Cov Khoom Qhia Txog Khoom

Cov Cim Npe Khoom

Silicate carbon cib yog cov khoom siv tsis muaj zog, uas tiv taus kev yaig ntawm cov kua qaub thiab alkali slags, cov kuab tshuaj, thiab lwm yam tshuaj lom neeg xeb. Silicon carbide muaj cov yam ntxwv ntawm lub zog siab, tiv taus kev tiv thaiv oxidation zoo, thiab tsis hloov pauv ntawm qhov kub siab. Hauv txhua yam khoom siv raw ntawm cov cib tsis-oxide refractory, slilica carbon cib yog qhov pheej yig tshaj plaws thiab siv dav tshaj plaws hauv qee qhov chaw. uas tuaj yeem siv rau hauv ntau yam lag luam, xws li kev lag luam pob zeb, kev lag luam iav, kev lag luam hlau, kev lag luam luam ntawv, thiab kev lag luam lub teeb. Dhau li ntawm qhov ntawd, Silica carbon cib muag muaj kev ua tau zoo heev ntawm kev tiv taus kev yaig ib puag ncig phem heev, xws li kev ua kom sov siab, kev tiv taus abrasive zoo, kev tiv taus thermal shock zoo, muaj zog tiv taus kev yaig ntawm acid thiab alkali slag thiab coefficient nthuav dav cua sov qis thiab lwm yam.

Cov khoom xyaw ntawm Silica Carbide Cib

Cov khoom siv raw ntawm silicate carbide block yog silicon carbide, kwv yees li 72% -99%. Silicon carbide tseem hu ua moissanite, corundum xuab zeb lossis refractory xuab zeb. uas yog ua los ntawm quartz xuab zeb, roj av coke lossis thee tar, thiab cov ntoo me me, uas raug tsim los ntawm kev kub siab smelting hauv lub cub tawg hluav taws xob.

Cov Txheej Txheem Tsim Khoom Siv Silica Carbide

Cov cib silicon carbide yog tsim los ntawm silicon carbide, cov khoom siv raw uas tau tsim los ntawm lub cub hluav taws xob tiv taus ntawm qhov kub tshaj 2500 ° C, los ntawm kev sib xyaw ntawm silica nrog carbon. Cov cib carbon silicate muaj cov thermal conductivity kaum npaug ntawm cov fireclay refractories, zoo corrosion thiab thermal shock tsis kam, thiab tuaj yeem tsim ua cov duab nyuaj. Silica cabon cib tuaj yeem tiv taus slag tawm tsam thiab nplaim taws erosion.

Kev faib tawm ntawm Silica Carbide Cib

Cov cib refractory silicon carbide tuaj yeem muab faib ua cov cib av nplaum sib txuas nrog silicon carbide, Si3N4 sib txuas nrog silicon carbide cib, Sialon sib txuas nrog silicon carbide cib, β-SiC sib txuas nrog silicon carbide cib, Si2ON2 sib txuas nrog silicon carbide cib thiab recrystal silicon carbide cib.
