The Main Components and Applications of Acid-Resistant Castables
Acid-resistant castable refers to a refractory castable that can resist corrosion by acidic media at a temperature of 800 to 1200°C. It is mainly prepared by using water glass as a binder, acidic or semi-acidic refractory materials as aggregate and powder, and a small amount of coagulant. The disadvantage of this castable is that it cannot be used where there is an alkaline corrosive medium. Next, let's learn more about the main components of acid-resistant castables and their applications. Acid-Resistant Castable The main components of acid-resistant castables The main components of acid-resistant castables are water glass , hardening accelerators, acid-resistant refractory aggregates, and powders. Acid-resistant refractory aggregates and powders mainly include particles such as silica, cast stone, wax stone, diabase, and fine powders of acid-resistant materials such as waste silica bricks, silica, waste porcelain, and cast stone. Water glass is generally used as a bonding agent....
