Acid Resistant Refractory Bricks Acid Proof Brick For Industrial Kiln
Acid resistant bricks, also known as acid bricks or acid-resistant bricks, are specialized types of bricks designed to withstand corrosive environments, particularly those involving acids and other harsh chemicals. They are commonly used in industries where there is a need for protection against the damaging effects of acids, such as chemical processing plants, laboratories, refineries, and various manufacturing facilities.
Types of Acid Resistant Bricks:
Silica Bricks: Made primarily from silica, they offer excellent resistance to acids, but they may not be suitable for applications involving high temperatures.
Fire Clay Bricks: These are made from a combination of fire clay and kaolin. They provide good resistance to both high temperatures and acids.
Specialized Compositions: Some acid resistant bricks may have additional components or coatings to enhance their performance in specific environments.
