Muaj ntau yam khoom thiab cov khoom tsis huv sib xyaw ua ke hauv cov txheej txheem sib xyaw ntawm cov graphite ntuj. Cov ntsiab lus carbon ntawm cov graphite ntujgraphite flakeyog li ntawm 98%, thiab muaj ntau tshaj 20 lwm yam khoom tsis yog carbon, suav txog li 2%. Cov graphite nthuav dav yog ua los ntawm cov flake graphite ntuj, yog li yuav muaj qee qhov tsis huv. Qhov muaj cov tsis huv muaj ob qho zoo thiab qhov tsis zoo. Tus editor hauv qab no ntawm Furuite Graphite yuav piav qhia txog kev cuam tshuam ntawm cov tsis huv raunthuav dav graphite:
1. Cov txiaj ntsig ntawm cov khoom tsis huv rau cov graphite nthuav dav
Cov khoom tsis huv muaj txiaj ntsig zoo rau cov khoom ntawm cov graphite nthuav dav.
2. Cov yam tsis zoo ntawm cov khoom tsis huv ntawm cov graphite nthuav dav
Qhov tsis zoo yog tias qhov muaj cov khoom tsis huv cuam tshuam rau qhov zoo ntawm kev nthuav dav ntawmgraphite, thiab tej zaum yuav ua rau cov txheej txheem xeb electrochemical nce ntxiv. Yog li ntawd, hauv cov txheej txheem tsim cov graphite nthuav dav, nws tau teev meej meej tias qhov kev thov rau cov flake graphite ntuj yuav tsum tau purified.
Furuite graphite ceeb toom rau txhua tus neeg tias cov khoom tsis huv uas nyob ua ke nrog graphite ore tuaj yeem raug tshem tawm yooj yim hauv kev kho acid thiab kev ntxuav theem. Cov khoom tsis huv uas nyob hauv nruab nrab ntawm graphite txheej lossis cov khoom sib xyaw ua ke yog decomposed, volatilized lossis nce ntxiv hauv cov txheej txheem ntawm kev nthuav dav kub siab, thiab kwv yees li 0.5% ntawm lawv yog oxides thiab silicates. Txawm li cas los xij, lwm cov ntsiab lus yog qhia los ntawm acid thiab dej hauv cov txheej txheem ntau lawm.
