Ngemuva kokuthi i-graphite enwebekayo iphathwe ngokushesha ekushiseni okuphezulu, isikali siba njenge-worm, futhi umthamo ungakhula izikhathi ezingu-100-400. Le graphite eyandisiwe isalondoloza izici zegraphite yemvelo, inokunwebeka okuhle, ayikhululekile futhi inezimbotshana, futhi imelana nezinga lokushisa ngaphansi kwezimo zokuvimbela umoya-mpilo. Ububanzi obubanzi, bungaba phakathi -200 ~ 3000 ℃, izakhiwo zamakhemikhali zizinzile ngaphansi kwezinga lokushisa eliphezulu, ingcindezi ephezulu noma izimo zemisebe, ekubekweni uphawu okuguquguqukayo nokumile kwe-petroleum, amakhemikhali, ugesi, izindiza, izimoto, umkhumbi kanye nezimboni zezinsimbi. anhlobonhlobo izicelo. Abahleli abalandelayo be-Furuit Graphite bazokusa ukuze uqonde izindlela ezivamile zokukhiqiza zegraphite enwebekayo:
1. Indlela ye-Ultrasonic oxidation yokwenza igraphite enwebekayo.
Enqubweni yokulungiselela i-graphite enwebekayo, ukudlidliza kwe-ultrasonic kwenziwa ku-electrolyte e-anodized, futhi isikhathi sokudlidliza kwe-ultrasonic siyefana neso-anodization. Njengoba ukudlidliza kwe-electrolyte nge-wave ye-ultrasonic kunenzuzo ku-polarization ye-cathode kanye ne-anode, isivinini se-anodic oxidation siyasheshisa futhi isikhathi se-oxidation sifushane;
2. Indlela kasawoti encibilikisiwe yenza igraphite enwebekayo.
Hlanganisa ukufakwa okuningana nge-graphite nokushisa ukuze wenze i-graphite enwebekayo;
3. Indlela ye-gas-phase diffusion isetshenziselwa ukwenza igraphite enwebekayo.
I-graphite nezinto ezixhumene ngokulandelana zilethwa emikhawulweni emibili yeshubhu elivalwe nge-vacuum, lishisiswe ekugcineni kwento ehlanganisiwe, futhi umehluko odingekayo wengcindezi yokusabela wakhiwa umehluko wokushisa phakathi kweziphetho ezimbili, ukuze impahla ehlanganisiwe. ingena ongqimbeni lwe-flake lwe-graphite esimweni sama-molecule amancane, ngaleyo ndlela Ilungiselelwe igraphite enwebekayo. Inani lezingqimba zegraphite ezinwebekayo ezikhiqizwa yile ndlela zingalawulwa, kodwa izindleko zayo zokukhiqiza ziphezulu;
4. Indlela yokuhlanganisa amakhemikhali yenza igraphite enwebekayo.
Impahla yokuqala eluhlaza esetshenziselwa ukulungiswa iphezulu i-carbon flake graphite, namanye ama-reagents amakhemikhali afana ne-concentrated sulfuric acid (ngaphezu kuka-98%), i-hydrogen peroxide (ngaphezu kuka-28%), i-potassium permanganate, njll. Izinyathelo ezijwayelekile zokulungiselela zimi kanje: ekushiseni okufanelekile, isisombululo se-hydrogen peroxide, i-flake yemvelo ye-graphite kanye ne-sulfuric acid egxilile yezilinganiso ezihlukene zisabela isikhathi esithile ngaphansi kokugqugquzelwa njalo ngezinqubo zokwengeza ezihlukene, bese zigezwa ngamanzi ukuze ukungathathi hlangothi, kanye ne-centrifuged, Ngemva kokuphelelwa amanzi emzimbeni, i-vacuum drying ku-60 °C;
5. Ukukhiqizwa kwe-electrochemical yegraphite enwebekayo.
I-graphite powder iphathwa nge-acid electrolyte eqinile ukwenza igraphite enwebekayo, i-hydrolyzed, igezwe futhi yomiswe. Njenge-asidi eqinile, i-sulfuric acid noma i-nitric acid isetshenziswa kakhulu. I-graphite enwebekayo etholwe yile ndlela inokuqukethwe okuphansi kwesibabule.
