Acid Resistance Bricks
Summary
● Acid Resistance Bricks consist of quartz, feldspar and clay, etc. It is a kind of corrosion-resisting material made through oxidizing and decomposing under high temperature. It has characteristics of acid-proof, low water absorption, no easy to be oxidized and polluted under normal temperature. And except hydrofluoric acid,phosphoric acid more than 300℃, dense alkali, it has good corrosion-resisting effect on many organic acid, inorganic acid, and alkalescence solution, etc.
● Also named Acid Proof Bricks, Acid Proof Tiles, Anti Acid Tiles, Acid Resisting Bricks, Anti Acid Bricks
● The output of our Acid Proof Bricks is about 10000-12000MT per year. Our brand, “CHNGN” .
● Our Acid Proof Brick series have been applied in many big acid resistant construction in China. At the same time, our products have been exported to many countries, for example Thailand, Indonesia, South Korea, UAE, Vietnam, etc.
