Ceramic tile made from desulfurized residues and glaze residues, and production method of ceramic tile

Abstract

The invention discloses a ceramic tile made from desulfurized residues and glaze residues. The ceramic tile comprises, by weight, 1-5% of mixed waste residues and 95-99% of base materials; the mixed waste residues comprise, by weight, 75-90% of the waste glaze residues and 10-25% of the desulfurized residues; the waste glaze residues are produced in the production process of ceramic tiles, and thedesulfurized residues are produced through flue gas desulfurization by lime water. The invention also discloses a production method of the ceramic tile. The ceramic tile and the production method thereof have the advantages that the waste glaze residues and the waste residues generated by flue gas desulfurization are introduced to a basic formula, so that the desulfurized residues and the waste glaze residues are recycled, and each performance of the product reaches the standard; the desulfurized residues and the waste glaze residues are recycled, so that waste discharged from production of the desulfurized residues and the waste glaze residues is avoided, the production cost of the ceramic tile can be reduced, and the quality of finished ceramic tile products is not affected.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a ceramic brick using desulfurization slag and glaze slag as raw materials and a production method thereof. Background technique [0002] The flue gas of spray drying tower and kiln in ceramic tile production contains high SO 2 Direct emission of acidic gases such as SO will seriously pollute the air, and environmental protection agencies at all levels have 2 There are strict detection mechanisms and control standards for the emission of polluting gases, so desulfurization is an important part of the environmental protection treatment of building ceramics. Lime (CaO) is a simple and effective method of desulfurization, the production of calcium hydroxide (Ca(OH) 2 ), sprayed in the chimney in the form of water curtain, SO 2 Acid gas and water are fused to produce sulfurous acid (H 2 SO 3 ), sulfurous acid (H 2 SO 3 ) and lime water (Ca(OH) 2 ) undergoes a chemical reacti...

AI Technical Summary

Problems solved by technology

Although the waste glaze slag has the properties of glaze, it is mixed with other components, so it is difficult to be used in the production of high-quality antique brick products in the form of glaze

The firing temperature of waste glaze slag is low, there are many raw materials for low-temperature melting, high-temperature melting degree and low high-temperature viscosity. It is directly applied to the blank to increase the amount of liquid phase when the blank is fired, and it is difficult to control the brick shape and wave pattern of the kiln.

[0004] In the prior art, desulfurization slag and waste glaze slag are often treated as production waste, which is difficult to recycle
