Product introduction of Acid resistant refractory castable
Acid resistant refractory castable is a castable refractory that can resist the corrosion of acidic medium at 800-1200 ℃. It is composed of water glass as binder, acid or semi acid refractory as aggregate and powder, and a small amount of coagulant.
Application of Acid resistant refractory castable
Acid resistant refractory castables are widely used in metallurgy, chemical industry, petroleum, light industry and other thermal equipment.
Advantages of Acid resistant refractory castable
- High temperature resistance.
- High tensile strength.
- Acid corrosion resistance.
- Great uniformity.
- High humidity resistance.
- High content of water and anchoring agent.
- High compression ratio.
