Description
Lightweight insulating castable is aluminate cement, alumina fines, ceramic, plus a number of additives dubbed
Lightweight insulating castable construction is simple, is at high temperature and alkali corrosion construction site a good product.
Workability is good, strong bond, the initial setting time and construction operational for a long time, fast growth strength, impermeability and strong, no acidification treatment to ensure full dense masonry mortar joint.
Can significantly improve the ability of anti-corrosion lining the walls of the chimney tightness, integrity and lining.
Lightweight insulating castable advantage
- Light weight
- Compressive strength is good
- Low thermal conductivity
- Acid resistance and acid gas corrosion
- Good thermal insulation
- Low water absorption
