Product Description:

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
CMAX insulating firebricks can be used as a hot face lining directly exposed to the heat or as a backup insulation layer in iron and steel mills, non-ferrous foundries, petrochemical, ceramic, glass.

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:Why does the water drop first and then rise when the boiler fires?
Often in the operation of the boiler, the steam water mixture to the drum after intense evaporation of a large number of bubbles in the water side, the water volume expansion. By actual water level drum water level indicator is higher than the water level
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:What is a JQK composite lightweight thermal insulation brick?
Its characteristic is waterproof and heat insulation, thermal insulation performance, strong decoration, waterproof effect is good, and good weathering resistance, long service life, the whole system of simple construction, low cost, is a new type of inverted waterproof and insulation structure of the current system state key application.
Q:Can activated carbon be antiseptic?
Activated carbon is also called activated carbon black. It is black, powder or lump, granular, cellular amorphous carbon, and also arranged crystal carbon.
Q:Is the quality of brick made of small-sized self insulation block equipment the same as that of large block brick equipment?
Recently, a lot of people have encountered this problem, Silver Horse understand, in fact, the brick machine is only the production of different production, the quality of the bricks produced are the same.
Q:What is composite sintering insulation bricks?
The brick belongs to the porous brick and has good heat preservation performance. Reached the national 50%~65% energy efficiency standards. High safety (no crack, no seepage), strong durability (with building life), economy (self insulation, no need to increase the cost of insulation).
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.
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.
