Method for preparing polished crystal tile

Abstract

The invention discloses a method for preparing a polished crystal tile, comprising the following steps of: accumulating a mixture of low-temperature clinkers and high-temperature clinkers on a printed tile surface baked at high temperature; baking; and polishing. The polished crystal tile prepared with the preparation process has high high-temperature viscosity and stable glass network structure, the baked clinker has certain height and has stereoscopic impression and artistic feeling. The action of the skeleton of the high-temperature clinker is favorable to the discharge of bubbles, and the obtained enamel layer has few bubbles, high transparency and high enamel quality. By regulating the proportion of the low-temperature clinkers and the high-temperature clinkers, the preparation method is suitable for different baking temperatures, is convenient and flexible and is suitable for different products.

Description

technical field [0001] The invention relates to a preparation method of polished crystal bricks. Background technique [0002] Polished crystal bricks are crystal clear and have a strong sense of three-dimensionality. Its use enriches the decorative techniques of antique bricks and effectively improves the grade of products. Transparency and gloss are important indicators of crystal polishing frit. The quality of polished crystal tiles depends directly on the quality of the transparent glaze layer. The transparent glaze layer with high transparency and less air bubbles, after polishing, the decorative effect of polished crystal tiles is also better. [0003] The preparation of polished crystal tiles is to apply bottom glaze, surface glaze and printing glaze to the tiles, and then fire them for the first time at 1180-1200°C, and then spread frit dry particles on the surface of the tiles. Generally, the thickness is controlled at about 3mm. It is fired in a kiln at about 95...

AI Technical Summary

Problems solved by technology

[0004] Due to the large accumulation thickness of the frit, it is difficult to exhaust after the frit is melted, so there are a large number of air bubbles in the glaze layer, which seriously affects the transparency of the product. Pores are easy to cause dirt absorption, which seriously affects the appearance and use

At present, a single frit is generally used in the market, resulting in narrow melting temperature, poor adaptability, poor exhaust effect, and more glaze bubbles
