Cov Ntaub Ntawv Uas Muaj Silica Siab
Kev piav qhia txog khoom
Cov xov paj silica siab yog ib hom fiber tshwj xeeb mos uas muaj kev tiv thaiv ablation, tiv taus kub siab, tiv taus corrosion thiab lwm yam ntxwv. Nws tuaj yeem siv tau ntev ntawm 1000 ℃, thiab qhov kub thiab txias tam sim ntawd tuaj yeem ncav cuag 1450 ℃.
Nws yog siv rau hauv ntau yam kev txhawb nqa, kev tiv thaiv corrosion, rwb thaiv tsev kub thiab lwm yam ntaub (cov khoom siv tseem ceeb rau kev tsim cov koob txhaj tshuaj) lossis cov ntaub ntawv sib xyaw ua ke.
Kev Ua Tau Zoo, Cov Yam Ntxwv & Cov Ntawv Thov
Cov ntaub silica siab yog ib hom khoom siv refractory zoo li daim ntaub uas muaj cov xov silica siab. Piv nrog cov ntaub silica siab ib txwm muaj, nws muaj qhov zoo ntawm qhov tuab siab, qhov hnyav sib dua, kev rwb thaiv tsev zoo heev thiab lwm yam. Qhov tuab ntawm cov ntaub silica siab nthuav dav tuaj yeem ncav cuag 4 hli.
Nws yog siv rau kev rwb thaiv tshav kub sab nraud thiab kev khaws cia cua sov ntawm ntau yam khoom siv kho tshuab thiab cov kav dej, thiab tuaj yeem ua cov ntaub vuam, daim ntaub thaiv hluav taws, khaub ncaws tiv thaiv hluav taws, hnab looj tes tiv thaiv hluav taws, khau tiv thaiv hluav taws, npog tiv thaiv cua sov, pam tiv thaiv cua sov, thiab lwm yam.
