Alkali Resistant Brick
Product Description And Parameters
Bulk density stability
Good anti-erosion character
Superior penetration resistance
Good slag resistant
Anti-alkali brick is made of silica, flint clay, combing with other additives reacting with alkaline oxide and efficiently stopping the alkaline slags into the bricks, to achieve the alkali resistance.
1. Bulk density stability
2. good anti-erosion character
3. superior penetration resistance.
4. good slag resistant
Application:Alkali-resisting bricks are widely used in the cement kilns, such as the areas of preheater, precalciner, and tertiary air duct elbow, ect. The demand amount can be max 30~40% during constructing these areas of kilns.
