Problems solved by technology

[0002] Ceramic products are calcined at a temperature above 500°C from the embryo body made of traditional mud formula, which has many shortcomings. The ceramic products made of ceramic products have low density, high water absorption, and are prone to leakage, deformation, glazed surface, and Defects such as pinholes, thin glaze, and shrinkage glaze, and most of the properties of the current blank are not suitable for mechanized assembly line production, resulting in low quality and high production costs, which cannot meet the cultural needs of multi-level and multi-field consumer groups for ceramic products
For example, ceramic wine bottles belong to the category of packaging containers, which have high requirements for product density, color, strength, water absorption, and size. Therefore, the existing materials of ceramic products cannot meet the production requirements of ceramic wine bottles.

Abstract

The invention relates to a ceramic preparation method, in particular to a high-dense low-water-absorption ceramic product. The high-dense low-water-absorption ceramic product is prepared from ingredients of cream-colored mud, intercalated mud, washed kaolin, feldspar, titanium dioxide, iron oxide red, talc, kibushi-clay, barium carbonate, sodium humate and sodium silicate. The color of a carcass is pure and united, and the color of the sintered carcass is bluish yellow touched with red, and is simple, unsophisticated and elegant; the ceramic preparation method is suitable for mechanized flow line production; the biscuit firing temperature can be adjusted according to needs; the obtained ceramic product has the characteristics of being high in compactness, low in water absorption rate, high in strength, corrosion-resistant and leakage-resistant, high in heat stability, and free of deformation and cracking; the glaze surface of the glazed product is smooth and clean, the water absorption rate is 0.2 part or below, and the appearance exquisite degree of a ceramic container is improved; the ceramic preparation method is suitable for high-grade ceramic products such as high-grade ceramic wine bottles.
