Acid resistant bricks are ideal industrial material especifically for highly corrosive and abrasive applications. This acid proof lining has excellent acid resistance and low water absorption, they can be directly used in acid-bearing and impact-exposed critical areas. Using acid resistant brick lining effectively withstands the long-term effects of strong acid environments.And it also prevents pulverization, cracking and flaking, thus fundamentally extending equipment lifespan.

Size Selection of Kerui Acid Resistant Bricks
We should choose the size of acid proof bricks according to the place of use, working conditions and installation method. If the workplace is often splashed by chemicals, you need to choose thicker acidic bricks to increase their corrosion resistance. In addition, When we lay the bricks, we need to choose larger acid-resistant bricks to ensure the flatness and aesthetics of the floor. However, when we inlay, we may need to choose smaller acid resistant bricks.

Features of KERUI Acid Resistant Lining Brick
Strong Load Bearing Capacity
The acid resistant bricks are dense and durable. It is ideal for use in kiln bases, piers and other areas that require heavy loads. The compressive strength ensures stable support for the entire furnace structure.
Outstanding Acid and Chemical Resistance
In kilns where acidic gases or molten materials may cause corrosion, Kerui acid resistant lining effectively prevents damage and extend service life. You can watch more videos at Youtube.
Stable Performance at High Temperature
This acid proof brick lining procedure maintains structural integrity under thermal cycling. It can ensure long-term reliability even in demanding firing conditions.
Versatile Lining Material
Acid brick linings are not only used as kiln linings but also as protective walls, floors, and flue linings where chemical attack is common.
Application of Acid Proof Bricks
KERUI acidic bricks have wide application in industrial kilns and equipment will face acidic media corrosion. The main function is to protect the foundation of the structure and the equipment itself from chemical corrosion, thereby extending the life of the facility and ensuring production safety.
Chemical Industry
Applications: Pickling tanks, electrolytic cells, reactors, chemical plant floors, trenches, etc.
Reason: In pickling workshops or chemical plants, floor pits will directly contact splashes or leaks of acidic liquids. Laying acid-resistant bricks to protect the tank or floor effectively creates a safe construction environment.
Petroleum Industry
Applications: Linings of acidic storage tanks, reactors, heat exchangers, and absorption towers.
Reason: For equipment with acidic gases and liquids, you can use acid proof bricks as a protective lining. This is crucial for effectively preventing acid or oil leaks and protecting the shell from damage.
Metallurgical Industry
Applications: Acid regeneration plants, flue gas purification systems (desulfurization towers).
Reason: In steel, aluminum, and copper smelters, flue gases contain acidic gases such as sulfur dioxide. Desulfurization tower linings must be made of acid-resistant bricks to resist sulfuric acid corrosion.
Power Industry
Application: Flue Gas Desulfurization (FGD) Systems.
Reason: This is one of the most classic and important applications for acid-resistant bricks. After desulfurization, the flue gas generated by coal-fired power plants is subjected to extremely corrosive conditions such as low temperature, high humidity, and dilute sulfuric acid. Acid-resistant bricks, combined with water glass mortar, are required to ensure the long-term safe operation of the desulfurization tower.
Wastewater Treatment
Application: Sewage tanks, neutralization tanks, aeration tanks.
Reason: Industrial wastewater often contains various organic and inorganic acids. Concrete tanks used to treat these acidic wastewaters must be lined with acid-resistant bricks for corrosion protection.
Other Industries
Application: Pharmaceutical, fertilizer, paper, and electroplating industries, among others.
Reason: Acid-resistant bricks are required for protection in any production, storage and transportation process involving acidic corrosive media.
