Ibyiza no gukoresha igishushanyo

Ibicuruzwa bisobanura: igishushanyo

Ifu ya Graphite yoroshye, umukara wumukara, amavuta kandi irashobora kwanduza impapuro. Gukomera ni 1-2, kandi kwiyongera kuri 3-5 hamwe no kwiyongera kwanduye kuruhande rwerekezo. Uburemere bwihariye ni 1.9-2.3. Mugihe cyo kwigunga kwa ogisijeni, aho gushonga hejuru ya 3000 ℃, nimwe mumabuye y'agaciro arwanya ubushyuhe. Ku bushyuhe bwicyumba, imiterere yimiti yifu ya grafite irahagaze neza, idashonga mumazi, acide acide, alkali ya alkali na solge organic; ibikoresho bifite ubushyuhe bwinshi kandi birwanya ubukana, kandi birashobora gukoreshwa nkibikoresho byangiritse, bitwara ibintu, birinda kwambara kandi bisiga amavuta.

Bitewe nuburyo bwihariye, grafite ifite ibimenyetso bikurikira: 1. Kurwanya ubushyuhe bwinshi: aho gushonga kwa grafite ni 3850 ± 50 and, naho guteka ni 4250 ℃. Nukuvuga ko igipimo cyo kugabanya ibiro hamwe na coefficient yo kwagura ubushyuhe ni bito cyane mugihe ukoresheje ultra-high ubushyuhe arc gucumura, kandi imbaraga za grafite ziyongera hamwe no kwiyongera kwubushyuhe. Kuri 2000 ℃, imbaraga za grafite zikubye kabiri. 2. Amavuta: amavuta ya grafite biterwa nubunini bwa grafite. Ingano nini nini, ntoya ya coefficient de friction ni ntoya, kandi nibikorwa byiza byo gusiga ni. 3. Imiterere ya chimique: grafite ifite imiti ihamye yubushyuhe bwicyumba, irwanya aside, alkali na organic solvent corrosion. 4. Plastike: grafite ifite ubukana bwiza kandi irashobora gukanda mumpapuro zoroshye. 5. Kurwanya ubushyuhe bwumuriro: iyo grafite ikoreshwa mubushyuhe bwicyumba, irashobora kwihanganira ihinduka rikabije ryubushyuhe nta byangiritse. Iyo ubushyuhe buzamutse gitunguranye, ingano ya grafite ntizahinduka cyane kandi ntihazabaho gucika.

Ikoreshwa:

1. Nkibikoresho byangiritse: grafite nibicuruzwa byayo bifite ibimenyetso biranga ubushyuhe bwinshi nimbaraga nyinshi. Zikoreshwa cyane cyane mubikorwaigishushanyo mboneramu nganda zibyuma, kandi zisanzwe zikoreshwa nkibikoresho byo gukingira ibyuma no gutanura itanura.

2. Nkibikoresho byo kwisiga bidashobora kwambara: grafite ikoreshwa kenshi nk'amavuta mu nganda zimashini. Amavuta yo gusiga mubisanzwe ntabwo akwiranye n'umuvuduko mwinshi, ubushyuhe bwinshi n'umuvuduko mwinshi.

3. Graphite ifite imiti ihamye. Ikoreshwa cyane mu nganda zikomoka kuri peteroli, hydrometallurgie, umusaruro-fatizo wa aside, fibre synthique, gukora impapuro nizindi nzego zinganda, zishobora kuzigama ibikoresho byinshi byicyuma.

4. Graphite irashobora gukoreshwa nkikaramu yamakaramu, pigment na polishing agent. Nyuma yo gutunganywa bidasanzwe, grafite irashobora gukorwa mubikoresho bitandukanye kugirango bikoreshwe ninzego zinganda zibishinzwe.
