Graphite ine ganda rakatsetsekainoshandiswa zvakanyanya mumaindasitiri, asi kudiwa kwe flake graphite kwakasiyana mumaindasitiri akasiyana, saka flake graphite inoda nzira dzakasiyana dzekuchenesa. Mupepeti anotevera weFuruite graphite achatsanangura nzira dzekuchenesagirafiti yegandaine:
1. Nzira yeHydrofluoric acid.
Zvakanakira zvikuru zve hydrofluoric acid kubvisa tsvina zvakanyanya, giredhi repamusoro rezvigadzirwa, kusakanganisa mashandiro ezvigadzirwa zve graphite uye kushandiswa kwesimba shoma. Dambudziko nderekuti hydrofluoric acid ine chepfu yakawanda uye inoparadza, uye matanho akasimba ekudzivirira kuchengetedzeka anofanirwa kutorwa mukugadzirwa. Zvinodiwa zvakanyanya zvemidziyo zvinotungamirawo pakuwedzera kwemutengo. Pamusoro pezvo, mvura yakasviba inogadzirwa nenzira ye hydrofluoric acid ine chepfu yakawanda uye inoparadza, uye inoda kurapwa kwakasimba isati yaburitswa. Kudyara mari mukuchengetedzwa kwezvakatipoteredza kunoderedzawo zvakanyanya zvakanakira zvemutengo wakaderera we hydrofluoric acid nzira.
2, nzira huru yekuchenesa asidhi.
Kabhoni iri mugrafiti inocheneswa nenzira yealkaline acid inogona kusvika pa99%, iyo ine hunhu hwekudyara mari shoma kamwe chete, giredhi repamusoro rezvigadzirwa uye kugona kuchinjika kwakasimba mukuita. Uyezve, ine zvakanakira zvemidziyo yenguva dzose uye kushanduka kwakasimba. Nzira yekutanga yeasidhi ndiyo nzira inonyanya kushandiswa muChina. Zvakashata zvayo kushandisa simba rakawanda, nguva yakareba yekuita, kurasikirwa negrafiti yakawanda uye kusvibiswa kwakanyanya kwemvura yakasviba.
3. Nzira yekugocha chlorine.
Kupisa kushoma kwekugocha uye kushandiswa kushoma kwechlorine ye chlorination nzira yekugocha zvinoderedza zvakanyanya mutengo wekugadziragirafitiPanguva imwe chete, huwandu hwekabhoni muzvigadzirwa zvegrafiti hwakaenzana nehwekurapwa nehydrofluoric acid, uye mwero wekupora kwenzira yekugocha chlorination wakakwira. Zvisinei, nekuti chlorine ine chepfu uye inoparadza, inoda kushanda nesimba uye inoda kuvharwa zvakasimba, uye gasi remuswe rinofanira kurapwa nemazvo, saka kusvika pamwero wakati, rinoganhurira kufarirwa kwayo uye kushandiswa kwayo.
4. Nzira yekupisa kwakanyanya.
Chinhu chikuru chekushandisa nzira iyi yekupisa kwakanyanya ndechekuti kabhoni iri muchigadzirwa ichi yakakwira zvakanyanya, iyo inogona kusvika pamusoro pe99.995%. Dambudziko nderekuti vira rekupisa kwakanyanya rinofanira kugadzirwa uye kuvakwa, michina yacho inodhura, uye kune mari yakawanda yekudyara. Pamusoro pezvo, kushandiswa kwesimba kwakakwira, uye bhiri remagetsi rakakwira rinowedzera mutengo wekugadzira. Uyezve, mamiriro ekugadzira akaomarara anoitawo kuti kushandiswa kwenzira iyi kuve kushoma zvakanyanya. Mukudzivirira kwenyika, mundege uye mune dzimwe nguva dzine zvinodiwa zvakakosha pakuchena kwezvigadzirwa zvegraphite, nzira iyi inotariswa pakugadzira zvigadzirwa zvidiki zvegirafiti, uye hazvigone kufarirwa mumaindasitiri.
