Inqubo Entsha Yokugaywa Kabusha Kazibuthe

Ososayensi endaweni yocwaningo yase-Ames benze indlela yokugaya futhi basebenzise kabusha izibuthe ze-neodymium ezitholakala njengengxenye yamakhompyutha alahliwe. Inqubo yathuthukiswa ku-Critical Materials Institute (CMI) yoMnyango Wezamandla wase-US egxile kubuchwepheshe obusebenzisa kangcono izinto ezisetshenziswayo futhi eqeda isidingo sezinto ezibonakalayo ezingaphazanyiswa ukunikezwa.
Ukukhishwa kwezindaba okushicilelwe i-Ames Laboratory ichaza inqubo eshintsha omagnethi balahliwe babenze izinto zikazibuthe ezintsha ngezinyathelo ezimbalwa. Le nqubo emisha yokugaywa kabusha ibhekana nezindaba zezomnotho nezemvelo ezivame ukuvimbela imfucumfucu ye-e yezimayini ngezinto ezibalulekile.
NgokukaRyan Ott, usosayensi e-Ames Laboratory futhi oyilungu lethimba labacwaningi be-CMI, “ngenani elikhula njalo lama-elekthronikhi alahliwe emhlabeni wonke, kunengqondo ukugxila emthonjeni otholakala yonke indawo wezibuthe zomhlaba eziyivelakancane kulowo mfudlana. -ama-hard disk drive, anomthombo we-scrap ophakathi nendawo."
Ososayensi nosomabhizinisi bebelokhu bebheka izindlela ezahlukahlukene zokukhipha izakhi zomhlaba ezingavamile ku-e-waste, futhi abanye baye babonisa isithembiso sokuqala. Kodwa-ke, "ezinye zidala imikhiqizo engafunwa futhi izinto ezitholiwe zisadinga ukufakwa ohlelweni olusha," kusho u-Ott. Ngokususa izinyathelo eziningi zokucubungula ngangokunokwenzeka, indlela yaselabhorethri ye-Ames ishintsha ngokuqondile kakhulu isuka kuzibuthe elahliwe iye kumkhiqizo wokugcina - uzibuthe omusha.

Kuchazwe Inqubo Yokubuyiselwa Kwezibuthe

Ozibuthe be-HDD abalahliwe bayaqoqwa
Noma yiziphi izigqoko zokuzivikela ziyasuswa
Izibuthe zichotshozwa zibe yimpushana
I-Plasma spray isetshenziselwa ukufaka into eyimpuphu kazibuthe ku-substrate
Izembatho zingahlukahluka kusuka ku-½ kuye ku-1 mm ubukhulu
Izici zokuphela kwemikhiqizo kazibuthe zingenziwa ngendlela oyifisayo kuye ngezilawuli zokucubungula
Nakuba into entsha kazibuthe ingakwazi ukugcina izici ezivelele zikazibuthe zento yokuqala, igcwalisa izidingo zemakethe ngokukhetha ukonga lapho ukusebenza kukazibuthe wamandla amakhulu ayivelakancane kungadingeki, kodwa omazibuthe abasebenza kancane njengama-ferrites abanele. .
“Le ngxenye yokunciphisa udoti yale nqubo iphindwe kabili; asigcini ngokuphinda sisebenzise omazibuthe bokuphela kwempilo,” kusho u-Ott. “Sinciphisa nenani lodoti okhiqizwayo ekwenzeni omazibuthe bejiyomethri abancane nabancane ngezinto ezinkulu eziyinqwaba.
