A kind of manufacturing method of non-smoked salt glaze ceramics

Abstract

The invention discloses a method for manufacturing non-smoked salt glaze ceramics, which changes the smoking of gaseous salt vapor into liquid ion penetration, including the following steps: 1) slurry mixing: adding alkali metal salts to the glaze slurry, mixing thoroughly and fully dissolving ; 2) After glazing, drying and firing. The present invention adopts the production method of ordinary ceramics to produce salt-smoked glazed ceramics, does not generate alkali metal salt vapor in the process of manufacturing salt-smoked glazed ceramics, does not pollute the environment, reduces the firing temperature so as to save energy, and the product maintains the characteristics of salt-smoked glazed pottery, A thicker vitrified layer is formed in the green body, and there is no glaze crack or leakage.

Description

technical field [0001] The invention belongs to the field of ceramic production, in particular to a method for manufacturing non-smoked salt-glazed ceramics. Background technique [0002] Salt glaze is smoked glaze, also known as condensation glaze. It is to use salt gas to penetrate into the green body and react with the green body at high temperature, so that the green body is vitrified, and a glass covering layer, that is, a glaze layer, is formed on the surface. At present, the production method of salt glaze is mainly to add salt in the high temperature stage of firing to generate salt vapor, the capillary pores of the green body absorb the salt vapor, the salt ions interact with the green body to make it vitrified, and the surface of the green body interacts with the salt vapor to form Glazed surface, glazed surface and vitrified layer as a whole, no glaze crack, no leakage. Since table salt needs to be heated to produce salt vapor, the vaporization temperature of ta...

AI Technical Summary

Problems solved by technology

Since table salt needs to be heated to produce salt vapor, the vaporization temperature of table salt is around 1300°C, so the firing temperature must be above 1300°C, which consumes a lot of energy; and when firing, the excess salt vapor fills the kiln and emits outward or passes through the chimney It is discharged with flue gas, pollutes the atmosphere, and is difficult to control, which seriously restricts the production of this type of product
