Ingano ya coke ni ubwoko bwiza cyane bwakozwe mu bikoresho bya karuboni. Isura yayo ni nk'ikintu gifite imyenge gifite ibara ry'umweru n'icyuma. Imiterere yayo ifite imiterere igaragara, ifite imyobo minini ariko mike kandi ifite imiterere y'uruziga. Ni ibikoresho fatizo byo gukora ibintu bya karuboni byo mu rwego rwo hejuru nka electrode ifite ingufu nyinshi cyane, ibikoresho byihariye bya karuboni, fibre ya karuboni n'ibindi bikoresho byayo bivanze.
Dukurikije ibikoresho bitandukanye bikoreshwa mu gukora, ifu ya needle coke ishobora kugabanywamo ubwoko bubiri bwa needle coke mu mavuta n'amakara. Ifu ya needle coke ikorwa mu bisigazwa bya peteroli nk'ibikoresho fatizo ni ifu ya needle coke mu mavuta. Ifu ya needle coke ikoreshwa mu gupima amakara ikorwa mu ifu ya kaburimbo y'amakara kandi igice cyayo cyitwa ifu ya needle coke mu gupima amakara.
Ibipimo bigira ingaruka ku bwiza bwa needle coke birimo ubucucike nyakuri, ingano ya sulfur, ingano ya azote, ingano ihindagurika, ingano y'ivu, ingano y'ubushyuhe, ingano y'amashanyarazi, ingano y'ingufu zihindagurika, n'ibindi. Bitewe n'ibipimo bitandukanye by'ibipimo, needle coke ishobora kugabanywamo ibice bibiri: super grade (urwego rw'ikirenga), urwego rwa mbere n'urwego rwa kabiri.
Itandukaniro mu mikorere hagati y’ibipimo by’amakara bya needle coke n’ibipimo by’amavuta bya needle coke rikubiyemo ingingo zikurikira.
1. Mu bihe bimwe, electrode ya grafiti ikozwe muri peteroli ikoze muri peteroli iraboroshye kuyikora kurusha ikoze muri peteroli ikoze muri peteroli.
2. Nyuma yo gukora ibikoresho bya grafiti, ibikoresho bya grafiti bya serivise y'amavuta bifite ubucucike n'imbaraga biri hejuru gato kuruta ibya serivise y'amakara, ibyo bikaba biterwa no kwaguka kwa serivise y'amakara mu gihe cyo gukoresha grafiti.
3. Mu ikoreshwa ryihariye rya electrode ya grafiti, ibikoresho bya grafiti bifite inshinge za koke y'amavuta bifite igipimo cyo kwaguka k'ubushyuhe kiri hasi.
4. Ku bijyanye n'ibipimo bya electrode ya grafiti n'iya shimi, ubushobozi bwihariye bwo guhangana n'ibicuruzwa bya grafiti bya serivise ya peteroli ni hejuru gato y'ibicuruzwa bya serivise ya coke y'amakara.
5. Icy'ingenzi cyane ni uko coke yo gupima amakara yaguka mu gihe cyo gupima ubushyuhe bwinshi, iyo ubushyuhe bugeze kuri 1500-2000 ℃, bityo umuvuduko wo kuzamuka k'ubushyuhe ugomba kugenzurwa neza, ntabwo ari ugushyushya vuba, ni byiza kudakoresha uburyo bwo gukora graphitization, coke yo gupima amakara yaguka wongeyeho inyongera kugira ngo ugenzure kwaguka kwayo, igipimo cyo kwaguka gishobora kugabanuka. Ariko biragoye cyane kugera kuri coke yo gupima amavuta.
6. Sisitemu y'amavuta ya calcium ifite ingano ntoya ya coke n'ingano ntoya y'ibinyampeke, mu gihe urushinge rwo gupima amakara rufite ingano ntoya ya coke n'ingano nini y'ibinyampeke (35-40 mm), bishobora kuzuza ibisabwa ku ngano y'ibinyampeke, ariko bikagorana ku mukoresha gusya.
7. Nk’uko ikigo cy’ubutasi bw’ibikomoka kuri peteroli mu Buyapani kibitangaza, bifatwa nk’aho imiterere ya peteroli yoroshye kurusha iya peteroli yo mu bwoko bwa coal, bityo biroroshye kuyigenzura mu gihe cyo kuyicukura.
Ukurikije uko byavuzwe haruguru, imashini ya sintele coke ifite ibintu bine biri hasi: imbaraga nke, imbaraga nke, CTE nke, ubushobozi buke bwo kurwanya, bibiri bya mbere bifite graphite nke, bibiri bya nyuma bifite graphite nke ni byiza. Muri rusange, imikorere ya sintele coke ni myiza kurusha iya sintele coke, kandi ikoreshwa ni rinini.
Kugeza ubu, electrode ya grafiti niyo soko nyamukuru ry’ibikenewe cyane bya needle coke, ingana na 60% by’ikoreshwa ryose rya needle coke, kandi ibigo by’amashanyarazi bifite icyifuzo cyumvikana cy’ubwiza bwa needle coke, nta buziranenge bwihariye bikeneye. Ibikoresho bya anode bya bateri ya Lithium ion bifite icyifuzo gitandukanye cya needle coke, isoko ryo mu rwego rwo hejuru rya digitale rikunda coke itetse amavuta, isoko rya bateri y’amashanyarazi rishingiye cyane kuri coke mbisi ihendutse kandi ihendutse.
Umusaruro wa needle coke ufite urugero runaka rwa tekiniki, bityo hari ibigo bike byo mu gihugu. Kuri ubu, inganda zikora peteroli zo mu gihugu zirimo Shandong Jingyang, Shandong Yida, Jinzhou Petrochemical, Shandong Lianhua, Bora Biological, Weifang Fumei New Energy, Shandong Yiwei, Sinopec Jinling Petrochemical, Maoming Petrochemical, nibindi. Abakora cyane ikoreshwa rya needle coke ni Baowu Carbon Material, Baotailong Technology, Anshan Kaitan, Angang Chemical, Fang Daxi Kemo, Shanxi Hongte, Henan Kaitan, Xuyang Group, Zaozhuang Zhenxing, Ningxia Baichuan, Tangshan Dongri New Energy, Taiyuan Shengxu, nibindi.
