Acid Proof Bricks

Acid Proof Bricks are fire bricks with strong acid resistance and can be widely used in industries. Acid Proof Brick is the ideal choose for your project with their features of proof pressure, corrosion resistance, easy to clean and acid-base resistance. This kind of brick has dense structure, which can resist any PH indicator alkaline medium in the normal temperature, but not resist melting alkali in high temperature. RS Fire Bricks Factory also provide light weight acid bricks for the chimney, which can withstand high temp 1000℃, sio2 content is 65%.

Acid Proof Bricks Chemical Composition

As a kind of corrosion-resistant refractory material, Acid Proof Brick is manufactured with quartz, feldspar and clay as the main raw materials through oxygenolysis in the high temperature. Due to the Acid Proof Bricks chemical composition, the refractory bricks have high acid-alkali resistance property, low water absorption and are not easy polluted by medium, which can be used in the anti-corrosion engineering such as petroleum, chemical engineering, metallurgy, electric power, chemical fiber, papermaking, pharmacy, chemical fertilizer, food, dairy industry and so on.

Acid Proof Brick Properties

  • Strong acid resistance
  • Wear resistance
  • Low water absorption
  • Low apparent porosity
  • High temperature resistance
  • Good thermal shock resistance
  • High mechanical strength

Acid Proof Brick Application

As the strong acid resistance property of acid proof bricks, they can be used in the high temperature equipments with acid atmosphere and slag erosion, such as in the industries of petroleum, chemical engineering, metallurgy, electric power, chemical fiber, papermaking, pharmacy, chemical fertilizer, food, dairy industry and so on.

Acid Proof Brick Lining Procedure

When do the construction of acid proof brick lining, it is necessary to pay carefully attention to bricks-laying. If the laying is not dense or there is bubble or interspace, it is dangerous to result the brick spalling. When laying the acid brick lining, clean up the surface and make sure the dense between bricks. All carefully construction that can keep the quality of acid proof brick lining, which will prolong the life of furnace or kiln.
