Kapangidwe kabwino ka mankhwala a graphite

Graphite yachilengedweZingagawidwe m'magulu a crystalline graphite ndi cryptocrystalline graphite. Crystalline graphite, yomwe imadziwikanso kuti scaly graphite, ndi scaly ndi flaky crystalline graphite. Scally graphite ikakhala yayikulu, mtengo wake umakhala wapamwamba kwambiri. Kapangidwe ka mafuta a injini ya flake graphite kamakhala ndi mafuta abwino, kufewa, kukana kutentha komanso kuyendetsa magetsi kuposa ma graphite ena, ndipo amapangidwa makamaka ndi zinthu zopangira graphite zoyera kwambiri. Mkonzi wotsatira wa Furuite Graphite akuwonetsa mphamvu zabwino kwambiri za graphite yabwino kwambiri:

Graphite ya flake ndi yofanana ndi flake, yopyapyala ngati tsamba loyeragraphite, yokhala ndi kukula kwa (1.0 ~ 2.0) × (0.5 ~ 1.0) mm, makulidwe a 4 ~ 5 mm ndi makulidwe a 0.02 ~ 0.05 mm.. Chiyeso chikakhala chachikulu, mtengo wake wachuma umakwera. Ambiri mwa iwo amafalikira ndipo amafalikira ngati hemp m'miyala, yokhala ndi mawonekedwe omveka bwino, omwe amagwirizana ndi komwe kuli bedi. Kuchuluka kwa graphite ya flake nthawi zambiri kumakhala 3% ~ 10%, ndi kutalika kopitilira 20%. Nthawi zambiri imagwirizanitsidwa ndi mchere monga Shi Ying, feldspar ndi diopside m'miyala yakale ya metamorphic (schist ndi gneiss), ndipo imatha kuwonekanso pamalo olumikizirana pakati pa miyala ya igneous ndi miyala yamwala. Graphite ya scaly ili ndi kapangidwe ka magawo, ndipo kukhuthala kwake, kusinthasintha, kukana kutentha ndi kuyendetsa magetsi ndikwabwino kuposa kwa ma graphite ena. Imagwiritsidwa ntchito makamaka ngati zopangira zopangira zinthu za graphite zoyera kwambiri.

Malinga ndi kuchuluka kwa kaboni kokhazikika, graphite ya flake ingagawidwe m'magulu anayi: graphite yoyera kwambiri, carbon yambirigraphite, graphite yapakati pa kaboni ndi graphite ya kaboni yochepa. Graphite yoyera kwambiri imagwiritsidwa ntchito makamaka ngati zinthu zotsekera graphite m'malo mwa platinum crucible yopangira mankhwala osungunula ndi zinthu zodzoladzola. Graphite ya kaboni yambiri imagwiritsidwa ntchito makamaka mu refractories, zinthu zodzoladzola, zinthu zopangira burashi, zinthu zamagetsi za kaboni, zinthu zopangira batri ndi zina zotero. Graphite yapakati pa kaboni imagwiritsidwa ntchito makamaka mu zodzoladzola, zodzoladzola, zinthu zopangira, zophimba, zophimba, zophimba, zophimba, zinthu zopangira mapensulo, zinthu zopangira batri ndi mafuta. Graphite ya kaboni yochepa imagwiritsidwa ntchito makamaka popangira zophimba.
