Production process of dry grain soft cast ceramic tiles

Abstract

The invention provides a production process of dry grain soft cast ceramic tiles and relates to the technical field of ceramic tile production. The process comprises the following steps: brushing ceramic bodies, spraying water (8-10g per tray), spraying ground coat (1.35 pecific gravity 100g per tray), spraying overglaze (1.45 pecific gravity 40g per tray), performing inkjet printing, spraying a protective layer (1.15 pecific gravity 30g per tray), spraying dry grains by a high-pressure spray gun (1.22 pecific gravity 105g per tray), drying and sintering in a kiln. According to the specific formula process and polishing process, the mean finish degree of the dry grain soft cast process product is 15 degrees only, the problem of visual discomfort is solved, waxing is not needed at the laterstage of polishing, and the cost is saved. The wear resistance of the dry grain glaze is better than that of polished glazed tiles, and the dry grain glaze has advantages in application. The surfacehand feeling of the soft cast product is fine and smooth, and the antifouling property is better than that of semi-polished products.

Description

technical field [0001] The invention relates to the technical field of ceramic tile production, in particular to a production process of dry-grained soft-polished tiles. Background technique [0002] The dry grain soft polishing technology adjusts the glaze formula and polishing process, cooperates with the mold and design, so that the product can achieve the effect of imitating soft smooth stone with soft luminosity, realistic pattern and delicate hand feeling. [0003] The current technology has the following two shortcomings and deficiencies: [0004] First, the semi-polishing process of dry granules is only a glazing on the raised surface of the dry granules, and the surface of the product has only dot-like flashes visually, and the hand feel is not delicate enough. There are too many gaps between the dry granules of the semi-polishing process. In terms of application, the product is easy to hide dirt and is inconvenient to handle. health. [0005] The second is that...
