Problems solved by technology

However, there are also some problems in the application of talc. Adding talc to the porcelain formula will affect the molding rate of the porcelain, and it is easy to generate fire bubbles during the firing process, which will affect the quality of the glaze and reduce the gloss of the glaze. So far, no solution has been found. method, or the effect is not obvious, in order to promote the use of talc in porcelain and make good use of its advantages, it is necessary to provide a technical solution to solve its shortcomings, so as to maximize its strengths and avoid its weaknesses
[0004] In addition, the firing temperature of porcelain is mostly high, all above 1200°C, most of them are as high as above 1400°C, and a lot of energy must be wasted in order to achieve a high temperature firing environment. In order to reduce resource waste and save energy, a kind of porcelain is provided. Reducing the firing temperature is an urgent problem to be solved in the porcelain industry at present.

Abstract

The present invention provides a porcelain formula and a manufacturing process. The porcelain manufacturing process comprises: grinding and mixing raw material components of Longyan clay, bone charcoal, talcum, clay, Mingling mud, sepiolite, Enzhou rare stone powder, feldspar, calcite, flint clay and mineral wool according to a ratio in parts by weight; performing shaping according to a design, trimming a green body, drying the green body, firing the green body in a non-glazing manner at a low temperature of 800 DEG C to 850 DEG C in a reducing atmosphere with 3%-5% CO, and performing polishing for smoothness; and glazing the green body, adding Huiqing, heating and firing the product at 1200 DEG C to 1250 DEG C in a reducing atmosphere with 6%-8% CO. The porcelain provided by the present invention is firm in bonding of raw material components, has an average shaping rate greater than 96%, and is good in whiteness and glaze glossiness. Cracks are effectively prevented, and meanwhile, the blister and deformation phenomena caused by talcum in the porcelain formula are eliminated. In addition, the firing temperature of the porcelain manufacturing process is lowered.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a formula and a manufacturing process of porcelain. Background technique [0002] my country's ceramic industry has a long history and a long history. Most of the raw materials used in pottery and porcelain are natural inorganic non-metallic minerals. These raw materials are processed and refined, compounded, formed, and high-temperature physical and chemical reactions to form a new substance that is completely different from the original composition, that is, ceramics. . The development of my country's pottery to porcelain has gone through three stages: pottery-primitive pottery-porcelain. At present, the raw materials and crafts of porcelain are different. However, there are always some quality problems in the use of raw materials for porcelain. The whiteness and gloss of the glaze are not high, and the yield of finished products is not high. In terms of technology, the firing tempera...
