Njira zodziwika bwino zopangira graphite yowonjezereka

Graphite yokulirapo ikakonzedwa nthawi yomweyo kutentha kwambiri, kukula kwake kumakhala ngati nyongolotsi, ndipo voliyumu yake imatha kukula nthawi 100-400. Graphite yokulirapo iyi imasungabe mawonekedwe a graphite yachilengedwe, imatha kukula bwino, ndi yomasuka komanso yoboola, ndipo imapirira kutentha pansi pa mikhalidwe yotchinga mpweya. Yosiyanasiyana, imatha kukhala pakati pa -200 ~ 3000 ℃, mawonekedwe a mankhwala amakhala okhazikika pansi pa kutentha kwakukulu, kuthamanga kwambiri kapena kutentha kwambiri, mu kutseka kwamphamvu komanso kosasinthasintha kwa mafakitale amafuta, mankhwala, zamagetsi, ndege, magalimoto, sitima ndi zida Pali mitundu yosiyanasiyana ya ntchito. Okonza otsatirawa a Furuit Graphite adzakuphunzitsani njira zodziwika bwino zopangira graphite yokulirapo:
1. Njira yopangira graphite yotheka kukulitsidwa pogwiritsa ntchito ma ultrasound.
Pokonzekera graphite yowonjezereka, kugwedezeka kwa ultrasound kumachitika pa electrolyte yodzozedwa, ndipo nthawi ya kugwedezeka kwa ultrasound ndi yofanana ndi ya anodization. Popeza kugwedezeka kwa electrolyte ndi mafunde a ultrasonic kumapindulitsa pa polarization ya cathode ndi anode, liwiro la anodic oxidation limakulitsidwa ndipo nthawi ya oxidation imafupikitsidwa;
2. Njira yosungunuka ya mchere imapanga graphite yotheka kufutukuka.
Sakanizani zinthu zingapo zoyikamo ndi graphite ndi kutentha kuti mupange graphite yotheka kufutukuka;
3. Njira yofalitsira mpweya imagwiritsidwa ntchito popanga graphite yotheka kufutukuka.
Graphite ndi zinthu zolumikizidwa pamodzi zimabweretsedwa kumapeto awiri a chubu chotsekedwa ndi vacuum, zimatenthedwa kumapeto kwa zinthu zolumikizidwa pamodzi, ndipo kusiyana kofunikira kwa kuthamanga kwa reaction kumapangidwa ndi kusiyana kwa kutentha pakati pa malekezero awiriwa, kotero kuti zinthu zolumikizidwa pamodzi zimalowa mu flake graphite wosanjikiza ngati mamolekyu ang'onoang'ono, motero graphite yokonzedwa yowonjezereka. Chiwerengero cha zigawo za graphite yowonjezereka yopangidwa ndi njira iyi chikhoza kulamulidwa, koma mtengo wake wopanga ndi wokwera;
4. Njira yolumikizirana ndi mankhwala imapanga graphite yotheka kufutukuka.
Zipangizo zoyamba zomwe zimagwiritsidwa ntchito pokonzekera ndi graphite yokhala ndi mpweya wambiri wa carbon flake, ndipo zinthu zina zoyeretsera monga sulfuric acid yokhazikika (yoposa 98%), hydrogen peroxide (yoposa 28%), potassium permanganate, ndi zina zotero ndi zinthu zoyeretsera za mafakitale. Njira zonse zokonzekera ndi izi: kutentha koyenera, yankho la hydrogen peroxide, graphite yachilengedwe ya flake ndi sulfuric acid yokhazikika yamitundu yosiyanasiyana imayankhidwa kwa nthawi inayake mosakanikirana nthawi zonse ndi njira zosiyanasiyana zowonjezera, kenako imatsukidwa ndi madzi mpaka kusakhala ndi mpweya, ndikuyikidwa mu centrifuge. Pambuyo pochotsa madzi m'thupi, kuumitsa vacuum pa 60 °C;
5. Kupanga graphite yotheka kukulitsidwa pogwiritsa ntchito magetsi.
Ufa wa grafiti umakonzedwa mu electrolyte ya asidi yamphamvu kuti apange graphite yotheka kufutukuka, yothiridwa ndi hydrolyzed, yotsukidwa ndi kuumitsidwa. Popeza asidi yamphamvu, sulfuric acid kapena nitric acid imagwiritsidwa ntchito kwambiri. Grafiti yotheka kufutukuka yomwe imapezeka mwa njira iyi ili ndi sulfure yochepa.
