Problems solved by technology

The disadvantage of these two methods is: because the flower paper will be folded when it is pressed by the concave-convex mold surface, it will cause defects on the concave-convex surface of the green body, and it is difficult to meet the production requirements.
The concave surface of natural stone with a concave-convex surface is often different in color from the convex or flat surface. When using the above-mentioned prior art to produce ceramic tiles with a concave-convex surface, it is difficult to realize that the concave surface of natural stone is different from the convex or flat surface, and the pattern is continuous. , Ceramic tiles without flower defects

example 1

[0012] Firstly, the blank, glaze a, and glaze b are prepared. Glaze a and glaze b are glaze slurry prepared by mixing with water. Glaze a and glaze b have different colors or textures after being fired in a kiln. In the production line of ceramic printed tiles that generally have forming presses, dryers, glazing equipment, glaze grinding equipment, flat screen printing machines or roller printing machines, and kilns, the blanks are first pressed into ceramics with a concave-convex surface by a forming press. After the green body is dried by a dryer, the glazing equipment applies a certain thickness of glaze a on the surface of the green body for the first time with wet glazing, and then applies a certain thickness of glaze b for the second time. The glaze applied for the first time can be thinner For some, the glaze applied for the second time can be thicker. After the glaze surface dries up, use glaze grinding equipment to smooth the entire glaze surface, so that the concave s...

[0014] First prepare the blank and glaze a. Glaze a is the glaze slurry prepared by mixing water. The blank is formed into a blank with a concave-convex surface. A certain amount of glaze a is applied to the concave-convex surface of the blank by wet glazing, and the blank is dried. The glaze on the surface of the body, and then smooth the glaze surface, according to the unevenness of the surface of the body, the curvature of the concave-convex surface, and the size of the concave-convex surface, so that the concave area of ​​the glaze surface that has not been ground is compared with the concave surface of the concave-convex surface of the body. The area can be reduced by more than 50% or more than 60% or more than 70% or more than 80% or more than 90% or more than 95%. According to the design requirements during printing, the entire glaze surface can be printed on flowers or more than 70% Flowers can be printed on the concave surface of the unground glaze surface or more than...

Abstract

The invention discloses a concave-convex superficial ceramic tile production method and the produced ceramic tile. The method comprises the production of the concave-convex superficial semi-finished body, the glazing of the semi-finished body surface, the rubdown of the glazed surface, the printing decoration and the sintering. The invention is characterized in that the area of the unpolished glaze surface is reduced by more than 50 percent compared with the concave area of the semi-finished body before glazing after the rubdown. The concave-convex superficial ceramic tile production method not only overcomes the insufficient inflorescence of the concave area, but also realizes different effects of concave and convex or plane color or tactile sensation. Moreover, the invention has the advantage of low cost compared with the prior art.

Description

technical field [0001] The invention relates to a method for producing ceramic bricks with concave-convex surfaces and the produced ceramic bricks. Background technique [0002] The general production method of ceramic printed tiles includes preparing the green body, applying glaze on the surface of the green body, plane screen printing or roller printing, and finally firing. When using this method to produce ceramic tiles with a concave-convex surface, since flat screen printing or roller printing cannot print the decal glaze on the concave part, the ceramic tiles produced by this method usually only show the color of the top glaze on the concave surface. However, if the printed pattern is not used, the continuous pattern on the screen or the drum will be broken or blank at the concave surface, resulting in a defect called lack of flowers, which cannot achieve the design effect and affects the appearance of the brick. The methods provided by the existing decoration technol...
