Grafite y’ubukorikori ni polycrystalline isa na crystallography. Hariho ubwoko bwinshi bwa grafite y’ubukorikori n’uburyo butandukanye bwo kuyikora.
Muri rusange, ibikoresho byose bya grafiti byabonetse nyuma yo guhindura ibintu bikomoka ku binyabuzima no guhindura imiterere y’ibintu ku bushyuhe bwinshi bishobora kwitwa grafiti y’ubukorano, nka fibre ya karuboni (grafiti), karuboni ya pyrolytic (grafiti), grafiti y’ifuro, nibindi.
Mu buryo buto, grafiti y'ubukorano ikunze kuvuga ibikoresho bikomeye, nka electrode ya grafiti, grafiti ya isostatic, ikorwa hakoreshejwe uburyo bwo gukusanya, kuvanga, gushushanya, karubone (bizwi nka roasting mu nganda) na grafiti, hamwe n'umwanda muke w'ibikoresho fatizo by'amakara (petroleum coke, asphalt coke, nibindi) nk'ubwoko bwose, icyuma cy'amakara nk'icyuma gifunga.
Hari ubwoko bwinshi bwa grafiti y’ubukorano, harimo ifu, fibre na block, mu gihe ubusobanuro buto bwa grafiti y’ubukorano busanzwe ari block, igomba gutunganywa mu buryo runaka iyo ikoreshejwe. Ishobora gufatwa nk'ubwoko bw'ibikoresho byinshi, harimo graphite phase yahinduwe n'uduce twa karuboni nka peteroli coke cyangwa asphalt coke, graphite phase yahinduwe n'icyuma gifunga amakara gitwikiriye uduce, ubwiyongere bw'uduce cyangwa imyenge ikorwa n'icyuma gifunga amakara nyuma yo kuvura ubushyuhe, nibindi. Muri rusange, uko ubushyuhe burushaho kwiyongera, niko urwego rwa grafiti rurushaho kwiyongera. Umusaruro wa grafiti y’ubukorano mu nganda, urwego rwa grafiti ubusanzwe ruba ruri munsi ya 90%.
Ugereranyije na grafiti karemano, grafiti y’ubukorikori ifite ubushobozi buke bwo kohereza ubushyuhe n’amashanyarazi, ubushyuhe n’ubukonje, ariko grafiti y’ubukorikori nayo ifite ubushobozi bwo kwangirika neza, idatwarwa n’ingufu kandi ifite ubushobozi buke bwo kwinjira kurusha grafiti karemano.
Ibikoresho fatizo byo gukora grafiti y’ubukorano birimo peteroli, isantele coke, asphalt coke, coal pitch, microspheres za karuboni, nibindi. Ibicuruzwa byayo birimo electrode ya grafiti, anode yatetse mbere, grafiti ya isostatic, grafiti ifite ubuziranenge bwinshi, grafiti ya nyukireya, umuyoboro w’ubushyuhe n’ibindi.
Uburyo grafiti y'ubukorano ikoreshwa mu gushushanya ibicuruzwa bigaragarira ahanini muri ibi bikurikira:
1. Electrode ya grafiti: Ikoresheje coke ya peteroli na coke y'inzoga nk'ibikoresho fatizo hamwe n'icyuma gifunga amakara, electrode ya grafiti ikorwa hakoreshejwe calcination, batching, vange, pressing, casting, graptitization na machining. Ikoreshwa cyane mu byuma bikoresha amashanyarazi, silicone y'inganda, fosforufe y'umuhondo n'ibindi bikoresho binyuze mu kurekura ingufu z'amashanyarazi mu buryo bwa arc kugira ngo zishyushye kandi zishongeshe umuriro.
2. Anode itekeshejwe mbere: ikozwe muri peteroli nk'ibikoresho fatizo n'amakara nk'igikoresho cyo gufunga binyuze mu gukaranga, gukurura, kuvanga, gukanda, gukaranga, guteranya, gukoresha graphitization no gutunganya, muri rusange ikoreshwa nk'inode iyobora ibikoresho bya aluminiyumu.
3. Impeta yo gufunga: ibikoresho byo gutwara ibintu byangiza, grafiti y'ubukorano ikoreshwa cyane ikozwe mu mpeta za piston, impeta zo gufunga n'impeta zo gufunga, bikora nta mavuta yo kongeramo.
4. Ihindura ubushyuhe, ubwoko bw'urufunguzo: grafiti y'ubukorano ifite imiterere yo kudatwarwa n'ingufu, ubushobozi bwo gutwara ubushyuhe bwiza no kutagira aho biborohera. Ikoreshwa cyane mu nganda z'ibinyabutabire mu gukora ihindura ubushyuhe, ikigega cy'ingufu, ihindura imiterere y'ibintu, ihindura imiterere y'ibintu n'ibindi bikoresho.
5. Graphite yihariye: ifite peteroli ya coke nziza cyane nk'ibikoresho fatizo, ibara ry'amakara cyangwa resin y'ubukorikori nk'icyuma gifunga, binyuze mu gutegura ibikoresho fatizo, kubivanga, kubivanga, kubikanda, kubisya, kubivanga, kubiteka kenshi, kubinjiramo kenshi, kubitunganya no kubitunganya, kubitunganya no kubikora, muri rusange harimo graphite isostatic, graphite nuclear, graphite high pure, ikoreshwa mu by'ikirere, ibikoresho by'ikoranabuhanga, inganda za nuclear.
