Imiterere mito (imiterere ya kristale) ya koka ya peteroli ya grafiti imeze ite?

I. Ibiranga imiterere ya kristu

Imiterere y’ibice: Imiterere ya kristu ya graphitized petroleum coke igizwe n’urusobe rw’ibice bya atome za karuboni zifite impande esheshatu. Izi mpande zigizwe n’urusobe rw’ibice, zigakora imiterere isanzwe y’ibice. Ibice bihuzwa n’imbaraga za van der Waals zidakomeye, zitanga graphite amavuta n’ubushyuhe.
Ibikoresho bya Lattice: Nyuma yo kuvugururwa hakoreshejwe graphitization, ibikoresho bya lattice (a₀ na c₀) bya peteroli coke bigera kuri graphite karemano, bigaragaza imiterere yabyo isa cyane. Iyi miterere ituma peteroli coke ifite graphit igaragaza imikorere myiza y'amashanyarazi n'ubushyuhe.
Ibipimo bya microcrystalline: Hakoreshejwe diffraction ya X-ray, ibipimo nka interlayer spacing (d₀₀₂), interuro layer diameter (Lₐ), na stacking height (Lc) bya microcrystals muri grafitited petroleum coke birashobora kubarwa. Ibi bipimo bigaragaza ingano n'imiterere ya microcrystals kandi bikaba ibipimo by'ingenzi byo gusuzuma urwego rwa grafitisation.

II. Ingaruka z'Inzira yo Gushushanya Ishusho

Impinduka kuva kuri Amorphous kugera kuri Crystalline State: Mbere yo gukoresha graphitization, imiterere ya karuboni ya peteroli coke iba idahinduka, irangwa n'imiterere y'ibintu "bidafite aho bihuriye n'igihe kirekire, kandi bikozwe mu buryo bugufi". Binyuze mu kuvura graphitization (ubusanzwe bikorwa ku bushyuhe bwinshi kuva kuri 2500°C kugeza kuri 3000°C), karuboni idahinduka buhoro buhoro ihinduka imiterere ya kristalo ya grafiti ifite imiterere itatu.
Ubwiyongere bw'ingano ya Microcrystallite: Mu gihe cyo gukoresha graphitization, ubugari busanzwe (Lc) n'ubugari (Lₐ) bw'uduce twa carbone lattice flakes biriyongera, mu gihe intera iri hagati y'uduce (d) igabanuka. Ibi bituma ingano ya microcrystallite yiyongera ndetse n'imiterere ya kristu irushaho kuba nziza.
Kugabanuka k'ubudahangarwa: Uko urugero rwa graphitization rwiyongera, ubudahangarwa bwa graphitized petroleum coke bugabanuka cyane. Ibi biterwa nuko, mu gihe cya graphitization, imiterere ya atome za karuboni irushaho kuba myiza, bigatuma electron zigenda neza mu buryo bwihuse mu miterere y'ibice, bityo byongera ubudahangarwa bw'amashanyarazi.

III. Isano iri hagati y'imiterere mito n'imiterere

Ubushobozi bwo gutwara amashanyarazi: Imiterere ya kristu ya graphitized petroleum coke ituma electron zigenda neza mu byiciro by’amashanyarazi, bigatuma habaho ubushobozi bwo gutwara amashanyarazi bwiza. Ubu buryo butuma graphitized petroleum coke ikoreshwa cyane mu bice nka electrode equipment n’ibindi bikoresho bitwara amashanyarazi.
Uburyo bwo gutwara ubushyuhe: Bitewe n'imbaraga za van der Waals zihuza ibice, ubushyuhe bushobora kwimurirwa vuba mu bice by'ibice. Kubera iyo mpamvu, koke ya peteroli ifite grafiti igaragaza uburyo bwiza bwo gutwara ubushyuhe, bigatuma ikoreshwa mu gukora ibikoresho bikwirakwiza ubushyuhe n'ibindi bikorwa.
Imiterere ya Mechanical: Imiterere ya kristu ya graphitized petroleum coke iyiha imbaraga runaka za mekanike. Ariko, ugereranije n'ibikoresho by'icyuma, imiterere yayo y'ibice bito ituma habaho guhuza kw'ibice bito, bigatuma imbaraga zo gukanda no gukanda zigabanuka. Iyi miterere y'imikorere ituma graphitized petroleum coke iba nziza mu gihe ikeneye kwihanganira imbaraga zimwe na zimwe ariko idasaba imbaraga nyinshi.
