Fabricación de filtros de espuma cerámica de alúmina porosa

Manufacture Porous Alumina Ceramic Foam Filter uses a three-dimensional network structure and an organic foam sponge connected to the pores as a carrier, invading it into a special ceramic slurry with thixotropic properties, and adopting a special roll extrusion process to uniformly apply the ceramic slurry to the skeleton of the carrier.
A continuación, se seca y se solidifica, y después se cuece a alta temperatura.
Filtro de espuma cerámica porosa. Filtros de espuma cerámica para aleaciones de aluminio. Desde que se iniciaron las primeras investigaciones en 1978, la tecnología de filtración con espuma cerámica ha experimentado un rápido desarrollo.
El filtro de espuma cerámica porosa utiliza espuma de poliuretano como soporte, sumergiéndola en un recubrimiento compuesto por polvo cerámico, aglutinante, aditivo de sinterización, agente de suspensión, etc., y, a continuación, extruyendo el exceso de recubrimiento para aplicar de manera uniforme el recubrimiento cerámico sobre el soporte.
El esqueleto se convierte en una masa verde, y esta se seca y se cuece a alta temperatura.

Features of Manufacture Porous Alumina Ceramic Foam Filter
Filtro de espuma cerámica can effectively remove large inclusions in aluminum liquid and adsorb micron-sized fine inclusion particles to improve surface quality, improve product performance, improve microstructure and improve yield.
Se utiliza ampliamente en los sectores de producción de perfiles de aluminio, láminas de aluminio y aleaciones de aluminio.

The Points of Manufacture Porous Alumina Ceramic Foam Filter
Structural characterization of specific reactions in pore size, pore distribution, pore shape and porosity;
The pore structure of the membrane is closely related to its filtration transfer performance.
The pore size and pore size distribution are the most important parameters of the membrane structure, which directly affect the transfer characteristics of the fluid in the membrane and determine the separation and filtration performance of the membrane surface.

The quality of Manufacture Porous Alumina Ceramic Foam Filter in the smelting of aluminum melts is important, which greatly affects the subsequent processing properties and the quality of the final product.
Therefore, all countries in the world attach great importance to the purification of aluminum melt; there are many reasons for aluminum pollution.
On the one hand, during the smelting process, aluminum is exposed to the furnace atmosphere in a molten or semi-molten state, which is prone to oxidation and easily reacts with water vapor. Hydrogen is easy to form various forms of non-metallic slag, as well as coarse intermetallic particles and the like.
On the other hand, part of the waste material in the composition charge carries some non-aluminum impurities during the circulation.
Since the waste comes from the process waste and waste of the various processes of the factory and the waste outside the factory, the route is different, the composition is complex, and the quality is also poor.
Estas impurezas tienden a provocar la formación de burbujas e inclusiones en la plancha, lo que afecta gravemente a la pureza del metal fundido y, por consiguiente, repercute negativamente en las propiedades de procesamiento, las propiedades mecánicas, la resistencia a la corrosión y la calidad estética del producto.

Manufacture Porous Alumina Ceramic Foam Filter can effectively remove all kinds of fineness in the aluminum water to the micron-sized inclusions, so that the aluminum water becomes a smooth laminar flow, which is favorable for filling.
It has a unique corundum structure, good mechanical strength and chemical stability, superior aluminum washability; tightly controlled hole size and through-hole ratio for stable filtration.

Placa filtrante de cerámica is surrounded by a sealed ceramic fiber gasket, which helps the filter plate to seal in the filter box, ensuring no metal loss.
This product is mainly used in the purification process of aluminum and aluminum alloy production.
