Njira Yatsopano Yobwezeretsanso Maginito

Asayansi ku labu yofufuza ya Ames apanga njira yopera ndikubwezeretsanso maginito a neodymium omwe amapezeka ngati gawo la makompyuta otayidwa. Njirayi idapangidwa ku US Department of Energy's Critical Materials Institute (CMI) yomwe imayang'ana kwambiri matekinoloje omwe amagwiritsa ntchito bwino zida ndikuchotsa kufunikira kwa zinthu zomwe zimatha kusokoneza.
Nkhani yofalitsidwa ndi Ames Laboratory ikufotokoza njira yomwe imatembenuza maginito otayidwa a hard disk drive (HDD) kukhala maginito atsopano pamasitepe ochepa. Njira yatsopanoyi yobwezeretsanso imayang'anira zovuta zachuma ndi zachilengedwe zomwe nthawi zambiri zimaletsa migodi ya e-zinyalala pazinthu zamtengo wapatali.
Malinga ndi Ryan Ott, wasayansi ku Ames Laboratory komanso membala wa gulu lofufuza la CMI, "pokhala ndi zida zamagetsi zotayidwa zomwe zikuchulukirachulukira padziko lonse lapansi, zinali zomveka kuyang'ana pa gwero lopezeka paliponse la maginito osowa padziko lapansi mumtsinje wa zinyalalawo. -ma hard disk drive, omwe ali ndi magwero apakati.
Asayansi ndi amalonda akhala akuyang'ana njira zosiyanasiyana zopezera zinthu zapadziko lapansi kuchokera ku e-waste, ndipo ena asonyeza lonjezo loyamba. Komabe, "ena amapanga zinthu zosafunikira ndipo zomwe zidabwezedwa zikufunikabe kuphatikizidwa mu pulogalamu yatsopano," adatero Ott. Pochotsa masitepe ambiri momwe angathere, njira ya labotale ya Ames imasintha mwachindunji kuchokera ku maginito otayidwa kupita ku chinthu chomaliza - maginito atsopano.

The maginito Reclamation ndondomeko anafotokoza

Maginito a HDD ochotsedwa amasonkhanitsidwa
Zovala zilizonse zoteteza zimachotsedwa
Maginito amaphwanyidwa kukhala ufa
Kupopera kwa plasma kumagwiritsidwa ntchito kuyika zinthu zamaginito za ufa pagawo laling'ono
Zovala zimatha kusiyanasiyana kuchokera ½ mpaka 1 mm wakuda
Katundu wa mapeto maginito mankhwala ndi customizable malinga processing amazilamulira
Ngakhale kuti maginito atsopanowa sangathe kusunga mphamvu ya maginito ya chinthu choyambirira, amatha kukwaniritsa zosowa za msika kuti asankhe mwachuma pomwe maginito amphamvu kwambiri sakufunika, koma maginito otsika ngati ma ferrite sali okwanira. .
“Kuchepetsa zinyalala panjira imeneyi kulidi pawiri; Sitikungogwiritsanso ntchito maginito a mapeto a moyo,” anatero Ott. "Tikuchepetsanso kuchuluka kwa zinyalala zomwe zimapangidwa popanga maginito opyapyala komanso ang'onoang'ono a geometry kuchokera kuzinthu zazikulu zambiri.
