Graphitic Carbon

Graphite hmoov yog ib hom ntxhia hmoov, feem ntau yog tsim los ntawm carbon, mos, dub grey; Greasy, tuaj yeem ua paug rau daim ntawv. Lub hardness yog 1 ~ 2, raws li txoj kab ntsug nrog kev nce ntawm impurities nws hardness tuaj yeem nce mus rau 3 ~ 5. Qhov tshwj xeeb lub ntiajteb txawj nqus yog 1.9 txog 2.3. Nyob rau hauv cov xwm txheej ntawm kev sib cais ntawm cov pa oxygen, nws cov ntsiab lus melting yog siab dua 3000 degree, yog ib qho ntawm cov khoom siv kub-resistant tshaj plaws.

Nyob rau hauv chav tsev kub, cov khoom ntawm graphite hmoov yog qhov ruaj khov, insoluble hauv dej, dilute acid, dilute alkali thiab organic solvents; Cov khoom uas muaj kub conductive zog, yuav siv tau raws li cov ntaub ntawv refractory, cov ntaub ntawv conductive, hnav-resistant lubrication cov ntaub ntawv.

Graphite hmoov yog cov tshuaj rhiab heev. Nyob rau hauv ib puag ncig sib txawv, nws qhov kev tiv thaiv yuav hloov, uas yog, nws tus nqi kuj yuav hloov, tab sis muaj ib yam uas yuav tsis hloov.

Graphite hmoov yog ib qho zoo heev uas tsis yog-hlau conductive tshuaj, tsuav yog cov graphite hmoov nyob rau hauv cov khoom insulating kom ntseeg tau tias tsis muaj kev cuam tshuam, zoo li cov kab nyias nyias yuav muaj zog, txawm li cas los xij, tus nqi tiv thaiv ntau npaum li cas, tus nqi no tsis yog ib qho. yog tus naj npawb, vim tias cov thickness ntawm graphite hmoov, siv nyob rau hauv cov ntaub ntawv sib txawv thiab ib puag ncig graphite hmoov kuj tsis zoo ib yam.
