Product introduction of acid resistant castable
Acid resistant castable is one of the amorphous materials. Like other amorphous refractories, acid resistant castable can be directly used in the project without firing. In addition, acid resistant castables refer to castable refractories that can resist the corrosion of acidic media (nitric acid, hydrochloric acid, sulfuric acid, acetic acid, etc.) at 800~1200 ℃.
Features of acid resistant castable
- Energy conservation
- High production efficiency
- Arbitrary modeling
- Suitable for various high-temperature projects
Application of acid resistant castable
The acid resistant castable has good corrosion resistance to all inorganic acids and organic acids except hydrofluoric acid and hot phosphoric acid. It is mainly used as anti-corrosion lining, and the higher service temperature is about 1200 ℃. Acid resistant castable can be used flexibly. It can not only be used as unshaped refractory, but also can be made into various irregular prefabricated parts for use. Reasonable use can give play to the relatively large performance of acid resistant castable.
