Product Introduction
Acid proof brick is a corrosion-resistant and acid resistant material made of quartz, feldspar and clay through high-temperature firing.
Acid proof brick has excellent properties such as high acid resistance, high density, low water absorption, good corrosion resistance, low oxidation and pollution at room temperature.
In addition to hydrofluoric acid and hot phosphoric acid, acid resistant bricks can resist most acids, such as warm chloride salt water, hydrochloric acid, sulfuric acid and nitric acid. It can also resist bases of different densities at room temperature.
Acid proof brick main component is SiO2. When SiO2 is burned in high temperature, there are lots of polyaluminum andalusite which can resist acids strongly. Acid resistant brick also can resist alkali at room temperature because of high density, low water absorption. But it does not resist alkali at high temperature.
Specification
| Acid Proof Brick | Value |
| SiO2，% | 60-70 |
| Al2O3，% | 20-30 |
| FeO，% | 0.5-3 |
| Bulk Density, g/cm3 | 2.3-2.4 |
| Acid Resistance, % | ＞99.8 |
| Water Absorption, % | ≤0.5 |
| Bending Strength, Mpa | ＞58.8 |
Application of Acid Proof Brick
Acid proof brick is widely used in chemical industry such as workshop, outdoor acid resistant floors, anti corrosion lining of tower, tank, sink, etc.
