FILTERING MEDIUM COMPRISING MINERAL FIBRES OBTAINED BY MEANS OF CENTRIFUGATION

摘要

The fabrication of a filtering medium incorporating a mineral fibre felt linked to a voile comprises: (a) formation of fibres using an internal centrifuging device comprising a fibre forming spinner; (b) spraying a precursor of a binder onto the fibres; (c) positioning the fibres on the voile; (d) heat treating the assembly following a controlled thickness to transform the binder precursor into a binder. Independent claims are also included for: (a) a filtering media fabricated by this method; (b) a bag filter using this filtering medium.
