Porous Silicon Ceramic Foam Filter Preparation method
Including ceramic slurry preparation, forming and firing process, which is to add alumina micropowder, bauxite, talcum powder, bentonite in proportion.
The ceramic slurry prepared by using a binder, a dispersing agent and water as a solvent is then sprayed with a polyurethane sponge foam to remove the excess slurry, dried and then fired at a high temperature, and after cooling, an alumina porous foam is obtained. Ceramic filter products.
Porous Silicon Ceramic Foam Filter has excellent high temperature performance and fluid filtration performance, which can be used for the purification of aluminum, aluminum alloy, copper, iron, etc., thereby improving the quality of castings and reducing the scrap rate.
