Product Overview

Anti-infiltration castable is based on traditional ratio, adjusts the particle gradation, adds different admixtures, reduces the amount of cement, improves performance. It has high strong anti-infiltration, which can prevent the alumina liquid from penetration, eroding, can prolong the service life of the electrolytic cell, it can replace the refractory brick as anti-infiltration layer.

Application

Anti-infiltration castable mainly used to prevent aluminum liquid from penetration, can extend the service life of electrolytic cell.
