Synthetic graphite o se polycrystalline tutusa ma crystallography. E tele ituaiga o graphite fa'akomepiuta ma fa'agasologa o gaosiga eseese.
I se tulaga lautele, o mea uma o le graphite e maua pe a uma le carbonization o mea faʻalaʻau ma graphitization i le vevela maualuga e mafai ona taʻua faʻatasi o graphite faʻapitoa, e pei o le carbon (graphite) fiber, pyrolytic carbon (graphite), foam graphite, ma isi.
I le uiga vaapiapi, graphite fa'akomepiuta e masani lava ona faasino i le tele o mea mautu, e pei o le graphite electrode, isostatic graphite, faia e ala i batching, fefiloi, molding, carbonization (ua taʻua o le taoina i alamanuia) ma graphitization, ma le maualalo o le eleelea i totonu o le malala mea mata. (coke petroleum, coke asphalt, etc.) as aggregate, coal pitch as binder.
E tele ituaiga o graphite faʻapitoa, e aofia ai le paʻu, fiber ma le poloka, ae o le vaapiapi o le graphite faʻapitoa e masani ona poloka, lea e manaʻomia ona faʻaogaina i se foliga patino pe a faʻaaogaina. E mafai ona manatu o se ituaiga o mea multiphase, e aofia ai le vaega graphite suia e carbon particles e pei o le suauu coke po o le asphalt coke, o le vaega graphite suia e le koale pitch fusifusi ufiufi faataamilo i vaega, o le faaputuga vaega po o pores faia e le koale. pitch binder pe a uma togafitiga vevela, ma isi. I le tulaga lautele, o le maualuga o le vevela vevela togafitiga, o le maualuga o le tikeri o le graphitization. Le gaosiga faʻapisinisi o graphite faʻapitoa, o le tikeri o le graphitization e masani ona itiiti ifo i le 90%.
Pe a faatusatusa i le graphite natura, graphite faafoliga e vaivai le vevela ma le conductivity eletise, lubricity ma plasticity, ae o le graphite faafoliga foi e sili atu le ofuina tetee, corrosion tetee ma maualalo permeability nai lo graphite natura.
O mea mataʻina mo le gaosia o le graphite faʻapitoa e aofia ai le suauʻu coke, nila coke, coke asphalt, koale pitch, carbon microspheres, ma isi. exchanger ma isi.
O le faʻaaogaina o oloa o le graphite faʻapitoa e faʻaalia i vaega nei:
1. Graphite electrode: Faʻatasi ai ma le suauʻu coke ma nila coke e pei o mea mata ma le koale pitch e pei o le fusifusia, o le graphite electrode e faia e calcination, batching, fefiloi, fetaomi, taoina, graptitization ma masini. E faʻaaogaina lautele i le ogaumu eletise uʻamea, silicon alamanuia, phosphorus samasama ma isi meafaigaluega e ala i le tuʻuina atu o le malosi eletise i foliga o le arc e vevela ma faʻafefe ai le moliaga.
2. Anode muai tao: faia i le suauu coke e pei o mea mata ma le koale pitch e pei o fusi e ala i calcination, batching, fefiloi, oomiina, roasting, impregnation, graphitization ma masini, e masani ona faaaogaina e pei o le anode conductive o meafaigaluega alumini electrolytic.
3. Faʻamau, faʻamaufaʻailoga mama: faʻafeiloaʻi mea faʻasalalau faʻasalalau, faʻaogaina lautele graphite faʻaogaina o piston mama, faʻamaufaʻailoga mama ma bearings, galue e aunoa ma le faʻaopopoina o le suauu lubricating.
4. Heat exchanger, vasega faamama: graphite faafoliga ei ai uiga o le corrosion tetee, conductivity vevela lelei ma maualalo permeability. E faʻaaogaina lautele i le alamanuia vailaʻau e fai ai le vevela, faʻafefete, faʻafefe, faamama ma isi meafaigaluega.
5. Faʻapitoa graphite: faʻatasi ai ma le maualuga o le suauʻu coke e pei o mea mata, koale pitch poʻo le resin synthetic e pei o le fusifusia, e ala i le sauniaina o meafaitino mata, faʻapipiʻiina, lomiina, faʻamalosi, tuʻimomomoina, faʻafefiloi le lomiga, faʻafefeteina, faʻafefeteina tele, faʻaogaina tele, faʻamamaina ma graphitization, masini ma faia, masani e aofia ai graphite isostatic, graphite faaniukilia, graphite mama maualuga, faʻaaogaina i le aerospace, eletise, vaega o alamanuia faaniukilia.
