Acid-resistant brick is a special brick with excellent acid resistance, high temperature resistance and chemical corrosion resistance, which is widely used in chemical, metallurgical, electric power and other industries. It can work stably for a long time in strong acid and high temperature environment, has high mechanical strength, and excellent compression and impact resistance. At the same time, the surface of acid-resistant brick is smooth, which is easy to clean and maintain, and prolongs the service life of equipment and facilities. Its excellent performance makes it an ideal choice for harsh working conditions.
