Acid Resistant Castable
Description
Acid resistant castables refer to castable refractory materials that can resist the corrosion of acidic media (nitric acid, hydrochloric acid, sulfuric acid, acetic acid, etc.) in a high temperature environment of 800-1200 °C.
Acid Resistant Castable Features
Acid resistant castables have the characteristics of small bulk density, fast solidification, high service temperature, compressive strength increases with the increase of temperature and acidity, small thermal conductivity, and small linear expansion coefficient.
