AdTech specially designed Alumina Ceramic Foam Filters are made of the basic raw material Aluminium Oxide. They are manufactured with porosities varying from 10 to 60 pores per inch (PPI). Also, combo sets are made in 20-30 PPI and other selections are possible. Different sizes and custom-made filters are manufactured according to specifications.<\/p>\n

Features:
\n– A homogeneous pore structure
\n– High surface strength
\n– Temperature resistant up to 1100\u00b0C
\n– Excellent resistance against chemicals used in foundries<\/p>\n

With the development of science and technology, and the improvement of the cleanliness of casting metal alloys, and the improvement of casting performance requirements, a new type of ceramic foam filter has been applied in casting production, which has brought great progress for molten metal filtration.<\/p>\n

The high-quality ceramic foam filter for casting<\/a> plays a very important role in improving the quality of castings. It can effectively filter out the non-metallic inclusions in the molten metal, thereby reducing slag holes, improving the mechanical properties of the castings, and reducing the mechanical properties of the castings, improving the surface finish of castings and prolongs life.<\/p>\n

AdTech foam ceramic filter uses polyurethane foam as a carrier. After hydrolysis, it is immersed in a coating made of ceramic powder, binder, sintering aid, suspending agent, etc., and then squeezed out the excess coating to make the ceramic coating uniform. It is coated on the carrier skeleton to form a green body, and then the green body is dried and fired at a high temperature.<\/p>\n

The filtering effect of the AdTech alumina filters depends on the pore size of the filter plate, the size and type of inclusions (density, wetting characteristics), and the speed of metal aluminum liquid passing through the filter plate.<\/p>\n

Alumina ceramic foam filters are basically divided into pore sizes: 20PPI, 30PPI, 40PPI, 50PPI, and 60PPI. The larger the number, the smaller the aperture. But in actual practice, the four types of 20PPI 30PP 40PPI can meet the needs of customers.<\/p>","protected":false},"excerpt":{"rendered":"
