Maonekedwe a graphite athandiza kwambiri pamoyo wathu. Lero, tiwona mitundu ya graphite, earthy graphite ndi flake graphite. Pambuyo pa kafukufuku wambiri ndikugwiritsa ntchito, mitundu iwiriyi ya zida za graphite imakhala ndi phindu lalikulu. Apa, Qingdao Furuite Graphite Editor akukuuzani za kusiyana kwa mitundu iwiri ya graphite:
I. Flake graphite
Ma crystalline graphite okhala ndi mamba ndi masamba opyapyala, miyeso ikuluikulu, imakhala yokwera mtengo kwambiri. Ambiri aiwo amafalitsidwa ndikugawidwa m'miyala. Ili ndi dongosolo lodziwikiratu. Mogwirizana ndi malangizo a mlingo. Zomwe zili mu graphite nthawi zambiri zimakhala 3% ~ 10%, mpaka 20%. Nthawi zambiri zimagwirizanitsidwa ndi Shi Ying, feldspar, diopside ndi mchere wina m'miyala yakale ya metamorphic (schist ndi gneiss), ndipo imatha kuwonekanso m'malo olumikizana pakati pa miyala yamoto ndi miyala yamchere. Scaly graphite ili ndi mawonekedwe osanjikiza, ndipo kununkhira kwake, kusinthasintha, kukana kutentha ndi madulidwe amagetsi ndiabwino kuposa ma graphite ena. Amagwiritsidwa ntchito makamaka ngati zopangira popanga zinthu zoyera za graphite.
II. graphite yapadziko lapansi
graphite ngati dziko lapansi amatchedwanso amorphous graphite kapena cryptocrystalline graphite. Kutalika kwa kristalo wa graphite iyi nthawi zambiri kumakhala kosakwana 1 micron, ndipo ndi kuphatikiza kwa graphite ya microcrystalline, ndipo mawonekedwe a kristalo amatha kuwoneka pansi pa maikulosikopu ya elekitironi. Mtundu woterewu wa graphite umadziwika ndi nthaka yake yapadziko lapansi, kusowa kwa kuwala, mafuta ochepa komanso apamwamba kwambiri. Nthawi zambiri 60 ~ 80%, ochepa okwera kuposa 90%, ore samachacha bwino.
Kupyolera mu kugawana pamwambapa, tikudziwa kuti ndikofunikira kusiyanitsa mitundu iwiri ya graphite mu ndondomekoyi, kuti zipangizozo zisamalidwe bwino, zomwe ndizofunikira kwambiri kwa opanga mapulogalamu a graphite.
