Inkqubo Entsha yokuRecycling iimagnethi

Iingcali zenzululwazi kwilebhu yophando ye-Ames ziye zavelisa indlela yokugaya kunye nokuphinda kusetyenziswe imagnethi ye-neodymium efunyenwe njengenxalenye yeekhomputha ezilahliweyo. Inkqubo yaphuhliswa kwiSebe le-US le-Critical Materials Institute (CMI) yeSebe le-US eligxile kwiiteknoloji ezisebenzisa kakuhle izinto kunye nokuphelisa imfuno yezinto ezixhomekeke ekuphazamiseni ukubonelela.
Ukukhutshwa kweendaba ezipapashwe yi-Ames Laboratory ichaza inkqubo ejika i-hard disk drive (i-HDD) elahliweyo imagnethi kwizinto ezintsha zemagnethi ngamanyathelo ambalwa. Le ndlela intsha yokurisayikilisha ijongana nemiba yezoqoqosho neyendalo ehlala ithintela inkunkuma ye-e-migodini kwizinto ezixabisekileyo.
NgokukaRyan Ott, isazinzulu kwi-Ames Laboratory kunye nelungu leqela lophando lwe-CMI, "ngobuninzi obukhulayo bezinto zombane ezilahliweyo kwihlabathi jikelele, kube sengqiqweni ukugxila kowona mthombo ubalulekileyo wemagnethi enqabileyo emhlabeni kulo mjelo wenkunkuma. -ihard disk drives, ezinomthombo we-scrap ophakathi."
Iingcali zenzululwazi kunye nosomashishini baye bajonga iindlela ezahlukeneyo zokukhupha izinto ezinqabileyo zomhlaba kwi-e-waste, kwaye abanye babonise isithembiso sokuqala. Nangona kunjalo, "ezinye zenza iimveliso ezingafunwayo kwaye izinto ezifunyenweyo zisafuna ukufakwa kwisicelo esitsha," utshilo u-Ott. Ngokususa amanyathelo amaninzi okusebenza kangangoko kunokwenzeka, indlela yelabhoratri ye-Ames itshintsha ngokuthe ngqo ngakumbi ukusuka kwimagnethi elahliweyo ukuya kwimveliso yokugqibela-umazibuthe omtsha.

Inkqubo yokubuyiselwa kweMagnet ichaziwe

Iimagnethi ezilahliweyo zeHDD ziyaqokelelwa
Naziphi na iingubo zokukhusela ziyasuswa
Iimagnethi zityunyuzwa zibe ngumgubo
Isitshizi sePlasma sisetyenziselwa ukufaka imathiriyeli engumgubo wemagnethi kwisubstrate
Iingubo zinokwahluka ukusuka kwi-½ ukuya kwi-1 mm ubukhulu
Iipropathi zeemveliso zemagnethi zokuphela ziyakwazi ukwenziwa ngokuxhomekeke kulawulo lokuqhuba
Ngelixa imathiriyeli entsha yamagnetic ingenako ukugcina iipropathi zemagnethi ezikhethekileyo zemathiriyeli yokuqala, inokuthi izalise iimfuno zentengiso kukhetho lwezoqoqosho apho ukusebenza kwemagnethi yamandla aphezulu anqabileyo emhlabeni kungafuneki, kodwa imagnethi yokusebenza esezantsi efana neeferrites ayonelanga. .
“Le nkalo yokunciphisa inkunkuma yale nkqubo iphindwe kabini; asisisebenzisi nje iimagnethi zokuphela kobomi kuphela,” utshilo u-Ott. “Sikwanciphisa umyinge wokwenziwa kwenkunkuma eveliswayo ekwenzeni iimagnethi ezincinci nezincinci zejiyometri ngezinto ezinkulu.
