Embodiment 1

[0067] A method for processing ceramic products, comprising the steps of:

[0068] (1) blank processing and blank forming processing,

[0069] Including crushing and sieving blocky solid materials to obtain granular raw materials; followed by iron removal, mud dehydration, aging, mud refining, and granulation to obtain a billet with particle gradation and good fluidity;

[0070] Form the blank into the shape of a ceramic product, then use mixed abrasives to spray the surface of the blank at high speed, and then dry it to obtain a green body;

[0071] The mixed abrasive includes a mixture of aluminum oxide, silicon oxide, diamond powder and glass powder, each raw material component is ball milled and passed through a 1100 mesh sieve, and the mass ratio of aluminum oxide, silicon oxide, diamond powder and glass powder is 1 :0.3:1.4:0.6;

[0072] The conditions of the high-speed spraying include: using nitrogen as the carrier gas, the output of the mixed abrasive is 65g / min, th...

Embodiment 2

[0080] The processing method of ceramic products as provided in Example 1, the difference is that in step (1), in the mixed abrasive, the mass ratio of aluminum oxide, silicon oxide, diamond powder and glass powder is 1:0.2:1.2:0.4 ; All the other remain unchanged, and the ceramic product is obtained according to the processing method of Example 1.

Embodiment 3

[0082] The processing method of ceramic products as provided in Example 1, the difference is that in step (1), in the mixed abrasive, the mass ratio of aluminum oxide, silicon oxide, diamond powder and glass powder is 1:0.5:1.5:0.9 ; All the other remain unchanged, and the ceramic product is obtained according to the processing method of Example 1.

Abstract

The invention belongs to the technical field of ceramics, and particularly relates to a high-strength ceramic product and a processing method thereof. The processing method comprises the following steps: (1) treating a blank material, forming and processing a blank body, forming the blank material into the shape of the ceramic product, performing high-speed spraying on the surface of the blank body by adopting a mixed grinding material, and then performing drying treatment to obtain a green blank; (2) preparing a glaze material; (3) performing glazing treatment; and (4) firing and forming. According to the high-strength ceramic product and the processing method thereof, the surface which is formed initially by the blank material is subjected to high-speed spraying treatment by utilizing the mixed grinding material, so that the compactness of the formed blank material surface can be further improved through the mixed grinding material which is sprayed at a high speed, and then the mechanical strength of the ceramic product after being fired and formed is improved; moreover, inorganic non-metal components contained in the mixed grinding material can be adhered to the structure surface of the blank body and can be integrated with the ceramic blank body in a firing process. Therefore, a surface structure with high strength is obtained.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to a high-strength ceramic product and a processing method thereof. Background technique [0002] In the traditional concept, ceramics are artificial industrial products based on inorganic non-metallic minerals such as clay. It includes various products made of clay or a mixture containing clay after mixing, forming, and calcination. It ranges from the roughest earthenware to the finest fine pottery and porcelain. Its main raw material is silicate products obtained from nature, such as clay, quartz and so on. With the development of science and technology, many new ceramic varieties have emerged in recent years. They no longer use or rarely use traditional ceramic materials such as clay, feldspar, and quartz, but use other special raw materials, and even expand to non-silicic acid. The scope of salt, non-oxide, and many new processes have emerged to process it, so the...
