Inama zo gukuraho imyanda mu ifu ya grafiti

Igikoresho cya grafiti gikunze gukoreshwa mu gukora ibikoresho by'icyuma na semiconductor. Kugira ngo ibikoresho by'icyuma na semiconductor bigere ku buziranenge runaka no kugabanya ingano y'imyanda, ifu ya grafiti ifite karuboni nyinshi n'imyanda mike irakenewe. Muri iki gihe, ni ngombwa gukuraho imyanda mu ifu ya grafiti mu gihe cyo kuyitunganya. Abakiriya benshi ntibazi uburyo bwo guhangana n'imyanda iri mu ifu ya grafiti. Uyu munsi, Furuite Graphite Editor azavuga ku nama zo gukuraho imyanda mu ifu ya grafiti mu buryo burambuye:

Mu gihe dukora ifu ya grafiti, tugomba kugenzura neza ingano y'imyanda iva mu guhitamo ibikoresho fatizo, guhitamo ibikoresho fatizo bifite ivu rike, no gukumira ubwiyongere bw'imyanda mu gihe cyo gutunganya ifu ya grafiti. Oxyde z'ibintu byinshi by'imyanda zihora zibora kandi zigahinduka umwuka ku bushyuhe bwinshi, bityo tukizeza ko ifu ya grafiti ikorwa iba nziza.

Mu gukora ibikoresho rusange bya graphite, ubushyuhe bw'imbere y'itanura bugera kuri 2300℃ kandi ubushyuhe busigaye bugera kuri 0.1%-0.3%. Iyo ubushyuhe bw'imbere y'itanura buzamuwe bukagera kuri 2500-3000℃, ubushyuhe bw'imyanda isigaye buragabanuka cyane. Mu gukora ibikoresho by'ifu ya graphite, peteroli coke ifite ivu rike ikoreshwa nk'ibikoresho birwanya ubushyuhe n'ibikoresho byo gukingira.

Nubwo ubushyuhe bwa graphitization bwongerwaho gusa kugeza kuri 2800°C, imyanda imwe na imwe iracyagoye kuyikuraho. Hari ibigo bimwe na bimwe bikoresha uburyo nko kugabanya inkingi y'itanura no kongera ubucucike bw'amashanyarazi kugira ngo bikuremo ifu ya graphite, bigabanya umusaruro w'itanura rya graphite ifu kandi byongera ikoreshwa ry'ingufu. Kubwibyo, iyo ubushyuhe bw'itanura rya graphite ifu bugeze kuri 1800°C, gazi isukuye, nka chlorine, freon n'izindi chloride na fluoride, irashyirwamo, kandi ikomeza kongerwamo amasaha menshi nyuma y'ibura ry'ingufu. Ibi ni ukugira ngo hirindwe ko imyanda yakuwemo umwuka ikwirakwira mu itanura mu cyerekezo gitandukanye, no kwirukana imfu yasigaye isukuye mu myenge y'ifu ya graphite binyuze mu gushyiramo azote.
