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 price of concrete self insulation bricks
If you really want to buy thermal insulation brick, do not simply look at the price, but also to consider the quality of the product. (a piece of brick in the market basically in 6 yuan, if there is a floating price if it is because of the size of the insulation brick or distance, but floating slightly.)
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 a heat insulating brick?
You can go to the construction site to see if there are grey, hollowed out bricks, basically.
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:How to do indoor thermal insulation
Indoor thermal insulation, as well as "folk prescription""Some owners also used some of the insulation sleeves, for example, light reflection, heat is also, by means of a reflected heat, indoor temperature increase, the specific approach is adopted, Kouban metal surface, can also use the kitchen stove using metal film or metal film for baking food, installed in the radiator the walls and the walls, so that the heat preservation and reflection cooling effect, but also does not affect the appearance. Again, the 40% heat and window glass heat loss on indoor winter, especially some French families, the feeling of winter indoor temperature is relatively low, methods can be used to paste glass insulation film and coated glass insulation coating to retain heat.
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: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 the price of thermal insulation brick for exterior wall?
Hello, the exterior wall insulation has many practices, useful insulation bricks, but also useful particles of polystyrene insulation mortar mixed (thickness is not the same, the price is not the same);
Q:If there is a main component of cenosphere light insulating brick.
Before 2003 because the price is cheaper to do so cenosphere light heat insulation brick is generally used zeeospheres. After 2003 basically replaced by fly ash and other lightweight refractory material, but some high-grade light brick or floating beads.
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.
