Ceramic Fibre Board   ( Polishing & Non-polishing) 

 

     JiuQiang ceramic fibre  boards are rigid products made from ceramic fiber which is vacuum formed with organic and inorganic binders, with or without mineral fillers. These are manufactured over a wide range of grades densities and hardnesses.

     The boards are featured with high temperature stability, low thermal conductivity, even density, and excellent resistance against thermal shock and chemical attack. They can be used as individual component of furnace linings or as hard hot face layer as backup insulation.

 

Product Advantages

* Low heat storage and low thermal conductivity

* High compression strength

* Non –fragile materials and good toughness

* Accurate dimension and good planeness         

* structure homogeneity and easy machining

* Easy to install

* Continual production, even fiber with stable property

* Excellent heat stability and thermal shock resistance

 Typical Application

* Industrial furnace wall lining and bricking-up insulating layer

* kiln lining, kiln cars, door baffles, kiln furnace dividers of high temperature kiln

* Heat insulation, fireproof and sound insulation of aerospace, shipbuilding industries

*Combustion chambesr of boilers & heaters
* Hot face lining for furnaces & kilns
* Backup insulation to castable & bricks
* Ladle covers, Aluminium trough liners, Trough covers, Expansion joints, Hot gas duct linging, Riser sleeves, Crucibles, Launders, Tap out cones, Sight holes etc
