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 ne-static ye-petroleum, iikhemikhali, umbane, i-aviation, i-automobile, inqanawa kunye ne-instrumentation amashishini Kukho 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 intercalated ngokulandelelana zisiwe kwiziphelo ezimbini vacuum etywiniweyo ityhubhu, ishushu ekupheleni izinto intercalated, kwaye umahluko oluyimfuneko reaction loxinzelelo lwenziwa ngumahluko lobushushu phakathi kweziphelo ezimbini, ukuze izinto intercalated ingena kwiflake igraphite umaleko kwimo yeemolekyuli ezincinci, ngaloo ndlela Ilungiselelwe igraphite eyandisiweyo. 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 okulungiselela ami ngolu hlobo lulandelayo: kwiqondo lokushisa elifanelekileyo, isisombululo se-hydrogen 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 ukungathathi hlangothi, kunye ne-centrifuged, Emva kokuphelelwa ngamanzi emzimbeni, i-vacuum drying 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.
