Expanded graphite yog xaiv los ntawm cov khoom zoo tshaj plaws ntuj flake graphite li raw khoom, uas muaj lubricity zoo, kub tsis kam, hnav tsis kam thiab corrosion kuj. Tom qab nthuav dav, qhov sib txawv yuav loj dua. Cov nram qab no Furuite graphite editor piav qhia txog kev nthuav dav ntawm graphite nthuav dav:
Expanded graphite yog cov tshuaj tiv thaiv ntawm ntuj flake graphite thiab sib xyaw ntawm cov concentrated nitric acid thiab concentrated sulfuric acid. Vim yog kev nkag mus ntawm cov khoom tshiab, cov tebchaw tshiab yog tsim los ntawm cov graphite txheej, thiab vim yog qhov tsim ntawm cov khoom sib xyaw no, cov txheej txheem graphite yog sib cais los ntawm ib leeg. Thaum lub ntuj graphite uas muaj cov intercalation compound yog raug rau kev kho kub kub, lub ntuj graphite intercalation compound yog sai sai gasified thiab decomposed, thiab lub zog ntawm thawb lub txheej sib nrug ntau dua, thiaj li hais tias lub interlayer ncua sij hawm expands dua, qhov expansion no hu ua lub thib ob expansion, uas yog lub hauv paus ntsiab lus ntawm expansion ntawm nthuav graphite, uas ua rau nthuav graphite.
Expanded graphite muaj kev ua haujlwm ntawm preheating thiab nthuav dav sai, thiab muaj kev ua haujlwm zoo adsorption, yog li nws siv ntau dua hauv cov khoom ntim khoom thiab cov khoom tiv thaiv ib puag ncig adsorption. Lub hauv paus ntsiab lus ntawm expansion graphite yog dab tsi? Qhov tseeb, nws yog qhov kev npaj ntawm nthuav graphite txheej txheem.
