Mulingo Wosankha Coke

Ubwino wa petroleum coke makamaka zimadalira mtundu wa zopangira ndi momwe zimapangidwira.Zizindikiro zazikulu zaubwino ndi:

Chiyero
Amatanthauza zomwe zili sulfure ndi phulusa mu petroleum coke.Coke ya sulfure yapamwamba imapangitsa kuti mankhwalawa atukuke panthawi ya graphitization, zomwe zimapangitsa kuti pakhale ming'alu ya carbon.Phulusa lalitali lidzalepheretsa crystallization ya kapangidwe kake ndikukhudza magwiridwe antchito a carbon.

Crystallinity
Amatanthauza kapangidwe ka coke ndi kukula kwa masophase spheres.Coke yopangidwa ndi tizigawo tating'onoting'ono imakhala ndi mawonekedwe a porous monga siponji, ndipo coke yopangidwa ndi zigawo zazikulu imakhala ndi mawonekedwe olimba monga fibrous kapena singano, ndipo khalidwe lake ndi lapamwamba kuposa la sponge coke.Mu index ya khalidwe, kachulukidwe weniweni amaimira ntchito imeneyi, ndipo kachulukidwe kowona kwambiri kumasonyeza kukongola kwa kristalo.

Thermal shock resistance
Kumatanthawuza kukana ming'alu ya zinthu za coke zikagwidwa ndi kutenthedwa kwa kutentha komwe kumakwera mwadzidzidzi kutentha kwambiri kapena kuzizira kwambiri chifukwa cha kutentha kwambiri.Zogulitsa za singano za coke zimakhala ndi kukana kwamphamvu kwamafuta, chifukwa chake zimakhala ndi phindu lalikulu.Coefficient of thermal expansion ikuyimira katundu uyu.Kutsika kwa coefficient ya kukula kwa matenthedwe, kumapangitsa kuti kutentha kukhale bwino.

Ululu
Wachibale zili ufa coke ndi yaikulu granular coke (usable coke) zili mmene coke.Ambiri a ufa coke wathyoledwa ndi zochita mawotchi monga mikangano extrusion mu ndondomeko decoking, yosungirako ndi zoyendera, kotero kuchuluka kwake ndi chiwonetsero cha mphamvu mawotchi.Coke wobiriwira amatha kupewedwa kuti asathyoledwe atapangidwa kuti akhwime.Coke yokhala ndi coke ya granular komanso ufa wocheperako imakhala ndi mtengo wogwiritsa ntchito kwambiri.
