Furnace transmutation decoration glazed brick and production technology

Abstract

The invention relates to a furnace transmutation decoration glazed brick and a production technique thereof. The furnace transmutation decoration glazed brick is prepared from the following componentsin percentage by weight: 10-30% of albite, 3-10% of spodumene, 5-10% of kaoline Al2O3.2SiO2.2H2O, 8-30% of zinc oxide ZnO, 3-10% of talc 3MgO.4SiO2.H2O, 0-20% of titanium TiO2, 3-10% of zirconite ZrSiO, and 1-10% of coloring metallic oxide MnO2, V2O5, Fe2O3 and CoO2. The production technique of the furnace transmutation decoration glazed brick comprises the following steps: (1) shaping the substrate of the furnace transmutation decoration glazed wall and floor bricks; (2) decorating the wall and floor brick substrate surface or anti-abrasion transparent glaze layers and drying; and (3) sintering the furnace transmutation decoration glazed wall and floor bricks once in a high-temperature roller kiln.

Description

technical field [0001] The invention relates to a kiln-changing decorative glazed brick fired on a large scale in a roller kiln and a production process. Background technique [0002] With the application of new technology, new materials and new equipment in the ceramic industry, new products continue to emerge; in the field of decoration of ceramic wall and floor tiles, printing, seepage and multi-tube fabric decorative tiles have greatly enriched the market of ceramic wall and floor tiles; it should be seen These products all rely on the collocation of glaze color or powder color, and produce pattern effect through multi-color printing or multi-tube cloth, and its pattern is single, lacks the change of color. Kiln-changing glaze and crystalline glaze are traditional decorative glazes, which are changed in the kiln by increasing the firing temperature, prolonging the holding time and slow cooling during the firing process to make patterns and crystalline flowers formed by c...

AI Technical Summary

Problems solved by technology

Its shortcoming is that adding low-temperature lead-containing frit into the kiln-changed glaze means that for ceramic tile products, the wear resistance and chemical corrosion resistance of the glaze surface will deteriorate, so that the range of use of ceramic wall and floor tile products will be limited. restricted

Its shortcoming is that the glaze is fired twice, and the heating time of the firing is at least 12 hours, and the cooling is natural cooling. It is a kiln decorative art glaze in the traditional sense. This glaze cannot be applied to the modern production process of wall and floor tiles.

[0005] 200610098258.5 (main classification number: C04B41 / 86) discloses a "ceramic red kiln-changing glaze and its application method". The base glaze has a strong fluxing effect, which lowers the initial melting point of the glaze water, resulting in premature sealing of the glaze surface, making it difficult for the gas to be discharged during the oxidation process of the base glaze. In addition, due to the decrease in the overall temperature of the glaze water, glaze bubbles are prone to occur in the high temperature stage. Defects such as pinholes, in order to solve the above problems, the present invention adopts the method of selecting the base material, and obtains a bright red kiln variable glaze with a smooth glazed surface and stable firing through an orthogonal test.

Its shortcoming is that it uses low-quality porcelain clay and secondary clay as the main raw materials, and is fired in a reducing atmosphere for 8 hours by adding iron-titanium oxides and rare earth metal oxides.
