New Process kuti Recycling Magnets

Masayendisiti kuAmes research lab akagadzira nzira yekukuya nekudzorera neodymium magineti anowanikwa sechikamu chemakomputa akaraswa. Maitiro aya akagadzirwa kuUS department reEnergy's Critical Materials Institute (CMI) iyo inotarisa kune matekinoroji anoshandisa zvirinani zvinhu uye kubvisa kudiwa kwezvinhu zvinogona kukanganiswa kwekupa.
Nhau yakaburitswa neAmes Laboratory inotsanangura maitiro anoshandura akaraswa hard disk drive (HDD) magineti kuita zvinhu zvitsva zvemagineti mumatanho mashoma. Iyi nzira itsva yekudzokorodza inogadzirisa nyaya dzehupfumi uye dzezvakatipoteredza dzinowanzorambidza migodhi e-marara yezvinhu zvakakosha.
Sekureva kwaRyan Ott, musayendisiti paAmes Laboratory uye nhengo yeCMI timu yekutsvagisa, "nehuwandu hunoramba huchiwedzera hwemagetsi akaraswa pasi rose, zvine musoro kutarisa kune yakanyanya kuwanikwa sosi yemagineti anokosha epasi murukova rwemarara. -madhisiki edhisiki, ane nzvimbo yepakati pezvikara.
Masayendisiti nevashambadziri vanga vachitarisa nzira dzakasiyana dzekuburitsa zvisingawanzo-pasi zvinhu kubva mu-e-marara, uye vamwe vakaratidza vimbiso yekutanga. Nekudaro, "zvimwe zvinogadzira zvisingadiwe-zvigadzirwa uye izvo zvakadzoserwa zvichiri kuda kuiswa muchirongwa chitsva," akadaro Ott. Nekubvisa matanho akawanda ekugadzirisa sezvinobvira, nzira yerabhoritari yeAmes inoshandura zvakanyanya zvakananga kubva kune yakaraswa magineti kuenda kune yekupedzisira chigadzirwa - magineti nyowani.

Iyo Magnet Reclamation Process Inotsanangurwa

Akachekwa HDD magineti anounganidzwa
Chero zvipfeko zvekudzivirira zvinobviswa
Magnets anopwanyika kuita upfu
Plasma spray inoshandiswa kuisa hupfu hwemagineti pane substrate
Coatings anogona kusiana kubva ½ kusvika 1 mm gobvu
Zvivakwa zvekupedzisira magineti zvigadzirwa zvinogoneka zvinoenderana nekugadzirisa zvinodzora
Nepo iyo nyowani yemagineti isingakwanise kuchengetedza yakasarudzika magineti echinhu chepakutanga, inogona kuzadza misika inodiwa yesarudzo yehupfumi uko kuita kwesimba repamusoro-simba remagineti repasi risingadiwi, asi magineti epasi ekuita senge ferrite haana kukwana. .
“Iyi nzira yekudzikisa marara pakuita uku kwakapetwa kaviri; hatisi kungoshandisazve magineti ekupera kwehupenyu,” akadaro Ott. “Tiri kuderedza zvakare huwandu hwemarara anogadzirwa mukugadzira magineti matete uye madiki ejiometri kubva mumidziyo mikuru.
