Do you know the inorganic fire brick

As far as we are concerned that there are so many Refractory products like insulating Brick,Ceramic fiber board. We all familiar with fire brick, but do you know about the inorganic fire brick?

Water-resistant fire brick is a non-combustible, water-resistant inorganic fire blocking material.Developed for the domestic inorganic fire blocking materials poor water resistance defects, 

The main components of inorganic fire brick are inorganic refractory materials and modifiers. The blocking material has excellent fire resistance, water resistance, and oil, salt water, corrosion-resistant; products are prefabricated block form. Particularly suitable for electric power, petrochemical, metallurgy, construction and other industries cable tunnel, cable trench building fire wall.
