Heat-barrier material will be 3~4 times.Nanometer heat insulation material uses special nano grade inorganic refractory powder, has huge specific surface
Long-pending, the contact between nano particle is minimum point contact, and the thermal resistance of point contact is very big, so that the conduction heat transfer effect of material
Become very small, causes the conductive heat transfer coefficient of nanometer level microporous heat-barrier material very small；It is formed between nano particle a large amount of
Nanoporous, size is average at 20 nanometers, and the evenly heat freedom of motion journey under the molecule room temperature of still air is received for 60
Rice, is thus locked in air molecule within powder nanometer stomata, so that the small convective heat transfer between still air molecule
Event resolves.Thus the static air of the room temperature thermal conductivity ratio of nanometer micropore heat-barrier material also wants low；At high temperature, heat transfer
Main function is heat radiation, and nanometer micropore heat-barrier material is added to special infrared additive, prevents and reflects red at high temperature
Outer ray bottoms out radiant heat transfer effect, so that the radiation heat transfer coefficient under material at high temperature is reduced to minimum.
In the first incinerator insulating layer refractory lining structure: andalusite brick layer 4 is built by andalusite brick, mullite brick layer
3 are built by mullite brick.
Between andalusite brick layer 4 and mullite brick layer 3, between mullite brick layer 3 and nano thermal insulation plate 2, nano thermal insulation plate 2
It is Nian Jie by adhesive between the inner wall for burning furnace shell 1.It is easily installed operation.

High grade refractory, other than the raw material of technical ceramics industry.Can also smelting high-strength light silicon aluminum alloy, make metallic fiber with
And the guidance type of supersonic plane and spaceship is used.It has been reported that it is external still using mullite carry out coal gasification with
Make radome.A part of well-crystallized, it is bright in colour can also craft articles and ornament.It is opened from the seventies
Begin, andalusite widely paid attention to by China's industrial production, and application field is also expanding rapidly.Andalusite is formed after calcining
Mullite there is very high refractoriness, chemical stability and mechanical strength, therefore obtained in metallurgy, building materials and other industrial departments
To extensive use.
Mullite brick refractoriness is higher, up to 1790 DEG C or more.1600~1700 DEG C of loading softening start temperature.Room temperature is resistance to
70~260MPa of Compressive Strength.Thermal shock resistance is good.There are fused mullite brick and two kinds of electric cast mullite brick.Fused mullite brick with
Bauxite chamotte is primary raw material, and a small amount of clay is added or raw bauxite makees bonding agent, is made through molding, firing.Electric smelting is not
Carry out stone brick using high alumina, commercial alumina and refractory clay as raw material, charcoal is added or coke particulate makees reducing agent, is adopted after molding
It is manufactured with reduction electric smelting method.The crystallization of electrofused mullite is bigger than fused mullite, and thermal shock resistance is better than sintered article.They
High-temperature behavior depends primarily on the content of aluminium oxide and the uniformity of mullite phase and glass distribution.
