Hitech thermal refractory ceramic fiber blanket for fire resistance
1. Description
Ceramic fiber blanket is made by special ceramic long-fiber, which
is produced by melting very pure raw materials and needling in
double surface.Ceramic fiber blanket also named aluminum silicate
fiber blanket, because their main component is aluminum. It’s a new
type of fire-resisting and heat-insulating materials with white
color and accurate dimension.
Ceramic fiber blanket is also called Aluminum silicate ceramic
fiber blanket.
Aluminum silicate ceramic fiber blanket offers 5 standard grades of
spun ceramic fiber blanket,it is completely inorganic and is
available in a variety of densities, thicknesses, widths and
temperature ratings, all of which are lightweight and thermally
efficient, resulting in a material that possesses the advantages of
low heat storage and complete resistance to thermal shock.
Used in a variety of heat processing applications, the ceramic
fiber blanket is produced from high strength spun ceramic fibers
and is needled to provide exceptional handling strength.
Ceramic fiber blanket does not contain any adhesive to ensure their
stable performance in high temperature or low temperature
environment.
Their Classification Temperature: 1050-1600°C.
2. Characteristics
Low thermal capacity, low heat conductivity
Non-brittle material, good elasticity
Good wind erosion resistance performance, long service life
Excellent thermal stability and thermal shock resistance
Good Sound-absorbing performance
Rigid, self-supporting plate
Good anti-strip performance
Easy molding and cutting
3. Features
- Low heat strong capacity, Low thermal conductivity
- Excellent thermal stability and shock resistance, resist
devitrification at high temperature
- Excellent tearing resistant
- Excellent insulating performance, fire prevention and sound
absorption
- Double—side needling operation produces tough, resilient and strong
blankets, which resist tearing both before and after heating.
- Easy cutting and installation
