Maitiro ekudzivirira ngura yemidziyo nechinhu chakasimba chinoparadza, kuitira kuderedza mari yekudyara nekugadzirisa michina uye kuvandudza kushanda zvakanaka kwekugadzira uye purofiti idambudziko rakaoma iro mabhizinesi ese emakemikari anofanira kugadzirisa nekusingaperi. Zvigadzirwa zvakawanda zvinodzivirira ngura asi kwete kupisa kwakanyanya, nepo flake graphite ine zvese zvakanakira. Furuite inoteveraGrafitiinosuma zvakadzama kuti flake graphite inogona sei kugadzirisa dambudziko rekuora kwemidziyo:
1. Kufambisa kwekupisa kwakanaka kwazvo.Graphite ine ganda rakatsetsekainewo mafambiro akanaka ekupisa, inova ndiyo yega midziyo isiri yesimbi ine mafambiro ekupisa akakwira kupfuura simbi, ichitanga pakati pemidziyo isiri yesimbi. Mafambiro ekupisa akapetwa kaviri pane simbi yekabhoni uye akapetwa kanomwe pane simbi isina ngura. Saka, yakakodzera michina yekufambisa kupisa.
2. Kudzivirira ngura zvakanyanya. Mhando dzakasiyana dzekabhoni negrafiti dzinodzivirira ngura zvakanyanya pahuwandu hwese hwehydrochloric acid, phosphoric acid nehydrofluoric acid, kusanganisira fluorine-containing media, uye tembiricha yepamusoro inoshandiswa ndeye 350℃-400℃, kureva tembiricha iyo kabhoni negrafiti zvinotanga kuoxida.
3, inodzivirira kupisa kwakanyanya. Kushandiswa kwe flake graphite kunoenderana nemhando yezvinhu zvinoisa mushonga. Semuenzaniso, phenolic graphite inogona kumira 170-200℃, uye kana huwandu hwakakodzera hwe silicone resin graphite yakaisirwa mushonga hukawedzerwa, inogona kumira 350℃. Kana phosphoric acid ikaiswa pa carbon ne graphite, kuramba kwe oxidation kwe carbon ne graphite kunogona kuvandudzwa, uye tembiricha chaiyo yekushanda inogona kuwedzera.
4, pamusoro payo hapasi nyore kugadzika. "Kubatana" kuripo pakati pegrafiti ine flake nemidziyo yakawanda yemagetsi kudiki kwazvo, saka ivhu harina kuoma kunamira pamusoro. Inonyanya kushandiswa mumidziyo ye condensation nemidziyo ye crystallization.
Zvinogona kuonekwa kuti michina ine flake graphite ine simba guru rekudzivirira ngura uye ine hunhu hwepanyama uye hwemakanika, uye inogona kushandiswa kugadzira michina inodzivirira ngura uye yakapararira zvakanyanya muindasitiri yemakemikari.
