Export alumina ceramic foam filter plates to Turkey Clients

Alumina foam ceramic is a kind of foam material made from high purity alumina. The foam ceramics have the characteristics of uniform porosity, high temperature resistance, heat shock resistance, wear resistance and chemical stability.

Widely used in casting processing, water treatment, chemical industry, environmental protection and other industries. 

It is the ideal liquid aluminum filter; Catalyst support, and good sound insulation, thermal insulation material. 

Shapes, sizes, and voids PPI can be designed and manufactured on request.

How to choose the available alumina Ceramic foam filter plate?

First of all, according to the impurity content of aluminum melt, melt transfer flow rate of the final casting product quality requirements.

The plate with a large hole mesh can be chosed when a lot of impurities contained and normal quality of casting products required.

New type plate with small holes can be selected when the quality requirements of casting products are high.

HEBEI CANGCHEN Brand alumina ceramic foam filter plates adopt the organic bubble body with three-dimensional network structure and connected pores as the carrier, which is penetrated into the thixotropic alumina slurry, and adopts the automatic extrusion process with four square correction center distance, so that the slurry is evenly coated on the carrier bubble skeleton, and is roasted at 1180℃ after drying and curing. Installed in the filter box for aluminum alloy liquid impurities filtration, to meet the production of high value-added, high technical performance of aviation, transportation and other aluminum alloy precision casting. Such as: computer hard disk, printing with PS board base, can material, jet turbine engine fan blades and other products, to achieve the ideal cleanliness, to obtain good results.

Depends on the flow rate and total amount of melt through.

Secondly, look at its color, shoot its body, burn its things during select the filter plate.

The color is pure and no impurity that means the material is uniform; The hand is not sticky thatmeans the surface is not sprayed with binder, which will not cause secondary pollution.

Holding the filter plate with one hand and clapping with the other hand, if the ceramic particles continuously drop when beating the filter plate, it means that a poor quality filter plate, which will cause secondary pollution of liquid aluminum.

Use an open flame or electric heating to burn red and make it cooled at room temperature immediately without cracking slag, it is a good filter plate.

Thirdly, The effective specific surface area or porosity calculation of the foam should be carefully evaluated when selecting.

The mesh homogeneity of the surface layer of the filter plate can be observed, and then the mesh homogeneity of the cross section can be observed.

If possible, the porosity can be measured by drainage method.

The three-dimensional mesh is homogeneous, the porosity is relatively large, means it is an excellent foam ceramic filter plate.
