Acid Proof Brick, as a kind of corrosion-resistant refractory material, is manufactured with quartz, feldspar and clay as the main raw materials through oxygenolysis in the high temperature. Acid Proof Bricks have high acid-alkali resistance property, low water absorption and are not easy polluted by medium, which can be used in the anti-corrosion engineering such as petroleum, chemical engineering, metallurgy, electric power, chemical fiber, papermaking, pharmacy, chemical fertilizer, food, dairy industry and so on.
Acid Proof Brick is refractory brick with strong acid resistance and can be widely used in the industries. Acid Proof Brick is the ideal choose for your project with their features of proof pressure, corrosion resistance, easy to clean and acid-base resistance. Acid proof brick has dense structure, which can resist any pH indicator alkaline medium in the normal temperature, but not resist melting alkali in high temperature.
