Product Description:

Refractory Light Brick Thermal Insulating Fire Brick


 

High alumina insulating fire brick is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory, which has such advantages as high porosity, small volume density, good insulation effect, high mechanical intensity, small thermal conductivity and long service life. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.

This series of High Alumina Insulating Fire Brick are made of selected high alumina bauxite, kaolin caly, hollow microsphere as the mian material.By shaping at high pressure and sintering at high temperature. 

 

Product Applications:

High alumina insulating fire brick are ideal for use in the below applications 

Building materials for blast furnace

Building materials for hot-blast stove

Building materials for coke oven

Building materials for steel making furnace

For construction material in steel industry

For ladle

 

Product Advantages:

CNBM has success in its High alumina insulating fire brick due to their cost-effectiveness and excellent insulating properties. The refractoriness of magnesia chrome bricks are more than 2000°C, and the refractory under load is a above 1550°C.Good steady volume in high temperature, the performance of meeting sudden cold and sudden hot is better than magnesia bricks. 

 

Main Product Features:

Excellent thermal stability

Q:The structural specification does not indicate that masonry needs insulation bricks. Is it necessary to use insulation bricks?
Under normal circumstances, the use of thermal insulation brick experience in construction drawings marked, if there is no relevant description requirements, then do not use insulation bricks.
Q:How much is a thermal brick
Insulation brick prices also have a great relationship with the material and workmanship, such as clay brick price is much lower than high alumina brick, mullite and corundum brick prices will be higher.
Q:What are the types of building blocks?
1. the use of the different parts, building bricks into bricks, floor brick, brick, brick arch shell, brick brick chimney and sewer.2. different building performance, building bricks into bearing brick, brick, brick, non bearing engineering insulation brick, brick, tile, acoustical tile and other flowers.The use of 3. different materials, is divided into building brick clay brick, shale, coal gangue brick, fly ash brick, slag brick, lime sand brick etc..4. according to the shape, the building brick can be divided into solid brick, microporous brick, porous brick and hollow brick. Ordinary bricks and special-shaped bricks, etc..
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 maximum temperature range of high temperature resistant insulation materials?
A class of inorganic non-metallic materials with a refractoriness of not less than 1580 degrees. Refractoriness is defined as the temperature of a sample of a refractory cone sample that resists high temperature without loading and does not soften and melt down. But only in terms of fire resistance can not be fully described refractories, 1580 degrees of temperature is not absolute.
Q:How to reinforce a porous brick foundation?
Increase depth method: for immediate lower layer is a good soil bearing situation, while the best bearing layer in groundwaterBit line above.
Q:There are several construction techniques for exterior wall insulation
Exterior wall sandwich insulation technologyThe exterior wall sandwich insulation is to place the heat preservation material between the inner and outer wall sheets of the outer wall, and the inner and outer walls can be made of concrete hollow blocks.Advantage:1) to the inner wall piece and the heat preservation material forms the effective protection, to the heat preservation material selection material request is not high (source: Chinese heat preservation net), polystyrene, glass cotton and urea aldehyde field casting material and so on may use;2) the construction season and construction conditions are not very high, and it does not affect the winter construction. In Heilongjiang, Inner Mongolia, northern Gansu and other cold areas have been given some applications.Shortcoming:1) in non cold areas, this kind of wall is thicker than traditional wall;2) the inner and the outer wall pieces need to be connected by connecting pieces, and the structure is more complicated than the traditional wall;3) periphery structure of "bridge" more. In the earthquake zone, building circle beam and constructional column settings, "bridge" more efficiency of thermal insulation materials is still not fully play.4) outside the walls by the outdoor climate, the temperature difference between day and night and the large temperature difference between summer and winter, easy to cause the wall cracking and leakage of rainwater.
Q:Can the whole wall of the high-rise building be made of grey insulation bricks?
As can be seen from the picture, the aerated concrete block should be 200MM thick. According to the regulations, it is possible because the building is a frame structure.
Q:Advantages and disadvantages of external formwork and self thermal insulation block
Exterior wall internal insulation technology, wall insulation is to heat insulation materials on the inside of the outer wall.Advantage:1) waterproof, weather resistance and other technical indicators of finishes and insulation material requirements are not very high, gypsum board, gypsum plaster mortar can meet the use requirement, convenient;2) the internal insulation material is separated by the floor slab and is only constructed within a high storey without scaffolding;3) in the hot summer and cold winter and hot summer and warm winter zone, the inner heat preservation can meet the requirement;4) for the existing buildings of energy-saving transformation, especially at present when the house sold to individuals, the whole building or the whole district unified transformation difficulties, only the possibility of internal insulation. Therefore, in recent years, the exterior wall insulation has also been widely used.Shortcoming:1) because of beam, slab, structural column will cause thermal bridges, more heat loss;2) due to the material, structure, construction and other reasons, the cracking of the facing layer;3) it is not convenient for users to decorate two times and hang ornaments;4) occupy indoor use space;5) the energy saving of the existing buildings is very disturbing to the daily life of the residents.6) wall under outdoor climate, the temperature difference between day and night and the large temperature difference between summer and winter, easy to cause the wall cracking.
Q:What are the sizes of lightweight thermal insulation bricks?
Low iron mullite, high aluminum light insulating refractory brick, diatomite insulating refractory brick. Sizes can be customized for ordinary profiled sizes
