Product Description

Ceramic honeycomb filter apply to metal liqiud filtration. With high achievable surface areas, low thermal expansion, excellent thermal shock resistance and high compressive strength. Ceramic filter is widely used in foundry industries of steel, iron, aluminum and copper etc. It is made of cordierite-mullite, and designed with parallel channels and with high porosity. It has the features of strong mechanical strength, good thermal shock performance and fast casting filling time. The utilization of ceramic filter can remarkably increase the casting quality.

Function:
*Mechanic deterring: Remove big oxide
*Commutated function: Calm down turbulent laminar flow
*Absorbing function: The myriad eyelets which only been found in microscope can absorb smaller impurities, make more excellent metal products.
*Contact action: The special exact square and the triangle bore eye apperance design promote to oxidize miscellaneous quality to absorb dintfe.

Feature:
Honeycomb ceramic heat accumulation substrate has low heat expansion coefficient, large surface area, good heat stability and anti-corrosion.

Application:
*Purification system in the smoke of the thermal power plant.
*Harmful gas purification system in rubbish burning.
*Toxic gas purification system in chemical and mining industries.
*Slag filter in casting and foundry industry.
*Catalyst substrate, stuffing material for chemical industry columns and contact combustion.

Ceramic honeycomb filter has the following characteristics:
*Low pressure drop
*Excellent chemical and thermal durability
*Good thermal shock resistance
*High geometric surface area
*Low expansion coefficie

Advantages:
Catalyst carrier: It can clean waste gas
Heat transfer agent: It can save 12% of energy in heat exchange
Refractory stove: Low mass/volume, fast heat conduction
Gas burn distributing plate: Complete burn, energy saving is 10%
