Molten Aluminum Filter PG Foils can effectively remove all kinds of micro-scale inclusions in water. Make the molten aluminum into a stable laminar flow.

Los filtros de espuma cerámica se dividen básicamente en seis tamaños de poro: 10 PPI, 15 PPI, 20 PPI, 25 PPI, 30 PPI y 40 PPI. Cuanto mayor es el número, menor es la abertura. Sin embargo, en la práctica, los cuatro tipos (10 PPI, 20 PPI, 30 PPI y 40 PPI) son suficientes para satisfacer las necesidades de los clientes.

Selección de la apertura
1. El moldeado: 10～25 ppi
2. Colada semicontinua: 30～60 ppi
3. Aluminio o chapa de alta calidad: 50～60 ppp
4. Colada continua y laminación: 50～60 p

With the advancement of preparation technology, ceramics have more new forms, such as porous structures. Porous ceramics have a large number of interconnected pores.
Therefore, porous ceramics have the characteristics of low bulk density, large specific surface area, and low thermal conductivity.
The high specific surface area of porous ceramics makes it have good adsorption capacity and activity.
This can increase the effective contact area and improve the catalytic effect. At the same time, it has the characteristics of thermal shock resistance and corrosion resistance.

Advantages of Molten Aluminum Filter PG Foils
The foam ceramic filter plate for aluminum liquid purification brings great benefits to the peeling foil and its products, such as blanks, car decoration materials, PS printing plates, etc. For aluminum alloy profile manufacturers, the advantages are obvious:
1. Improve the extrusion productivity: when the filtro cerámico is used to purify the alloy extrusion billet, the extrusion speed is increased by about 20%, and the productivity is increased by about 15%.
2. Extend mold life and reduce maintenance times.
3. Low squeezing force: the squeezing force is less than 3% less than the unfiltered one.
4. The surface quality of aluminum profiles is greatly improved.

Ceramic foam filter application
Nowadays, with the improvement of the quality requirements of aluminum products, the application of porous ceramic filters has also been promoted. The porosity of the porous ceramic filter is between 80-90%, which can effectively remove micron-level inclusions. In addition, the ceramic filter plate can also remove harmful elements (Na, K) in the aluminum liquid through adsorption. When filtering aluminum alloy, the filter plate thermally expands instantaneously to ensure that it does not crack when heated.
