ntawm Tebchaws Meskas.Qhov no yog thawj "232 kev tshawb nrhiav" pib los ntawm Biden thawj coj txij li thaum nws los ua haujlwm.Tsoomfwv Meskas Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam tau hais tias NdFeB cov khoom siv hlau nplaum ruaj khov yog siv rau hauv lub tebchaws tseem ceeb kev ruaj ntseg xws li cov dav hlau dav hlau thiab cov kev taw qhia missile, cov txheej txheem tseem ceeb xws li tsheb hluav taws xob thiab cua turbines, nrog rau cov khoos phis tawj hard drive, khoom siv suab, cov khoom siv sib nqus resonance. thiab lwm yam teb.
Thaum Lub Ob Hlis Ntuj xyoo no, Thawj Tswj Hwm Biden tau hais kom tsoomfwv cov koom haum ua 100-hnub tshuaj xyuas cov khoom siv ntawm plaub yam khoom tseem ceeb: semiconductors, cov ntxhia hauv ntiaj teb tsis tshua muaj, roj teeb muaj peev xwm loj rau tsheb fais fab, thiab tshuaj.Hauv 100-hnub cov txiaj ntsig tau xa mus rau Biden thaum Lub Rau Hli 8, nws raug nquahu kom US Department of Commerce soj ntsuam seb puas yuav tshuaj xyuas cov hlau nplaum neodymium raws li Tshooj 232 ntawm Txoj Cai Kev Lag Luam Kev Lag Luam ntawm 1962. Daim ntawv tshaj tawm tau taw qhia tias cov hlau nplaum neodymium ua si. lub luag haujlwm tseem ceeb hauv lub cev muaj zog thiab lwm yam khoom siv, thiab tseem ceeb rau kev tiv thaiv hauv tebchaws thiab kev siv pej xeem kev lag luam.Txawm li cas los xij, Tebchaws Meskas muaj kev vam khom ntau ntawm kev xa khoom rau cov khoom tseem ceeb no.
Kev sib raug zoo ntawm neodymium hlau boron hlau nplaum thiab motors
Neodymium hlau boron hlau nplaum yog siv nyob rau hauv cov hlau nplaum tas mus li motors.Cov hlau nplaum tas mus li yog: cov hlau nplaum ruaj khov DC lub cev muaj zog, cov hlau nplaum ruaj khov AC lub cev muaj zog, thiab cov hlau nplaum ruaj khov DC motors tau muab faib ua txhuam DC motors, brushless motors, thiab stepping motors.Cov hlau nplaum ruaj khov AC motors tau muab faib ua cov hlau nplaum ruaj khov, cov hlau nplaum ruaj khov servo motors, thiab lwm yam.
Qhov zoo ntawm neodymium hlau boron hlau nplaum
Vim yog cov khoom sib nqus zoo heev ntawm cov khoom siv hlau nplaum neodymium, cov hlau nplaum ruaj khov tuaj yeem tsim tsis muaj zog ntxiv tom qab magnetization.Kev siv lub ntiaj teb tsis tshua muaj zog hlau nplaum lub cev muaj zog es tsis txhob siv cov khoom siv hluav taws xob tsis yog tsuas yog ua haujlwm siab, tab sis kuj yooj yim hauv cov qauv, txhim khu kev qha hauv kev ua haujlwm, me me thiab lub teeb hauv qhov hnyav.Nws tsis tuaj yeem ua tiav qhov kev ua tau zoo (xws li kev ua haujlwm siab, ultra-siab ceev, ultra-siab teb ceev) uas tsoos hluav taws xob excitation motors tsis tuaj yeem sib xws, tab sis kuj tuaj yeem ua tau raws li cov kev xav tau tshwj xeeb ntawm cov motors tshwj xeeb xws li elevator traction. motors thiab tsheb motors.Kev sib xyaw ua ke ntawm lub ntiaj teb tsis tshua muaj cov hlau nplaum ruaj khov motors nrog lub zog hluav taws xob tshuab hluav taws xob thiab microcomputer tswj thev naus laus zis txhim kho kev ua tau zoo ntawm cov hlau nplaum ruaj khov rotor thiab kev sib kis mus rau qib tshiab.Yog li ntawd, kev txhim kho kev ua tau zoo thiab qib ntawm kev txhawb nqa cov cuab yeej siv yog ib qho tseem ceeb ntawm kev txhim kho kev lag luam tsheb los kho cov qauv kev lag luam.
Tuam Tshoj yog lub teb chaws muaj peev xwm ntau lawm ntawm neodymium hlau nplaum.Raws li cov ntaub ntawv, tag nrho lub ntiaj teb no zus tau tej cov neodymium hlau nplaum nyob rau hauv 2019 yog hais txog 170,000 tons, ntawm uas Tuam Tshoj tus zus tau tej cov neodymium hlau boron yog hais txog 150,000 tons, accounting rau txog 90%.
Tuam Tshoj yog lub ntiaj teb coob tsim khoom thiab exporter ntawm tsawg ntiaj teb.Ib qho tariffs ntxiv los ntawm Tebchaws Meskas kuj yuav tsum tau xa los ntawm Tuam Tshoj.Yog li ntawd, US 232 kev tshawb nrhiav yuav tsis muaj kev cuam tshuam rau Tuam Tshoj txoj kev lag luam tshuab hluav taws xob.
