Mullite Insulation Brick
Mullite Insulation Brick/Low thermal conductivity/High fire
resistance/High thermal compressive strength/Excellent chemical
stability and corrosion resistance/Energy saving effect is obvious
Summary:
Mullite Insulation Brick is a kind of high alumina refractory
material with mullite as the main crystal phase, usually alumina
content between 65% and 75%. In addition to mullite, its mineral
composition may also contain a small amount of glass and square
quartz or corundum.
Product features:
- 1. Low thermal conductivity:mullite insulation brick has a good
thermal insulation effect, low thermal conductivity, can
effectively reduce energy consumption;
- 2. High temperature resistance: high fire resistance;
- 3. High strength: high thermal compressive strength, good thermal
shock resistance;
- 4. Good chemical stability: with excellent chemical stability and
corrosion resistance, suitable for a variety of corrosive gases and
liquid environment;
- 5. Low heat fusion: due to the low thermal conductivity, the series
of light insulation brick accumulated heat energy less, energy
saving effect is obvious;
- 6. Environmental protection: non-toxic, no corrosion, green
environmental protection, can be used safely;
Range of application:
- Hot air furnace, hot air curtain machine, all kinds of high
temperature furnace, tunnel kiln and other industrial kilns.
- Blast furnace, hot blast furnace, heating furnace, annealing
furnace, coke oven, incinerator and other iron and steel metallurgy
industry and non-ferrous metal industry furnace.
- Ceramic, glass, cement and other building materials industry kiln
and tunnel kiln.
- Petrochemical industry cracking furnace, converter furnace, heating
furnace, etc.
- Waste incinerators and other industrial kilns.
