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:What is the function of insulating bricks? Where can I use it?
Thermal insulation bricks are mainly used in toilets, kitchens, TV sets, bedrooms, walls and so on. And brightly colored, various specifications, can be cut at random, the section neatly.
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:Material and making method of light insulating brick
Material production of ordinary light insulating brick clay, high alumina high strength low iron bead brick, mullite, high aluminum light insulating refractory brick, diatomite insulating refractory brick.
Q:What are insulation bricks for? Do not use high-rise buildings on the ah?
Heat preservation and heat insulation, that depends on the design of the drawing
Q:How to reinforce a porous brick foundation?
Enlarged section method: it is used for the relatively shallow foundation with independent depth, strip foundation, raft foundation, box foundation and pile foundation applicabilityPoor.
Q:There are several construction techniques for exterior wall insulation
Exterior wall insulationSingle material thermal insulation exterior wall: aerated concrete and sintered insulating brickComposite insulation exterior wall: according to the different settings of thermal insulation materials, it can be divided into internal insulation, external insulation and sandwich insulation exterior wall. Thermal insulation decorative integrated board.Other: insulation blocks, etc.
Q:Clay insulation bricks insulation, brick and ordinary clay brick, fireclay, brick distinction, and its use? Thank you
Thermal insulation brick is a new type of energy-saving building insulation technology with inorganic composite material as the main material. It is an ideal technology to replace the traditional wall insulation.
Q:What are the bubble bricks?
(non autoclaved aerated block equipment), wide range of technical uses. Using this technique, the mold can be used for producing hollow block, insulating brick, light wallboard and insulation board. It can also be used as lightweight concrete and poured into the insulation fields such as roofing, wall, wall and floor heating.
Q:Difference between inorganic insulation material and organic thermal insulation material
1, organic insulation material with light weight, good processability, high compactness, good insulation effect, but the disadvantage is: aging resistance, deformation coefficient, poor stability, poor security, easy combustion, ecological environmental protection is poor, difficult construction, construction cost is higher, and the limited resources. It is difficult to recycle.2, inorganic insulation materials with energy-saving, waste, heat insulation, fire protection, antifreeze, anti-aging and excellent performance, as well as low prices and other characteristics, can achieve A-level fire protection, has a wide range of market demand.
Q:Are there any differences between insulating bricks and refractory bricks
The insulation performance of thermal conductivity of insulating 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.
