Ibyiza bya Graphite Crucibles: Ibice byingenzi muri Metallurgie ninganda zikora imiti

Mu nganda zinyuranye, hariho imyumvire itari yo yerekeye akamaro kaigishushanyo mbonera. Abantu benshi bibeshya bemeza ko ibyo bicuruzwa bifite akamaro gake ku isoko, bakeka ko bidafite akamaro. Ariko, iyi myumvire ntishobora kuba kure yukuri. Mugihe ibishushanyo mbonera bya grafite bishobora kugaragara nkubwubatsi bworoshye - bwagenewe kubamo ibintu bitandukanye - kubura kwabo bishobora gutera ibibazo bikomeye haba mubyuma bya chimique na chimique. Reka ducukumbure ibyiza bya grafite ya musaraba hanyuma dushakishe uburyo bwabo butandukanye.
1. Guhindagurika no Kwihangana
Imwe mu nyungu zigaragara za grafite yabambwe iri muburyo bwinshi. Izi mbuto zigizwe cyane cyane na grafite na quartz, zivangwa n’imiti itandukanye y’imiti hanyuma bigakorerwa umuriro mwinshi kugirango ubyare umusaruro. Iyi mikorere idasanzwe ituma umusaraba wa grafite ushobora kwihanganira aside irike cyane, alkaline, na ruswa yangiza, bigatuma iba ingirakamaro mu nganda zikora imiti. Igeragezwa ryinshi ryakozwe n'abahanga ryerekanye ko na aqua regia - imvange ya acide yangirika cyane - ishobora kubikwa neza mumisaraba ya grafite.
Byongeye kandi, ibishushanyo mbonera bya grafite byerekana ubushyuhe budasanzwe, bushobora kwihanganira ubushyuhe burenga dogere selisiyusi 5000 nta kwangirika gukomeye. Ibi bituma baberamo ibyuma bishongeshejwe, aluminium, nibindi byuma ndetse no mumazi yabyo, bishimangira akamaro kabo mubikorwa bitandukanye.
2. Ubwiza butavuguruzanya
Ubwiza bwibibumbano bya grafite nibindi byiza byingenzi. Izi mbuto zagenewe guhangana n’umuvuduko ukabije wo hanze, bigatuma zirwanya cyane iterabwoba keretse zikoreshejwe imbaraga zirenze ubushobozi bwazo. Igikorwa cyo gukora cya buri gishushanyo cyibanze gikurikiza amahame akomeye, cyemeza neza muri buri ntambwe. Binyuze muri ubu buryo bwitondewe, ibicuruzwa byanyuma bishobora gufatwa nkibikwiye intego.
Buri gishushanyo kiboneka kigeragezwa cyiza mbere yo kugezwa kubakiriya. Inzego zibishinzwe zikora igenzura ridasanzwe kuri ibyo bicuruzwa, kandi aho ariho hose kutubahiriza amategeko bishobora gutuma umusaruro uhagarara ndetse n’amande menshi, cyangwa se n’ikigo cy’inganda. Ingamba zikaze zirahari kubera ingaruka zishobora kuba zasohotse zishobora gutera ubuzima bwabantu. Kwirinda kumeneka gutya bisaba gukemura ikibazo mumuzi yacyo, duhereye kumusaruro wizo ngirakamaro.
