Glazed brick with mirror effect on the surface made of sludge slag and preparation method thereof

Abstract

The invention provides a glazed tile prepared from sludge with mirror-effect surface and a preparation method thereof. The method in the invention, on the basis of no great change of conventional glazed tile production process, exerts key points on formula composition of a green body, compositions of ground and cover glaze clinkers, formula compostion of ground glaze, optimization and proportion of cover glaze clinkers with different performances, and adjustment and selection of formula composition of cover glaze, so the prepared glazed tile has surface glossiness of equal to or more than 90; glaze surface is flat and smooth as a mirror, is glossy and lustrous and is free of defects like pinholes and glaze bubbles; printing pattern of a printing glazed tile is completely deposited into the cover glaze with clear texture, bright color and life-like stone-like texture as if a layer of glittering and transparent glass is covered on the printing pattern; if the glazed tile is erected and the glaze surface faces an object, a shadow of the object in the glaze surface is clearly-visible as in the mirror, and has strong integral art sense; meanwhile, the method in the invention adds a great amount of treated compressed sludge and wastewater generated in every operation procedure in ceramic tile production process into the formula of the green body, so cost is saved, and the purposes of energy conservation and emission reduction are achieved at the same time.

Description

Technical field: [0001] The invention relates to the technical field of preparation of glazed tiles, in particular to a glazed tile with a mirror effect on the surface made of sludge slag and a preparation method thereof. Background technique: [0002] The texture of natural stone is natural and smooth, the color is bright and rich, and the texture of the stone is the same. Therefore, after polishing and polishing, the surface of natural stone is as smooth as a mirror. At the same time, the original color, texture and texture of the stone are not only not damaged, but It is more clear and natural, and the layers are more distinct. The surface is like a layer of transparent crystal glass, which is clear, elegant and magnificent, while ordinary ceramic products will interact with each other during the firing process due to the printing glaze and surface glaze on the surface. Small pits and slight wrinkles are left, and the mirror effect is not as good as that of natural stone ...

Problems solved by technology

[0002] The texture of natural stone is natural and smooth, the color is bright and rich, and the texture of the stone is the same. Therefore, after polishing and polishing, the surface of natural stone is as smooth as a mirror. At the same time, the original color, texture and texture of the stone are not only not damaged, but It is more clear and natural, and the layers are more distinct. The surface is like a layer of transparent crystal glass, which is clear, elegant and magnificent, while ordinary ceramic products will interact with each other during the firing process due to the printing glaze and surface glaze on the surface. Small pits and slight wrinkles are left, and the mirror effect is not as good as that of natural stone after treatment. At the same time, the pattern and texture of these ceramic products cannot be as consistent as stone, so polishing and polishing follow-up treatments cannot be used, otherwise the printed patterns will be damaged. damaged during processing, or even disappear completely

Due to the glaze covered on the printing surface of some glazed ceramic products, it will react with the printing glaze covering the lower surface when fired at high temperature, thus destroying the fine texture of the printing pattern. At the same time, in order to ensure the performance of the product, the covering The glaze on the surface of the printed pattern cannot be as transparent as glass, so it will have a greater impact on the color development of some printed glazes. Therefore, the color of this type of glazed ceramic product is not as rich and bright as natural stone. The texture is not as clear and natural as natural stone
