Abstract

The invention discloses a microcrystal glass ceramic tile and a production method for reducing air bubbles. The production method comprises the following steps of: applying an overglaze and a full-polishing glaze on a raw billet; applying microcrystal dry granules, wherein the microcrystal dry granules have the sieving meshes of 10 to 80, the microcrystal dry granules with the sieving meshes of 10 to 30 account for 40-50wt%, the microcrystal dry granules with sieving meshes of 30 to 60 account for 30-40wt%, the microcrystal dry granules with sieving meshes of 60-80 account for 15-25wt%; applying a fixing agent, and firing once at the temperature of 1,490-1,510 DEG C for 60-80 minutes. Due to the matching of the components and the sieving meshes of the microcrystal dry granules and the set of the firing temperature, the purpose of reducing the air bubbles of the microcrystal glass ceramic tile is achieved, the number of the air bubbles of the microcrystal glass ceramic tile is reduced greatly, the volume is minimized, the microcrystal layer of the microcrystal glass ceramic tile is more transparent, the glaze is clearer, and the quality is improved further.

Description

technical field [0001] The invention relates to the technical field of microcrystalline manufacturing, in particular to a glass-ceramic ceramic brick and a production method for reducing air bubbles in the glass-ceramic ceramic brick. Background technique [0002] Microcrystalline stone, also known as glass-ceramic ceramics, belongs to high-grade decorative materials. Existing microcrystalline ceramic tiles, whether they are first-fired or second-fired, high-temperature fired or low-temperature fired microcrystalline products, all have a large number of bubbles, and the sizes of the bubbles are also different. Very strong. This has seriously affected the aesthetic feeling of glass-ceramic ceramics and reduced the quality of products. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the deficiencies in the prior art above, the object of the present invention is to provide a glass-ceramic brick and a...
