Mushure mekunge graphite inokura yagadziriswa ipapo ipapo pakupisa kwakanyanya, chikero chinova sehonye, uye huwandu hunogona kuwedzera ka100-400. Iyi graphite inokura ichiri kuchengetedza hunhu hwegirafiti yechisikigo, inogona kukura zvakanaka, haina kuzara uye ine maburi, uye inodzivirira tembiricha pasi pemamiriro ekudzivirira okisijeni. Yakasiyana-siyana, inogona kuva pakati pe -200 ~ 3000 ℃, hunhu hwemakemikari hwakagadzikana pasi pekupisa kwakanyanya, kumanikidzwa kwakanyanya kana mamiriro emwaranzi, mukushandiswa kwesimba uye kusingachinji kwemafuta epetroleum, makemikari, magetsi, ndege, mota, ngarava nemidziyo. Kune akawanda mashandisirwo. Vanyori veFuruit Graphite vanotevera vachakutora kuti unzwisise nzira dzakajairika dzekugadzira girafiti inokura:
1. Nzira ye ultrasonic oxidation yekugadzira graphite inokura.
Mukugadzirira graphite inowedzerwa, kutenderera kwe ultrasonic kunoitwa pa electrolyte inozorwa, uye nguva yekutenderera kwe ultrasonic yakafanana neye anodization. Sezvo kutenderera kwe electrolyte ne ultrasonic wave kuchibatsira pakutenderera kwe cathode ne anode, kumhanya kwe anodic oxidation kunowedzera uye nguva ye oxidation inopfupikiswa;
2. Nzira yemunyu wakanyungudutswa inoita kuti girafiti ikwanise kukura.
Sanganisa zvinhu zvakasiyana-siyana zvinoiswa negrafiti uye kupisa kuti zvigadzire girafiti inokura;
3. Nzira yekupararira kwegasi inoshandiswa kugadzira girafiti inogowedzera.
Graphite nezvinhu zvakabatana zvinounzwa kumagumo maviri echubhu yakavharwa ne vacuum, zvichidziiswa kumagumo echinhu chakabatana, uye musiyano wekumanikidzwa kwekuita unodiwa unoumbwa nemusiyano wekupisa pakati pemativi maviri, kuitira kuti zvinhu zvakabatana zvipinde muchikamu chegraphite chakapfava mumamiriro emamorekuru madiki, nokudaro giraphite inowedzerwa yakagadzirwa. Huwandu hwezvikamu zvegraphite inowedzerwa inogadzirwa nenzira iyi hunogona kudzorwa, asi mutengo wayo wekugadzira wakakwira;
4. Nzira yekubatanidza makemikari inoita kuti girafiti ikwanise kuwedzeredzwa.
Chinhu chekutanga chinoshandiswa pakugadzira igrafiti ine kabhoni yakawanda, uye mamwe ma reagents emakemikari akadai se sulfuric acid yakakangwa (inopfuura 98%), hydrogen peroxide (inopfuura 28%), potassium permanganate, nezvimwewo zvese ma reagents emhando yeindasitiri. Matanho akajairika ekugadzirira ndeaya anotevera: patembiricha yakakodzera, hydrogen peroxide solution, natural flake graphite uye sulfuric acid yakakangwa yehuwandu hwakasiyana zvinogadziriswa kwenguva yakati zvichikurunga nguva dzose nenzira dzakasiyana dzekuwedzera, zvozogezwa nemvura kusvika yanyatsopinda, uye zvinoiswa mukati me centrifuge. Mushure mekushaya mvura, kuomesa ne vacuum pa60 °C;
5. Kugadzirwa kwegirafiti inokura nemagetsi.
Upfu hwegirafiti hunorapwa ne electrolyte ine acid yakasimba kuti igadzire girafiti inokura, inonyungudutswa, inogezwa uye inoomeswa. Sezvo strong acid, sulfuric acid kana nitric acid ndiyo inonyanya kushandiswa. Graphite inokura inowanikwa nenzira iyi ine sarufa shoma.
