Mapepala a graphite, monga -ogwira ntchito kwambiri m'mafakitale, amagwiritsidwa ntchito kwambiri m'magawo monga zitsulo, chemical engineering, semiconductors, ndi mphamvu zatsopano. Kusankhidwa kwake kwazinthu kumakhudza mwachindunji kudalirika kwa zida, moyo wautali, komanso magwiridwe antchito. Kusankha zinthu zasayansi kumafuna kuganizira mozama zinthu zingapo, kuphatikiza matenthedwe amafuta, kukana kwa dzimbiri, mphamvu zamakina, ndi mtengo.
Based on substrate type, graphite sheet is primarily categorized into three types: natural graphite, artificial graphite, and composite graphite. Natural graphite has a high purity (typically >95%) komanso matenthedwe abwino kwambiri, koma mphamvu yotsika yamakina. Ndizoyenera kugwiritsa ntchito matenthedwe opangira matenthedwe okhala ndi zofunikira zochepa zamapangidwe, monga ma elekitirodi ang'anjo zamagetsi. Ma graphite Opanga, opangidwa kudzera-pakutentha kwambiri, amakhala ndi kachulukidwe kakang'ono (1.8–2.2 g/cm³) ndi mphamvu yopondereza (mpaka 30 MPa). Limaperekanso -kutentha kolimba kwambiri (kokhoza kugwiritsidwa ntchito nthawi yayitali{{9}kutentha mpaka madigiri 3000 ), zomwe zimapangitsa kukhala njira yabwino kwambiri yopangira ma chemical reactor ndi ma insulation layers mu single{11}}crystal silicon kukula ng'anjo. Ma graphite ophatikizika, powonjezera zolimbitsa thupi monga mpweya wa kaboni ndi ufa wachitsulo, zimawonjezera mphamvu ndi kukana kuvala, kuwonetsa ntchito yake yabwino kwambiri m'mabwato a graphite pamakampani opanga ma photovoltaic ndi zida za semiconductor etching.
Ma microstructure azinthu ndizofunikanso. -zoyera za graphite (zokhala ndi phulusa<20 ppm) effectively avoids contamination from metal impurities and is suitable for high-temperature load platforms in semiconductor manufacturing. Isotropic graphite, through isostatic pressing, ensures uniform three-dimensional properties, making it particularly suitable for heat dissipation components in precision molds. For highly corrosive environments (such as hydrofluoric acid and molten alkali), modified graphite sheets impregnated with resin or metal coatings are used, which can improve permeability by 3–5 times.
Pazachuma, ma graphite wamba a mafakitale ({0}}grade artificial graphite (kachulukidwe 1.6 g/cm³) amangotengera -gawo limodzi mwa magawo atatu a ma graphite apamwamba kwambiri-opangidwa ndi isostatically pressed graphite, koma moyo wake ukhoza kufupikitsidwa ndi 40%. Muzochita zauinjiniya, njira ya "kusankhira zinthu" nthawi zambiri imatsatiridwa: -kuyera kwa graphite kumagwiritsidwa ntchito polumikizana pakati kuti zitsimikizire kuyera, pomwe ma graphite wamba amagwiritsidwa ntchito popanga zotumphukira kuti achepetse mtengo.
Mwachidule, kusankha zipangizo graphite mbale ayenera zochokera ntchito zofunika za zochitika ntchito, kufunafuna muyezo mulingo woyenera kwambiri madutsidwe matenthedwe matenthedwe, kukana dzimbiri, mphamvu mawotchi ndi mtengo, ndi maximizing ubwino uinjiniya mwa sayansi yofananira katundu zakuthupi.
