A preparation process of kiln-transformed brick with uniform kiln-transformation effect

Abstract

The invention discloses a preparation process of a transmuted tile with a uniform transmutation effect. Chromogenic glaze slip is applied to the surface of a ceramic tile bisque, the surface of a bisque body with a glaze slip layer is dried, and a transmuted tile finished product is obtained by firing. The ceramic tile bisque is prepared from the following raw components in percentage by mass: 50to 60 percent of plastic pug, 10 to 20 percent of clinker particles, 10 to 15 percent of a sandy raw material, 5 to 15 percent of a flux and 0.5 to 2 percent of lithium feldspar. The chromogenic glazeslip is prepared from the following raw components in percentage by mass: 50 to 65 percent of crude ore pug, 4 to 8 percent of rock flour, 6 to 8 percent of fine sand, 6 to 10 percent of a soluble metal salt, 10 to 15 percent of a chromogenic auxiliary and the balance of water. According to the preparation process of the transmuted tile with the uniform transmutation effect, a chromogenic glaze slip application manner is adopted, so that the problem of high occurrence of unstable transmutation effect on the surface of the bisque body is solved, and the yield is high.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a preparation process of kiln-transformed bricks with uniform kiln-transformed effect. Background technique [0002] At present, under the firing conditions of a certain reduction reaction, the brick adobe is usually used to form a kiln effect on the surface of the adobe, so that a certain smoky effect is formed on the adobe, and the decorative effect after paving is realized. The existing ceramic brick plain mud is usually prepared from the raw material components of plastic mud, clinker particles, sandy raw materials, fluxes and pigments. The adobe collapsed and deformed, and even the whole vehicle collapsed. In order to solve this problem, the method of increasing the sand content or alumina content in the raw material of the green body is selected to increase the strength of the green body, or the potassium albite flux is used to reduce the risk of the green b...

Problems solved by technology

[0003] The purpose of the present invention is to propose a preparation process of kiln-changing bricks with uniform kiln-changing effect. By distributing colored glaze slurry, it solves the problem that the kiln-changing effect on the surface of part of the green body is prone to be unstable due to the difficulty of controlling the firing conditions. problem, high yield
