Process for manufacturing invisible pattern ceramic product

Abstract

The invention provides a process for manufacturing an invisible pattern ceramic product. The process comprises the following steps: mixing kaolin and water, stirring, standing, clarifying, ball-milling and screening to obtain fine silt, setting the fine silt to obtain a coarse green body, finishing the coarse green body to obtain a green body, preparing glaze water from kaolin, silicon oxide, wollastonite and water, and finishing the green body for performing biscuiting so as to obtain a biscuit; and carving patterns on the biscuit surface, glazing, drying, firing at a high temperature in a kiln, selecting porcelain after delivering out of the kiln, polishing, thereby obtaining the invisible pattern ceramic product. According to the invisible pattern ceramic product prepared by the processdisclosed by the invention, the boundary of the line and the green body is indistinct and partly hidden and partly visible, so that the ceramic product is difficultly discovered by people, can be seen when carefully observed, have a concavo-convex sense when the patterns are touched by hands, has certain wear resistance, thermal stability and water resistance and can be manufactured into ceramictableware, ceramic plates, ceramic tiles, ceramic artwork and other products. The styles of the patterns are changed, and the ceramic product can be endowed with special commemorative significance andvalue.

Description

technical field [0001] The invention belongs to the technical field of ceramic manufacturing, and in particular relates to a process for manufacturing ceramic products with invisible patterns. Background technique [0002] Ceramic products are beautiful in shape, smooth and delicate in hand, clear and bright in color and easy to clean. They have the ability to withstand rapid heat and sudden cold changes of a certain temperature difference and are not easy to burst. It is a poor conductor of heat, heat transfers slowly, and is durable. , salt and carbon dioxide gas in the atmosphere will not corrode, and will not rust and age, so it is very popular among people. Throughout the ages, ceramic makers have engraved patterns on ceramic products, such as flowers, birds, insects and fish, mountains, rivers, sun and moon, or famous poems, which endow ceramic products with different meanings and enhance their connotation and value. After the patterns are engraved on the ceramic prod...

AI Technical Summary

Problems solved by technology

After the patterns are engraved on the ceramic products, the lines and the product itself will have depressions or bulges, which will easily cause the glaze water to gather at the patterns during glazing, so that the glaze layer will be uneven. During the production process, the glaze layer is easy to gather at the pattern after melting, so that the glaze layer is uneven

In addition, when the engraved patterns are shallow, the liquid glaze water will fill the pattern lines during glazing, so that the glazed surface of the pattern will appear smooth and smooth, and the pattern will be easily deformed during high-temperature sintering. As a result, the pattern of fired ceramic products is deformed or even disappears.
