infrared cordierite honeycomb ceramics porous gas burner
Reputation depends on quality, quality comes from Hard!
Honeycomb ceramics are a new type of ceramic product with a honeycomb shape. It is widely used in the chemical, electric power, metallurgy, petroleum, electronic appliances, machinery and other industries for the first time in the purification of small vehicles. It is more and more extensive and the development prospects are considerable.Honeycomb ceramics are composed of numerous equal pores. The maximum number of holes has reached 120-140 per square centimeter, the density is 0.3-0.6 grams per cubic centimeter, and the water absorption rate is up to 20%. Due to the characteristics of porous thin wall, the geometric surface area of the carrier is greatly increased and the thermal shock resistance is improved. The products are meshed with triangles and squares, the triangle is much better than the square, and the number of holes is much larger. This is especially important as a catalytic carrier. As the number of holes per unit area increases and the thickness of the carrier wall decreases, the thermal shock resistance of the ceramic carrier increases, and the temperature of thermal shock damage also increases.
The pressure resistance is 280 to 500 MPa.
The tensile strength is 25 to 40 MPa.
The bending strength is 50 to 60 MPa.
The impact strength is 1.8 to 2.2 cm·kg/cm 2 .
Linear expansion coefficient (1.1 to 1.8) × 10-6 (20 to 100 ° C).
The average thermal conductivity is 3.35 to 5.02 kJ/(m2·h·°C) (0 to 100 ° C).
Resistance to hot and cold temperatures of 300 to 500 ° C.
The insulation resistance is 2.3 to 5.6 MΩ·cm (400 to 600 ° C).
The dielectric loss tangent value was 200 × 10 -4 (50 Hz); 40 × 10 -4 (500 Hz).
The degree of refractoriness is about 1400 ° C.
When used as a catalyst carrier, honeycomb ceramics are mainly used in automobile exhaust gas purification, boiler exhaust and denitrification (NOx), industrial exhaust gas deodorization, and removal of toxic and harmful gases.
The honeycomb ceramic catalyst carrier for automobile exhaust gas purification is mainly a cordierite honeycomb ceramic carrier coated with γ-Al 2 O 3
2. Refractory kiln
The quality of extruded honeycomb ceramic kiln furniture is 60%-75% lighter than that of traditional kiln furniture. The heat transfer is rapid and can be quickly burned. When it is used to burn ferrite or other electronic ceramics, it is beneficial to improve the performance of the product. 
3. Wall flow filter
The porous thin-walled honeycomb ceramic can filter and purify carbon particles in the diesel exhaust gas (about 500 ° C).
