Mavuto ena ndi njira yotukula msika wa graphite powder

Zotsatira zagraphiteku China nthawi zonse wakhala wapamwamba kwambiri padziko lapansi. Mu 2020, China idzatulutsa matani 650,000 a graphite zachilengedwe, zomwe zimawerengera 62% ya dziko lonse lapansi. Koma mafakitale a ufa wa graphite aku China akukumananso ndi mavuto. Furuite graphite yotsatirayi idzakudziwitsani mwatsatanetsatane:

Choyamba ndi chakuti mabizinesi ambiri opangira migodi ndi kukonza ma graphite ku China ali mu "zofooka zazing'ono zobalalika", ndi chitukuko chosalongosoka ndi chitukuko chodyera, kuwononga kwambiri chuma chamchere ndi kuchepa kwa ntchito. Vuto lachiwiri ndilakuti zinthu zachilengedwe zaku China za graphite ndizomwe zimakhala zoyambira kwambiri, ndipo mtengo wowonjezera wa zinthu za graphite ndi wochepa, ndipo zogulitsa zapamwamba zimadalira kwambiri zogulitsa kunja. Chachitatu ndi kunenepa kwambiri kwa zovuta zachilengedwe, ndipo kupanga ufa wa graphite kwalimbikitsidwa ndi kulamulira chilengedwe. The migodi, kuchapa ndi kuyeretsa njira zachilengedwe graphite ufa n'zosavuta kutulutsa fumbi, kuwononga zomera ndi kuipitsa nthaka ndi madzi, pamene kumbuyokupanganjira zamabizinesi a graphite ku China zimabweretsa zovuta zoteteza chilengedwe. Chachinayi, kupanikizika kwa ndalama zogwirira ntchito, migodi ya miyala ya ku China ndi ntchito yogwira ntchito, ndipo ndalama zogwirira ntchito zimakhala zoposa 10% za ndalama zonse zogwirira ntchito. M'zaka zaposachedwa, mtengo wantchito ku China wakwera kwambiri. Chachisanu, mtengo wamagetsi ukuchulukirachulukira osapiririka kwa mabizinesi a graphite.
Graphite ufakupanga ndi bizinesi yowononga kwambiri mphamvu, ndipo mtengo wamagetsi umakhala pafupifupi 1/4. Ndi kukwera kwa magalimoto amagetsi atsopano, zida za anode zamabatire a lithiamu zakhala njira yofunika kwambiri yogwiritsira ntchito graphite. Mabizinesi akuluakulu am'nyumba ambiri adayikanso ndalama pantchito zozama za flake graphite, ndipo ma flake graphite apanga zinthu zambiri zamtengo wapatali; Panthawi imodzimodziyo, kuphatikizidwa kwa chuma cha m'nyumba kukukulirakuliranso, ndipo chuma chapamwamba kwambiri cha mafakitale a graphite chidzapendekeranso ku makampani opanga zazikulu ndi apakatikati; Kuwonjezeka kwakukulu kwa kufunikira kwa mafakitale a ufa wa graphite kudzapititsa patsogolo kukula kwa katundu wa graphite, komanso kuchititsanso kukonzanso nyumba.chithunzi cha graphitemsika.
