Product Description

Mullite Insulation Brick

 

Mullite Insulation Brick/Low thermal conductivity/High temperature resistance/Good chemical stability/ Low heat fusion/Non-toxic, no corrosion, green environmental protection

 

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.
