Graphite yotambasuka imapangidwa ndi njira ziwiri

Graphite yotambalala imapangidwa ndi njira ziwiri: mankhwala ndi ma electrochemical. Njira ziwirizi ndizosiyana kuphatikiza pa makutidwe ndi okosijeni, deacidification, kutsuka madzi, kuchepa kwa madzi m'thupi, kuyanika ndi njira zina ndizofanana. Mtundu wazinthu zomwe opanga ambiri amagwiritsa ntchito ndimankhwala amatha kufikira index yomwe ikufotokozedwa mu GB10688-89 "expandable graphite" muyezo, ndikukwaniritsa zofunikira pakupanga mapepala a graphite ambiri komanso mfundo zogulitsa kunja.

Koma kupanga zofunikira zapadera zosakhazikika (≤10%), zotsika zamchere (≤2%) za zinthuzo ndizovuta, njira yopangira siyidutsa. Kulimbikitsa kasamalidwe luso, kuphunzira ndondomeko intercalation mosamala, kumvetsetsa ubale pakati pa magawo ndondomeko ndi ntchito mankhwala, ndi kubala khola khalidwe expandable graphite ndiwo makiyi kusintha mtundu wa mankhwala wotsatira. Qingdao Furuite Graphite chidule: njira yamagetsi yopanda ma oxidants ena, chilengedwe cha flake graphite ndi anode wothandizira palimodzi chimapanga chipinda cha anode choviikidwa mu sulfuric acid electrolyte, kudzera pakadali pano kapena kugunda kwamakono, makutidwe ndi okosijeni patapita nthawi kuti mutulutse, mutatha kutsuka ndi kuyanika graphite yotambalala. Chikhalidwe chachikulu cha njirayi ndikuti magwiridwe antchito a graphite ndi momwe ntchito imagwirira ntchito imatha kuwongoleredwa ndikusintha magawo amagetsi ndi nthawi yochitira, ndikuwononga pang'ono, mtengo wotsika, khola labwino komanso magwiridwe antchito. Ndikofulumira kuthana ndi vuto losakanikirana, kukonza magwiridwe antchito ndi kuchepetsa kugwiritsidwa ntchito kwamagetsi pakuchulukitsa.

Pambuyo podzichotsa pamachitidwe awiriwa pamwambapa, kuchuluka kwa asidi sulfuric kumanyowa ndi kubzala kwa graphite interlamellar mankhwala akadali 1: 1, kugwiritsidwa ntchito kwa othandizira kumakhala kwakukulu, komanso kusamba kwa madzi ndi kutsuka kwa zimbudzi ndizambiri. Ndipo opanga ambiri sanathetse vuto lakumwa kwa madzi ogwiritsira ntchito zonyansa, potulutsa zachilengedwe, kuwononga chilengedwe ndikowopsa, kuletsa chitukuko chamakampani.
