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 of Insulating brick

Metallurgical Industry: blast furnace, hot blast furnace, heating furnace, etc..

Petrochemical Industry: ethylene cracking furnace, hydrogen furnace, the main furnace, heating furnace, etc..

Ceramic industry: roller kiln, kiln, etc..

Glass industry: glass furnace regenerator, etc.

Carbon industry: carbon furnace, etc..

Aluminum electrolysis industry: aluminum reduction cell, etc.

Other industries: tunnel kiln, shuttle kiln, etc.

 

Advantages of heat insulation brick

Low thermal conductivity: many air holes will bring good thermal insulation effect, energy saving.

High crushing strength: high crushing strength, volume stability.

Low heat storage: small heat storage, absorb more heat, energy-saving effect is obvious.

Q:The project cost in hydropower No.3 shaft wall is solid brick or insulating brick?
Aerated concrete for external walls is to save money. One side is the outer wall.. Solid bricks are the first thing, safety comes first.
Q:What bricks are thermal insulation bricks?
Thermal insulation brick is a new type of building material synthesized with macromolecule material. Grey, hollowed out bricks are basically.
Q:Masonry method for boiler refractory brick
Masonry of furnace bottom:(1) the bottom shall be leveled before masonry; when the masonry is made, the walls around the bottom shall be first laid, and the height shall be approximately higher than the surface of the hearth. Then the bottom horizontal line (for example, multi layer masonry, together with the layer line) is marked on the straight wall, and then the bottom can be built.(2) when the bottom is made of multi layer bricks, the masonry shall be carried out by layer by layer, and the upper, lower and the same floor shall be staggered. The long side of the surface brick shall be vertical to the direction of the flow of slag or gas.(3) the high temperature area and the furnace bottom which need to be frequently repaired must leave the expansion gap at the bottom of the furnace and the straight wall, and the asbestos rope or asbestos board will be embedded in the gap.
Q:Does the building with the exterior wall thermal insulation brick require adding an angle steel bracket in the middle of the brick?
There is no mandatory requirement, but the thermal insulation system should use expansion bolts to do the pullout test, and the exterior wall tiles also need pullout tests.
Q:What is the maximum temperature range of high temperature resistant insulation materials?
Materials defined as physical and chemical properties that allow them to be used in a high temperature environment are called refractory materials. Refractory materials are widely used in metallurgy, chemical, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest amount of metallurgical industry, accounting for 50% ~ 60% of the total output.
Q:How to do indoor thermal insulation
Indoor thermal insulation, as well as "folk prescription""Some owners also used some of the insulation sleeves, for example, light reflection, heat is also, by means of a reflected heat, indoor temperature increase, the specific approach is adopted, Kouban metal surface, can also use the kitchen stove using metal film or metal film for baking food, installed in the radiator the walls and the walls, so that the heat preservation and reflection cooling effect, but also does not affect the appearance. Again, the 40% heat and window glass heat loss on indoor winter, especially some French families, the feeling of winter indoor temperature is relatively low, methods can be used to paste glass insulation film and coated glass insulation coating to retain heat.
Q:What's the difference between refractory bricks and insulating bricks?
In the preferred insulation performance, the thermal conductivity of insulating brick insulation brick in general 0.2-0.4 (average temperature 350 - 25 DEG C) w/m.k, and the thermal conductivity of refractory brick in 1 (the average temperature of 350 - 25 DEG C) above w/m.k, which can obtain the insulation performance of insulating brick than refractory brick insulation performance is much better. In the degree of refractoriness, the refractoriness of insulating bricks is generally below 1400 degrees, while the refractoriness of refractory bricks is above 1400 degrees. In density, insulation bricks are generally lightweight insulation materials, the density is generally in 0.8-1.0g/cm3, and the density of refractory bricks are basically above 2.0g/cm3.
Q:Energy saving bricks or bricks?
Insulating bricks are mostly hollow or light bricks.It can be said to be energy-saving bricks, including insulation bricks
Q:What is the price of thermal insulation brick for exterior wall?
Hello, the exterior wall insulation has many practices, useful insulation bricks, but also useful particles of polystyrene insulation mortar mixed (thickness is not the same, the price is not the same);
Q:What material is good for indoor thermal insulation?
Now the main building to do insulation, and generally use benzene board, we do indoor heat preservation is generally used, glass cotton is glass fiber, contact the skin after particularly uncomfortable
