Lightweight acid resistant castable is composed of aluminate cement, high alumina fine material, ceramic particles, and several additives.

This product is lightweight, has high compressive strength, and is resistant to acid and acidic gas corrosion. The product has the characteristics of low insulation, thermal insulation, and water absorption rate, and is easy to construct. It is an ideal product for construction in high temperature areas with alkali corrosion resistance. The construction is simple, the bonding strength is strong, the initial setting time and construction operation time are long, the strength increases quickly, the impermeability is strong, no acidification treatment is required, and it is easy to ensure the compactness and fullness of the masonry joints. It can significantly improve the airtightness, integrity, and anti-corrosion ability of the chimney lining wall.

Lightweight acid resistant castables are ideal refractory materials for lining high-temperature chimneys, flues, and air ducts. They can also be used in acid resistant projects such as acid resistant tanks and troughs in industries such as petroleum, chemical, and non-ferrous metallurgy. Acid resistant bricks, acid resistant mastics, and plastering materials are refractory materials suitable for insulation of power plant boiler chimneys and heating network pipelines. They have the characteristics of acid corrosion resistance, temperature resistance, heat stability, and easy construction.
