Acid-resisting Brick For Chimney

Jul 07, 2025

Acid-resisting Brick For Chimney is made of pottery clay and clay as the main raw materials, through mixing, molding, firing and other processes to produce acid resistant products. The product has high acid resistance and is not easy to be oxidized under normal temperature. Besides hydrofluoric acid and thermal phosphoric acid, it has excellent anti-corrosion effect on many acid substances. It is Widely used in electric power, metallurgy and other chimneys and flues.

1.Features of Acid-resisting Brick For Chimney:

1) High acid resistance, ≥ 97%, good anti-corrosion effect on most acids products

2) Small volume change, good corrosion resistance

3)Color is Purple red

2. Application: chimney, flue lining. In addition, it is used in anticorrosion equipment of petroleum, chemical industry, chemical fertilizer and other industries.

The main component of acid resistant brick is SiO2, which forms a lot of polyaluminal Andalusite in the process of high temperature sintering. It is a kind of material with high acid resistance. The acid resistant brick has compact structure (density ≥ 2.4g/cm3), low water absorption, and can withstand any concentration of acid medium at room temperature. The products are divided into heavy brick and light brick, both of which have good acid resistance atmosphere, air erosion and erosion performance. They are widely used in flue, chimney, coking furnace and chemical furnace.

3. The product is widely used in large chimneys, flues and coking furnaces in China and exported to Southeast Asia and other countries

4. Our company is free to provide users with technology, use and other services.
