Patent

CA 2460740

The invention provides a method to transform large quantities of waste glass into useful ceramic products by a low-cost manufacturing process. The method improves green strength compared to previous methods, and does not require water or any other liquid solvent. Only one firing step is needed with a low peak firing temperature of about 700~C to about 1000~C. The method conserves energy and natural resources compared to clay-based traditional ceramic manufacturing. High-quality impervious ceramic products can be produced by the invention.

L'invention concerne un procédé de transformation de quantités élevées de déchets de verre en produits céramiques utiles par un procédé de fabrication à faible coût. Ce procédé permet d'améliorer la résistance à cru par rapport aux procédés précédents et ne nécessite pas l'utilisation d'eau ou de n'importe quel solvant liquide. Seule une étape de cuisson est nécessaire à une faible température de cuisson de pointe de l'ordre de 700 à 1000 ·C environ. Ce procédé permet de conserver de l'énergie ainsi que les ressources naturelles par rapport au procédé de fabrication de céramique traditionnelle à base d'argile. Le procédé selon l'invention permet également de fabriquer des produits céramiques étanches et de qualité élevée.
