Mu myaka yashize, tekinoroji yo kubyaza umusaruro murugoibishushanyo mbonerayateye intambwe igaragara.Ntabwo bafashe gusa umusaraba utumizwa mu mahanga, ariko rimwe na rimwe barabarenze.Mugukoresha uburyo bushya bwo gukora no gushakisha ibikoresho byiza byo mu rwego rwo hejuru, ibishushanyo mbonera bya grafite birashobora kwihanganira ibihe bikabije hamwe nubushobozi butagereranywa.
Ibintu nyamukuru biranga ibishushanyo mbonera bya grafite nta gushidikanya ko bikwiye kwitonderwa.Ubwa mbere, bafite ubushyuhe bwumuriro mwinshi, bigabanya cyane igihe cyo gushonga, tubikesha gukoresha ibikoresho bibisi nka grafite, bifite ubushyuhe bwiza cyane.Uku kwiyongera kwimikorere ntigutwara igihe n'imbaraga gusa, ahubwo binongera umusaruro mubikorwa byose.
Byongeye kandi, utubuto dufite imbaraga zo kurwanya ubushyuhe kandi dushobora kwihanganira ubushyuhe bugera kuri 1200 kugeza 1600 ° C.Iyi miterere idasanzwe ituma biba byiza mubisabwa bisaba ubushyuhe bwo hejuru, nk'ibyuma bikozwe hamwe na fondasiyo.Ubushobozi bwo guhangana nubushyuhe bukabije butabangamiye imikorere ni umukino uhindura umukino mubikorwa byinshi byinganda.
Imwe mu miterere itangaje yibi bibumbano bya grafite nuburyo bwiza bwo kurwanya ruswa.Bagaragaza imbaraga zikomeye nubwo bahanganye nibikoresho byashongeshejwe cyane, byemeza kuramba no gukora neza.Uku kurwanya ruswa kwagura uburyo bwo gukoresha izo ngamba, cyane cyane mu nganda z’imiti n’ibyuma.
Byongeye kandi, imbaraga zayo zo guhangana nubushyuhe butuma iruta ibicuruzwa bisa.Graphite crucibles yerekana elastique mugihe cyo gukonjesha no gushyuha byihuse, bigatuma bidashoboka cyane kumeneka no kumeneka.Uku kuramba kurwego rwo hejuru ntabwo kuzamura umutekano gusa ahubwo binatanga ikiguzi kinini cyo kuzigama mugabanya ibikenewe kubasimburwa kenshi.
Graphite crucibles ikoreshwa cyane mubikorwa bitandukanye bitewe nubushyuhe bwiza bwumuriro hamwe nubushyuhe bwo hejuru.Izi mbuto zifite coefficient nkeya yo kwagura ubushyuhe kandi irwanya ihinduka ritunguranye ryubushyuhe.Barashobora kwihanganira ubushyuhe bwihuse no gukonja batiriwe bahura ningutu zikomeye, bakemeza imikorere myiza kandi yizewe.
Graphite crucibles ifite ingero ntangarugero zo kurwanya ruswa ya acide na alkaline, bigatuma iba ingirakamaro muri laboratoire no mu nganda zikora imiti.Ihungabana ryiza ryimiti yerekana imiti iramba kandi irashobora gukoresha neza imiti myinshi.
Ibigize grafite ikomeye ni naturel ya flake grafite nkibikoresho nyamukuru.Ifashwe hamwe ukoresheje ibifunga bidasanzwe byitwa amakara yumuriro wa plastike.Ihuriro ridasanzwe ryemeza ko umusaraba wa grafite ukomeza uburinganire bwimiterere mubihe bibi, bitanga ibisubizo bihamye mubikorwa bitandukanye.
Kuza kw'ibicuruzwa byakorewe mu gihugu imbere ntibisobanura gusa ikoranabuhanga, ahubwo binashyigikira iterambere ry'inganda zaho.Ibicuruzwa byakorewe mu karere, ubuziranenge bufite ireme bigabanya gushingira ku bicuruzwa bitumizwa mu mahanga mu gihe bitanga ibiciro byapiganwa ku bucuruzi butandukanye.Iri terambere ritanga inzira yo kwihaza no gushimangira imiterere y’inganda mu gihugu.
Muncamake, udushya mubikorwa bya grafite byingenzi byateje imbere cyane, birenze ibicuruzwa bisa nibitumizwa mu mahanga muburyo bwo gukora no kuramba.Ubushuhe buhebuje bwumuriro, kurwanya ubushyuhe bwiza, kurwanya ruswa no kurwanya ubushyuhe bwumuriro bituma biba ingirakamaro mubikorwa bitandukanye byinganda.Hamwe n'iterambere, inganda zikomeye za grafite zo mu gihugu zagize uruhare runini mu kuzamuka mu nganda mu gihugu no kwigira.
