Koke ya Peteroli ifite Graphitized: "Umwami" mu bacuruza kaburimbo

Koke ya peteroli ifite grafiti ifatwa nk' "umwami" mu bintu bitera carburizing bitewe ahanini n'uko isukuye cyane, kristali nyinshi, umuvuduko mwiza wo kwinjiza, no kudahungabana, igaragaza agaciro kadasimburwa mu nzego nyinshi nko mu byuma, gukora ibicuruzwa bya grafiti, no mu nganda za gisirikare. Isesengura rikurikira rikorwa mu byiciro bitatu: imiterere y'ingenzi, ibyiza byo gukora, n'imiterere y'ikoreshwa ryayo.

I. Ibiranga by'ingenzi: "Ingirabuzimafatizo z'ubwami" za Graphitized Petroleum Coke

Ubwiza bwinshi n'umwanda muke

Koke ya peteroli ya grafitize ikorerwa ubushyuhe bwinshi ku bushyuhe bwa 2200 - 2600℃, ibi bikaba bikuraho imyanda myinshi nka sulfur, azote, n'ivu. Ingano yayo ya karuboni idahinduka iri hejuru ya 80% - 92%, aho ingano ya sulfur iri hasi ya ≤0.1% naho ingano ya azote iri hasi ya ≤0.5%. Iyi miterere yo kuba isukuye cyane ituma idashyiramo ibintu byangiza mu gihe cyo gukaraba, bigatuma ubwiza bw'icyuma burushaho kwiyongera. Urugero, mu gukora ibyuma, ingano nto ya sulfur ishobora kugabanya "ubushyuhe bukabije" no kongera ubushobozi bwo kudakora no kudakora neza kw'icyuma.

Ubushyuhe bwinshi n'ubudahangarwa

Uburyo bwo gushyiramo graphitization bushyira atome za karuboni mu miterere isanzwe ya graphite, bigatuma habaho imiterere ya crystalline nyinshi. Iyi miterere irahamye cyane iyo hari ubushyuhe bwinshi kandi ntishobora kwangirika cyane, bigatuma habaho ingaruka zirambye za carburizing. Mu buryo bunyuranye, peteroli coke idakoreshejwe graphit irashobora kwangirika iyo hari ubushyuhe bwinshi, bigatuma igipimo cyo kwinjiza karuboni kigabanuka.

Imiterere y'imyenge n'imikorere myinshi

Koke ya peteroli ifite imyenge ifite ubuso bunini bwihariye, ituma ishobora gukorana vuba no kubora mu byuma bishonga cyangwa ibyuma bigahinduka urusenda, ibyo bikaba byongera cyane umuvuduko wo kwinjiza karubone. Amakuru y’igerageza agaragaza ko ingaruka zayo zo kwinjiza karubone zingana n’iz’ibintu bikoresha karubone bifite karubone irenga 90%, ariko ifite umuvuduko wo kwinjiza vuba, bishobora kugabanya igihe cyo gushongesha ho 10% - 15%, bigatuma ingufu zibungabungwa kandi zikagabanuka.

II. Ibyiza by'Inzira: Guhindura Ibuye Ikamera Zahabu binyuze mu Gutunganya Graphitization

Gutunganya Imiterere ya Molecular

Uburyo bwo gutunganya imiterere y’ibice bya karuboni bwagura intera iri hagati y’atome za karuboni, bigatuma habaho imiterere ya kristu ifite impande esheshatu ituma ibora neza. Iyi miterere ishobora kurekura atome za karuboni vuba mu byuma bishonga, bigatuma habaho imiterere ya graphite no kunoza imiterere ya graphite y’icyuma gishongeshejwe (nk’uko byongera umubare wa graphite ya spéroidal), bityo bikongera imiterere ya mekanike n’ubushobozi bwo gukora ibyuma bishongeshejwe.

Ingano hagati y'Ikiguzi n'Ingufu

Nubwo gutunganya graphitization bisaba gukoresha ingufu mu bushyuhe bwinshi, igipimo cyayo cyo kwinjiza no kudahungabana bishobora kugabanya ingano y'ibikoresho bya carburizing bikoreshwa (ubusanzwe 20% - 30% munsi y'ibikoresho bya carburizing bikoresha amakara) no kugabanya igihombo cyo kubura umusaruro giterwa no guhindura kenshi ibice bigize ibyuma. Mu gihe kirekire, igiciro rusange kiba gito, kandi gishobora kunoza ireme ry'ibicuruzwa buhoro buhoro.

