Acid-resistant brick
- Commodity name: Acid-resistant brick
- Product Description
-
The main component of acid-resistant tiles is silica, which forms a large amount of mullite under high-temperature roasting, which is a substance with high acid resistance. Because of the acid-resistant brick structure is close, the water absorption rate is small, so at room temperature can also be resistant to any concentration of alkaline medium, but not high temperature molten alkali. Acid-resistant bricks contain more than 70% silica and are sintered. They are mostly used in the chemical industry to build acid ditches, acid wells, acid storage reservoirs and impacted ground with large acid carriers.
