Kodi njira yonse yopangira graphitized petroleum coke ndi yotani?

Njira yonse yopangira mafuta a coke okhala ndi graphitized imaphatikiza magawo angapo, kuphatikizapo kukonza zinthu zopangira, calcination, kuphwanya ndi kufufuza, kusakaniza ndi kukanda, kuumba, kuphika, chithandizo cha graphitization, komanso kukonza bwino ndi kulongedza. Nayi mawu oyamba mwatsatanetsatane:

Kuwunika ndi Kukonza Zinthu Zopangira Patsogolo: Zipangizo zapamwamba za petroleum coke carbon zimasankhidwa ndikuwunikiridwa ndi kuphwanyidwa kuti zichepetse kukula kwa tinthu toyenera. Gawoli cholinga chake ndi kuchotsa zonyansa, kuonetsetsa kuti zinthu zopangirazo ndi zoyera komanso kukula kofanana kwa tinthu topangira, potero kukhazikitsa maziko a njira zotsatirazi.

Kukonza Kalisiamu: Zipangizo za petroleum coke carbon za kukula koyenera zimayikidwa mu uvuni wotentha kwambiri kuti zikonze kalisiamu. Njirayi imachotsa chinyezi ndi zinthu zosakhazikika kuchokera kuzinthu zopangira, ndikuwonjezera mphamvu zawo za physicochemical, monga kuchuluka kwenikweni ndi kukana. Kuphatikiza apo, kukonza kalisiamu kumathandizira kuyeretsa ndi kukweza kalisiamu ya petroleum, ndikuwonjezera mphamvu zake zamagetsi ndi mphamvu zake zakuthupi.

Kuphwanya ndi Kuwunika: Pambuyo pa calcination, zotupa za petroleum coke ziyenera kuziziritsidwa kuti zichepetse kutentha kwawo. Pambuyo pake, kukonza makina kumachitika kuti achotse zinthu zosagwirizana ndi zomwe zili, kuonetsetsa kuti zinthuzo zili bwino. Kenako, petroleum coke yoziziritsidwayo imaphwanyidwanso ndi kuwunikiridwa kuti ikwaniritse zofunikira pakugawa tinthu tating'onoting'ono pazochitika zina.

Kusakaniza ndi Kukanda: Malinga ndi zofunikira pakupanga mankhwala, coke ya petroleum yokhala ndi calcium imasakanizidwa ndi chomangira (monga malasha) mu chiŵerengero china. Kenako chisakanizocho chimasakanizidwa pa kutentha kwina kuti zitsimikizire kuti zikugwirizana bwino ndikusakanizidwa kukhala phala losavuta kusakaniza. Gawoli limathandiza kuti chisakanizocho chikhale chopyapyala, ndikupanga phala losavuta kusakaniza lomwe lingathandize kupanga.

Kuumba: Phala la carbonaceous losakanizidwa limasinthidwa ndi pulasitiki chifukwa cha mphamvu yakunja yomwe imagwiritsidwa ntchito ndi zida zoumba, zomwe pamapeto pake zimapangitsa kuti likhale lobiriwira lokhala ndi mawonekedwe, kukula, kuchuluka, ndi mphamvu inayake. Panthawi youmba, zinthu monga mtundu wa nkhungu, kusankha zida, ndi kuwongolera khalidwe la chinthu ziyenera kuganiziridwa kuti zitsimikizire kuti mtundu wa choumba chobiriwiracho ukukwaniritsa zofunikira.

Kuphika: Ma compact obiriwira amaikidwa mu uvuni wotenthetsera wopangidwa mwapadera ndipo amatenthedwa ndi kutentha kwambiri pansi pa chitetezo cha zodzaza zinazake. Njira yophikirayi imapangitsa kuti phula la malasha m'ma compact obiriwira lisinthe kukhala kaboni, ndikupanga pitch coke yomwe imagwirizanitsa carbonaceous aggregate ndi ufa. Zinthu zopangidwa ndi carbon yophikidwayo zimakhala ndi mphamvu zambiri zamakaniko, kukana kotsika, komanso kukhazikika kwabwino kwa kutentha ndi mankhwala.

Chithandizo cha Graphitization: Mabowo a coke ophikidwa a petroleum coke amaikidwa mu uvuni wa graphitization ndipo amachizidwa ndi graphitization kutentha kwambiri (nthawi zambiri 2800℃ -3000℃). Panthawiyi, zonyansa zotsala mu mabowo a coke a petroleum coke zimasinthasintha pang'onopang'ono, pomwe maatomu a kaboni amakonzedwanso kuti apange kapangidwe ka graphite kolimba. Chithandizo cha graphitization chimathandizira kwambiri kuyendetsa magetsi, kuyendetsa kutentha, komanso kukhazikika kwa mankhwala a carbon, zomwe pamapeto pake zimapangitsa kuti coke ya petroleum coke ikhale yoyera kwambiri.

Kukonza ndi Kuyika Zinthu Mopyapyala: Pambuyo pokonza graphitization, petroleum coke imakonzedwa bwino (monga kuyesedwa ndi kuyesedwa) ndi kuyikidwa zinthu mopyapyala isanayambe kugulitsidwa. Zinthuzi zimagwiritsidwa ntchito kwambiri popanga zinthu zosiyanasiyana zamafakitale, kuphatikizapo ma electrode, ma cathode, ndi mafuta a boiler.
