Cov graphite nthuav dav yog xaiv los ntawm cov khoom siv zoo flake graphite ua cov khoom siv raw, uas muaj lubricity zoo, tiv taus kub siab, hnav tsis kam thiab tiv taus corrosion. Tom qab nthuav dav, qhov sib txawv loj dua. Cov kws kho graphite Furuite hauv qab no piav qhia txog txoj cai nthuav dav ntawm cov graphite nthuav dav:
Cov graphite uas nthuav dav yog ib qho kev sib xyaw ntawm cov flake graphite ntuj thiab cov sib xyaw ntawm cov kua qaub nitric thiab cov kua qaub sulfuric uas muaj zog. Vim muaj cov tshuaj tshiab nkag los, cov tshuaj tshiab tau tsim ntawm cov txheej graphite, thiab vim muaj cov tshuaj no, cov txheej graphite ntuj tau sib cais ntawm ib leeg. Thaum cov graphite ntuj uas muaj cov tshuaj sib xyaw ua ke raug kho kom sov siab, cov tshuaj graphite ntuj tau ua pa sai sai thiab lwj, thiab lub zog ntawm kev thawb cov txheej sib nrug ntau dua, yog li ntawd qhov sib nrug ntawm cov txheej nthuav dav dua. Qhov kev nthuav dav no hu ua qhov kev nthuav dav thib ob, uas yog lub hauv paus ntsiab lus ntawm kev nthuav dav ntawm cov graphite nthuav dav, uas ua rau cov graphite nthuav dav.
Cov graphite nthuav dav muaj lub luag haujlwm ntawm kev ua kom sov ua ntej thiab nthuav dav sai, thiab muaj lub luag haujlwm adsorption zoo, yog li nws siv ntau dua hauv cov khoom foob thiab cov khoom tiv thaiv ib puag ncig adsorption. Lub hauv paus ntsiab lus ntawm kev nthuav dav ntawm cov graphite nthuav dav yog dab tsi? Qhov tseeb, nws yog kev npaj cov txheej txheem graphite nthuav dav.
