Umahluko Obalulekileyo Phakathi kweGraphitized Petroleum Coke kunye neOrdinary Petroleum Coke

1. Ulwakhiwo lwe-Atomic Arrangement: Utshintsho oluLungileyo ukusuka kwi-Disorder ukuya kwi-Orderation

• I-Coke yePetroleum eqhelekileyo: Iiathom zekhabhoni zicwangciswe ngendlela engacwangciswanga okanye ekufutshane, efana nesakhiwo sekhabhoni engenasimo. Ineziphene ezininzi ze-lattice, ezithintela ukuhanjiswa kwayo kombane, ukuhanjiswa kobushushu, kunye nokuzinza kweekhemikhali.
• I-Graphitized Petroleum Coke: Emva konyango lwe-graphitization kubushushu obuphezulu obumalunga ne-3000°C, ii-athomu zekhabhoni zihlengahlengiswa zibe yisakhiwo se-graphite esinee-hexagonal layered. Esi sakhiwo sine-lattice ingqibelelo ephezulu, amandla abuthathaka phakathi kwee-layers, kunye nokumelana okuphantsi kokufuduka kwee-electron. Olu tshintsho lwesakhiwo lusinika iipropati eziqhelekileyo ze-graphite, ezifana nokuqhuba umbane okuphezulu, ukuqhuba ubushushu okuphezulu, kunye nokuzinza okugqwesileyo kweekhemikhali.

2. Umahluko ekusebenzeni: Ulwakhiwo luchonga umsebenzi

Ukuqhuba kombane kunye nobushushu

• I-Graphitized Petroleum Coke: Ukumelana kwayo kuphantsi kakhulu kune-petroleum coke eqhelekileyo (inokuba ngaphantsi kwe-0.001 Ω·m), kwaye ukuhanjiswa kwayo kobushushu kuphezulu ngokuphindwe kaninzi. Ifanelekile kwiimeko ezineemfuno ezingqongqo zokuqhuba umbane kunye nobushushu (umz., izixhobo ze-anode zeebhetri ze-lithium-ion, ii-electrode ze-graphite ezinamandla aphezulu).
• I-Ordinary Petroleum Coke: Ngenxa yeziphene zesakhiwo, ayinakho ukuhanjiswa kombane kakuhle kwaye isetyenziswa kakhulu kwiindawo ezineemfuno eziphantsi zokusebenza (umz., ipetroli, izinto zekhabhoni eziqhelekileyo).

Uzinzo lweeKhemikhali

• I-Graphitized Petroleum Coke: Ulwakhiwo lwayo oluneeleya luphucula ukumelana kwayo nokugqwala kweekhemikhali ezivela kwii-asidi, ii-alkali, njl. Ayichaphazeleki kukubola kunye nokubola kumaqondo obushushu aphezulu, nto leyo ebangela ubomi benkonzo obude.
• I-Ordinary Petroleum Coke: Inokuchaphazeleka kakhulu kulwakhiwo kwiindawo ezinobushushu obuphezulu okanye ezingcolisayo, nto leyo ekhokelela ekuwohlokeni kokusebenza ngokukhawuleza.

Umxholo wokungcola

• I-Graphitized Petroleum Coke: Inkqubo ye-graphitization inganciphisa ngakumbi umxholo wokungcola okufana ne-sulfur kunye ne-nitrogen (umxholo we-sulfur ungancitshiswa ube ngaphantsi kwe-0.1%), ukunciphisa ungcoliseko kunye nemiphumo emibi ngexesha lenkqubo yokunyibilikisa (umz., ii-pores kunye nee-cracks kwi-castings).
• I-Ordinary Petroleum Coke: Inomxholo ophezulu wokungcola kwaye ifuna unyango lwangaphambi kokusetyenziswa (umz., i-calcination) ukuze ihlangabezane neemfuno zezinye izicelo zoshishino.

3. IiNdawo zoSetyenziso: Umahluko woKusebenza Ukuqhuba umahluko weemfuno

I-Graphitized Petroleum Coke

• I-Metallurgy yodidi oluphezulu: Njenge-carburizer, inokunyusa ngokufanelekileyo umxholo wekhabhoni wesinyithi esinyibilikisiweyo kwaye iphucule iipropati zesinyithi (umz., amandla, ukuqina), ngelixa inciphisa ukungeniswa kwezinto ezinobungozi ezifana nesalfure kunye ne-nitrogen.
• Izixhobo Ezintsha Zamandla: Sisixhobo esiphambili sezinto ze-anode zeebhetri ze-lithium-ion. Umbane wayo ophezulu kunye nolwakhiwo lwayo oluneeleyara kunceda ukuphucula ukusebenza kakuhle kokukhupha itshaja kunye nobomi bomjikelo weebhetri.
• Iimveliso zeCarbon ezikhethekileyo: Zisetyenziswa ekuveliseni iibhloko ezinkulu ze-cathode, ii-electrode ezine-graphized, njl.njl., zixhomekeke kubunyulu bazo obuphezulu, i-crystallinity ephezulu, kunye nokumelana nobushushu obuphezulu.

I-Coke yePetroleum eqhelekileyo

• Indawo Yokufutha: I-coke ene-sulfur eninzi idla ngokusetyenziswa kwizityalo zesamente, iifektri zeglasi, izikhululo zamandla, njl.njl., njengepetroli engabizi kakhulu.
• Izinto ezisisiseko zeCarbon: I-coke ene-sulfur ephantsi, emva kokuba i-calcination, ingasetyenziswa ekuveliseni ii-anode ze-aluminium electrolysis, ii-electrode ze-graphite eziqhelekileyo, njl.njl., kodwa ukusebenza kwayo kungaphantsi kuneemveliso ze-graphitized.

4. Inkqubo yeMveliso: Utshintsho phakathi kobushushu kunye neendleko

• I-Coke yePetroleum eqhelekileyo: Yenziwa ngokucola okulibazisekileyo okanye iinkqubo zokucola ngolwelo, ngeendleko eziphantsi. Nangona kunjalo, ifuna i-calcination engaphezulu (malunga ne-1300°C) ukususa izinto eziguquguqukayo kunye nokufuma, ngaloo ndlela inyusa umxholo wekhabhoni ozinzileyo.
• I-Graphitized Petroleum Coke: Ukusebenzisa i-petroleum coke eqhelekileyo njengezinto eziluhlaza, kufuna unyango olongezelelweyo lwe-graphitization lobushushu obuphezulu malunga ne-3000°C. Oku kunyusa kakhulu ukusetyenziswa kwamandla kunye neendleko zezixhobo, kodwa imveliso inexabiso elongezelelweyo.
