Ceramic Foam Filters Production Process, also known as the organic foam impregnation method, is a relatively mature production process.

Sizing process

The selection of the formula must ensure the best condition of the consistency and fluidity of the slurry, so as to ensure that the product can be uniformly sized during the sizing process and achieve the specified sizing weight. Because this is the premise to ensure that the product strength and through hole rate are qualified. The performance of the prepared slurry is judged by its specific gravity and consistency.

Sponge modification process

Sponge modification is to prepare for the sizing process, improve the sizing performance of the sponge, and make the sizing uniform.

Dipping and sizing process

The modified dry sponge product is uniformly coated on the roller press to form a green body through the adjusted slurry. For sponge products with different meshes, different consistency of sizing is required for sizing, otherwise, the sizing effect cannot be achieved.

drying process

The drying process is mainly to let the well-sized semi-finished products volatilize the moisture, generally controlled below 1.0%.

For products with larger specifications, it is necessary to control the dry environment, such as temperature, humidity, etc., to prevent drying deformation and crack defects.

Firing process

The firing process is the last step in the Ceramic Foam Filters Production Process. Due to the improvement of the formula, considering the production cost, most of the foam ceramics in the foam ceramic enterprises do not need atmosphere protection, and the firing temperature is generally 1350. ~1450°C.

AdTech specially designed 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.
