Hom thiab siv castable?
Castable yog cov khoom siv refractory, feem ntau yog siv los muab kev tiv thaiv thiab kev txhawb nqa hauv qhov kub thiab txias. Cov hauv qab no yog hom thiab kev siv ntawm castables:
1. Corundum castable: Corundum ua cov khoom siv tseem ceeb, ntxiv qhov tsim nyog ntawm cov ntaub ntawv tsim. Feem ntau yog siv rau hauv lub qhov cub kub kub, qhov kub thiab txias pipeline, blast furnace hauv ob sab phlu thiab lwm yam khoom siv kub.
2. Silicon carbide castable: silicon carbide ua cov khoom siv tseem ceeb, ntxiv qhov tsim nyog ntawm cov ntaub ntawv ua. Feem ntau yog siv hauv kev tsim cov khoom siv silicon carbide, hnav qhov chaw, kub kub thiab lwm yam khoom siv kub.
3. Hnav-resistant castable: ua nrog hnav-resistant aggregate raws li cov khoom siv tseem ceeb thiab ntxiv cov khoom tsim nyog ntawm binder. Feem ntau siv rau hauv cov khoom siv kub-resistant, xws li cov cement kilns, thee-fired boilers thiab hais txog.
4. High aluminium castable: ua nrog siab aluminium ua cov khoom siv tseem ceeb thiab ntxiv qhov tsim nyog ntawm binder. Feem ntau yog siv rau hauv qhov cub kub, kub kub thiab lwm yam khoom siv kub.
5. Thaum tshav kub kub rwb thaiv tsev castable: nrog refractory fiber ua lub ntsiab raw khoom, ntxiv ib tug tsim nyog tus nqi ntawm binder ua. Nws yog tsuas yog siv rau cov khoom siv hluav taws xob kub kub, xws li sab saum toj thiab lub cub tawg phab ntsa ntawm cov kub kub kiln.
6. Acid-resistant castable: siliceous khoom raws li lub ntsiab raw khoom, ntxiv ib tug tsim nyog tus nqi ntawm binder ua. Nws yog tsuas yog siv rau hauv kev tsim cov khoom siv acid-resistant, xws li cov kav dej kub thiab cov reactors hauv sulfuric acid nroj tsuag.
7. Alkali resistant castable: tsawg cement castable los yog phosphate castable raws li lub ntsiab raw khoom, ntxiv ib tug tsim nyog tus nqi ntawm binder ua. Nws yog tsuas yog siv rau hauv kev tsim cov khoom siv alkali-resistant, xws li cov kav dej kub thiab cov reactors hauv cov nroj tsuag tshuaj.
Nyob rau hauv luv luv, castables muaj zoo heev kub khoom, corrosion kuj thiab mechanical zog, thiab yog dav siv nyob rau hauv cov khoom tsim thiab txij nkawm nyob rau hauv ntau yam kub qhov chaw.
