Acid-resistant bricks are corrosion-resistant and acid-resistant materials made of quartz, feldspar and clay as the main raw materials and fired at high temperatures. Acid-resistant bricks can withstand most acids, including hydrofluoric acid and hot phosphoric acid, warm chlorine salt water, hydrochloric acid, sulfuric acid, nitric acid, etc., and can withstand alkalis of different densities at room temperature.

1.Chemical Corrosion Resistance 2.Low Water Absorption 3.Good Mechanical Strength
This type of acid-resistant brick has no glaze on the surface, and the entire brick body is completely porcelainized after high-temperature firing, with low water absorption.
The surface of this type of acid-resistant brick is glazed, and the brick body is also fired at high temperature to be completely porcelainized, with low water absorption.
The surface of this type of acid-resistant brick is glazed, but the brightness of the glaze is not high, it looks better than plain unglazed bricks, but it is more non-slip than glazed acid-resistant bricks, and the brick body is also fully porcelain
Acid-resistant bricks are extensively utilized in chemical plants, electroplating workshops, and sewage treatment plants. They are capable of resisting the erosion of various acids, ensuring the durability and stability of the facilities in corrosive environments.
