Ceramic Foam Filters China,Ceramic Fam Filter Manufacturers

When choosing Ceramic Foam Filters China, you should also watch the color, take pictures, and burn the objects.

①The color is pure and free of impurities, indicating that the material is uniform. The hands are not sticky, indicating that the surface is not sprayed with adhesive and will not cause secondary pollution.
②Holding the Ceramic Foam Filters China with one hand and clapping the filter plate with the other hand, the ceramsite slag is continuously dropped, indicating that it is a poor quality filter plate, which will cause secondary pollution of the molten aluminum.
③Use an open flame or electric heating to heat up and burn to red and immediately cool at room temperature without cracking and slag, indicating that it is a good filter plate.

Ceramic Foam Filters China

The effective specific surface area or porosity calculation of the foam should be carefully evaluated when purchasing filtration.

You can observe the uniform state of the mesh on the surface of the filter plate, and then open it to observe the uniform state of the mesh on the section.

If possible, the porosity can be calculated by the drainage method. The three-dimensional mesh is homogeneous and the porosity is relatively large. It is an excellent ceramic foam filters China plate.

The ceramic foam filter series, its three-dimensional connected pores have the following functions for metal solution filtration:

Mechanical screening: remove large particles of mixed oxides and reduce the harm of molten slag to castings.

Filter cake mechanism: The intercepted large particles of mixed oxides gather above the filter to form a filter cake, which increases the ability of the filter to filter small particles of mixed oxides.

Deep adsorption: its unique three-dimensional network structure, with a large surface area, can adsorb fine mixed oxides.

Rectification mechanism: Change the flow of molten metal from turbulent flow to laminar flow, slow down the flow rate, prevent turbulence, reduce sand falling, reduce the secondary oxidation and air suction of molten metal, and improve the performance of castings.

After use:
1. Effectively filter out non-metallic inclusions and sand inclusions in molten metal.
2. Improve the mechanical properties of castings and reduce the wear of machining tools.
3. Simplify the casting system and increase the utilization rate of the template.
4. Conducive to the rapid diagnosis of casting defects.
5. Improve the qualification rate of castings.
6. Improve the metallographic structure of casting products.
