Light Weight Mullite Insulation Brick
The light weight mullite insulation brick is a kind of insulation
material adopting organic matter as ignition loss substance in
order to increase the porosity of refractory, which has such
advantages as high porosity, small volume density, good insulation
effect, high mechanical intensity, small thermal conductivity and
long service life. For various industrial kilns & furnaces, it is a
kind of essential refractory for energy saving and temperature
preservation
Light Weight mullite Brick Feature:
1. Low bulk density, low thermal conductivity, good thermal
insulation performance.
2. Refractory category allow direct contact of fire, suitable ofr
various atmosphere
3. Good integrity with furnace lining, long service life, easy
operation, could be shaped freely
4. Product specification: standard form, normal standard, shaped
and special shaped bricks.
5. Can be used in various kilns because of its cheapness and
general tray package. Among all of the refractory materials, it is
the most widely used.
