Carbon graphite, inozivikanwawo se graphite kana graphite zvinhu, chinhu chakanakisa chepamusoro-tembiricha zvinhu zvine akawanda anokatyamadza maitiro ekuita.Mukushanda kwepamusoro-tembiricha, kunzwisisa kunyungudika kwekabhoni graphite kwakakosha sezvo ichikanganisa zvakananga kugadzikana uye kushandiswa kwezvinhu munzvimbo dzinopisa zvakanyanya.
Carbon graphite chinhu chinoumbwa nekabhoni maatomu, ane akasiyana makristasi zvimiro.Chimiro chegraphite chinonyanyozivikanwa chiumbwa chakaiswa, apo maatomu ekabhoni akarongwa muzvikamu zvine hexagonal, uye kubatana pakati pematanho hakuna kusimba, saka maseru anogona kutsvedza zviri nyore.Ichi chimiro chinopa kabhoni graphite neyakanakisa yekupisa conductivity uye lubricity, ichiita kuti iite zvakanaka mukupisa kwepamusoro uye kukweshera kwenzvimbo.
Kunyunguduka kwekabhoni graphite
Kunyungudika kwekabhoni graphite inoreva tembiricha apo kabhoni graphite inoshandura kubva pakasimba kuenda kumvura pasi pemamiriro ekunze.Iko kunyunguduka kwegraphite kunoenderana nezvinhu zvakaita sekristaro yayo chimiro uye kuchena, saka inogona kuve nekumwe shanduko.Nekudaro, kazhinji, nzvimbo yekunyungudika yegraphite iri mukati meyepamusoro-tembiricha renji.
Kunyungudika kwegirafu kunowanzoita 3550 degrees Celsius (kana kuti anenge 6422 degrees Fahrenheit).Izvi zvinoita kuti graphite ive yakanyanya-yepamusoro-tembiricha inodzivirira zvinhu inokodzera kwakasiyana-siyana kudziya kwepamusoro-soro, senge kunyungudutsa simbi, magetsi arc furnaces, semiconductor kugadzirwa, uye marabhoritari mavira.Kunyungudika kwayo kwakakwirira kunoita kuti graphite ichengetedze kugadzikana kwayo kwemaitiro uye kushanda munzvimbo idzi dzakanyanyisa kupisa, pasina kuve nyore kunyunguduka kana kurasikirwa nemagetsi.
Nekudaro, zvakakosha kucherechedza kuti kunyungudika kwegraphite kwakasiyana nekupisa kwayo.Kunyange zvazvo graphite isinganyunguduki pakupisa kwakanyanya, inogona kupisa pasi pemamiriro ezvinhu akaipisisa (akadai semhepo ine oxygen yakawanda).
Kushandiswa kwekushisa kwepamusoro kwegraphite
Iyo yakakwira yekunyungudika yegraphite inoita basa rakakosha muminda yakawanda, uye anotevera ndeamwe eakanyanya-tembiricha maapplication:
1. Kunyunguduka kwesimbi
Mukuita kunyungudutswa kwesimbi, yakakwira melting point graphite inowanzoshandiswa sezvikamu zvakaita semacrucibles, electrodes, uye vira remoto.Inogona kumira zvakanyanya tembiricha uye ine yakanakisa thermal conductivity, iyo inobatsira kunyunguduka nekukanda simbi.
2. Semiconductor kugadzira
Iyo semiconductor yekugadzira maitiro inoda yakakwirira-tembiricha mavira kugadzirira semiconductor zvinhu zvakaita secrystalline silicon.Graphite inoshandiswa zvakanyanya sechoto uye kupisa chinhu nekuti inogona kushanda pakupisa kwakanyanya uye inopa yakagadzikana yekupisa conductivity.
3. Chemical industry
Graphite inoshandiswa muindasitiri yemakemikari kugadzira makemikari reactor, mapaipi, zvinhu zvekudziya, uye zvinokonzeresa zvekutsigira zvinhu.Kugadzikana kwayo kwepamusoro-tembiricha uye kushorwa kunoita kuti ive sarudzo yakanaka yekubata zvinhu zvinoparadza.
4. Chitofu cherabhoritari
Zvitofu zverabhoritari zvinowanzo shandisa graphite sechinhu chekudziya kune akasiyana-siyana ekupisa kwekushisa uye kugadzirisa zvinhu.Graphite crucibles zvakare inowanzoshandiswa kunyungudika sampuli uye kuongorora kupisa.
5. Aerospace uye Nuclear Industry
Mumaindasitiri emuchadenga uye zvenyukireya, graphite inoshandiswa kugadzira zvinhu zvinodziya zvakanyanya uye zvinhu, zvakaita semafuta ekupfekedza zvinhu mumagetsi enyukireya.
Kusiyana uye Mashandisirwo eGraphite
Kuwedzera kune yakajairwa graphite, kune mamwe marudzi ekabhoni graphite akasiyana, akadai se pyrolytic graphite, modified graphite, metal based graphite composite, nezvimwewo, ane akakosha maitiro ekuita mune akasiyana-tembiricha maapplication.
Pyrolytic Graphite: Iyi mhando yegraphite ine yakakwirira anisotropy uye yakanakisa yekupisa conductivity.Inoshandiswa zvakanyanya muminda senge aerospace uye semiconductor indasitiri.
Modified graphite: Nekuunza tsvina kana kugadziridzwa kwepasi mugraphite, chaiyo zvivakwa zvinogona kuvandudzwa, sekusimudzira kusagadzikana kwekuora kana kuvandudza thermal conductivity.
Metal based graphite composite materials: Izvi zvinosanganiswa zvinhu zvinosanganisa graphite nesimbi yakavakirwa zvinhu, zvine yakakwirira-tembiricha zvimiro zve graphite uye mechanical zvimiro zvesimbi, uye zvakakodzerwa nepamusoro-tembiricha zvimiro uye zvikamu.
Ckubatanidza
Iyo yakanyanya kunyungudika yekabhoni graphite inoita kuti ive chinhu chakakosha mumhando dzakasiyana dzekupisa tembiricha.Zvingave mukunyungudusa simbi, kugadzira semiconductor, indasitiri yemakemikari, kana mavira emurabhoritari, graphite inoita basa rakakosha mukuona kuti maitiro aya anogona kuitwa zvakatsiga pakupisa kwakanyanya.Panguva imwecheteyo, akasiyana akasiyana uye kugadziridzwa kwegraphite zvakare kunoita kuti ive yakakodzera kune akasiyana chaiwo mashandisirwo, ichipa akasiyana mhinduro kune maindasitiri nesainzi nharaunda.Nekuenderera mberi kwekuvandudza tekinoroji, tinogona kutarisira kuona kubuda kwezvimwe zvitsva-yepamusoro-tembiricha zvinhu kuti zvisangane nezvinogara zvichichinja zvinodiwa zvemhando yepamusoro yekupisa.
