Acid Proof Bricks

Acid-proof brick, commonly referred to as Chemical Resistant Brick or Acid Resistant Brick, is a specific kind of brick which is manufactured to resist acids, corrosive chemicals, and other harsh substances. Janta Overseas is an expert in producing acid-resistant bricks using high-quality raw materials, such as clay, SiO2, and acid-resistant bonding agents or resins.

Among the numerous positive qualities of acid-proof brick are its high density, high acid resistance, minimal water absorption, and strong resistance to corrosion. Because of its high density and minimal water absorption, acid-resistant brick can also withstand alkali at room temperature. However, at high temperatures, it is not resistive to alkali. These are frequently utilized in power plants. storage containers, galvanizing facilities, the petrochemical sector, and other locations where a high level of chemical resistance is required.
