Cov tsos ntawm graphite tau coj kev pab zoo rau peb lub neej. Niaj hnub no, peb yuav saib cov hom graphite, earthy graphite thiab flake graphite. Tom qab kev tshawb fawb ntau thiab siv, ob hom graphite cov ntaub ntawv no muaj txiaj ntsig zoo siv. Ntawm no, Qingdao Furuite Graphite Editor qhia koj txog qhov sib txawv ntawm ob hom graphite:
I. Flake graphite
Lub crystalline graphite nrog nplai thiab nyias nplooj, qhov loj ntawm cov nplai, qhov nyiaj txiag ntau dua. Lawv feem ntau yog nthuav tawm thiab muab faib rau hauv pob zeb. Nws muaj kev taw qhia pom tseeb. Raws li kev taw qhia ntawm qib. Cov ntsiab lus ntawm graphite feem ntau yog 3% ~ 10%, mus txog ntau tshaj 20%. Nws yog feem ntau txuam nrog Shi Ying, feldspar, diopside thiab lwm yam minerals nyob rau hauv ancient metamorphic pob zeb (schist thiab gneiss), thiab kuj yuav pom nyob rau hauv lub cheeb tsam ntawm igneous pob zeb thiab limestone. Scaly graphite muaj cov txheej txheem txheej, thiab nws lubricity, yooj, kub tsis kam thiab hluav taws xob conductivity zoo dua li lwm cov graphite. Feem ntau yog siv los ua raw khoom rau kev ua cov khoom purity graphite.
II. Earthy graphite
Earthlike graphite tseem hu ua amorphous graphite lossis cryptocrystalline graphite. Cov siv lead ua txoj kab uas hla ntawm cov graphite no feem ntau tsawg dua 1 micron, thiab nws yog ib qho sib xyaw ntawm microcrystalline graphite, thiab cov khoom siv lead ua tuaj yeem pom tsuas yog nyob rau hauv lub tshuab ntsuas hluav taws xob. Hom graphite no yog tus cwj pwm los ntawm nws lub ntiaj teb nto, tsis muaj luster, tsis zoo lubricity thiab qib siab. Feem ntau 60 ~ 80%, ob peb siab li ntau tshaj 90%, tsis zoo ore washability.
Los ntawm kev sib qhia saum toj no, peb paub tias yuav tsum paub qhov txawv ntawm ob hom graphite hauv cov txheej txheem, kom cov ntaub ntawv tuaj yeem xaiv tau zoo dua, uas yog qhov tseem ceeb heev rau graphite daim ntawv thov manufacturers.
