Ceramic Fiber Board
Being a prominent ceramic fiber products producer and exporter in India, we are using refractory fibers and binders for producing our Ceramic fiber board.DCW Ceramic Fiber Board is made of ceramic bulk fiber with a specially formulated binder and produced by vacuum-formed technology. The board has excellent toughness and intensity, high strength, lightweight, excellent thermal shock resistance, and anti-stripping.
DCW Ceramic Fiber Board can be widely used for insulation in the linings around and at the bottom of kilns, as well as ceramic kilns fire position, craft glass mold, and other positions. Temperature varies from LT1050℃(1930°F), RT-1260⁰C (2300°F), and HTZ-1425⁰C (2600°F). It is available in a wide variety of thicknesses, widths, and densities.
Characteristics
- Low heat storage, and low thermal conductivity.
- Non-brittle material, good elasticity.
- High compressive strength &temperature stability.
- Excellent wind-erosion resistance, and long service life.
- Excellent thermal stability and thermal shock resistance.
- Continuous production, even fiber distribution, and stable performance.
- Good sound insulation.
- Good anti-stripping properties.
- Easily molded or cut, easy to install.
- Accurate sizes and good flatness.
Applications
- Refractory lining.
- Insulating backup to dense refractory materials.
- Insulating backup to brick & castable.
- Furnace hot face lining in a ceramic kiln, box furnace & petrochemical furnace.
- Use in industrial heat processing equipment.
- Rigid high-temperature gaskets & seals.
- High-temperature baffles & muffles.
- Flue & chimney linings in furnaces & kilns.
- Molten metal trough covers.
- Hot gas duct linings.
- Expansion joints.
- Industrial heat shields & thermal barriers.
- Industrial combustion chamber construction.
- Domestic appliance & light-duty industrial combustion chamber construction.
