Deskripsyon pwodwi
Segondè fòs refraktory siman se yon materyèl siman idwolik ki fèt ak boksit tise byen tè ak kalkè kòm eleman prensipal mineral li yo, kod CA.
Kontni an Al2O3 nan CA50 gwo fòs siman REFRACTORY se pa mwens pase 50%, zòn nan sifas espesifik se pa mwens pase 320 (m² / Kg), tan an anviwònman inisyal se jeneralman 50 a 120 minit, ak tan final la anviwònman se 90 a. 180 minit. Fòs la ta dwe pi gran pase 50MPa apre 3 jou tès la.
Segondè fòs refractory siman ka divize an aluminate siman refractory, ba kalsyòm aluminate siman refractory, kalsyòm mayezyòm aluminate siman ak Baiyun selon konpozisyon diferan. Stone refractory siman, elatriye.
CH Refractries fabrike siman refraktè segondè fòs ak pèfòmans trè ki estab e li te ekspòte nan anpil peyi. Lè nou ekspòte nou pake siman refractory ak plis pase 4 kouch sak pou pwoteje siman kont imidite lè anbake sou lanmè a.
