Production method of once-fired super-spar ceramic tile and ceramic tile

Abstract

The invention relates to a production method of once-fired super-spar ceramic tile and the ceramic tile. The production method of the once-fired super-spar ceramic tile comprises the following steps: preparing green body powder; pressing a tile body; cleaning the green body; pouring ground glaze; printing; pouring overglaze; firing a glaze body at a high temperature; polishing; performing surface treatment; performing edge polishing; and packaging to obtain a finished product, wherein the overglaze comprises the following components in parts by weight: 5 to 13 parts of quartz powder, 3 to 20 parts of potassium feldspar, 20 to 28 parts of soda feldspar, 12 to 18 parts of dolomite, 3 to 6 parts of fired talc, 3 to 8 parts of kaolin, 14 to 22 parts of calcined kaolin, 3 to 8 parts of zinc oxide, 7 to 14 parts of barium carbonate and 3 to 6 parts of grammite. According to the invention, the problems that microlite has low wear resistance and is difficult to process in the prior art are solved, and the defect of water ripples caused by the situations that fully-polished glaze absorbs dirt, bottom is easy to expose and the tile surface is uneven is also solved. The super-spar product produced with the method has the advantages that the microlite is transparent, bright and smooth like a mirror and does not absorb dirt completely; and the fully-polished glaze is light, thin and wear-resistant.

Description

technical field [0001] The invention relates to the technical field of architectural ceramic glazed porcelain tiles, and more specifically, relates to a production method of one-time firing supercrystalline ceramic tiles and ceramic tiles made by the method. Background technique [0002] As a product of new technology, polished glazed ceramics can show rich and colorful decorative effects such as magnificence, freshness and elegance, or antique flavors better than traditional polished tiles, and are more and more recognized by consumers. Among them, there are The two products of special significance are called microcrystalline stone (also called microcrystalline glass-ceramic composite board) and full polished glaze in the industry. At present, most of the production process of microcrystalline stone is a two-firing process. It is necessary to sinter the adobe first, then apply glaze to the surface of the adobe, and then glaze and fire; there are also some manufacturers such...

AI Technical Summary

Problems solved by technology

As far as microcrystalline stones are produced by the above two processes, the products obtained have defects such as excessive thickness, poor wear resistance, and difficult processing. They are limited to home or wall decoration and are not suitable for large-scale promotion.

Although the current fully polished glaze is slightly thinner than microcrystalline stone and has better wear resistance, it still has problems such as dirt absorption, easy bottom exposure, water ripples caused by uneven brick surfaces, etc.
