Acid resistant refractory castable is able to resist to the corrosion of 800-1200℃ acid medium castable refractory. It is made up of water glass as binding agent, acid or semi-acid refractory as aggregate and powder, added a small amount of coagulant.
Applications:
In metallurgy, chemical industry, petroleum, light industry and other thermal equipment is widely used.
Properties:
1.High temperature resistance.
2.High tensile strength.
3.Acid erosion resistance.
4.Great uniformity.
5.Resistant to high humidity.
6.High content of water and anchoring agent.
7.High compression ratio.
