Inogona kuwedzera graphite inogadzirwa nemaitiro maviri: kemikari uye electrochemical. Maitiro maviri aya akasiyana mukuwedzera kune iyo oxidation maitiro, deacidification, kushambidza mvura, kupera mvura, kuomesa uye mamwe maitiro akafanana. Hunhu hwezvigadzirwa zvehuwandu hwakawanda hwevagadziri vanoshandisa nzira yemakemikari inogona kusvika kune indekisi yakatarwa muGB10688-89 "expandable graphite" standard, uye inosangana nezvinodiwa zvekugadzirwa kwehuwandu hwakawanda hwachinjeka giraiti grafiti uye zviyero zvekutengesa kunze.
Asi kugadzirwa kwezvakakosha zvinodiwa zvepasi zvisina kugadzikana (≤10%), yakaderera sarufa zvemukati (≤2%) yezvigadzirwa zvakaoma, maitiro ekugadzira haapfuure. Kusimbisa tekinoroji manejimendi, kudzidza iyo intercalation maitiro zvakanyatsonaka, kugona hukama pakati pematanho ekugadzirisa uye kuita kwechigadzirwa, uye kuburitsa yakatsiga mhando inowedzerwa graphite ndiwo makiyi ekuvandudza mhando yezvinotevera zvigadzirwa. Qingdao Furuite Graphite pfupiso: electrochemical nzira isina mamwe maokisheni, iyo yakasarudzika flake graphite uye anobatsira anode pamwechete inoumba anode kamuri yakanyoroveswa mune yakadzika sulfuric acid electrolyte, kuburikidza yakananga ikozvino kana kupomba ikozvino, oxidation mushure meimwe nguva yekutora, mushure mekugeza nekuomesa iri yakawedzera graphite. Hunhu hukuru hwenzira iyi ndeyekuti reaction degree re graphite uye indekisi yekuita kwechigadzirwa inogona kudzorwa nekugadzirisa ma parameter emagetsi uye nguva yekuita, ine kusvibiswa kudiki, mutengo wakaderera, mhando yakatsiga uye kugona kukuru. Izvo zvinokurumidza kugadzirisa dambudziko rekusanganisa, kugadzirisa mashandiro uye kudzikisa kushandiswa kwesimba mune yekuwedzera nzira.
Mushure mekuisirwa deacidification nemaitiro maviri ari pamusoro, huwandu hwehuwandu hwe sulfuric acid kunyorova uye adsorption ye graphite interlamellar makomponi ichiri nezve 1: 1, kushandiswa kweanopindirana mumiririri kwakakura, uye kushambidza kwemvura yekushandisa uye kubuda kweseji kwakakwirira. Uye vazhinji vagadziri havana kugadzirisa dambudziko rekushambidzwa kwemvura yakasviba, mune yakasununguka kubuda, kusvibiswa kwezvakatipoteredza kwakakomba, kuchadzora kusimudzira indasitiri.
