Kuoneka kwa graphite kwatithandiza kwambiri pa moyo wathu. Lero, tiwona mitundu ya graphite, graphite ya nthaka ndi graphite yopyapyala. Pambuyo pofufuza ndi kugwiritsa ntchito kwambiri, mitundu iwiriyi ya zinthu za graphite imagwiritsidwa ntchito kwambiri. Pano, Mkonzi wa Qingdao Furuite Graphite akukuuzani za kusiyana pakati pa mitundu iwiriyi ya graphite:
I. Grafiti ya Flake
Graphite yopangidwa ndi ma crystalline yokhala ndi mamba ndi masamba owonda, mamba akakula, mtengo wake umakhala wapamwamba kwambiri. Ambiri mwa iwo amagawidwa m'miyala. Ili ndi mawonekedwe omveka bwino. Yogwirizana ndi momwe mulingo ulili. Zomwe zili mu graphite nthawi zambiri zimakhala 3% ~ 10%, mpaka kupitirira 20%. Nthawi zambiri imagwirizanitsidwa ndi Shi Ying, feldspar, diopside ndi mchere wina m'miyala yakale ya metamorphic (schist ndi gneiss), ndipo imatha kuwonekanso m'dera lolumikizana pakati pa miyala ya igneous ndi miyala yamwala. Graphite yolimba ili ndi kapangidwe kake, ndipo kukhuthala kwake, kusinthasintha, kukana kutentha ndi kuyendetsa magetsi ndikwabwino kuposa kwa graphite ina. Imagwiritsidwa ntchito makamaka ngati zopangira popanga zinthu za graphite zoyera kwambiri.
II. Grafiti ya nthaka
Graphite yofanana ndi dziko lapansi imatchedwanso amorphous graphite kapena cryptocrystalline graphite. M'mimba mwake wa kristalo wa graphite iyi nthawi zambiri imakhala yochepera 1 micron, ndipo ndi microcrystalline graphite yophatikizidwa, ndipo mawonekedwe a kristalo amatha kuwoneka pokhapokha pogwiritsa ntchito maikulosikopu ya elekitironi. Mtundu uwu wa graphite umadziwika ndi pamwamba pake ngati dothi, kusowa kuwala, mafuta ochepa komanso mtundu wapamwamba. Nthawi zambiri 60 ~ 80%, ochepa mpaka 90%, osasamba bwino ndi miyala.
Kudzera mu kugawana komwe kwatchulidwa pamwambapa, tikudziwa kuti ndikofunikira kusiyanitsa mitundu iwiri ya graphite mu ndondomekoyi, kuti zipangizozo zisankhidwe bwino, zomwe ndizofunikira kwambiri kwa opanga mapulogalamu a graphite.
