1. Cov graphite uas nthuav tau tuaj yeem txhim kho qhov kub ntawm cov khoom siv hluav taws kub.
Hauv kev tsim khoom lag luam, txoj kev siv feem ntau yog ntxiv cov tshuaj tua hluav taws rau hauv cov yas engineering, tab sis vim qhov kub qis ntawm kev lwj, kev lwj yuav tshwm sim ua ntej, ua rau tsis ua haujlwm. Cov khoom siv lub cev ntawm cov graphite nthuav dav yog ruaj khov, uas yuav tsis cuam tshuam rau qhov zoo ntawm cov khoom siv ua tiav thiab txhim kho cov khoom tua hluav taws.
Cov txiaj ntsig ntawm cov graphite nthuav dav yog dab tsi?
Cov graphite nthuav tau
2. Cov pa luam yeeb uas tsim los ntawm cov graphite nthuav dav tsawg dua thiab cov nyhuv tseem ceeb.
Feem ntau hais lus, cov tshuaj halogenated flame retardants yuav raug ntxiv rau hauv kom ua rau cov khoom ua haujlwm tiv thaiv hluav taws thiab tiv thaiv hluav taws, tab sis yuav tsim cov pa luam yeeb thiab cov pa roj acid, cuam tshuam rau tib neeg kev noj qab haus huv, xeb ntawm cov khoom siv hauv tsev; Hlau hydroxide kuj tseem yuav raug ntxiv rau hauv, tab sis nws muaj kev cuam tshuam loj heev rau kev tiv thaiv kev cuam tshuam thiab lub zog kho tshuab ntawm cov yas lossis matrix, thiab kuj tuaj yeem cuam tshuam rau tib neeg txoj kev noj qab haus huv thiab ua rau cov khoom siv hauv tsev xeb. Thaum huab cua tsis du heev, kev ntxiv cov tshuaj phosphorous flame retardants tuaj yeem muaj kev cuam tshuam loj rau tib neeg. Expandable graphite yog qhov zoo tagnrho. Nws tsim cov pa luam yeeb me me thiab muaj cov nyhuv tiv thaiv hluav taws tseem ceeb.
3. Cov graphite uas nthuav tau muaj kev rwb thaiv cua sov zoo thiab tiv taus xeb.
Graphite uas nthuav tau yog ib yam khoom uas tiv taus xeb thiab muaj nyob ua ib lub siv lead ua ruaj khov. Nws tsis lwj thaum lub sijhawm lwj thiab oxidation kom txog thaum nws puas vim muaj kev txwv ntawm lub sijhawm khaws cia thiab kev ruaj khov.
Hauv kev xaus lus, qhov zoo ntawm cov graphite nthuav dav ua rau nws yog cov khoom siv xaiv rau kev rwb thaiv tsev kub thiab tiv thaiv hluav taws. Thaum xaiv cov graphite nthuav dav, peb yuav tsum xaiv cov khoom graphite nthuav dav zoo kom ua tiav cov txiaj ntsig kev lag luam, tsis yog rau tus nqi qis xwb.
