Acid-resistant castable is a castable that can resist the corrosion of acidic media, such as nitric acid, hydrochloric acid, sulfuric acid, and acetic acid, at a temperature of 800-1200 °C, and has good acid resistance. Acid Resistance Castable is used in metallurgy, chemical industry, and other parts.
Acid Resistance Castable Introduction
Acid resistant refractory castable is a refractory castable that can resist acid and acid gas erode, which is made of acid-resistant refractory material as aggregate and powder, and water glass as binder. Acid resistance refractory castable have the good ability to resist the erosion of all inorganic acids and organic acids other than hydrofluoric acid and thermal phosphoric acid. Acid-resistance castable is mainly used as anti-corrosion lining, and the maximum use temperature is about 1200℃.
Acid Resistance Castable Composition
Acid resistant castable is a refractory material that can resist corrosion at 800~1200 ℃ acidic medium (nitric acid, hydrochloric acid, sulfuric acid, acetic acid, etc.). It is made of water glass as binder, acid or semi acid refractory as aggregate and powder, and a small amount of coagulant.
Acid Resistance Castable Advantages
- Good acid resistance performance
- Better using effect than acid resistance brick
- Even distribution of temperature of furnaces
- High refractoriness
- Good abscission resistance
- Good compression strength
- Long service life

Acid Resistance Castable Technical Performance
- Acid resistant castables are stable in various concentrations of organic acids and inorganic acids, especially it don’t produce crystalloid saltin in dilute acid, industrial water and neutral aqueous solution, have high anti permeability.
- Good heat resistance, lining in titanium pigment rotary kiln, the use temperature is as high as 950 ℃- 1000℃.
- The acid resistant castable is harmless to the operator and the construction personnel by using the non-toxic curing agent. It can be used in various equipment anticorrosion works after being identified by the health department.
- Acid resistant castables are cheaper than organic acid resistant materials. It has the same properties as corrosion resistance of organic acid, and has the unique properties of corrosion resistance to strong oxidizing medium.
- Room temperature curing, simple construction, easy to use, easy to transport, moisture-proof storage
Acid Resistance Castable Application
Acid-resistance refractory castable is widely for linings of various furnaces, and anti-corrosion lining and the maximum using temperature is about 1200℃.
