Ibyiza bya grafite nibikoresho byo gushyushya amashanyarazi kumatanura ya vacuum

Hamwe nogutezimbere urwego rwumuriro wo kuvura ubushyuhe bwa vacuum, kuvura ubushyuhe bwa vacuum bifite ibyiza byihariye, kandi kuvura ubushyuhe bwa vacuum byakunzwe nabantu muruganda bitewe nurukurikirane rwibyiza nko gutesha agaciro, kwangirika, okisijeni yubusa no kwikora. Ariko, birashishikaje ko itanura ryubushyuhe bwa vacuum rifite urwego rwo hejuru kubintu bishyushya amashanyarazi, nko guhindura ubushyuhe bwo hejuru, kuvunika Volatilisation byabaye ikintu cyingenzi kibuza iterambere ryiterambereitanura.
Kugira ngo iki kibazo gikemuke, inganda zerekeje ibitekerezo kuri grafite.Igishushanyoikozwe mubindi byuma kandi ifite ibyiza bitagira inenge. Byumvikane ko grafite ikunzwe cyane muburyo butandukanye bwo gutanura ubushyuhe bwa vacuum nkibikoresho byo gushyushya amashanyarazi.
Noneho ibyiza byo gushushanya ubushyuhe bwa grafite vacuum ibikoresho byo gushyushya amashanyarazi
1) Kurwanya ubushyuhe bwinshi: aho gushonga ya grafite ni 3850 ± 50 ℃ naho guteka ni 4250 ℃. Nubwo yatwikwa nubushyuhe bukabije bwa arc, gutakaza ibiro ni bito cyane kandi coefficient yo kwagura ubushyuhe ni nto cyane. Imbaraga za grafite ziyongera hamwe no kwiyongera kwubushyuhe. Kuri 2000 ℃, imbaraga za grafite zikubye kabiri.
2) Umuyoboro nubushyuhe bwumuriro: ubwikorezi bwa grafite burenze inshuro 100 ugereranije nubutare rusange butari ubutare. Ubushyuhe bwumuriro burenze ubw'ibyuma, ibyuma, isasu nibindi bikoresho byuma. Amashanyarazi agabanuka hamwe no kwiyongera kwubushyuhe. Ndetse no ku bushyuhe bwo hejuru cyane, grafite iba insulator. Graphite irashobora kuyobora amashanyarazi kuko buri karubone atom ya grafite ikora imigozi itatu gusa ya covalent hamwe nizindikaruboneatome, na buri karubone atom iracyafite electron imwe yubusa kugirango yishyure amafaranga.
3) Amavuta: imikorere ya mavuta ya grafite biterwa nubunini bwa grafite. Ingano nini, ntoya ya coefficient de fraisse, nuburyo bwiza bwo gusiga. Imiti ihamye:igishushanyoifite imiti ihamye yubushyuhe bwicyumba kandi irashobora kurwanya aside, alkali na organic solvent ruswa.
4) Plastike: grafite ifite ubukana bwiza kandi irashobora kuba mubutaka bworoshye. Kurwanya ubushyuhe bwumuriro: iyo grafite ikoreshwa mubushyuhe bwicyumba, irashobora kwihanganira ihinduka rikabije ryubushyuhe nta byangiritse. Iyo ubushyuhe buhindutse gitunguranye, ingano ya grafite ihinduka bike kandi ibice ntibizabaho.
Mugihe cyo gushushanya no gutunganya itanura rya vacuum, dukwiye gutekereza ko kurwanya ibintu byo gushyushya amashanyarazi bihinduka bike hamwe nubushyuhe kandi birwanya guhagarara, bityo grafite nikintu cyatoranijwe.