III. Imiterere y'Ikoreshwa: "Umukinnyi w'Ibintu Byose" kuva ku Bumenyi bw'Ibyuma kugeza ku Ikoranabuhanga Rihanitse

Inganda zikora ibyuma: Ingwate ebyiri zo kunoza ireme rya carburizing no gukoresha neza ibikoresho

• Gukora ibyuma: Mu kongera ingano y'ibyuma bishaje no kugabanya ikoreshwa ry'icyuma cy'ingurube, hamwe na carburizing hakoreshejwe graphitized petroleum coke, ikiguzi cy'icyuma gishobora kugabanukaho 10% - 20%, mu gihe cyongera ubuziranenge n'imiterere y'icyuma.
• Gucana: Binoza imiterere ya grafiti n'urwego rwa nodularity, byongera igihe cyo gukora castings. Urugero, mu gucana moteri ya moteri, gukoresha graphitized petroleum coke bishobora kongera imbaraga zo kudacika intege ku kigero cya 15% - 20%.

Gukora ibikoresho bya Graphite: Ibuye ry'ifatizo ry'ibikoresho byo mu rwego rwo hejuru

Koke ya peteroli ifite grafiti ni igikoresho cy'ingenzi cyo gukora ibice binini bya cathode, electrode za karuboni, electrode zifite grafiti, na pastes za electrode zifite imikorere myiza. Ubuziranenge bwayo bwinshi n'ubuziranenge bwayo bukabije bishobora guhaza ibyifuzo by'amatanura y'inganda akura akagera ku bunini kandi bunini cyane, bikagabanya igihombo cya oxidation ku bushyuhe bwinshi no kongera igihe cyo gukoresha ibikoresho.

Inganda za gisirikare: Umukinnyi ushobora gukora ibikoresho bidashobora gutwarwa n'amasasu

Diyama y'umukara (diyama isanzwe ya polycrystalline) ifatwa nk'igikoresho cy'ibumba cyo mu gihe kizaza cyo kuziba ibisasu bitobora intwaro bitewe n'ubukana bwayo bwinshi (ikurikira diyama na boron nitride) hamwe n'ubucucike bwayo buke (2.52 g / cm³). Coke ya peteroli ya graphitized, binyuze mu gutunganya cyane, ishobora gusimbura igice cya diyama y'umukara mu gukora ibikoresho bihamye bya gisirikare, bigagabanya kwishingikiriza ku bushobozi buke.

Izindi nzego z'inganda: "Ibikoresho by'inyongera rusange" ku bikorwa byambukiranya imipaka

• Inganda zikora imiti: Ikora nk'ikintu kigabanya ubukana, itera umuti ugabanya ubukana, n'ibikoresho birwanya ubukana.
• Inganda z'amashanyarazi: Ikoreshwa mu gukora uburoso bwa karuboni, kunoza imikorere y'amashanyarazi no kudashira.
• Inganda za Bateri: Ikoreshwa mu bikoresho bya electrode kugira ngo yongere ubucucike bw'ingufu n'ubuzima bw'uruziga.
• Inganda z'ubukanishi: Ikora nk'amavuta yo kugabanya igihombo cyo gushwanyagurika.

Umwanzuro: "Inzira y'Umwami" ya Graphitized Petroleum Coke

Koke ya peteroli ifite graphite yashyizeho urugero mu bijyanye n’ibintu bihumanya ikirere hamwe n’imiterere yayo yihariye y’umubiri n’imiti. Ntabwo ikemura gusa ibibazo by’umwanda mwinshi n’umuvuduko muke w’ibintu bikoresha carburite bisanzwe, ahubwo inateza imbere ivugurura ry’ibikoresho mu by’icyuma, ikorwa ry’ibicuruzwa bya grafiti, n’inganda za gisirikare binyuze mu buryo buhanitse kandi buhamye. Kubera ko hari kwiyongera gukenewe mu kubungabunga ingufu, kugabanya imyuka ihumanya ikirere, no gukora ibintu byo mu rwego rwo hejuru, "icyubahiro cy’ubwami" cya koke ya peteroli ifite graphite kizarushaho gukomera, bigatuma iba "diyama y'umukara" y’ingenzi mu kuvugurura inganda.
