Silicon Carbide Cib
Pob zeb silicon carbideyog cov khoom siv refractory ua los ntawm silicon carbide (SiC) ua cov khoom siv tseem ceeb. Nws muaj cov yam ntxwv ntawm kev tawv siab, kev hnav tsis kam siab, kev ua kom sov siab thiab kev tiv thaiv corrosion zoo. Nws cov khoom tseem ceeb yog silicon carbide, thiab cov ntsiab lus feem ntau yog ntawm 72% thiab 99%. Cov hom feem ntau suav nrog cov cib silicon carbide uas sib txuas nrog av nplaum, cov cib silicon nitride uas sib txuas nrog silicon carbide, cov cib Sialon uas sib txuas nrog silicon carbide, thiab lwm yam.
Kev faib tawm:
Cov cib silicon carbide tuaj yeem muab faib ua pawg hauv qab no raws li ntau txoj kev sib txuas sib txawv:
Cov cib silicon carbide uas sib txuas nrog av nplaum:av nplaum yog siv ua ib qho binder, tsim rau cov sijhawm uas xav tau kev thermal conductivity thiab thermal shock resistance.
Cov cib silicon carbide sib txuas nrog silicon nitride:raug rho tawm haujlwm los ntawm kev ua haujlwm nitriding, nrog kev ruaj khov zoo heev thiab kev hnav tsis kam.
Cov cib silicon carbide uas sib txuas nrog Sialon:ua ke nrog Si3N4 thiab Al2O3 hmoov, tsim nyog rau qhov kub thiab txias thiab tshuaj lom neeg xeb.
Nta:
Kev nyuaj siab:Qhov Mohs hardness ntawm silicon carbide cib yog 9, thiab nws muaj kev tiv thaiv kev hnav siab heev.
Kev ua tau zoo ntawm cov cua sov:Nws muaj cov thermal conductivity siab thiab tsim nyog rau cov sijhawm uas xav tau kev kub sai sai.
Kev tiv thaiv xeb:Nws muaj kev ruaj khov zoo rau acidic slag thiab yog qhov tsim nyog rau ntau yam kub thiab tshuaj lom neeg corrosion ib puag ncig.
Kev tiv thaiv thermal poob siab:Nws muaj kev tiv thaiv thermal zoo thiab tuaj yeem ruaj khov nyob rau hauv kev hloov pauv kub sai.
