Malo Osungunuka a Carbon Graphite: Magwiridwe Ofunika Kwambiri pa Kutentha Kwambiri

Carbon graphite, yomwe imadziwikanso kuti graphite kapena graphite material, ndi chinthu chabwino kwambiri chotentha kwambiri chokhala ndi makhalidwe ambiri ochititsa chidwi.Pazotentha kwambiri, kumvetsetsa malo osungunuka a carbon graphite ndikofunikira chifukwa kumakhudza mwachindunji kukhazikika ndi kugwiritsiridwa ntchito kwa zinthu m'malo otentha kwambiri.

Mpweya wa graphite ndi chinthu chopangidwa ndi maatomu a carbon, okhala ndi makristalo osiyanasiyana.Chodziwika kwambiri cha graphite ndi mawonekedwe osanjikiza, pomwe maatomu a kaboni amapangidwa m'magawo a hexagonal, ndipo kulumikizana pakati pa zigawo kumakhala kofooka, kotero kuti zigawozo zimatha kutsika mosavuta.Kapangidwe kameneka kamapangitsa carbon graphite kukhala ndi matenthedwe abwino kwambiri amafuta ndi mafuta, kupangitsa kuti izichita bwino m'malo otentha komanso amakangana kwambiri.

 

Malo osungunuka a carbon graphite

Malo osungunuka a carbon graphite amatanthauza kutentha komwe mpweya wa graphite umasintha kuchoka ku cholimba kupita kumadzimadzi pansi pa mphamvu ya mumlengalenga.Malo osungunuka a graphite amadalira zinthu monga mawonekedwe ake a kristalo ndi chiyero, kotero akhoza kukhala ndi kusintha kwina.Komabe, nthawi zambiri, malo osungunuka a graphite ali mkati mwa kutentha kwakukulu.

Malo osungunuka a graphite nthawi zambiri amakhala pafupifupi madigiri 3550 Celsius (kapena pafupifupi madigiri 6422 Fahrenheit).Izi zimapangitsa kuti ma graphite akhale zinthu zosagwirizana ndi kutentha kwambiri zomwe zimayenera kugwiritsidwa ntchito potentha kwambiri, monga kusungunula zitsulo, ng'anjo yamagetsi yamagetsi, kupanga semiconductor, ndi ng'anjo za labotale.Kusungunuka kwake kumapangitsa kuti graphite ikhalebe yokhazikika komanso yogwira ntchito m'madera otentha kwambiri, popanda kusungunuka kapena kutaya mphamvu zamakina.

Komabe, ndikofunika kuzindikira kuti malo osungunuka a graphite ndi osiyana ndi malo ake oyaka.Ngakhale kuti graphite sisungunuka pa kutentha kwambiri, imatha kutentha kwambiri (monga malo okhala ndi okosijeni).

 

Kutentha kwakukulu kwa graphite

Malo osungunuka a graphite amatenga gawo lofunikira m'magawo angapo, ndipo zotsatirazi ndi zina mwazofunikira kwambiri pakutentha kwambiri:

1. Kusungunula zitsulo

Panthawi yosungunula zitsulo, graphite yosungunuka kwambiri imagwiritsidwa ntchito ngati zigawo monga crucibles, electrode, ndi ng'anjo yamoto.Imatha kupirira kutentha kwambiri ndipo imakhala ndi matenthedwe abwino kwambiri, omwe amathandiza kusungunula ndikuponya zitsulo.

2. Kupanga semiconductor

Njira yopangira semiconductor imafuna ng'anjo zotentha kwambiri kuti zikonzekeretse zida za semiconductor monga crystalline silicon.Graphite imagwiritsidwa ntchito kwambiri ngati ng'anjo komanso chotenthetsera chifukwa imatha kugwira ntchito kutentha kwambiri komanso kupereka matenthedwe okhazikika.

3. Makampani opanga mankhwala

Graphite amagwiritsidwa ntchito m'makampani opanga mankhwala kupanga ma reactors amankhwala, mapaipi, zinthu zotenthetsera, ndi zida zothandizira.Kukhazikika kwake kwa kutentha kwambiri komanso kukana kwa dzimbiri kumapangitsa kuti ikhale chisankho chabwino chogwira zinthu zowononga.

4. Chitofu chamu labotale

Masitovu a labotale nthawi zambiri amagwiritsa ntchito graphite ngati chinthu chotenthetsera pazoyesera zosiyanasiyana zotentha kwambiri komanso kukonza zinthu.Ma graphite crucibles amagwiritsidwanso ntchito nthawi zambiri kusungunula ndi kusanthula kutentha.

5. Makampani a Zamlengalenga ndi Nyukiliya

M'mafakitale apamlengalenga ndi zida za nyukiliya, ma graphite amagwiritsidwa ntchito popanga zinthu zotentha kwambiri komanso zinthu zina, monga zomangira ndodo zamafuta mu zida zanyukiliya.

 

Kusiyanasiyana ndi Kugwiritsa Ntchito Graphite

Kuphatikiza pa ma graphite wamba, palinso mitundu ina yamitundu ya carbon graphite, monga pyrolytic graphite, modified graphite, zitsulo zopangidwa ndi graphite composites, ndi zina zambiri, zomwe zimakhala ndi magwiridwe antchito apadera pamagwiritsidwe osiyanasiyana a kutentha kwambiri.

Pyrolytic Graphite: Mtundu uwu wa graphite uli ndi anisotropy wapamwamba komanso matenthedwe abwino kwambiri.Amagwiritsidwa ntchito kwambiri m'magawo monga mlengalenga ndi semiconductor makampani.

Kusinthidwa kwa graphite: Poyambitsa zonyansa kapena kusinthidwa kwapamwamba kukhala graphite, zinthu zinazake zimatha kuwongolera, monga kukulitsa kukana kwa dzimbiri kapena kuwongolera matenthedwe.

Zitsulo zochokera ku graphite zida zophatikizika: Zida zophatikizika izi zimaphatikiza ma graphite ndi zitsulo zopangidwa ndi zitsulo, zomwe zimakhala ndi kutentha kwapamwamba kwa graphite ndi zida zamakina azitsulo, ndipo ndizoyenera zopangira zotentha kwambiri komanso zigawo.

 

Ckuphatikiza

Kusungunuka kwambiri kwa carbon graphite kumapangitsa kukhala chinthu chofunika kwambiri pa ntchito zosiyanasiyana zotentha kwambiri.Kaya ndikusungunula zitsulo, kupanga ma semiconductor, makampani opanga mankhwala, kapena ng'anjo za labotale, graphite imagwira ntchito yofunika kwambiri powonetsetsa kuti izi zitha kuchitika mokhazikika pakutentha kwambiri.Panthawi imodzimodziyo, zosiyana siyana ndi kusinthidwa kwa graphite kumapangitsanso kukhala koyenera kwa ntchito zosiyanasiyana, kupereka mayankho osiyanasiyana kwa mafakitale ndi asayansi.Ndi chitukuko chosalekeza cha teknoloji, tikhoza kuyembekezera kuwona kutuluka kwa zipangizo zatsopano zowonjezera kutentha kuti tikwaniritse zosowa zomwe zimasintha nthawi zonse za njira zotentha kwambiri.
