Yuav kom tiv thaiv tau qhov kev puas tsuaj ntawm corrosion los ntawm oxidation ntawm flake graphite ntawm qhov kub siab, nws yog ib qho tsim nyog los nrhiav cov khoom siv los txheej cov khoom kub siab, uas tuaj yeem tiv thaiv flake graphite los ntawm oxidation ntawm qhov kub siab. Txhawm rau nrhiav hom graphite anti-oxidation tsho tiv no, peb yuav tsum xub muaj qee yam ntxwv xws li kev tiv thaiv kub siab, kev sib xyaw zoo, kev ua haujlwm tiv thaiv corrosion zoo, muaj peev xwm tiv thaiv oxidation muaj zog thiab kev nyuaj siab. Tus editor hauv qab no ntawm Furuite Graphite qhia txog txoj kev tiv thaiv flake graphite los ntawm kev oxidized ntawm qhov kub siab:
1. Cov ntaub ntawv uas muaj lub zog cua tsawg dua 0.1333MPa (1650 ℃) thiab cov khoom zoo tau txais yuav.
2. Xaiv cov khoom siv iav uas ua tau raws li qhov yuav tsum tau ua raws li cov khoom siv kaw nws tus kheej, thiab ua kom nws dhau los ua cov khoom siv kaw qhov tawg hauv qhov kub ua haujlwm.
3. Raws li kev hloov pauv ntawm lub zog dawb ntawm kev sib xyaw nrog oxygen nrog qhov kub thiab txias, ntawm qhov kub ntawm steelmaking (1650-1750 ℃), xaiv cov ntaub ntawv uas muaj kev sib raug zoo nrog oxygen ntau dua li carbon-oxygen, ntes oxygen ua ntej, thiab oxidize lawv tus kheej los tiv thaiv flake graphite. Qhov ntim ntawm theem tshiab tsim tom qab oxidation yog loj dua li ntawm theem thawj, uas yog pab tau los thaiv cov channel diffusion ntawm oxygen thiab tsim cov oxidation barrier.
4. Thaum ua haujlwm kub, nws tuaj yeem nqus tau ntau yam xws li AL2O3, SiO2, Fe2O3 hauv cov hlau molten, thiab ua rau nws tus kheej sinter, yog li ntawd ntau yam kev suav nrog los ntawm cov hlau molten maj mam nkag mus rau hauv txheej.
Furuite Graphite Xiaobian ceeb toom tias qhov kub oxidation ntawm flake graphite hauv Suav teb cov chaw tsim khoom tseem ceeb yog 560,815 ℃ thaum cov ntsiab lus carbon yog 88% 96% thiab qhov loj me ntawm cov khoom me me yog siab dua -400 mesh. Ntawm lawv, thaum qhov loj me ntawm graphite yog 0.0970.105mm, qhov kub oxidation ntawm graphite nrog ntau dua 90% cov ntsiab lus carbon yog 600,815 ℃, thiab ntawm graphite nrog tsawg dua 90% cov ntsiab lus carbon yog 6200 ℃. Qhov zoo dua ntawm crystalline flake graphite, qhov siab dua qhov kub oxidation ncov thiab qhov tsawg dua qhov hnyav oxidation poob ntawm qhov kub siab.
