Acid-resistant Brick
Description of acid-resistant bricks：
Acid-resistant bricks have excellent strength and wear resistance, and outstanding corrosion resistance to organic and inorganic acids except hydrofluoric acid. Acid-resistant bricks are used in acidic atmosphere flues, autoclaves, recovery tanks, large acid-resistant tank containers and storage tanks in the acidic process papermaking industry.
