Influence of drying method on the migration of the binder and the properties of a high-temperature filter based on aluminosilicate fibers

Abstract

Ceramic filter elements based on aluminosilicate fibers were produced by vacuum forming, using various drying methods. Microwave drying and freezing followed by drying have been used as methods to reduce binder migration. The microstructure of the obtained filter elements, tensile strength and aerodynamic resistance were analyzed. The obtained characteristics were compared with the characteristics of filter elements made using convective drying. Ill. 6. Ref. 33. Tab.
