Graphite yowonjezereka imapangidwa ndi njira ziwiri: zamankhwala ndi elecclamamical. Njira ziwirizi ndizosiyana kuwonjezera pa njira yotsatsira, kuchotsera, kutsuka kwamadzi, kuchepa madzi, kuwuma ndi njira zina ndizofanana. The quality of the products of the vast majority of manufacturers using chemical method can reach the index stipulated in GB10688-89 “expandable graphite” standard, and meet the material requirements for the production of bulk flexible graphite sheet and export supply standards.
Koma kupanga kwa zofunikira zapadera zotsika (≤10%), zotsika kwambiri za sulufur (≤2%) mwa zinthuzo ndizovuta, njira zopangira sizichitika. Kulimbikitsa kasamalidwe kaukadaulo, kuwerenga njira yolumikizirana mosamala, kuphunzitsira mgwirizano pakati pa magawo ndi magwiridwe antchito, ndikupanga graphite yokhazikika ndi makiyi opangira zomwe zimapangitsa kuti pakhalenso zinthu zina. Quingdao Fumboin Plafiiite Chidule: Njira ya Ectochem popanda oxidants, chilengedwe chokhala ndi malo ovomerezeka a ad electrolyte, kudzera pa nthawi yayitali, oxidation pambuyo poti atulutse ndi kuyanika ndikosambitsa. Khalidwe lalikulu la njirayi ndikuti kuchuluka kwa chojambulachi ndi mndandanda wazomwezo zitha kuwongoleredwa ndikusintha magawo a magetsi ndi nthawi yovuta, mtengo wotsika komanso ntchito yabwino komanso yokhazikika. Ndikofunikira kuti athetse vuto losakanikirana, sinthani bwino ntchitoyo ndikuchepetsa kugwiritsa ntchito mphamvu munthawi yogawana.
Pambuyo pochotsa njira ziwiri pamwambapa, kuchuluka kwa misa ya sulfuric acid kunyowa ndi adsorption ya ma graphite intergmel and 1: 1, kugwiritsidwa ntchito kwa othandizira ndi akuluakulu, ndipo zotumphuka zamadzi ndizokwera. Ndipo ambiri opanga sanathetse vuto la chithandizo chamadzimadzi, munthawi ya kuwonongeka kwachilengedwe, kuwonongeka kwa chilengedwe ndikofunikira, kumaletsa kukula kwa mafakitale.
