High Strength Type Alkali-Resistant Fire Refractory Brick for Chemcial Factory
The description:
High strength alkali resistant brick is made on the basis of ordinary type by adding additives to improve the compressive strength. The alkali-resistant brick uses silica, coke gem and appropriate additives to improve the microstructure of the product. In the process of use, a high-viscosity glass phase is generated by the reaction of alkaline oxide, which covers the surface of the brick and blocks the surface porosity, prevents the infiltration of alkaline slag, and plays the purpose of alkali resistance and corrosion resistance.
