Acid resistance refractory brick description
Acid resistance refractory brick is quartz, feldspar, clay as the main raw materials, by high temperature kiln fired into the corrosion resistant material. Environmental conditions for construction of acid resistance refractory brick: the temperature should be 15-30 ℃, and the relative humidity should not be greater than 80%.
Acid resistance refractory brick features
- High acid resistance
- Low water absorption
- It has impermeability, frost resistance, salt resistance, alkali resistance and weak acid corrosion resistance
