Muaj ntau lub ntsiab lus thiab impurities sib xyaw hauv cov txheej txheem ntawm ntuj graphite. Cov ntsiab lus carbon ntawm naturalflake graphiteyog hais txog 98%, thiab muaj ntau tshaj 20 lwm yam uas tsis yog-carbon ntsiab, suav txog li 2%. Expanded graphite yog ua tiav los ntawm ntuj flake graphite, yog li yuav muaj qee qhov impurities. Lub hav zoov ntawm impurities muaj ob qho zoo thiab qhov tsis zoo. Cov nram qab no editor ntawm Furuite Graphite yuav piav qhia txog kev cuam tshuam ntawm impurities raunthuav graphite:
1. Qhov zoo ntawm impurities rau nthuav graphite
Cov impurities muaj txiaj ntsig zoo rau cov khoom ntawm nthuav graphite.
2. Kev tsis zoo ntawm impurities ntawm nthuav graphite
Qhov tsis zoo yog tias lub hav zoov ntawm impurities cuam tshuam rau kev nthuav dav zoo ntawmgraphite, thiab tej zaum yuav ua rau kom cov txheej txheem electrochemical corrosion. Yog li ntawd, nyob rau hauv cov txheej txheem ntau lawm ntawm nthuav graphite, nws yog kom meej meej hais tias qhov kev thov rau ntuj flake graphite yuav tsum tau purified.
Furuite graphite ceeb toom rau txhua tus neeg tias cov ntsiab lus impurity coexisting nrog graphite ore tuaj yeem raug tshem tawm yooj yim hauv cov kua qaub thiab ntxuav theem. Cov impurity ntsiab embedded nyob rau hauv nruab nrab ntawm graphite txheej los yog constituting interlayer tebchaw yog decomposed, volatilized los yog nce nyob rau hauv tus txheej txheem ntawm kub kub expansion, thiab hais txog 0.5% ntawm lawv yog oxides thiab silicates. Txawm li cas los xij, lwm cov ntsiab lus tau qhia los ntawm cov kua qaub thiab dej hauv cov txheej txheem tsim khoom.
