Hmoov graphite yog cov khoom siv tsis yog hlau uas muaj cov khoom siv tshuaj lom neeg thiab lub cev zoo heev. Nws yog siv dav hauv kev tsim khoom lag luam. Nws muaj lub ntsiab lus melting siab thiab tuaj yeem tiv taus qhov kub ntawm ntau dua 3000 ° C. Peb yuav ua li cas thiaj paub qhov txawv ntawm lawv qhov zoo ntawm ntau yam hmoov graphite? Tus kws kho graphite Furuite hauv qab no piav qhia txog txoj kev tsim khoom thiab xaiv cov hmoov graphite:
Cov khoom siv tshuaj lom neeg ntawm cov hmoov graphite ntawm chav tsev kub yog qhov ruaj khov, tsis yaj hauv dej, dilute acid, dilute alkali thiab cov kuab tshuaj organic, nrog kev tiv thaiv thermal zoo, tiv thaiv kub siab thiab tiv thaiv corrosion. Hmoov graphite tuaj yeem siv ua cov khoom siv electrode tsis zoo rau cov roj teeb. Cov txheej txheem ntau lawm yog qhov nyuaj heev. Cov hlau nyoos yuav tsum tau tsoo los ntawm lub tshuab tsoo pob zeb, tom qab ntawd ntab los ntawm lub tshuab zeb pob, thiab tom qab ntawd sib tsoo thiab xaiv los ntawm lub tshuab zeb pob. Cov khoom ntub xaiv tau muab ntim rau hauv lub hnab thiab xa mus rau qhov qhuav hauv lub tshuab ziab khaub ncaws. Cov khoom ntub dej tom qab ntawd muab tso rau hauv lub chaw ziab khaub ncaws kom qhuav, thiab nws tau qhuav thiab ntim rau hauv lub hnab, uas yog hmoov graphite ib txwm muaj.
Cov hmoov graphite zoo muaj cov pa roj carbon ntau, qhov nyuaj yog 1-2, kev ua tau zoo dua, zoo, mos, grey tsaus, roj, thiab tuaj yeem ua rau daim ntawv qias neeg. Qhov me me ntawm cov khoom me me, qhov du dua cov khoom ua tiav yuav yog. Txawm li cas los xij, nws tsis yog tias qhov me me ntawm cov khoom me me, qhov zoo dua ntawm cov hmoov graphite. Furuite Graphite ceeb toom txhua tus tias nws yog qhov tseem ceeb kom nrhiav tau cov khoom hmoov graphite zoo uas haum rau koj cov kev xav tau thiab tsim cov nqi ua tau zoo dua.
