Ni uruhe ruhare rwa koke ya peteroli ya grafiti mu nganda zitunganya ubutare nka silikoni y'inganda na silikoni karubide?

Uruhare rwa Graphitized Petroleum Coke mu nganda zishongesha Silicone na Silicon Carbide mu nganda zishongesha

I. Uruhare mu gushongesha silicon mu nganda

1. Imikorere y'Umukozi Ugabanya Ishingiro ry'Umusaruro
Coke ya peteroli ifite grafiti ni imwe mu nganda zigabanya karubone mu musaruro wa silikoni mu nganda. Ifite karubone nyinshi (90%-97%) n'imiterere y'ivu nke bituma iba ibikoresho by'ingenzi mu gutanga karubone ikenewe mu gukora ibikorwa. Mu gihe cyo gushongesha itanura ry'amashanyarazi, coke ya peteroli yorohereza guhindura silikoni (SiO₂) muri silikoni y'inganda binyuze mu gukora ibikorwa byo kugabanya karubone. Byongeye kandi, amashanyarazi yayo afasha mu kugenzura ubudahangarwa bw'umuriro w'itanura, kugenzura uburebure bw'amashanyarazi no kunoza imikorere y'itanura ry'amashanyarazi.

2. Kunoza imikorere y'umuriro w'ifuru

• Guhindura uburyo amashanyarazi akoreshwa: Uburyo amashanyarazi akoreshwa muri peteroli ya coke agira ingaruka ku buryo amashanyarazi akoreshwa mu itanura adashobora gushyuha. Mu guhindura ingano yaryo n'ingano y'uduce, ubushobozi bw'ubushyuhe bw'itanura ry'amashanyarazi bushobora kunozwa, bigagabanya ikoreshwa ry'amashanyarazi.
• Kunoza ubushobozi bwo gupima ubushyuhe: Koke y’amavuta ya peteroli ikunda gukora graphiti ku bushyuhe bwinshi, bigatuma habaho igishishwa ku buso bw’itanura. Kugira ngo ibi bigerweho, uduce tw’ibiti cyangwa umukungugu w’ibiti bivangwa kugira ngo byongere ubushobozi bwo guhangana n’umuriro, byongere ubushobozi bwo kwinjira mu itanura, kandi bihamye imikorere.
• Inyongeramusaruro ku bikorwa bya chimique: Koka ya peteroli ifite ubushobozi bwo kugabanya ubukana buke kandi ikunze gukoreshwa hamwe n'amakara ya silikoni cyangwa amakara make kugira ngo ikomeze kugabanya ubukana.

3. Kuringaniza Ubwiza n'Ikiguzi

• Umusaruro wa Silicon yo mu rwego rwo hejuru: Ivu rike rya peteroli coke rituma iba nziza mu gukora silicon yo mu nganda ifite isuku nyinshi. Ariko, sulfur, vanadium, nickel, n'indi myanda igomba kugenzurwa, cyane cyane mu ikorwa rya organosilicon, aho ingano ya peteroli coke igengwa kugira ngo hirindwe uburozi bwa catalyst.
• Ibyiza by'Ubukungu: Ugereranyije n'amakara, peteroli ya coke iraboneka henshi, ihendutse kandi ntigira ingaruka nyinshi ku bijyanye na politiki z'ibidukikije, bigatuma iba ikintu cyiza cyo kugabanya umusaruro mu bwinshi.

II. Uruhare mu gushonga kwa silicon carbide

1. Gutanga isoko ya karuboni
Gutunganya karuboni ya silikoni (SiC) bisaba isoko ya karuboni ifite ubuziranenge bwinshi. Nyuma yo gukaraba, koke ya peteroli ifite ubuziranenge bwinshi igaragaza ubushyuhe buke kandi ikagira ubuziranenge bwinshi, bigatuma habaho isoko ya karuboni ihamye ituma habaho impinduka ikomeye hagati ya silikoni na karuboni kugira ngo habeho karuboni ifite ubuziranenge bwinshi.

2. Gukoresha ibikoresho byo mu bwoko bwa Abrasive
Coke ya peteroli ishobora gukoreshwa mu buryo butaziguye mu gukora ibintu bitera ibyuma bya silicon carbide (urugero: amapine yo gusya, sandpaper). Ubukana bwayo bwinshi no kudashira kwayo bituma iba igikoresho cy'ingenzi mu gutunganya ibyuma, gusiga irangi rya ceramic, n'ibindi bikorwa.

3. Gutunganya Imikorere

• Uburyo bwo kuvura ikarangisho: Gukarisha ikarangisho rya peteroli ku bushyuhe bwa 1300°C bigabanya ingano ya hydrogen kandi byongera graphitization, bikongera imikorere y'amashanyarazi no kwirinda ubushyuhe bw'ibicuruzwa bya silicon carbide.
• Kugenzura Ingano y'Ibice: Guhindura ingano y'ibice bya peteroli ya coke binoza uburyo bwo gukora kristali ya silicon carbide, bikongera uburinganire bw'ibicuruzwa.

III. Uruhare rusesuye n'agaciro k'inganda

1. Kongera ubushobozi bwo gushongesha ibintu
Uburyo amashanyarazi akoreshwa mu gukwirakwiza peteroli hamwe no kudahindagurika kw'ibinyabutabire bya peteroli ya graphitized bigabanya ikoreshwa ry'ingufu mu itanura ry'amashanyarazi, bigagabanya ingendo zo gushongesha, kandi bikongera imikorere myiza. Urugero, mu ikorwa rya silikoni mu nganda, kuvanga peteroli neza bishobora kugabanya ikoreshwa ry'ingufu ho 5%-10%.

2. Kugenzura ubuziranenge
Kugenzura urugero rwa sulfur, ivu, n'umwanda muri peteroli ya coke bigabanya ibintu bitari ibyuma byinjizwa muri silikoni yo mu nganda kandi byongera ubuziranenge bwa silikoni, bigahaza ibyifuzo by'inganda zikora ibintu byo mu rwego rwo hejuru (urugero: silikoni yo mu rwego rwa semiconductor).

3. Guteza imbere inganda
Uko inganda zitunganya ubutare zigenda zitera imbere mu bikorwa binini kandi by’ubwenge, ubuziranenge n’ubuziranenge bwa peteroli coke ya grafitised peteroli bifasha mu gukora electrode pastes nziza cyane na electrode nini za karuboni, bigateza imbere iterambere ry’ikoranabuhanga mu rwego rwose.
