Choosing Suitable Acid Proof Bricks
- Different Compositions: Ronghua offers chemical resistant bricks made of clay, quartz, feldspar. Please choose the appropriate type of brick based on the usage scenario.
- Glazed Coating: Acidic refractory bricks with a glazed surface have a smooth finish, anti-adhesion and are easier to clean. Unglazed bricks have anti-slip and sun-resistant properties.
- Grooves: Acid resistant tiles can be made into single-face grooves and double-face grooves.

Advantages of Acid-Resistant Bricks
- Strong Acid Resistance: These refractory fire bricks have excellent resistance to most acids, for example, nitric acid, sulfuric acid, and hydrochloric acid.
- Corrosion Resistance: Ronghua produces acid-resistant bricks by firing high-density silicate at high temperatures. They effectively resist corrosion from acids, alkalis, and chemicals.
- Good Abrasion Resistance: With high surface density and hardness, they exhibit good abrasion resistance and a long service life.
- Low Water Absorption: They are not easily penetrated by acidic substances.
- Low Apparent Porosity: The raw materials and firing process result in low apparent porosity in acid proof bricks.
- High-Temperature Resistance: These bricks can be used at elevated temperatures.
- Good Thermal Shock Resistance: They remain stable under fluctuating high temperatures.
Applications of Acid-Resistant Bricks
Anti-acid refractory bricks serve as essential protection for equipment operating in acidic atmospheres and high-temperature slag erosion environments, such as in the petroleum, chemical, pharmaceutical, metallurgical, power, chemical fiber, papermaking, fertilizer, wastewater treatment, food, and dairy industries.
The uses of these products matched with monolithic refractory products are mainly for phosphoric acid storage tanks, acid trenches, acid wells, acid storage tanks, and impacted surfaces with high acid content, lining equipment, pipes, valves, electroplating tanks, and so on.
Note: When laying acid-resistant bricks, customers ensure that the joints between the bricks are completely sealed, with no air bubbles or voids. Otherwise, it may lead to brick spalling.
