Iyo grafite ivuwe muburyo bwa chimique, reaction ya chimique ikorerwa icyarimwe kumpera ya grafite yagutse no hagati ya layer. Niba igishushanyo cyanduye kandi kirimo umwanda, inenge ya lattice na dislokasiyo bizagaragara, bikavamo kwaguka kwakarere ka ruguru no kwiyongera kwimbuga zikora, bizihutisha inkombe. Nubwo ibi ari ingirakamaro mugushinga ibice, bizagira ingaruka kumiterere yagutse ya grafite intercalation. Kandi uruzitiro rwarasenyutse, rutuma uruzitiro rudahungabana kandi rudasanzwe, kuburyo umuvuduko nuburebure bwikwirakwizwa ryimiti kuri interineti hamwe no kubyara ibice byimbitse byuzuzanya bikabangamirwa kandi bigarukira, ibyo bikagira ingaruka no kuzamura urwego rwagutse. Kubwibyo, birasabwa ko ibirimo umwanda wa grafite bigomba kuba mubipimo byagenwe, cyane cyane umwanda wa granulaire ntugomba kubaho, bitabaye ibyo umunzani wa grafite uzacibwa mugihe cyo gukanda, bizagabanya ubwiza bwibikoresho byabumbwe. Ubwanditsi bukurikira bwa Furuite bwerekana ko ubuziranenge bwibikoresho fatizo bigira ingaruka kumiterere ya grafite yagutse:
Ingano yubunini bwa grafite nayo igira uruhare runini mubikorwa bya grafite yagutse. Ingano yubunini ni nini, ubuso bwihariye ni buto, kandi agace kagira uruhare mubikorwa bya chimique ni nto. Ibinyuranye na byo, niba agace ari gato, ubuso bwacyo bwihariye ni bunini, kandi ahantu ho kwitabira imiti ni nini. Duhereye ku isesengura ryingorabahizi yibintu byimiti itera, byanze bikunze ibice binini bizakora umunzani wa grafite, kandi icyuho kiri hagati yacyo kizaba cyimbitse, kuburyo bigoye ko imiti yinjira muri buri cyiciro, kandi birarenze bigoye gukwirakwiza mu cyuho kiri hagati yo gutera ibice byimbitse. Ibi bifite uruhare runini kurwego rwo kwagura grafite. Niba ibice bya grafite ari byiza cyane, ubuso bwihariye buzaba bunini cyane, kandi impande zifatika zizaba ziganje, ibyo bikaba bitajyanye no gushiraho ibice bivangwa. Kubwibyo, ibice bya grafite ntibigomba kuba binini cyane cyangwa bito cyane.
Mubidukikije bimwe, mubusabane hagati yubucucike nubunini bwa grafite yagutse ikozwe muri grafite nubunini butandukanye, uko umuto uciriritse, niko ingaruka nziza yagutse. Nyamara, mubikorwa nyabyo, herekanwa ko ingano yubunini bwa grafite ikoreshwa nibyiza kuva kuri -30 mesh kugeza kuri +100 mesh, ningaruka nziza cyane.
Ingaruka yubunini bwa grafite nayo igaragarira muburyo ingano yingingo yibigize ibigize itagomba kuba yagutse cyane, ni ukuvuga ko itandukaniro rya diameter hagati yikintu kinini n’utuntu duto tutagomba kuba kinini, kandi ingaruka zo gutunganya zizaba byiza niba ingano yubunini igizwe ni imwe. Ibicuruzwa bya Furuite byose bikozwe muri grafite karemano, kandi ubuziranenge burasabwa cyane mubikorwa byo gukora. Ibicuruzwa bya grafite bitunganijwe kandi byakozwe byatoneshejwe nabakiriya bashya kandi bashaje imyaka myinshi, kandi burigihe urahawe ikaze kugisha inama no kugura!
