Problems solved by technology

Because the firing temperature of pottery is lower than that of porcelain, ceramic tiles fired at low temperature need to be painted outside the glaze. The patterns formed in this form are easy to wear and damage the picture.
However, if the full glaze is applied after the bottom glaze of the ceramic tile is sprayed, it will cause problems such as easy cracking of the glaze layer and low surface polishing brightness due to the mismatch of expansion coefficients between the glaze layers of the ceramic tile. Due to the low sintering temperature, the color of the spray pattern is insufficient, and the color of the pattern deepens and becomes dark. Cause glaze surface to be porous and uneven

Abstract

The invention relates to a microcrystal mirror polishing wall tile and a manufacturing method thereof and belongs to the technical field of ceramic glazing tiles. The microcrystal mirror polishing wall tile is characterized in that a greenware bottom tile (1) is provided with a glaze surface layer which is formed by applying a ground glaze layer (2), a surface glaze layer (3), an enameling layer (4) and a full-polishing glaze layer (5) layer by layer from bottom to top. The manufacturing method is characterized by comprising the following steps: once firing the greenware bottom tile firstly, and sequentially applying the ground glaze, the surface glaze and the full-polishing glaze on the greenware bottom tile after water spraying; enameling on the surface glaze; and then carrying out secondary firing. According to the microcrystal mirror polishing wall tile disclosed by the invention, as the special constituted surface glaze layer is added, under glaze colors are realized on the greenware bottom tile; as the problem that expansion coefficients among glaze layers of a microcrystal glaze surface of a ceramic green body which is sintered at low temperature are not matched is solved, the glaze surface cannot crack.

Description

technical field [0001] The invention discloses a method for manufacturing microcrystalline mirror-polished wall tiles, which belongs to the technical field of ceramic glazed tiles. Background technique [0002] Ceramic tiles can be divided into two types: porcelain tiles and pottery tiles from the materials used for the bottom blank. Porcelain bricks have high density and high unit volume weight and are generally suitable as floor tiles. Ceramic bricks have relatively low density and small unit volume weight and are often used as wall tiles. In the current technology, the microcrystalline brick is only made by applying the full glaze technique to the brick of the porcelain bottom body. Porcelain tiles adopt a one-time firing process, that is, pile up various glazes and spray patterns on the unfired biscuit and then fire it once. Because the firing temperature of porcelain is relatively high, most of them are above 1200°C, and some even reach around 1400°C. The obtained po...
