Kusiyana Kofunika Pakati pa Graphitized Petroleum Coke ndi Ordinary Petroleum Coke

1. Kapangidwe ka Atomu: Kusintha kwa Khalidwe Kuchokera ku Chisokonezo kupita ku Dongosolo

• Coke Wamba wa Mafuta: Maatomu a kaboni amakonzedwa mosasunthika kapena motsatira dongosolo lalifupi, mofanana ndi kapangidwe ka kaboni wosasinthika. Ali ndi zolakwika zambiri za lattice, zomwe zimachepetsa mphamvu yake yamagetsi, mphamvu ya kutentha, komanso kukhazikika kwa mankhwala.
• Graphitized Petroleum Coke: Pambuyo pokonza graphitization pa kutentha kwakukulu kwa pafupifupi 3000°C, maatomu a kaboni amakonzedwanso kukhala mawonekedwe a hexagonal layered graphite. Kapangidwe kameneka kali ndi lattice yolimba kwambiri, mphamvu zofooka pakati pa zigawo, komanso kukana kusuntha kwa ma elekitironi kochepa. Kusintha kwa kapangidwe kameneka kumapatsa graphite yachibadwa, monga kuyendetsa magetsi kwambiri, kuyendetsa magetsi kwambiri, komanso kukhazikika kwa mankhwala bwino.

2. Kusiyana kwa Magwiridwe: Kapangidwe kake kamatsimikizira Ntchito

Kuyendetsa Magetsi ndi Kutentha

• Graphitized Petroleum Coke: Kukana kwake kuli kotsika kwambiri kuposa kwa petroleum coke wamba (kungakhale kotsika mpaka 0.001 Ω·m), ndipo kutentha kwake kumakhala kokwera kangapo. Ndikoyenera pazochitika zomwe zili ndi zofunikira kwambiri pamagetsi ndi kutentha (monga zipangizo za anode zamabatire a lithiamu-ion, ma electrode amphamvu kwambiri a graphite).
• Coke ya Mafuta Okhazikika: Chifukwa cha zolakwika m'mapangidwe ake, ili ndi mphamvu yotsika yamagetsi ndipo imagwiritsidwa ntchito kwambiri m'magawo omwe alibe mphamvu yogwira ntchito (monga mafuta, zinthu wamba za kaboni).

Kukhazikika kwa Mankhwala

• Graphitized Petroleum Coke: Kapangidwe kake ka zigawo kamawonjezera kukana kwake ku dzimbiri la mankhwala ochokera ku ma acid, alkali, ndi zina zotero. Sichimawotchedwa kapena kuwonongeka kwambiri kutentha kwambiri, zomwe zimapangitsa kuti ntchito yake ikhale yayitali.
• Coke Wamba wa Petroleum: Umatha kuwonongeka kwambiri m'malo otentha kwambiri kapena owononga, zomwe zimapangitsa kuti magwiridwe antchito awo achepe msanga.

Zinthu Zodetsedwa

• Graphitized Petroleum Coke: Njira yogwiritsira ntchito graphitization ingachepetsenso kuchuluka kwa zinthu zodetsedwa monga sulfure ndi nayitrogeni (kuchuluka kwa sulfure kungachepetsedwe kufika pansi pa 0.1%), kuchepetsa kuipitsa mpweya ndi zotsatirapo zoyipa panthawi yosungunulira (monga ma pores ndi ming'alu mu castings).
• Coke Wamba wa Mafuta: Ili ndi kuchuluka kwa zinthu zodetsedwa ndipo imafuna kukonzedwa pasadakhale (monga calcination) kuti ikwaniritse zosowa za mafakitale ena.

3. Minda Yogwiritsira Ntchito: Kusiyana kwa Magwiridwe Ntchito Kumapangitsa Kusiyanasiyana kwa Kufunikira

Graphitized Petroleum Coke

• Zachitsulo Zapamwamba: Monga chotenthetsera, chimatha kuwonjezera bwino mpweya wa chitsulo chosungunuka ndikuwonjezera mphamvu za chitsulo (monga mphamvu, kulimba), pomwe chimachepetsa kuyambitsa zinthu zovulaza monga sulfure ndi nayitrogeni.
• Zipangizo Zatsopano Zamphamvu: Ndi chinthu chofunikira kwambiri popanga zinthu za anode za mabatire a lithiamu-ion. Mphamvu yake yamagetsi yapamwamba komanso kapangidwe kake ka magawo kumathandiza kukonza mphamvu yamagetsi ndi kutulutsa mphamvu komanso moyo wa mabatire.
• Zinthu Zapadera za Carbon: Zimagwiritsidwa ntchito popanga ma cathode blocks akuluakulu, ma graphitized electrodes, ndi zina zotero, kutengera kuyera kwake kwakukulu, crystallinity yapamwamba, komanso kukana kutentha kwambiri.

Coke ya Mafuta Omwe Amagwiritsidwa Ntchito Pantchito

• Malo Opangira Mafuta: Coke yokhala ndi sulfure yambiri nthawi zambiri imagwiritsidwa ntchito m'mafakitale a simenti, mafakitale agalasi, mafakitale amagetsi, ndi zina zotero, ngati mafuta otsika mtengo.
• Zipangizo Zoyambira za Kaboni: Coke ya sulfure yochepa, pambuyo pa calcination, ingagwiritsidwe ntchito popanga ma anode a electrolysis ya aluminiyamu, ma electrode wamba a graphite, ndi zina zotero, koma magwiridwe ake ndi otsika poyerekeza ndi zinthu zopangidwa ndi graphitized.

4. Njira Yopangira: Kusinthana Pakati pa Kutentha ndi Mtengo

• Coke Wamba wa Mafuta: Amapangidwa kudzera mu njira zochedwetsa kuphika kapena njira zophikira zamadzimadzi, zomwe zimakhala ndi mtengo wotsika. Komabe, zimafunika calcination yowonjezera (pafupifupi 1300°C) kuti zichotse zinthu zosasunthika ndi chinyezi, motero zimawonjezera kuchuluka kwa kaboni kokhazikika.
• Coke ya Petroleum Yopangidwa ndi Graphitized: Pogwiritsa ntchito coke ya petroleum wamba ngati zopangira, imafunika chithandizo china cha graphitization chotentha kwambiri pafupifupi 3000°C. Izi zimawonjezera kwambiri kugwiritsa ntchito mphamvu ndi ndalama zogulira zida, koma chinthucho chili ndi phindu lalikulu.
