E mafai ona faʻaaogaina le kalafi e avea ma penitala, penivali, polesi soʻoga, pe a maeʻa faʻapitoa, e mafai ona faia ni ituaiga mea faʻapitoa, e faʻaaogaina i vaega tau pisinisi. Ma o le a le faʻapitoa faʻaogaina o le graphite efuefu? Lenei o se auiliiliga mo oe.
O le efuefu efuefu e i ai lelei lelei vailaʻau. Maa toner ina ua maeʻa faʻapitoa faʻagaioiga, o loʻo i ai uiga o le lelei faʻaleagaina tetee, lelei conductivity vevela, permeability maualalo, lautele faʻaaogaina i le gaosia o vevela exchanger, tali faʻaali, condenser, afi susunuina, mitiia 'olo, cooler, ea faamafanafana, faamama, pamu masini. Lautele faʻaaogaina i petrochemical, hydrometallurgy, acid ma alkali gaosiaina, gaosia alava, pepa ma isi pisinisi, mafai ona sefe le tele o uamea mea.
Mo lafo, alumini lafoina, suia ma maualuga-vevela metallurgical mea: ona o grafit vevela faʻalautelega coefficient e laiti, ma mafai ona tupu suiga aafiaga vevela, mafai ona faʻaaogaina o se tioata suia, faʻaaogaina graphite uli uʻamea lafo faaiuga lapoʻa, lamolemole luga ma maualuga fua, leai gaosi poʻo sina gaosi mafai ona faʻaaogaina, ina ia sefe ai le tele o uʻamea. O le gaosiga o sima karbida efuefu metallurgy gaioiga, masani lava ona faia mai graphite mea, sintered ma poselane vaʻa. O ogaumu e faʻaola ai Crystal, e pei o le monocrystalline silicon, vaʻaia e faʻamama ai vaʻa, faʻapipiʻi o faʻamau, faʻamama uila, ma isi mea o loʻo faʻatautaia mai le maualuga o le kalafi. I se faʻaopopoga, graphite mafai foi ona faʻaaogaina o lagona gaogao smelting graphite faʻaʻesega laupapa ma faavae, maualuga vevela vevela ogaumu ogaumu, pa, ipu, lattice ma isi vaega.
E mafai foi e le Grafite ona puipuia le faʻapipiʻiina o le faʻapuna, o suʻega o iunite talafeagai e faʻaalia ai, o le faʻaopopoina o le aofaʻi o pauta uʻamea i le vai (e tusa ma le 4 ~ 5 kalama i le tone o le vai) e mafai ona puipuia ai le faʻamamaina o le pupuna luga. I se faʻaopopoga, graphite mafai ona faʻaaogaina i uʻamea chimneys, taualuga, Alalaupapa ma paipa.
I se faʻaopopoga, graphite poʻo tioata ma pepa i malamalama malamalama alamanuia faʻapolopolo ma le poloka inhibitor, o le gaosia o penitala, vaitusi, uliuli vali, vaitusi ma gaosi taimane, taimane taua tele mea mata. O se sili lelei lelei sefeina ma le siosiomaga puipuiga mea, le Iunaite Setete ua faʻaaogaina ia o se taʻavale maa. Faatasi ai ma le atinae o onapo nei faasaienisi ma tekinolosi ma alamanuia, o le faaaogaina o graphite faaauau pea ona faalauteleina, ua avea ma taua taua mea i le maualuga-tekonolosi fanua o fou tuʻufaʻatasia mea, nofoia se taua tulaga i le tamaoaiga o le atunuu.
Faʻaaogaina i le atomika malosi alamanuia ma le atunuʻu puipuiga alamanuia: graphite efuefu e lelei neutron positron faʻaaogaina i atomic reactors, uranium graphite reactor e sili atu faʻaaogaina i le atomic reactor. I le avea ai o le malosiaga faʻaaogaina o le faʻaitiitia o mea mo le faʻaeletise o le reactor, e tatau ona i ai le maualuga o le faʻaliusuaʻiga, mautu ma le pala, ma le graphite efuefu e mafai ona faʻamalieina i luga manaʻoga. Graphite faʻaaogaina i atomic reactors e matua mama aʻiaʻi e le tatau ona sili atu ma le sefulu o vaega i le miliona. Ae maise lava, o le aano o le polone tatau ona laʻititi ifo i le 0.5PPM. I le vaega o puipuiga, o le efuefu efuefu o loʻo faʻaaogaina foi e faia ai ni au mo le mautu-suauʻu roketi, isu o le isu mo fana, vaega mo avanoa vaʻaia meafaigaluega, vevela faʻamamaina, ma radiation puipuiga mea.
