Chiyambi ndi kugwiritsa ntchito graphite yopangira

Graphite yopangidwa ndi polycrystalline yofanana ndi crystallography. Pali mitundu yambiri ya graphite yopangidwa ndi njira zosiyanasiyana zopangira.
Mwachidule, zipangizo zonse za graphite zomwe zimapezeka pambuyo pa carbonization ya zinthu zachilengedwe ndi graphitization pa kutentha kwakukulu zimatha kutchedwa graphite yopangira, monga carbon (graphite) fiber, pyrolytic carbon (graphite), thovu graphite, ndi zina zotero.

M'lingaliro lopapatiza, graphite yopangidwa nthawi zambiri imatanthauza zinthu zolimba kwambiri, monga graphite electrode, isostatic graphite, yopangidwa ndi batching, mixing, molding, carbonization (yomwe imadziwika kuti roasting in industry) ndi graphitization, yokhala ndi zinthu zochepa zodetsedwa za makala (petroleum coke, asphalt coke, etc.) monga aggregate, coal pitch ngati binder.
Pali mitundu yambiri ya graphite yopangira, kuphatikizapo ufa, ulusi ndi chipika, pomwe lingaliro lochepa la graphite yopangira nthawi zambiri limakhala chipika, chomwe chimayenera kukonzedwa kukhala mawonekedwe enaake akagwiritsidwa ntchito. Itha kuonedwa ngati mtundu wa zinthu zambiri, kuphatikiza gawo la graphite losinthidwa ndi tinthu ta kaboni monga petroleum coke kapena asphalt coke, gawo la graphite losinthidwa ndi chomangira cha malasha chophimbidwa mozungulira tinthu tating'onoting'ono, kusonkhanitsa tinthu kapena ma pores opangidwa ndi chomangira cha malasha pambuyo pa chithandizo cha kutentha, ndi zina zotero. Nthawi zambiri, kutentha kwa chithandizo cha kutentha kumakhala kwakukulu, kuchuluka kwa graphitization kumakwera. Kupanga kwa graphite yopangira mafakitale, kuchuluka kwa graphitization nthawi zambiri kumakhala kochepera 90%.

Poyerekeza ndi graphite yachilengedwe, graphite yopangidwa ndi zinthu zakunja imakhala ndi kutentha kochepa komanso mphamvu zamagetsi, mafuta odzola komanso pulasitiki, koma graphite yopangidwa ndi zinthu zakunja imakhala ndi mphamvu yotha kuwononga, kukana dzimbiri komanso kutsika kwa madzi poyerekeza ndi graphite yachilengedwe.

Zipangizo zopangira graphite yopangira zinthu zimaphatikizapo petroleum coke, needle coke, asphalt coke, coal pitch, carbon microspheres, ndi zina zotero. Zogulitsa zake zapansi panthaka zimaphatikizapo graphite electrode, anode yophikidwa kale, isostatic graphite, high purity graphite, nuclear graphite, heat exchanger ndi zina zotero.

Kugwiritsa ntchito graphite yopangira zinthu kumaonekera makamaka m'mbali zotsatirazi:

1. Ma electrode a Graphite: Pogwiritsa ntchito petroleum coke ndi needle coke ngati zinthu zopangira komanso malasha ngati binder, ma electrode a graphite amapangidwa pogwiritsa ntchito calcination, batching, mixing, pressing, roasting, graptitization ndi machining. Amagwiritsidwa ntchito kwambiri mu chitsulo chamagetsi, silicon yamafakitale, phosphorous yachikasu ndi zida zina potulutsa mphamvu yamagetsi mu mawonekedwe a arc kuti itenthe ndikusungunula mphamvu.

2. Anode yophikidwa kale: yopangidwa ndi petroleum coke ngati zopangira ndi malasha ngati chomangira kudzera mu calcination, batching, mixing, pressing, roasting, impregnation, graphitization ndi machining, nthawi zambiri imagwiritsidwa ntchito ngati anode yoyendetsera zida za aluminiyamu zamagetsi.

3. Mphete yotsekera, yotsekera: zida zotumizira zinthu zowononga, graphite yopangidwa ndi mphete za pistoni, mphete zotsekera ndi mabearing, imagwira ntchito popanda kuwonjezera mafuta odzola.

4. Chosinthira kutentha, kalasi yosefera: graphite yochita kupanga ili ndi makhalidwe oletsa dzimbiri, kutentha bwino komanso kutsika kwa mpweya. Imagwiritsidwa ntchito kwambiri mumakampani opanga mankhwala popanga chosinthira kutentha, thanki yoyankhira, choyatsira, chosefera ndi zida zina.

5. Graphite yapadera: yokhala ndi coke yapamwamba kwambiri ya petroleum ngati zopangira, phula la malasha kapena utomoni wopangidwa ngati chomangira, kudzera mu kukonzekera kwa zopangira, kusakaniza, kukanda, kukanikiza, kuphwanya, kusakaniza kukanda, kuumba, kuwotcha kambirimbiri, kulowa kambirimbiri, kuyeretsa ndi graphitization, kukonza ndi kupanga, nthawi zambiri kuphatikiza graphite ya isostatic, graphite ya nyukiliya, graphite yoyera kwambiri, yomwe imagwiritsidwa ntchito mumlengalenga, zamagetsi, ndi mafakitale a nyukiliya.
