Process of making stone-imitating ceramic tile

Abstract

The process of making stone-imitating ceramic tile includes the following steps: flow casting several ceramic color pastes in different colors in some carrier, pre-drying to obtain color paste adobe of certain water content, pressing inside a mold in a press, stoving, calcining and polishing. Pressing after pre-drying can ensure high density, fine and flat surface of product and the aesthetic sense similar to that of natural stone material.

Description

technical field [0001] The invention relates to a production method of wall and floor tiles, in particular to a production method of imitating natural stone ceramic wall and floor tiles. Background technique [0002] At present, the production of imitation natural stone (marble) ceramic wall and floor tiles is developing in the direction of better simulation and more natural stone texture. Specifically, in terms of craftsmanship, liquid fabric layout is used to replace powdery fabric. , Chinese Patent Publication No. CN1603141 and Publication No. CN1544262A respectively disclose a "manufacturing process for ceramic polished tiles with natural stone texture" and "a production method for imitating polished natural marble". The color paste is then dried and fired, while the latter is based on the former casting paste, using "multi-tube extrusion paste distribution machine with color paste or bell glaze pouring machine or grouting machine to put color on the mud base Formed as ...

[0002] At present, the production of imitation natural stone (marble) ceramic wall and floor tiles is developing in the direction of better simulation and more natural stone texture. Specifically, in terms of craftsmanship, liquid fabric layout is used to replace powdery fabric. , Chinese Patent Publication No. CN1603141 and Publication No. CN1544262A respectively disclose a "manufacturing process for ceramic polished tiles with natural stone texture" and "a production method for imitating polished natural marble". The color paste is then dried and fired, while the latter is based on the former casting paste, using "multi-tube extrusion paste distribution machine with color paste or bell glaze pouring machine or grouting machine to put color on the mud base Formed as a mud base with a layer of color paste layer on it", the above two technical solutions all have common deficiencies, which are specifically manifested in that the color paste that is spread on the brick adobe, because its entire shape is fluid , the density of the fluid is relatively evacuated, and the density of the slurry is different in one part. Due to the above reasons, defects such as pores, shrinkage, and deformation often occur on the surface of the brick during the firing process, which affects the quality of the brick. overall processing quality
