Method and equipment for making magic coloured polished bricks

Abstract

By use of special blanking mechanism, many colored additional powder materials together with the main powder material are laid down on the blanking mechanism, then they are pushed to a pressing machine under the feeding mechanism to be pressed into blank body which is dried, calcined, polished into glazing brick products. Advantages include pattern close to natural stone, colors possessing obvious boundaries and also color with transition from natural boundary, color difference not easy to be produced in prodn. process, and high prodn. efficiency.

Description

Technical field: [0001] The invention relates to a method and a device for manufacturing polished tiles, in particular to a method and a device for manufacturing polished tiles imitating natural stone. Background technique: [0002] There are three kinds of existing manufacturing methods of floor tiles imitating natural stone: [0003] One is the overglaze printing method, that is, a layer of glaze is applied on the surface of the polished brick body, and then the pattern of natural stone is printed, and finally it is fired at a high temperature. The surface color of the polished brick produced by this method is close to natural Stone, but its wear resistance and texture are far from natural stone. [0004] The second is the seepage method, that is, the pattern of natural stone is printed on the surface of the polished brick body with water-soluble mineral pigments. In this way, under the action of water penetration, the water-soluble mineral pigments penetrate below the su...

Problems solved by technology

[0003] One is the overglaze printing method, that is, a layer of glaze is applied on the surface of the polished brick body, and then the pattern of natural stone is printed, and finally it is fired at a high temperature. The surface color of the polished brick produced by this method is close to natural Stone, but its wear resistance and texture are far from natural stone

[0004] The second is the seepage method, that is, the pattern of natural stone is printed on the surface of the polished brick body with water-soluble mineral pigments. In this way, under the action of water penetration, the water-soluble mineral pigments penetrate below the surface of the polished tiles to form a thin surface. A layer of patterns, and then fired and polished, this kind of polished tiles is affected by the limitations of mineral pigments, the color of the finished product is relatively monotonous, and defects such as color difference are prone to occur during the production process

This kind of method is complicated in technology and low in production efficiency. The surface pattern separation lines of the polished tiles produced are obvious, and the transition between patterns is relatively rigid. Moreover, the fixed pattern is simply repeated between bricks, which is not natural enough.
