Metal Fibre and Ceramic Fibre Composite Filter Media
topic
Hybrid metal-ceramic filter media combine sintered metal fibre support layers with ceramic fibre filtering layers, exploiting metal fibre mechanical strength and backpulse resistance for structural integrity while ceramic fibre fine pore structure provides high-efficiency submicron particle collection at service temperatures exceeding metal fibre operational limits when ceramic layer faces the high-temperature gas stream.
Role
Extends high-temperature filtration capability beyond the limit of either metal fibre or ceramic fibre alone by combining their respective advantages of mechanical robustness and high-temperature stability in a composite structure where each material layer contributes the property in which it excels, enabling filtration at process conditions inaccessible to either material alone.
