He maha nga ahuatanga o te graphite, he aha nga ahuatanga?

Ko te Graphite te hanga o te paura coke me te paura graphite (te pango karauna), i hangaia te bitumen hei wera, a ka mate i te wera nui na te hanga. I runga i nga rauemi mata e whakamahia ana, me te waatea me te wa, ka taea te hanga i nga inihi tika me nga momo tinana me te hangarau. Ko tetahi ahua o te graphite kaha-tiketike, e mohiotia ana ko te graphite karauna, kei te whakaatuhia e tona ngawari me te taiao o te taiao, te iti o te whanaketanga aaanui, me te tukatuka uaua; kei te whakairohia te graphite, ano hoki e mohiotia ana ko te graphite electrochemical.
Ko ona ahuatanga he ngoikore, he iti te kaha me te whaiaro-whaiaro pai. Na te mahinga i te teitei teitei i te wa e mahihia ana te mahinga whakairoiro whakairoiro, ka hurihia te bitumen ki reira hei hanga pores, me te whakaheke i mua i te whakamahinga. Kaore he painga o te graphite ki runga i te whakahaere o te wera, engari kua kaha ake te kaha me te pakeke. I tua atu ki te graphite i whakahuatia i runga nei, kei reira he graphite reini, he mea hanga i te waihanga waikawa hei potae, i konatunatua ki te puehu whakairoiro, i peia me te hanga, a ka wera ake ki te paohana whakaora.
Ko te kaha whakahirahira o te whakairoiro i runga i te rakau ka hangaia ma te whakapiri i nga pungarehu. No te mea ko te kapi he tinana elasto-kirihou, ka whakamahia te piringa tuatoru, ka hangaia te kaha whakaheke, kia kaha haere te kaha o te kaha ki te ara o te aronga axia, me te kaha o te kaha o te kaha ki te whakawhiti ki te mata o te te rakau me te aukati i te rerenga o te reo.
He pai te whaiaro i te whakairoiro graphite, te iti o te whakawhitinga me te kaha o te kaha, me te paanga o te paanga. I te wa e taea ai e te werawera te tu i tetahi waahi, te tangowari ngawari, te ahumahi maatau, nga utu iti.
