METHOD FOR MANUFACTURE OF LAYER PRODUCTS OF BULKY DISCONTINUOUS CONFIGURATION Russian patent published in 1995 - IPC

FIELD: manufacture of filter elements. SUBSTANCE: applied to network base by spraying with air stream are powders containing, at least, 5% of ductile metals or their alloys. These powders are accelerated by air flow to velocities exceeding minimal ones at which adhesion interaction of particles of applied material with material of network base is started. In so doing, base and air flow are oriented relative to each other depending on preset configuration of product and cells in it. EFFECT: higher efficiency. 3 cl, 4 dwg
