Abstract

The invention discloses a glazed ceramic tile and a preparation method thereof. The glazed ceramic tile is prepared by processing a blank material and glaze, and the blank material comprises the following compositions in percent by weight: 50-75% of anaerobic digestion sludge, 10-25% of clay, 5-15% of wollastonite, and 5-10% of talcum. The glazed ceramic tile preparation method comprises preparing blank and glaze, forming a green body, drying, biscuiting, glazing the green body, performing glaze firing on the green body, and the like. The green body of the glazed ceramic tile is high in strength and small in shrinkage degree when being biscuited, the biscuiting temperature scope of the green body is expanded, and phenomena that the green body surface foams, generates black hearts and is reduced in compressive strength and the like because of too large ignition loss are effectively avoided. The glazed ceramic tile preparation method enables the glazed ceramic tile surface to be solid, flat, free of black heart phenomenon, and high in strength, and also the preparation method is simple and easily controllable in technology, high in yield and high in production efficiency, and production cost is effectively reduced.

Description

technical field [0001] The invention belongs to the fields of environmental solid waste treatment and building material production, and in particular relates to a glazed ceramic tile and a preparation method thereof. Background technique [0002] Sludge is a by-product of urban water supply and sewage treatment process. Because it contains a large amount of pathogens, heavy metals and various organic pollutants, if it is not treated and discharged randomly, it will inevitably cause serious environmental pollution. How to deal with sludge reasonably and achieve the goal of sludge reduction, harmlessness, and resource utilization has become an environmental problem to be solved urgently by my country's urban water supply, sewage treatment plants and related departments. [0003] Studies have shown that the mineral composition of sludge after dehydration and drying is similar to that of depleted clay resources, and it has certain plasticity, sinterability and heat resistance. ...
