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....

Acid-resistant castables have better acid resistance and are used in metallurgy, electric power, and chemical kilns. Acid-resistant castable ( https://www.hy-refractory.com/products/unshaped_refractory/acid-resistant-castable.html ) for a chimney is a new type of anticorrosive castable. It has good workability, convenient construction, and a moderate initial setting and final setting time. After high-temperature baking, the strength continues to increase, and the impermeability and acid resistance is not reduced. But acid-resistant castables have poor resistance to hydrofluoric acid and high fatty acids. Acid-resistant Castable Acid-resistant castables are castables that can resist acid corrosion at a temperature of 800-1200°C. Acid-resistant castable is a castable mixed with acid-resistant aggregate, powder, water glass, or phosphoric acid as a binder. The acid-resistant castable also has strong anti-corrosion performance, which can meet the requirements of acid corrosion and the fati...
