Grafiti ishobora kwaguka ikorwa n'ibikorwa bibiri

Graphite ishobora kwaguka ikorwa hakoreshejwe inzira ebyiri: imiti n'amashanyarazi. Izi nzira zombi ziratandukanye usibye inzira yo gukaraba, gukuraho aside, koza amazi, kubura amazi, kumisha n'izindi nzira ni zimwe. Ubwiza bw'ibicuruzwa by'inganda nyinshi zikoresha uburyo bwa chimique bushobora kugera ku gipimo cyagenwe muri GB10688-89 "graphite ishobora kwaguka", kandi bugahura n'ibisabwa mu gukora impapuro za graphite zihinduka cyane n'ibipimo by'ibicuruzwa byoherezwa mu mahanga.

Ariko gukora ibintu byihariye bisabwa kugira ngo habeho ihindagurika rito (≤10%), ingano nto ya sulfure (≤2%) y’ibicuruzwa biragoye, inzira yo kubitunganya ntirarenga. Gushimangira imicungire ya tekiniki, kwiga witonze inzira yo guhuza, kumenya isano iri hagati y’ibipimo by’imikorere n’imikorere y’ibicuruzwa, no gukora graphite nziza ishobora kwaguka ni ingenzi mu kunoza ubwiza bw’ibicuruzwa bikurikira. Incamake ya graphite ya Qingdao Furuite: uburyo bwa electrochemical budafite izindi oxydants, graphite karemano ya flake na anode yunganira hamwe bigizwe n’icyumba cya anode cyinjijwe muri electrolyte ya aside sulfurike, binyuze mu muyoboro w’amashanyarazi cyangwa umuyoboro w’amashanyarazi, oxidation nyuma y’igihe runaka cyo kuyikuramo, nyuma yo kumesa no kuyumisha ni graphite ishobora kwaguka. Ikintu gikomeye kiranga ubu buryo ni uko urwego rw’ihinduka rya graphite n’umubare w’imikorere y’ibicuruzwa bishobora kugenzurwa hakoreshejwe guhindura ibipimo by’amashanyarazi n’igihe cyo guhuza, hamwe n’umwanda muto, igiciro gito, ubwiza buhamye n’imikorere myiza. Ni ngombwa gukemura ikibazo cyo kuvanga, kunoza imikorere no kugabanya ikoreshwa ry’ingufu mu nzira yo guhuza.

Nyuma yo gukuraho aside muri izi nzira ebyiri zavuzwe haruguru, igipimo cy’uburemere bw’amazi aside sulfuriki anyuramo kandi agakomeza kwinjiza graphite interlamellar compounds kiracyari hafi 1:1, ikoreshwa ry’ibintu bihuza ibyuma ni rinini, kandi amazi yo kumesa n’amazi y’imyanda akoreshwa ari menshi. Kandi abakora inganda benshi ntibakemuye ikibazo cyo gutunganya amazi yanduye, mu gihe amazi yavuye mu buryo bw’umwimerere, ihumana ry’ibidukikije ni ribi cyane, bizabangamira iterambere ry’inganda.
