Expanded Vermiculite Gasket Alumina Ceramic Foam Filter Plate For Aluninum Liquid Filtration

Alumina Ceramic Foam Filter Plate can effectively remove all kinds of inclusions with fineness up to micron level in aluminum liquid, make aluminum liquid into a steady laminar flow, which is conducive to filling. 

● It has a unique mullite-corundum structure, good mechanical strength and chemical stability, excellent resistance to aluminum liquid erosion performance.

● It can obtain stable filtration effect by strict control of hole size and through hole rate.

● It is surrounded by a sealing ceramic fiber liner, which facilitates the seal of the filter plate in the filter box to ensure that there is no metal liquid sideflow.

Mainly used in the purification process of aluminum and aluminum alloy production, but also used as a variety of gas-solid, liquid-solid separation media, catalyst carrier, burner and sound absorption and environmental protection fields.

The other applications of Alumina foam ceramic filter plate:

1. Copper alloy casting filtration,

In the casting process of Non-ferrous metal melt (brass, bronze, zinc, tin) also will generate oxidation, non-metallic debris and a large number of waste products. It can greatly reduce the rate of scrap if use foam ceramic filter plate. 1.0 ~ 1.2mm mesh with cordierite material is best choice for the filtration of copper alloy.

2. Catalyst carrier for vehicle exhaust purification processor,

The foam ceramics have been widely used as the carrier of automobile exhaust catalytic purifier because of its large surface area, good thermal stability, wear resistance, resistance to poisoning and low density. 

The foam ceramic automobile exhaust catalytic purifier installed in the exhaust pipe of the gasoline car can make the harmful gas CO,HC,NOx discharged from the gasoline car into CO2, H2O,N2, the conversion rate can reach more than 90%; Used in diesel vehicles, carbon particle purification rate in more than 50%. When the foam ceramic filter element is full of carbon particles, catalytic oxidation method or electronic combustion method can be used to regenerate, constantly eliminate the deposited carbon particles, to achieve the purpose of long-term use.

3. In special fields,

The other applications under high temperature conditions, foam ceramics have excellent thermal radiation characteristics, which are used to enhance heat transfer and combustion technology in porous media with remarkable results. 

Foam ceramic can also be made into a photocatalyst carrier, coated with nano titanium dioxide on the foam ceramic carrier, excited by ultraviolet light, has strong photocatalytic oxidation and degradation characteristics, can catalyze the degradation of organic matter and microorganisms, so as to purify the air.

Foam ceramics can also be made into chemical tower packing, gas distribution materials, gas stove energy-saving combustion plate.

Today, two pallets of such Alumina Ceramic Foam Filter Plates are exported to Brazil, U.A.E. and Canada.
