Ko te kauwhata waihanga he polycrystalline he rite ki te crystallography. He maha nga momo kauwhata horihori me nga tikanga whakaputa rereke.
I roto i te tikanga whanui, ko nga rauemi graphite katoa i whiwhi i muri i te warohanga o te mea waro me te graphitization i te pāmahana teitei ka taea te kiia ko te graphite artificial, penei i te waro (graphite) muka, te waro pyrolytic (graphite), te kauwhata pahuka, etc.
I roto i te tikanga whaiti, graphite horihori te tikanga e pā ana ki te nuinga rauemi totoka, pērā i graphite electrode, graphite isostatic, i hanga e te puranga, te ranu, niao, carbonization (mohiotia rite tunu i roto i te ahumahi) me te graphitization, ki te ihirangi poke iti o waro rauemi mata. (petroleum coke, asphalt coke, etc.) as aggregate, waro pitch as binder.
He maha nga ahua o te graphite artificial, tae atu ki te paura, te muka me te poraka, engari ko te tikanga whaiti o te graphite artificial te nuinga o te poraka, me tukatuka ki tetahi ahua ka whakamahia. Ka taea te kii he momo papanga maha, tae atu ki te wahanga graphite i hurihia e nga matūriki waro penei i te petroleum coke, i te coke asphalt ranei, ko te wahanga graphite i hurihia e te waro waro here i pania huri noa i nga matūriki, te whakaemi matūriki, nga pores ranei i hangaia e te waro. te here i muri i te maimoatanga wera, me etahi atu. Ko te tikanga, ko te teitei ake o te pāmahana maimoatanga wera, ko te teitei ake o te tohu whakairoiro. Ko te hanga ahumahi o te graphite artificial, ko te tohu o te graphitization he iti iho i te 90%.
Ki te whakatauritea ki te kauwhata taiao, he ngoikore te whakawhiti wera me te kawe hiko o te kauwhata horihori, te whakahinuhinu me te kirihou, engari he pai ake te kakahu o te kauwhata horihori, te aukati waikura me te iti o te uruhanga atu i te kauwhata taiao.
Ko nga rauemi mata mo te hanga graphite horihori ko te nuinga o te hinu hinu, te ngira tiihi, te tiihi uku, te waro waro, te microspheres waro, me etahi atu. kaiwhakawhitiwhiti me etahi atu.
Ko te tono hua o te graphite artificial e whakaatuhia ana i roto i nga waahanga e whai ake nei:
1. Graphite electrode: Ma te petroleum coke me te ngira coke hei rauemi mata me te ware waro hei here, ka hangaia te electrode graphite ma te calcination, te puranga, te whakaranu, te pehi, te tunu, te graptitization me te miihini. Kei te whakamahia nuitia i roto i te oumu hiko hiko, te silicon ahumahi, te ūkuikui kowhai me etahi atu taputapu ma te tuku i te hiko hiko i te ahua o te arc ki te wera me te whakarewa i te utu.
2. Anode mua-tunua: hanga o te hinu coke rite rauemi mata me te waro ware hei here i roto i calcination, puranga, ranu, pēhi, tunutunu, impregnation, graphitization me machining, Kei te tikanga whakamahia te reira rite anode conductive o taputapu konumohe electrolytic.
3. Te kawe, te mowhiti hiri: te kawe i nga taputapu pāpāho kino, te graphite artificial e whakamahia ana i nga mowhiti piston, nga mowhiti hiri me nga tohu, mahi me te kore e tapiri hinu hinu.
4. Heat exchanger, tātari akomanga: graphite horihori he nga āhuatanga o te waikura ātete, pai kawe waiariki me te uruhanga iti. Kei te whakamahia nuitia i roto i te ahumahi matū ki te hanga i te whakawhiti wera, te tank tauhohenga, te absorber, te tātari me etahi atu taputapu.
5. Te graphite motuhake: me te kohukohu hinu kounga teitei hei rauemi mata, te waro waro, te kapia waihanga ranei hei here, na roto i te whakarite rauemi mata, te puranga, te pokepoke, te pehi, te kuru, te whakaranu i te pokepoke, te whakakoi, te tunu maha, te kuhu maha, te purenga me te graphitization, te miihini me te hanga, te tikanga tae atu ki te kauwhata isostatic, kauwhata karihi, kauwhata parakore teitei, e whakamahia ana i roto i te mokowhiti, te hikohiko, nga waahanga ahumahi karihi.
