Product Description:

Introduction of insulating firebrick

Insulating brick is sintered mainly with supper-fine bauxite charlotte and propr additive by a method of EPS ignition loss. Refractory high alumina EPS insulating brick for heating furnace is a kind of insulation refractory product, taking bauxite as main raw material and including not less than 48% of AL2O3.

Characteristics of insulating firebrick

1.High porosity

2.Small volume density

3.Good insulation effect

4.High mechanical intensity

5.Small thermal conductivity

6.Long service life

 

Application of insulating firebrick

1. Building materials for blast furnace

2. Building materials for hot-blast stove

3. Building materials for coke oven

4. Building materials for steel making furnace

5. For construction material in steel industry

6. For ladle

Q:The project cost in hydropower No.3 shaft wall is solid brick or insulating brick?
From the structure principle, hydropower shaft with solid brick, is to consider the safety performance of the structure.
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:Does the building with the exterior wall thermal insulation brick require adding an angle steel bracket in the middle of the brick?
The first thing the man has to do is to do the quality test in front of the wall. As for the second, there is not much to do.
Q:What is the difference between the production line of foamed cement insulation bricks and the self thermal insulation block production line?
Yes, this year's business is not very good to do, customers pay more attention to the quality of products, seven industrial equipment, very satisfied with the service OK
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: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:Energy saving bricks or bricks?
Insulating bricks are mostly hollow or light bricks.It can be said to be energy-saving bricks, including insulation bricks
Q:What are the insulation materials for heating buried pipelines?
The heat preservation layer is composed of antirust paint, heat insulating material, moisture-proof layer (used for pipeline in the trench), protective layer, anticorrosive layer (used for trench or directly buried pipe) and top coat (or fireproof coating).The waterproof layer can be used asphalt or aluminum foil protective layer with glass cloth or galvanized steel.
Q:What materials are used for roof insulation
There are two kinds: one is a kind of cotton insulation board, such as rock wool board, aluminum silicate cotton board, but this is not environmental protection, harmful to life, foam board (this fire safety factor minimum), these relatively cheap.
Q:The insulation layer destroyed after use of cement paste and tiling
The most certain and the method can increase the area of the balcony is to eradicate the insulation layer exposed after cement wall tiles.
