Problems solved by technology

Although the quality of ultra-flat glazed tiles is better than that of full-polished glazed tiles, there are still phenomena such as poor transparency and three-dimensionality, poor color development, many bubbles, and poor gloss. These deficiencies cannot meet the needs of consumers.

Embodiment 1

[0042] Obtain ultra-flat glazed tiles according to the following preparation method:

[0043] 1) forming the green body, drying the green body at 105°C for 90 minutes to obtain a dried green body;

[0044] 2) Apply an underglaze to the surface of the dry body to obtain the first green brick; the flow rate of the underglaze is 4.77g / s, the specific gravity is 1.89g / ml, and the application amount of the underglaze is 590g / m 2 The fineness is 0.3% by weight of dry material after passing through a 325 mesh sieve;

[0045] 3) Ink-jet printing on the bottom glaze of the first brick to obtain the second brick; during ink-jet printing, the parameters of the ink-jet machine are: the belt speed of the ink-jet machine is 20m / min, and the printing size is 910×910mm; The preset pattern is divided and printed on the 12 first bricks (when the 12 first bricks are paved together, a background wall with a complete pattern can be obtained), and the adjacent first bricks are at the joint Set re...

Abstract

The invention provides a super-flat glazed brick. The super-flat glazed brick comprises a blank body and a glazed layer, wherein the glazed layer is attached to the upper surface of the blank body; the glazed layer comprises ground glaze and surface glaze; the surface glaze is located on the ground glaze; the thickness of the ground glaze is 0.1 to 0.8 mm; the thickness of the surface glaze is 0.5 to 1.0 mm; the ground glaze and the surface glaze are both prepared from specific ingredients. The super-flat glazed brick provided by the invention is high in Mohs hardness, large in breaking strength and low in water absorption.

Description

technical field [0001] The invention relates to the technical field of tiles, in particular to an ultra-flat glazed tile. Background technique [0002] Glaze is a colorless or colored glassy thin layer covering the surface of ceramic products. It is made of mineral raw materials (feldspar, quartz, talc, kaolin, etc.) and chemical raw materials in a certain proportion (some raw materials can be made into frits first) After being ground to make a glaze slurry, it is applied on the surface of the green body and calcined at a certain temperature. After the glaze is fired in the kiln, it is tightly attached to the porcelain body, making the porcelain dense, soft and lustrous, and impermeable to water and air, giving people a bright and mirror-like feeling. At the same time, it can improve the strength and chemical stability of the product, prevent pollution, facilitate cleaning, and reduce corrosion. [0003] Glazed bricks refer to bricks whose surface has been glazed. Glazed ...
