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.

 

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

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..

 

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: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:What are the sizes of lightweight thermal insulation bricks?
The production of material ordinary lightweight insulating refractory brick with fireclay and high alumina high strength bead brick
Q:Is the quality of brick made of small-sized self insulation block equipment the same as that of large block brick equipment?
In fact, brick and tile production is only a different production, the quality of brick produced is the same, from the silver horse experience
Q:What kind of material is clay insulation refractory brick made of?
Alumina silicate refractories with a content of 30% ~ 46% are called clayey refractories. Clay products are mainly made of mullite, glass phase, square quartz and quartz.
Q:What is the difference between the production line of foamed cement insulation bricks and the self thermal insulation block production line?
Yes, this year's business is not very good to do, customers pay more attention to the quality of products, seven industrial equipment, very satisfied with the service OK
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:Energy saving bricks or bricks?
Energy saving brick may be cement slag, or cement, water residue, cement, coal ash, etc. overview
Q:Are there any differences between insulating bricks and refractory bricks
The degree of refractoriness of insulating bricks is generally below 1400 tons, while the refractoriness of refractory bricks is above 1400 degrees. 3. 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:Is it necessary to abolish the technical regulations for the construction of self thermal insulation masonry building with sludge sintering insulation bricks?
Silt sintering brick insulation brick is made from river mud, city sludge, mud as the main raw materials, added according to a certain proportion of siliceous inorganic binder after aging, extrusion blank, blank by cutting, drying, sintering and extrusion molding machine. The utility model has the advantages of energy saving, resource saving, favorable for developing circular economy and comprehensive utilization of resources, high micropore rate, good product heat insulation performance and heat insulation performance, etc..
Q:Is sintering insulation brick good or concrete porous brick good?
Thermal insulation brick is functional material, it is better than porous brick in thermal insulation. At the same time, the internal heat preservation material, so the overall cost is more, the hole brick should be higher.
