Kodi kapangidwe kake kakang'ono (kapangidwe ka kristalo) ka graphitized petroleum coke kali bwanji?

I. Makhalidwe a Kapangidwe ka Crystal

Kapangidwe ka Zigawo: Kapangidwe ka kristalo ka graphitized petroleum coke kamakhala ndi maukonde ozungulira a maatomu a kaboni a hexagonal. Maukonde ozungulira awa amakhala olumikizidwa ndi zigawo, ndikupanga kapangidwe kabwino ka zigawo. Zigawozo zimalumikizidwa ndi mphamvu zofooka za van der Waals, zomwe zimapatsa graphite mafuta ndi anisotropy.
Zokhazikika pa Lattice: Pambuyo pa chithandizo cha graphitization, zokhazikika pa lattice (a₀ ndi c₀) za petroleum coke zimayandikira za graphite yachilengedwe, zomwe zimasonyeza kufanana kwakukulu m'mapangidwe awo a kristalo. Kapangidwe kameneka kamathandiza kuti petroleum coke yokhala ndi graphit iwonetse bwino kwambiri magetsi ndi kutentha.
Ma Parameter a Microcrystalline: Pogwiritsa ntchito X-ray diffraction, magawo monga interlayer spacing (d₀₀₂), average layer diameter (Lₐ), ndi stacking height (Lc) ya ma microcrystals mu graphitized petroleum coke amatha kuwerengedwa. Ma parameter awa amawonetsa kukula ndi kapangidwe ka ma microcrystals ndipo amagwira ntchito ngati zizindikiro zofunika poyesa kuchuluka kwa graphitization.

II. Zotsatira za Njira Yopangira Zithunzi

Kusintha kuchokera ku Amorphous kupita ku Crystalline State: Asanayambe graphitization, kapangidwe ka kaboni ka petroleum coke kamakhala kopanda mawonekedwe, komwe kamadziwika ndi kapangidwe ka zinthu "kopanda mawonekedwe akutali, kolamulidwa ndi nthawi yochepa". Kudzera mu graphitization therapy (nthawi zambiri kumachitika kutentha kwakukulu kuyambira 2500°C mpaka 3000°C), kaboni wosasinthika pang'onopang'ono umasintha kukhala kapangidwe ka kristalo ka graphite kolamulidwa ndi magawo atatu.
Kuwonjezeka kwa Kukula kwa Microcrystallite: Panthawi ya graphitization, makulidwe apakati (Lc) ndi m'lifupi (Lₐ) a carbon lattice flakes amawonjezeka, pomwe mtunda wa pakati pa zigawo (d) umachepa. Izi zimapangitsa kuti kukula kwa microcrystallite kuchuluke komanso kapangidwe kabwino kwambiri ka kristalo.
Kuchepa kwa Kukana: Pamene kuchuluka kwa graphitization kukuwonjezeka, kukana kwa graphitized petroleum coke kumachepa kwambiri. Izi zili choncho chifukwa, panthawi ya graphitization, makonzedwe a maatomu a kaboni amakhala okonzedwa bwino, zomwe zimathandiza kuti ma elekitironi aziyenda momasuka mkati mwa zigawo, motero kumawonjezera mphamvu zamagetsi.

III. Ubale Pakati pa Kapangidwe Kakang'ono ndi Katundu

Kuyendetsa Magetsi: Kapangidwe ka galasi ka graphitized petroleum coke kamathandiza ma elekitironi kuyenda momasuka mkati mwa zigawo, zomwe zimapangitsa kuti magetsi aziyenda bwino kwambiri. Kapangidwe kameneka kamapangitsa kuti graphitized petroleum coke igwiritsidwe ntchito kwambiri m'malo monga zipangizo zama electrode ndi zowonjezera zoyendetsera magetsi.
Kuyendetsa Matenthedwe: Chifukwa cha mphamvu za van der Waals zomwe zimalumikiza zigawo, kutentha kumatha kusamutsidwa mwachangu mkati mwa zigawozo. Chifukwa chake, petroleum coke yokhala ndi graphitized imakhalanso ndi kuyendetsa bwino kutentha, zomwe zimapangitsa kuti ikhale yoyenera kupanga zinthu zotenthetsera kutentha ndi ntchito zina.
Kapangidwe ka Makina: Kapangidwe ka kristalo ka graphitized petroleum coke kamapatsa mphamvu inayake yamakina. Komabe, poyerekeza ndi zinthu zachitsulo, kapangidwe kake ka zigawo zimapangitsa kuti pakhale mgwirizano wofooka pakati pa zigawo, zomwe zimapangitsa kuti pakhale mphamvu zochepa zopindika komanso zopondereza. Khalidweli limapatsa graphitized petroleum coke mwayi wogwiritsidwa ntchito pazochitika zomwe zimafunika kupirira kupsinjika kwina koma sizimafuna mphamvu zambiri.
