Abstract
A dry granular ceramic tile from a wet slurry spraying process and a preparation method thereof, comprises: applying an overglaze on a green body, applying a pattern by ink-jet printing, applying a dry granular glaze by bell-shaped spraying, and sintering to obtain ceramic tiles. The dry granular glaze contains: by mass percentage, dry granular frit A: 15%, dry granular frit B: 12% to 15%, dry granular frit C: 13% to 17%. The softening temperature of the dry granular frit A is 1135° C. to 1175° C., 980° C. to 1050° C. for the dry granular frit B, and 1020° C. to 1127° C. for the dry granular frit C. The dry granular frits used in the present invention adopts a combination of dry granular frits with three different melting points, and using such a matching method, it is convenient for the effective adjustment of the brick shape and the firing temperature during production.
