Method for manufacturing anti-microbial glass particles

1 . A method for manufacturing anti-microbial glass particles, which comprises the steps of:

melting, breaking or pulverizing anti-microbial glasses or known substances for forming anti-microbial glasses resulting in a prepared composition of anti-microbial glass;

putting the prepared composition of anti-microbial glass in an extruder;

putting an additive selected from the group consisting of heavy metals and anti-microbial effective substances into the extruder, where the additive is melted or smelted and mixed with the prepared composition of anti-microbial glass resulting in a melted anti-microbial glass mixture; and

cooling the melted anti-microbial glass mixture resulting in an anti-microbial glass mixture, and after cooling the additive mixed in the anti-microbial glass mixture being crystalline or in an original condition, and the additive being enveloped and evenly distributed in the anti-microbial glass mixture.

2 . The method according to claim 1 , which further comprises grinding the anti-microbial glass mixture containing the additive in the crystalline or in the original condition and being enveloped and evenly distributed in the anti-microbial glass mixture.

3 . The method according to claim 1 , which further comprises foaming up the melted anti-microbial glass mixture with the addition of the additive resulting in an anti-microbial foamed glass, and, after the cooling, the additive in the anti-microbial foamed glass being in the crystalline or in the original condition and enveloped and evenly distributed in the anti-microbial foamed glass.

4 . The method according to claim 3 , which further comprises adding additional substances for facilitating the foaming of the melted anti-microbial glass mixture to the melted anti-microbial glass mixture having the additive present therein in the crystalline or in the original condition and enveloped and evenly distributed in the anti-microbial glass mixture.

5 . The method according to claim 3 , which further comprises adding gaseous substances for assisting in the foaming up of the melted anti-microbial glass mixture having the additive present therein in the crystalline or in the original condition and enveloped and evenly distributed in the anti-microbial glass mixture.

6 . The method according to claim 3 , which further comprises adding foam-forming substances to the melted anti-microbial glass mixture for initiating the foaming up, by a change of an aggregate condition, of the melted anti-microbial glass mixture having the additive present therein in the crystalline or in the original condition and enveloped and evenly distributed therein.

7 . The method according to claim 3 , which further comprises adding one of chemical compounds and chemical elements as foam-forming substances which initiate a gas formation by a chemical reaction and, subsequently, initiating the foaming of the melted anti-microbial glass mixture for foaming up the melted anti-microbial glass mixture containing the additive present in the crystalline or in the original condition and are enveloped and evenly distributed therein.

8 . The method according to claim 3 , which further comprises adding foam-forming substances as a solution, emulsion or mixture to the melted anti-microbial glass mixture containing the additive in the crystalline or in the original condition and enveloped by and evenly distributed in the anti-microbial glass mixture.

9 . The method according to claim 3 , which further comprises: treating the melted anti-microbial glass mixture with an additional additive selected from the group consisting of heavy metals and anti-microbial effective substances;

foaming up the melted anti-microbial glass mixture resulting in the anti-microbial foamed glass, and, after cooling, the additional additive in the anti-microbial foamed glass is present in crystalline or in original condition and is enveloped and evenly distributed; and

grinding up the anti-microbial foamed glass.
