Acid Proof and Refractory Brick

Acid Proof and Refractory Brick are used as the inner lining of reactors in drying and absorption towers. They are ideal for use in chemical plants, chemical fertilizer plants, and sulfuric acid plants. The acid proof and refractory brick are extensively used as the inner lining of anticorrosive pools and channels, and can be used for the construction of anti-acid ground.
