Title:
ANTIMICROBIAL METALLIC FILTER AND ITS MANUFACTURE
Document Type and Number:
Japanese Patent JPH09131506
Kind Code:
A
Abstract:

To provide an antimicrobial metallic filter having high performance by forming a porous metallic sintered body which has a composition consisting of silver or a silver alloy, etc. on the surface of a metallic substrate.

In this manufacture, as a substrate made of copper, a copper alloy or stainless steel, or the like, a mesh or perforated plate is used. Then, a composition consisting of a water-insoluble hydrocarbon based organic solvent having 5 to 8 carbon atoms, a surfactant, a water soluble resin binder, a silver or silver alloy powder and/or a copper or copper alloy powder and water, is formed into a body on the surface of the substrate and then, the formed body is dried and sintered to form a porous metallic sintered body 3 consisting of silver or a silver alloy and/or copper or a copper alloy, each of which has antimicrobial activity, on the surface of the substrate. At this time, the specific surface area of the sintered body 3 is adjusted to ≥50m2/kg.
