Embodiment 1

[0018] Party:

[0019] 12.5kg of ordinary glass, 30kg of industrial alumina with a purity of 99.99%, 7.5kg of zirconia, 7.5kg of white clay, 7.5kg of potassium feldspar, 15kg of Jingyang clay, and 20kg of kaolin

[0020] Process:

[0021] (1) Take the raw material, add 30% water of the total weight of the raw material to make a slurry;

[0022] (2) The above slurry is ball milled for 10 hours, then the iron is screened out, and the mud is squeezed out. The obtained mud cake is extruded in a vacuum mud refining machine, and the obtained mud section is then subjected to electric shade drying, and finally formed and dried to obtain a green body ;

[0023] (3) After the above-mentioned green body is glazed, fired and glued, it is ready.

Embodiment 2

[0025] 10kg of ordinary glass, 25kg of industrial alumina with a purity of 99.99%, 5kg of zirconia, 5kg of white clay, 5kg of potassium feldspar, 10kg of Jingyang clay, and 15kg of kaolin

[0026] Process:

[0027] (1) Take the raw material, add 20% water of the total weight of the raw material to make a slurry;

[0028] (2) The above slurry is ball milled for 8 hours, then the iron is screened out, and the mud is squeezed. The obtained mud cake is extruded in a vacuum mud refining machine, and the obtained mud section is then subjected to electric shade drying, and finally the green body is obtained after molding and drying ;

[0029] (3) After the above-mentioned green body is glazed, fired and glued, it is ready.

Embodiment 3

[0031] 15kg of ordinary glass, 35kg of industrial alumina with a purity of 99.99%, 10kg of zirconia, 10kg of white clay, 10kg of potassium feldspar, 20kg of Jingyang clay, and 25kg of kaolin

[0032] Process:

[0033] (1) Take the raw material, add water of 40% of the total weight of the raw material, and make a slurry;

[0034] (2) Ball mill the above slurry for 12 hours, then screen out the iron and squeeze the mud. The obtained mud cake is extruded in a vacuum mud refining machine, and the obtained mud section is then dried by electric shade, and finally formed and dried to obtain a green body ;

[0035] (3) After the above-mentioned green body is glazed, fired and glued, it is ready.

Abstract

The invention discloses a high-strength ceramic prepared from glass. The high-strength ceramic prepared from glass is mainly prepared from the following raw materials in parts by weight: 10-15 parts of glass, 25-35 parts of aluminum oxide, 5-10 parts of zirconium oxide, 5-10 parts of white cement gum, 5-10 parts of potassium feldspar, 10-20 parts of Jingyang soil and 15-25 parts of kaolin. The invention further discloses a production process of the high-strength ceramic. Compared with the prior art, the preparation process has the advantages that the firing temperature in the craft process can be remarkably reduced and the mechanical strength of the high-strength ceramic can be remarkably improved. By using glass wastes as raw materials, the high-strength ceramic is low in production cost and easy in process control.

Description

technical field [0001] The invention belongs to the technical field of structural ceramics, and in particular relates to a high-strength porcelain made of glass and a production process thereof. Background technique [0002] With the rapid development of the "Twelfth Five-Year Plan", the electric porcelain industry has also developed rapidly, and the market has higher and higher requirements for high-strength porcelain. One of its indicators - mechanical strength has always been the most important performance pursued by the production of high-strength porcelain in the electric porcelain industry, because when high-strength porcelain has high strength, it can increase the utilization rate of materials, reduce costs, and ensure the reliability of circuits under the same voltage level. safe operation. The original mechanical strength of high-strength porcelain can no longer meet the requirements of the existing market. How to improve the mechanical strength of high-strength po...
