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: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:How shall the sintered porous self insulation bricks be laid at the bottom of the beam?
And the concrete beam should be broken brick masonry. Top packing.
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.
Q:The difference between ordinary and diatomite brick refractory brick?
Insulation products made from diatomaceous brick and porous diatomite. The main raw material is natural porous diatomite, and then a small amount of clay and fuel are added. The volume density of diatomite brick was 0.7g/cm3, compressive strength at room temperature is 1 ~ 2MPa, the coefficient of thermal conductivity at 400 C for 0.13 ~ 0.20W/ (M - K), the apparent porosity is greater than 70%, the coefficient of thermal expansion (1280 degrees) 0.9 x 10 - 6 DEG -1, refractoriness is greater than 1250 DEG C. Mainly used in industrial kilns and other thermal equipment, thermal pipes insulation materials, generally withstand the hot surface temperature of about 1000 degrees celsius. Mainly used in industrial kilns and other thermal equipment, thermal pipes insulation materials, generally withstand the hot surface temperature of about 1000 degrees celsius.
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 improvements and improvements during the trial production of insulating bricks?
Insulation brick seven characteristics: insulation, heat insulation: effectively reduce energy consumption.Fire prevention: up to national standard or class A.Clean and environmental protection: no two pollution will be caused by air.
Q:Coke burns in a closed house. Will anyone suffocate in it?
Coke incomplete combustion can produce colorless gas carbon monoxide toxic odor. Carbon monoxide is a harmful gas. It will enter the body in the blood and hemoglobin, hemoglobin can combine with oxygen, cause the body tissue hypoxia, which causes the body to suffocation.
Q:What's the difference between refractory bricks and insulating bricks?
Insulation brick mainly is used to heat, reduce heat loss, refractory brick is mainly used to withstand flame burn. Bricks usually do not contact fire directly, while refractory bricks usually contact the flame directly.
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:What materials are used for roof insulation
The other one is inorganic insulation materials, such as Portland, rare earth insulation, the thickness should be 5 cm or more, up to the high cost of auxiliary materials of construction, to reinforce, new inorganic insulation material, the material thickness, on the line of 2-3 cm, direct smear on the top of the house, without auxiliary material, than the price of wool, high aluminum silicate cotton.
