O le pepa kalafi, e pei o se -malaga tau alamanuia maualuga, e masani ona fa'aogaina i matā'upu e pei o metallurgy, chemical engineering, semiconductors, ma le malosi fou. O lona filifilia o meafaitino e a'afia sa'o ai le fa'atuatuaina o meafaigaluega, le umi o le ola, ma le fa'aogaina lelei. O mea fa'asaienisi filifilia e mana'omia ai le iloiloga atoatoa o le tele o mea, e aofia ai le fa'avevelaina o le vevela, tete'e o le pala, malosi fa'ainisinia, ma le tau.
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%) ma sili atu le vevela conductivity, ae maualalo le malosi masini. E fetaui lelei mo le faʻaogaina o le vevela ma le maualalo o manaʻoga faʻatulagaina, e pei o pads electrode mo ogaumu eletise. graphite fa'akomepiuta, fa'agaioia e ala i le -maualuga fa'agasologa kalafi, e maualuga lona mafiafia (1.8–2.2 g/cm³) ma le malosi fa'amalosi (e o'o i le 30 MPa). O lo'o ofoina mai ai fo'i tulaga maualuga -tete'e vevela (mafai ona fa'aoga umi-i le vevela e o'o atu i le 3000 tikeri), ma avea ai ma filifiliga lelei mo linings reactor kemikolo ma apa fa'a'ese'ese i totonu-umu fa'atupu fa'ama'i tioata tasi. graphite tu'ufa'atasi, e ala i le fa'aopoopoina o fa'amalosi e pei o le alava kaponi ma le pa'u u'amea, e fa'apaleni atili ai le malosi ma le fa'ato'a fa'alavalava, fa'aalia ai lona tulaga mata'ina i va'a graphite mo le alamanuia photovoltaic ma masini etching semiconductor.
E taua fo'i le fa'ameamea ole microstructure. maualuga-kafite mama (mea i totonu o le lefulefu<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.
E tusa ai ma le tamaoaiga, o mea masani -kalafi fa'akomepiuta (density 1.6 g/cm³) tau na'o le tasi-tolu o le maualuga-mama o le kalafi fa'aisaisaisa, ae o lona umi e mafai ona fa'apu'upu'u i le sili atu i le 40%. I fa'ainisinia fa'ainisinia, e masani ona fa'aogaina se ta'iala "fa'avasega meafaitino": maualuga -ma'a graphite e fa'aoga mo mea fa'afeso'ota'i autu ina ia mautinoa ai le mama, ae fa'aaoga graphite masani mo fa'apalapala fa'afale e fa'aitiitia ai tau.
I le aotelega, o le filifilia o mea faʻapipiʻi graphite e tatau ona faʻavae i luga o le faʻatinoga o manaʻoga o le faʻataʻitaʻiga o le talosaga, saili le paleni sili ona lelei i le va o le vevela, faʻafefeteina, malosi faʻainisinia ma tau, ma faʻateleina faʻamanuiaga faʻainisinia e ala i mea faʻasaienisi faʻatusatusa mea.
