Cov pa roj carbon dub yog cov nplaim hluav taws kub uas siv dav siv hauv kev lag luam yas thiab roj hmab. Cov pa roj carbon dub muaj qhov zoo ntawm tus nqi qis, kev ua haujlwm siab thiab kev nyab xeeb, thiab tuaj yeem tiv thaiv cov ntaub ntawv yas thiab roj hmab los ntawm kev ntes hluav taws thiab hlawv. Cov pa roj carbon dub kuj tuaj yeem muaj qee qhov tsis zoo ntawm cov nplaim hluav taws.
Cov pa roj carbon dub ua rau cov thermal conductivity ntawm cov yas thiab cov roj hmab. Thermal conductivity yog ib qho qhia ntau ntawm cov khoom siv thermal conductivity. Qhov siab dua qhov thermal conductivity, qhov muaj zog ntawm cov khoom siv thermal conductivity. Ua kom cov thermal conductivity yuav ua rau nws nyuaj rau dissipate tshav kub, yog li ncua lub sij hawm kub hnyiab thiab ua rau txo cov nplaim retardant kev ua tau zoo.
Cov pa roj carbon dub muaj qee qhov dej noo, uas yuav nqus dej noo thiab ua kom cov thermal expansion coefficient ntawm cov yas thiab roj hmab. Thermal expansion coefficient yog qhov ntsuas qhov ntau ntawm qhov hloov pauv ntawm cov khoom thaum lub sijhawm cua sov. Qhov siab dua qhov thermal expansion coefficient, qhov ntau dua cov khoom deformation. Ua kom cov coefficient ntawm thermal expansion tuaj yeem ua rau cov khoom nkig, ua rau lub sij hawm hlawv ntev dua thiab txo cov nplaim hluav taws.
Cov pa roj carbon dub yuav tsim cov pa luam yeeb ntau thiab cov pa phem thaum lub sij hawm combustion, ua rau muaj kev phom sij ntau ntxiv.
Hauv kev siv cov tswv yim, txhawm rau txhim kho cov nplaim hluav taws xob ua haujlwm zoo, nws yog ib qho tsim nyog yuav tsum siv cov pa roj carbon dub zoo thiab tsim nyog txo qhov sib ntxiv. Nyob rau tib lub sijhawm, ntxiv qee cov nplaim hluav taws kub ua haujlwm zoo xws li cov silanes dub thiab pyrogallol Cov nplaim hluav taws kub hnyiab tau tuaj yeem ua kom cov nplaim hluav taws kub hnyiab tau zoo dua thiab txo kev siv cov pa roj carbon dub.
Cov kws tshawb fawb tseem niaj hnub nrhiav cov nplaim hluav taws kub nyhiab ntau dua thiab muaj kev nyab xeeb dua los hloov cov pa roj carbon dub, xws li nplaim hluav taws kub nyhiab raws li cov khoom siv graphene thiab nanocarbon. Cov nplaim hluav taws tshiab no feem ntau muaj qis dua thermal conductivity thiab thermal expansion. coefficient thiab yuav tsis tsim cov pa phem.
Kev siv dav ntawm cov pa roj carbon dub hauv kev lag luam yas thiab roj hmab yog raws li nws cov nplaim hluav taws zoo heev thiab tus nqi qis. Cov pa roj carbon dub kuj muaj qee qhov tsis xws luag, uas muaj qee yam cuam tshuam rau cov nplaim hluav taws. Yog li ntawd, siv cov pa roj carbon dub zoo thiab tsim nyog txo qhov sib ntxiv yog ib txoj hauv kev zoo los txhim kho cov nplaim hluav taws kub. Cov kws tshawb fawb tseem niaj hnub nrhiav cov nplaim hluav taws kub zoo dua thiab nyab xeeb dua los hloov cov pa roj carbon dub, vam tias yuav daws cov teeb meem no thiab ua tiav cov nplaim hluav taws zoo dua.
