Emva kokuba i-graphite eyandisiweyo iphathwe ngokukhawuleza kwiqondo lokushisa eliphezulu, isikali siba njenge-worm, kwaye umthamo unokwandisa amaxesha angama-100-400. Le graphite yandisiweyo isazigcina iipropathi zegraphite yendalo, inokwandiswa okulungileyo, ikhululekile kwaye i-porous, kwaye iyamelana nobushushu phantsi kweemeko zomqobo weoksijini. Uluhlu olubanzi, lunokuba phakathi kwe-200 ~ 3000 ℃, iipropati zeekhemikhali zizinzile phantsi kobushushu obuphezulu, uxinzelelo oluphezulu okanye iimeko zemitha, ekutywinweni okuguquguqukayo kunye nokutywinwa kwepetroleum, iikhemikhali, umbane, ukuhamba ngeenqwelomoya, iimoto, iinqanawa kunye namashishini ezixhobo. uluhlu olubanzi lwezicelo. Abahleli balandelayo beFuruit Graphite baya kukuthatha ukuba uqonde iindlela zokuvelisa eziqhelekileyo zegraphite eyandiswayo:
1. Indlela ye-Ultrasonic oxidation yokwenza igraphite ekwandiswayo.
Kwinkqubo yokulungiselela i-graphite eyandisiweyo, i-vibration ye-ultrasonic yenziwa kwi-electrolyte anodized, kwaye ixesha lokungcangcazela kwe-ultrasonic lifana ne-anodization. Ekubeni i-vibration ye-electrolyte yi-wave ye-ultrasonic inenzuzo kwi-polarization ye-cathode kunye ne-anode, isantya se-anodic oxidation sikhawuleza kwaye ixesha le-oxidation lifutshane;
2. Indlela yetyuwa etyhidiweyo yenza igraphite eyongezelekayo.
Xuba iifakelo ezininzi kunye negraphite kunye nobushushu ukwenza igraphite eyandiswayo;
3. Indlela ye-gas-phase diffusion isetyenziselwa ukwenza igraphite ekwandiswayo.
Igraphite kunye nezinto ezidityanisiweyo ngokulandelelana ziziswa kwiziphelo ezimbini zetyhubhu etywiniweyo, ishushu ekupheleni kwezinto ezidibeneyo, kwaye umahluko ofunekayo woxinzelelo loxinzelelo lwenziwa ngumahluko wobushushu phakathi kweziphelo zombini, ukuze izinto ezidibeneyo. ingena kumaleko we-flake yegraphite kwimeko yeemolekyuli ezincinci, ngaloo ndlela ILungisa igraphite enwebekayo. Inani leengqimba zegraphite ezandiswayo eziveliswa yile ndlela zinokulawulwa, kodwa iindleko zayo zokuvelisa ziphezulu;
4. Indlela yokudibanisa imichiza yenza igraphite enokwandiswa.
Izinto zokuqala ezisetyenziselwa ukulungiselela i-carbon flake graphite ephezulu, kunye nezinye ii-reagents zekhemikhali ezifana ne-sulfuric acid concentrated (ngaphezu kwe-98%), i-hydrogen peroxide (ngaphezu kwe-28%), i-potassium permanganate, njl. Amanyathelo aqhelekileyo okulungisa zezi zilandelayo: kwiqondo lokushisa elifanelekileyo, isisombululo sehydrogen peroxide, i-graphite yendalo ye-flake kunye ne-sulfuric acid egxininisiweyo yemilinganiselo eyahlukeneyo isabela ixesha elithile phantsi kokuvuselela rhoqo kunye neenkqubo ezahlukeneyo zokongezwa, emva koko ihlanjwe ngamanzi ukuya. ukungathathi hlangothi, kunye ne-centrifuged, Emva kokuphelelwa ngamanzi emzimbeni, ukoma kwe-vacuum kwi-60 °C;
5. Imveliso ye-Electrochemical yegraphite enokwandiswa.
Umgubo wegraphite uphathwa nge-asidi eyomeleleyo ye-electrolyte ukwenza igraphite enokwandiswa, i-hydrolyzed, ihlanjwe kwaye yomiswe. Njenge-asidi eyomeleleyo, i-asidi ye-sulfuric okanye i-nitric acid isetyenziswa kakhulu. Igraphite eyandisiweyo efunyenwe yile ndlela inomxholo ophantsi wesulfure.
