General information:

Cmax ceramic fiber blanket is made from high quality gao-ling clay, high purity alumina and silica oxides by spun or blown process. It is asbestos free. No chemical binder is added. Double-size needling provides blanket with great tensile or handling strength for easy installation. Blankets are available in various classified temperature from 1260ºC to 1430ºC.

Cmax ceramic fibre blanket is resistant to most chemicals attack except hydrofluoric phosphoric acid and high pH alkali(na2o or k2o). Its thermal and physical properties can not be affected by oil, steam and water, very good thermal insulating materials.

Advantages:
Heat reflectance
Light weight
Low thermal conductivity
Low heat storage
Flexible
Resilient to thermal stock
High tensile strength
Corrosion resistance
Easy to install
Asbestos free

Application:
Petrochemical process heater refractory fiber lining
Heat treating furnace or intermittent (shuttle) kiln hot face lining
General furnace backup insulation
Heat seals for kiln car or furnace door
Electrical insulator
High temperature acoustic
Fire protection

Non-standard sizes are available upon request.

Q: What are the main components of refractory bricks: Mainly is magnesium oxide, sodium silicate as a binder

Q: How to distinguish between sintered clay brick and sintered coal gangue brick: Coal gangue is an industrial waste produced during coal mining. Using coal gangue as raw material for the production of new wall materials, both to protect the ecological environment, but also save the land, save energy, it meets the development policy of wall materials industry in China, is a new wall material attaches great importance to and vigorously support the development of the.

Q: What are the weak points of clay bricks?: In the temperature range of 0~1000 DEG C, the clay brick volume increases with temperature uniform expansion, linear expansion curve approximates a straight line, the line expansion rate is 0.6%~0.7%, about half of the brick. When the temperature reaches 1200 degrees Celsius and then continues to heat up, the volume will begin to shrink from the maximum expansion. The residual shrinkage of clay brick results in the cracking of masonry joints, which is a major drawback of clay bricks. When the temperature is above 1200 degrees, the low melting point of the clay brick gradually melts because the particles are very close to each other due to surface tension, resulting in volume shrinkage.

Q: Does circulating fluidized bed boiler's furnace wall use refractory to have thermal insulation?: Now all use castable refractory, the outer layer is generally pouring refractory castable, the inside layer is a heat insulation castable refractory.

Q: Can common cement mortar be used to build the lining of chimney refractory brick?: No. You have used fire bricks, which shows there is a certain temperature inside, you'd better use refractory cement

Q: Do refractory bricks need to be sent to the lab to test after arriving the site?: Yes, need to test physical and chemical indicators

Q: Can thick steel plate be used instead of the furnace inside the refractory brick?: It depends on the temperature. The steel plate is a kind of heat conduction material which hasn't heat insulation, which should be based on the working environment.

Q: Do slag bricks have clay bricks strong enough?: Clay bricks you mean should be red bricks burned out of the fire.

Q: What are the physical and chemical properties of refractory bricks: The thermal shock stability, linear?change?on?reheating, softening temperature under a fixed load, compressive strength under normal strength refractoriness

Q: Can porous clay bricks be made of 12 walls to bear weight?: With the production of low energy consumption, convenient construction and waste utilizing, light weight, high strength, good insulation effect, durability, low shrinkage, regular appearance and other characteristics, is an ideal material to replace sintered clay brick.
