Product Description:

General Information

CMAX insulating firebricks are classified under temperature between 1300℃ to 1700℃, manufactured from high purity alumina clay.

1. Lower content of iron, alkaline and impurities, good high temperature properties.
2. Homogeneous structure, light weight, energy saving because lower heat storage in the furnace during cooling cycles.
3. High strength, good thermal shock resistance under high temperature.
4. Precise sizes due to grinding and shaping after sintering, which meets the requirement of construction.
5. Max service temp: Up to 1730C (3160F)

 

Feature
Light weight and low thermal conductivity    
Low heat storage  
Low iron and impurities  
High thermal shock resistance

 

Application
CMAX insulating firebricks can be used as a hot face lining directly exposed to the heat or as a backup insulation layer in iron and steel mills, non-ferrous foundries, petrochemical, ceramic, glass.

Q:What is the price of concrete self insulation bricks
If you really want to buy thermal insulation brick, do not simply look at the price, but also to consider the quality of the product. (a piece of brick in the market basically in 6 yuan, if there is a floating price if it is because of the size of the insulation brick or distance, but floating slightly.)
Q:What is the bulk density of insulating bricks?
National classification standard: water absorption rate of ceramic tile is less than or equal to 0.5%;
Q:How much is a thermal brick
If you really want to buy thermal insulation brick, do not simply look at the price, but also to consider the quality of the product. (a piece of brick in the market basically in 6 yuan, if there is a floating price if it is because of the size of the insulation brick or distance, but floating slightly.)
Q:What are the types of building blocks?
Ordinary housing: building brick (clay brick), and non sintered brick (sand lime brick, fly ash brick, cement brick, etc.)
Q:Several kinds of energy-saving bricks
The insulation brick integrates the excellent heat preservation effect into the wall while building the wall. Low thermal conductivity, high strength, strong durability, simple construction, light weight, easy loading and unloading, economic, green, environmental protection, sound insulation, fire protection and so on.
Q:Material and making method of light insulating brick
The strength products are made of high quality tabular corundum and mullite as aggregate, silicon carbide as matrix, additional special additive and a small amount of rare earth oxide to be mixed, and then formed by high pressure molding and high temperature sintering.
Q:What is the exterior wall insulation material made of graphite?
Graphite is polystyrene board, polyurethane graphite plate, from the point of view of building the acceptance specification in the use process, the core index of insulation material is the heat transfer coefficient and safety, by now a large number of glazed hollow bead slurry from the actual situation it seems difficult to ensure the quality of construction materials should be on site workers slurry mixing, finished product the quality gap made out of very large.
Q:If there is a main component of cenosphere light insulating brick.
Light heat insulation brick with cenosphere composition, material properties will be more high, especially the main properties of thermal conductivity
Q:How shall the sintered porous self insulation bricks be laid at the bottom of the beam?
Compared with ordinary bricks, porous brick has the following masonry points: 1. All bricks must be watered before they are built, and no bricks are allowed to be applied to the wall.
Q:The insulation layer destroyed after use of cement paste and tiling
The most certain and the method can increase the area of the balcony is to eradicate the insulation layer exposed after cement wall tiles.
