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.

Q:What is the difference between cement foamed thermal insulation board and thermal insulating brick?
The main difference between cement foamed thermal insulation board and insulating brick is that the shape is different, one is plate, and the other is brick. Both are new walls to achieve the effect of energy conservation and insulation.
Q:The project cost in hydropower No.3 shaft wall is solid brick or insulating brick?
From the structure principle, hydropower shaft with solid brick, is to consider the safety performance of the structure.
Q:What is mullite insulation brick?
Main features of mullite insulating bricks:1., green environmental protection, non-toxic, non corrosive, safe to use.2. 、 good adaptability with cement.3., light insulation brick with foam mechanism bubble, can get foam uniform bubble diameter.4. excellent foaming performance, foaming multiples of more than thirty times.
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: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 thermal insulation performance of aerated bricks?
Aerated brick light weight, heat preservation, heat insulation, sound insulation, easy processing, using a variety of hybrid material production, rich production of raw materials, especially the use of fly ash, and comprehensive utilization of industrial waste, environmental pollution, saving farmland, have a good social and economic benefits, is an alternative to the traditional solid clay brick ideal wall materials. Gongyi Machinery Factory is specialized in producing aerated brick equipment manufacturers.
Q:Is the building built of cement hollow board safe?
The service life of hollow slab buildings is generally 50-70 years. However, the concept of civil design is relatively conservative, as long as the materials used in strict accordance with national standards, even if 70 years, and not necessarily bad.
Q:Are there any special requirements for the use of raw materials in thermal insulation brick production equipment? What about the raw materials?
. The control system needs to break, pouring the completion of data acquisition and process control of production site, steam curing process monitoring and control, production line of aerated brick Deyi heavy do better and integrity, production operation management etc..
Q:What are the bubble bricks?
The steam free aerated block has the advantages of wide raw material sources, high waste rate and low cost. With fly ash, slag, sand, sand, soil containing low amount of powder and tailings as the main raw materials (with one can), local materials, low cost, high profit.
Q:Difference between inorganic insulation material and organic thermal insulation material
Manufacturing distinction:1, organic insulation materials mainly from petroleum products, including foam polystyrene board (EPS), extruded polystyrene board (XPS), spray polyurethane (SPU) and polystyrene particles. From a nationwide perspective, the organic exterior wall insulation system occupies more than 75% of the current external thermal insulation Market in our country.2, inorganic heat preservation material including expanded perlite, hollow glass beads, rock wool, mineral wool, perlite, glass wool and lightweight block self insulation system, mainly based on inorganic materials such as stone, glass, industrial waste and so on. As the state attaches importance to and requirements of the fire protection safety standards for wall materials, the market share of inorganic thermal insulation materials will be greatly improved.
