Igishushanyo gikomeyenigicuruzwa kidasanzwe kigira uruhare runini mugutunganya zahabu, ifeza, umuringa nibindi byuma byagaciro.Nubwo abantu benshi bashobora kuba batabimenyereye, kubyara grafite yabambwe ikubiyemo ibyiciro byinshi bigoye kugirango harebwe ubuziranenge nubukanishi bwibicuruzwa byanyuma.Muri iyi ngingo, tuzacukumbura birambuye kuri buri cyiciro kigira uruhare mubikorwa byo gukora grafite.
Ibyiciro byambere byo gukora ibishushanyo mbonera birimo uburyo bwo kumisha.Nyuma yibyingenzi nibice byayo bishyigikira bimaze gushingwa, birasuzumwa hakurikijwe ibicuruzwa bitarangiye.Iri genzura ryemeza ko abantu babishoboye gusa batera intambwe ikurikira.Nyuma yo gutondeka, bahura nuburyo bwo gusiga, aho ubuso bwingenzi butwikiriwe nubururu.Uru rufunzo rwa glaze rukora intego nyinshi, zirimo kongera ubwinshi nimbaraga za mashini zingenzi, amaherezo bikazamura ubwiza bwarwo muri rusange.
Icyiciro cyo kurasa nigice cyingenzi mubikorwa byo gukora.Harimo gukurikiza igishushanyo mbonera cyubushyuhe bwo mu itanura, bityo ugashimangira imiterere yingenzi.Iyi nzira ningirakamaro kugirango tumenye igihe kirekire kandi cyizewe cyingirakamaro mugihe cyo gutunganya.Ihame ryo kurasa rishobora kugabanywamo ibice bine bitandukanye kugirango wumve neza impinduka zibaho muburyo bukomeye muriki gikorwa.
Icyiciro cya mbere nicyiciro cyo gushyushya no kurasa, kandi ubushyuhe mu itanura bugumaho nka 100 kugeza 300 ° C.Kuri iki cyiciro, ubushuhe busigaye mububasha bukurwaho buhoro buhoro.Fungura itanura rya skylight hanyuma ugabanye umuvuduko wo gushyushya kugirango wirinde ubushyuhe butunguranye.Kugenzura ubushyuhe ni ngombwa muri iki cyiciro, kubera ko ubushuhe bwinshi busigaye bushobora gutera ingirakamaro kumeneka cyangwa guturika.
Icyiciro cya kabiri nicyiciro cyo hasi cyo kurasa, hamwe nubushyuhe bwa 400 kugeza 600 ° C.Mugihe itanura rikomeje gushyuha, amazi aboshye mumbere atangira kumeneka no guhinduka.Ibice nyamukuru A12O3 na SiO2, byahoze bihambirijwe ibumba, bitangira kubaho mubuntu.Ariko, twakagombye kumenya ko igicucu cya glaze hejuru yikibumbano kitarashonga.Kugira ngo wirinde ikintu icyo ari cyo cyose gitunguranye, igipimo cyo gushyuha kigomba kuba gahoro kandi gihamye.Ubushuhe bwihuse kandi butaringaniye burashobora gutuma ingenzi kumeneka cyangwa gusenyuka, bikabangamira ubusugire bwayo.
Kwinjira mu cyiciro cya gatatu, icyiciro cyo hagati cyo kurasa ubusanzwe kibaho hagati ya 700 na 900 ° C.Kuri iki cyiciro, amorphous Al2O3 mubumba yahinduwe igice kugirango ibe Y-kristaline Al2O3.Ihinduka ryongera uburinganire bwimiterere yibyingenzi.Ni ngombwa gukomeza kugenzura neza ubushyuhe muri iki gihe kugirango wirinde ibisubizo bitifuzwa.
Icyiciro cya nyuma nicyiciro cyo hejuru cyo kurasa, hamwe nubushyuhe buri hejuru ya 1000 ° C.Kuri iyi ngingo, igicucu cya glaze amaherezo kirashonga, bigatuma ubuso bwingenzi bworoshye kandi bufunze.Ubushyuhe bwo hejuru nabwo bugira uruhare mu kuzamura muri rusange imbaraga zumukanishi no kuramba.
Byose muri byose, uburyo bwo gukora ibishushanyo mbonera bya grafite birimo ibyiciro byinshi.Kuva kumisha no kugenzura ibicuruzwa byarangiye kugeza kurabagirana no kurasa, buri ntambwe ningirakamaro kugirango harebwe ubwiza nubwizerwe bwa grafite ya nyuma ikomeye.Gukurikiza ingamba zo kugenzura ubushyuhe no gukomeza ubushyuhe bukwiye ni ngombwa mu gukumira inenge cyangwa impanuka zishobora kubaho.Igisubizo cyanyuma nigishushanyo mbonera cyiza cyane gishobora kwihanganira uburyo bukomeye bwo gutunganya amabuye y'agaciro.
