Abstract
A dimensionally stable, flow-porous fluid treatment element suitable for hot fluid treatment, in particular a filter element, characterized by the following components: (a) inorganic solid particles with inner voids; and (b) hardened binder on a water glass base, (c) the binder holding together the solid particles to form the flow-porous fluid treatment element.
Claims14
A dimensionally stable, flow-porous filter element for filtering hot fluid, comprising
- (a) a dimensionally stable, flow-porous molding having the following components:
- foamclay solid particles with inner voids,
- hardened binder on a water glass base, and
- talc as a filler,
- the binder holding together the solid particles to form the flow-porous molding,
- (b) and a surface filtration layer on an afflux surface of the filter element, the surface filtration layer having a smaller pore size than the filter element below the surface filtration layer.
