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.

- Inquire about price/MOQ

Q:What is the exterior wall insulation material made of graphite?
Graphite is polystyrene board, polyurethane graphite plate, from the point of view of building the acceptance specification in the use process, the core index of insulation material is the heat transfer coefficient and safety, by now a large number of glazed hollow bead slurry from the actual situation it seems difficult to ensure the quality of construction materials should be on site workers slurry mixing, finished product the quality gap made out of very large.
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:The insulation layer destroyed after use of cement paste and tiling
Attach tiles directly to the insulating layer. But one requirement is to check the insulation process in the balcony of your house. Usually wall - insulation layer - galvanized wire mesh - cement mortar, scraping - paint. If the lack of process fill such as galvanized mesh, remove paint, and tiling. You can use high mark cement or direct adhesive.
Q:Which kind of balcony heat preservation material is better?
To environmental protection, then use inorganic insulation materials, such as composite silicate, rare earth insulation, this thickness should be more than 5 cm, the construction of auxiliary materials, high cost, to be strengthened
Q:Masonry method for boiler refractory brick
Ash bucket (including inclined wall masonry):(1) and an ash bucket masonry first according to drawing find horizontal center line, with the horizontal center line to find out the ash bucket longitudinal center line, coarse slag bucket at the outside edge of the straight wall before and after, based on both ends of the facade vertical center line to pop up the bottom of the ash bucket, ash bucket with bottom opening size of pillar, pop-up vertical auxiliary line using triangle pattern production (according to the drawings, the inclination of inclined wall making) inclined wall paintings in the ends of the facade of the sideline. Use the same material to make refractory concrete inclined wall bottom of the triangle from Taiwan (Figure 1) and straight wall leveling, vertical and horizontal, inclined wall at the junction of the triangle from Taiwan, with the same material refractory concrete filling, until the final setting of concrete masonry wall inclined rear can.(2) and an ash bucket masonry masonry masonry, the first transverse longitudinal component after; inclined wall and straight wall, first built after the straight wall masonry wall.(3), on the back of a foundation by inclined wall, brick and mortar foundation contact surface to be full; inclined wall on the back fill cinder, corresponding to the 2~3 layer of brick masonry masonry, each high, fill a cinder cinder, must reinforce.
Q:Is it necessary to abolish the technical regulations for the construction of self thermal insulation masonry building with sludge sintering insulation bricks?
The original "technical specification for self insulation masonry building with silt insulation bricks" has been replaced by DGJ32/TJ78-2009 (technical specification for automatic insulation wall system of sintered silt non bearing insulating brick) DGJ32/TJ78-2013.
Q:Refractory bricks, burner bricks, insulation bricks? Is it a kind of thing?
Not the same thing, refractory bricks and insulation bricks of raw materials, the proportion is not the same. This is the chain of various types of products
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 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.
