Producdt Description of Chinese Factory Hot Sale Acid Proof Brick Lining
Acid proof brick or acid resistant brick is a specially made form of masonry brick that is chemically resistant and thermally durable. Acid proof brick is created from high silica shale and fired at higher temperatures than those used for conventional brick.
Features of Acid Resistant Refractory Bricks For Kilns
Application of Hot Sale Acid Proof Brick Lining
Acid-resistant refractory bricks are essential components in various industrial settings where corrosive acids are present. They serve as protective linings in equipment such as chemical reactors, metal smelting furnaces, and petrochemical processing vessels. These bricks are made from materials like silica, alumina, and zirconia, which can withstand the corrosive effects of acids. Their applications span across industries including chemical manufacturing, metal smelting, petrochemical refining, power generation, waste incineration, pharmaceuticals, glass manufacturing, and food processing. By providing a robust barrier against acid corrosion, these bricks ensure the longevity and reliability of critical industrial equipment.
