Qhov nyiaj graphite txhuam yog txhuam txhuam txhuam uas siv cov khoom siv nyiaj graphite block thiab kuj yog cov khoom siv hlau graphite. Cov pa roj carbon txhuam cov khoom siv tau muab faib ua ntau hom: impregnated graphite, ntshiab graphite, hlau (tooj liab, nyiaj) graphite thiab hluav taws xob graphite. Ua raws li qhov ib puag ncig thiab siv, koj tuaj yeem xaiv cov txhuam txhuam carbon hlau ntawm cov khoom sib txawv thiab qhia peb tias cov kws tsim hluav taws xob tuaj yeem qhia cov pa roj carbon txhuam uas haum koj raws li kev ua haujlwm. Peb tsis tsuas yog muaj cov khoom lag luam tshaj lij tab sis kuj muaj kev pabcuam kev ua haujlwm.
Peb tuaj yeem kho qhov kev tsim khoom raws li cov neeg yuav tsum tau ua.
