Qhov tshwm sim ntawm graphite tau coj kev pab zoo rau peb lub neej. Niaj hnub no, peb yuav saib cov hom graphite, graphite av thiab flake graphite. Tom qab ntau txoj kev tshawb fawb thiab siv, ob hom graphite no muaj txiaj ntsig zoo. Ntawm no, Qingdao Furuite Graphite Editor qhia koj txog qhov sib txawv ntawm ob hom graphite no:
I. Cov nplais graphite
Cov graphite crystalline nrog cov nplai thiab nplooj nyias, qhov loj dua cov nplai, qhov siab dua tus nqi kev lag luam. Feem ntau ntawm lawv tau nthuav tawm thiab faib rau hauv cov pob zeb. Nws muaj kev teeb tsa pom tseeb. Sib xws nrog kev taw qhia ntawm qib. Cov ntsiab lus ntawm graphite feem ntau yog 3% ~ 10%, txog li ntau dua 20%. Nws feem ntau cuam tshuam nrog Shi Ying, feldspar, diopside thiab lwm yam minerals hauv cov pob zeb metamorphic qub (schist thiab gneiss), thiab kuj tuaj yeem pom hauv thaj chaw sib cuag ntawm cov pob zeb igneous thiab limestone. Scaly graphite muaj cov qauv txheej txheem, thiab nws lubricity, yooj ywm, tiv taus cua sov thiab hluav taws xob conductivity zoo dua li lwm cov graphite. Feem ntau siv ua cov khoom siv raw rau kev ua cov khoom graphite purity siab.
II. Cov graphite av
Cov graphite zoo li lub ntiaj teb no kuj hu ua amorphous graphite lossis cryptocrystalline graphite. Lub diameter ntawm cov graphite no feem ntau tsawg dua 1 micron, thiab nws yog cov graphite microcrystalline sib sau ua ke, thiab cov duab ntawm cov crystal tsuas pom tau hauv qab lub tshuab hluav taws xob xwb. Hom graphite no yog tus cwj pwm los ntawm nws qhov chaw av, tsis muaj qhov ci ntsa iab, tsis muaj roj nplua nyeem thiab qib siab. Feem ntau 60 ~ 80%, qee qhov siab txog ntau dua 90%, tsis yooj yim ntxuav cov hlau.
Los ntawm kev sib qhia saum toj no, peb paub tias nws yog qhov tsim nyog los paub qhov txawv ntawm ob hom graphite hauv cov txheej txheem, yog li cov ntaub ntawv tuaj yeem xaiv tau zoo dua, uas yog qhov tseem ceeb heev rau cov chaw tsim khoom siv graphite.
