Acid-resistant tiles and bricks are refractory materials specially used to resist corrosion from acidic media. They are usually used in various acidic environments in chemical, metallurgical, electric power, petroleum, pharmaceutical, food, papermaking, and other industries. Acid-resistant bricks have excellent acid resistance and mechanical strength and can be used for a long time in strongly acidic media to ensure the safe operation of equipment and facilities. Acid-resistant tiles a acid-resistant bricks have different sizes.

Characteristics of acid-resistant bricks
Excellent acid resistance
Acid-resistant bricks are made of high-quality clay, quartz, and a certain proportion of acid-resistant materials, and are fired at high temperatures. Its main feature is that it can resist the corrosion of various strong acids such as sulfuric acid, hydrochloric acid, and nitric acid, and can maintain stable chemical properties even in a high-concentration acid environment. Its acid resistance can reach more than 99%.
High mechanical strength
In addition to excellent acid resistance, acid-resistant bricks also have high mechanical strength and wear resistance and can withstand greater pressure and wear. No reira, it is often used on occasions that need to carry heavy objects and frequently contact acidic media, such as pickling tanks, acid pools, acid towers, and acid storage tanks.
Good temperature resistance
Acid-resistant tiles and bricks can withstand a certain high temperature, and their temperature resistance range is generally below 800℃. In a high-temperature acidic medium environment, acid-resistant bricks can maintain the stability of their physical and chemical properties and are not prone to decomposition and damage.
Thermal shock resistance and stability
Due to the dense structure and uniform texture of acid-resistant bricks, they have good thermal shock resistance and volume stability. In an environment with sudden temperature changes, it can effectively prevent cracking and disintegration and extend its service life.
In which industries are acid-resistant tiles used?
Chemical industry
In the chemical industry, acid-resistant bricks are mainly used for lining equipment such as pickling tanks, acid pools, acid towers, and acid storage tanks to prevent acidic media from corroding and damaging the equipment and extend the service life of the equipment.
Metallurgical industry
In the metallurgical industry, acid-resistant bricks are often used in the acidic environment of steel mills and aluminum smelters to pave acid storage tanks, pickling workshop floors and walls, etc., to ensure that the acidic medium does not leak and does not corrode the equipment.
Power industry
In the power industry, acid-resistant tiles are used in desulfurization towers, flue gas desulfurization equipment, and other devices in power plants to resist corrosion from acidic gases and liquids and protect the safe operation of equipment and facilities.
In the food and pharmaceutical industries
Acid-resistant tiles and bricks are also used to line some special equipment in the food and pharmaceutical industries to protect the equipment from corrosion by acidic media and ensure the safety and hygiene of the production environment.
Papermaking industry
In the papermaking industry, acid-resistant bricks are used in acid waste liquid treatment equipment and storage tanks to ensure that the acid waste liquid does not corrode the equipment and reduce the pollution of the environment by acidic substances.
