Product Description

Ceramic Honeycomb Filter

Ceramic honeycomb filters are mainly used in metallurgy and foundry industries. The product has the characteristics of a large surface area, high mechanical strength, and good thermal shock resistance. Its main materials are mullite, cordierite ceramics, Corundum-mullite, alumina, and so on. Mullite-based ceramic materials can withstand severe pouring thermal shock and extreme pouring temperature. The honeycomb design also provides an engineering balance between flow rate and strength. The honeycomb ceramic filter has precise dimensions, good thermal stability, high specific surface area, and excellent resistance to acids and alkalis. It is suitable for a wide range of filtration applications of ferrous and non-ferrous metal castings.
By using Al2O3, it independently developed a pore filter with a pore density of 400 pores per square inch, compressive strength> 20 mPa, and porosity> 20%. The shape of this filter includes spherical, polygonal, and mesh partitions. Because this filter has strong corrosion resistance, high adsorption rate, no shedding, and enhanced durability, it has been favored by European and American customers for many years and is used as a carrier for desulfurization and denitrification catalysts in the petrochemical industry.

Physical characteristics:
Main material: Mullite, SiO₂
Working temperature: ≤1520ºC
White color
CSI (number of units per square inch): 50/100/200/300
Porosity (%): 35-60
Compressive strength (Mpa): ≥20 (room temperature)
Bulk density (g/cm3): 0.8-1.2
Thermal shock resistance: ≥2 times / 1100ºC-normal temperature
Size: length (diameter) * width * thickness = (37-150) * (37-150) * (8-25) mm
Shape: circle, square and rectangle
Dimension tolerance: -1mm~1mm

Feature:
*Purify metal liquid, absorb oxides, and filter non-metal impurities
*Make the metal liquid flow at a stable speed, reduce eddy currents, and reduce bubbles in the casting
* Balance phase structure and extend tool life
*Improve the surface properties of castings and increase the density of castings
Good thermal shock performance
The uniform round holes avoid small eddies and turbulence when the molten metal passes through.
The precise extrusion die makes the quality of the ceramic honeycomb filter extremely stable and consistent

Application range:
*As a catalyst carrier, ceramic honeycomb materials are usually used to purify automobile emissions and eliminate odors.
*As a heat exchange medium, ceramic honeycomb material is mainly used in the heat recovery unit of RTO, not ceramic saddle
*Ceramic honeycomb material is used as the filtrate matrix, usually used in food processing, water treatment, environmental industry, metallurgical industry, etc.
