Acid Resistant Castable
Acid Resistant Castable
Acid resistant castable has good performance to withstand acid erosion. It’s one of an important refractory castable in construction of high temperature kilns. The acid-resistant castable has good corrosion resistance to all inorganic and organic acids except hydrofluoric acid and hot phosphoric acid. With high strength at room temperature, the production process and construction are simple.At the same time, the material utilization rate is high. In addition, it can also be made into preforms and installed at the kiln spinning site, such as chimney lining pouring.
