Hauv cov roj hmab sib txuas, carbon dub tuaj yeem txhim kho lub cev lub cev, txhim kho thermal stability thiab blackness. Ntau hom thiab ntau npaum li cas ntawm cov pa roj carbon dub yuav muaj qhov sib txawv ntawm cov khoom ntawm cov roj hmab sib xyaw. Kab lus no yuav tsom mus rau qhov tseem ceeb cuam tshuam ntawm cov pa roj carbon dub ntawm cov khoom siv roj hmab.
Qhov loj me me ntawm cov pa roj carbon dub yog ib qho tseem ceeb cuam tshuam rau kev ua haujlwm ntawm cov roj hmab sib txuas. Qhov me me me ntawm cov pa roj carbon dub, qhov zoo dua nws cov dispersion thiab fluidity, yog li lub cev ntawm cov roj hmab compound yuav zoo dua. Particle loj uas me dhau yuav ua rau kom cov viscosity ntawm cov roj hmab sib xyaw thiab cuam tshuam rau nws cov fluidity. Yog li ntawd, nws yog ib qho tseem ceeb los xaiv qhov tsim nyog particle loj.
Thib ob, cov khoom adsorption ntawm carbon dub kuj tseem cuam tshuam rau kev ua haujlwm ntawm cov roj hmab sib xyaw. Cov pa roj carbon dub muaj ntau qhov pores thiab thaj chaw saum npoo, yog li nws muaj peev xwm adsorption siab. Cov cuab yeej adsorption no tuaj yeem txo cov viscosity ntawm cov roj hmab thiab txhim kho cov kua dej, tab sis kuj tseem tuaj yeem ua rau cov roj hmab tsis ruaj khov, yog li nws yuav tsum tau txiav txim siab qhov tsim nyog adsorption khoom ntawm carbon dub.
Thib peb, thermal stability ntawm carbon dub kuj tseem muaj feem cuam tshuam rau kev ua haujlwm ntawm cov roj hmab compound. Cov khoom siv roj hmab feem ntau yuav tsum tau tiv taus qhov kub thiab txias thaum siv. Yog tias cov pa roj carbon dub muaj qhov tsis zoo thermal stability, nws yuav raug kev puas tsuaj, decomposition, oxidation thiab lwm yam tshwm sim nyob rau hauv high-temperature tej yam kev mob, uas ua rau ib tug poob ntawm roj hmab kev ua tau zoo. Yog li ntawd, nws yuav tsum tau siv cov pa roj carbon dub nrog zoo thermal stability.
Thaum kawg, tus nqi ntawm cov pa roj carbon dub ntxiv yuav cuam tshuam rau kev ua haujlwm ntawm cov roj hmab sib xyaw. Txawm hais tias cov pa roj carbon dub tuaj yeem txhim kho lub cev muaj zog, txhim kho thermal stability thiab blackness, yog tias ntxiv ntau dhau, cov roj hmab yuav nplaum thiab nplaum, cuam tshuam rau fluidity, yog li nws yog ib qho tsim nyog yuav tsum tau ntxiv qhov tsim nyog.
Hauv luv luv, qhov cuam tshuam ntawm cov pa roj carbon dub ntawm cov khoom siv roj hmab yog qhov tshwm sim ntawm ntau yam, suav nrog carbon dub particle loj, adsorption zog, thermal stability thiab ntxiv nyiaj. Txhawm rau kom tau txais cov khoom siv roj hmab zoo, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xav txog cov yam ntxwv no thiab xaiv hom thiab tus nqi ntawm cov pa roj carbon dub.
