Problems solved by technology

[0002] With the improvement of people's quality of life and the change of aesthetic views, ceramic tableware is used more and more widely in life, but ceramic tableware will crack and lose porcelain when it is slightly bumped during use, and it will be damaged during the long-term washing process. A large number of scratches will be produced in the bowl, and the color will be deepened, thereby affecting the use of ceramic tableware and shortening the service life of ceramic tableware; at present, in order to improve the strength of ceramic tableware, research is carried out on the raw material ratio of the blank body, which has not yet appeared in the blank.

Embodiment 1

[0015] A firing method for improving the strength of a ceramic tableware body, comprising the following steps:

[0016] (1) Initial firing: Place the ceramic tableware green body in the kiln, raise the temperature to 240°C at a rate of 0.4°C / min, keep it warm for 30 minutes, and naturally cool to 50°C to obtain the initial firing body;

[0017] (2) Spray treatment: Spray the surface treatment liquid evenly on the outer surface of the first-fired billet, and the spray volume is 1.1ml / cm 2 , stand still for 60min to get the spray-treated green body; the surface treatment liquid is made up of the following raw materials in parts by weight: zinc sulfate 16, nano silicon dioxide 10, sodium perborate 5, water 400; the surface treatment liquid The preparation method is to add nano-silica to water, ultrasonicate at 45°C and 31kHz for 20 minutes, then add zinc sulfate and sodium perborate, raise the temperature to 60°C, keep stirring for 10 minutes, and cool down naturally to obtain a ...

Embodiment 2

[0023] A firing method for improving the strength of a ceramic tableware body, comprising the following steps:

[0024] (1) Initial firing: Place the ceramic tableware green body in the kiln, raise the temperature to 250°C at a rate of 0.6°C / min, keep it warm for 30-40 minutes, and cool it naturally to 60°C to obtain the initial firing body;

[0025] (2) Spray treatment: Spray the surface treatment liquid evenly on the outer surface of the first-fired billet, and the spray volume is 1.2ml / cm 2 , stand still for 75min to get the spray-treated green body; the surface treatment liquid is made up of the following raw materials in parts by weight: zinc sulfate 17, nano silicon dioxide 11, sodium perborate 6, water 450; the surface treatment liquid The preparation method is to add nano-silica to water, ultrasonicate at 48°C and 32kHz for 25 minutes, then add zinc sulfate and sodium perborate, raise the temperature to 65°C, keep stirring for 15 minutes, and cool down naturally to obt...

Embodiment 3

[0031] A firing method for improving the strength of a ceramic tableware body, comprising the following steps:

[0032] (1) Initial firing: Place the ceramic tableware green body in a kiln, raise the temperature to 260°C at a rate of 0.8°C / min, keep it warm for 40 minutes, and cool it naturally to 70°C to obtain the initial firing body;

[0033] (2) Spray treatment: Spray the surface treatment liquid evenly on the outer surface of the first-fired billet, and the spray volume is 1.3ml / cm 2 , standing still for 90min, to get the spray-treated green body; the surface treatment liquid is composed of the following raw materials in parts by weight: zinc sulfate 18, nano silicon dioxide 12, sodium perborate 7, water 500; the surface treatment liquid The preparation method is to add nano-silica to water, ultrasonicate at 50°C and 33kHz for 30 minutes, then add zinc sulfate and sodium perborate, raise the temperature to 70°C, keep stirring for 20 minutes, and cool down naturally to obt...

Abstract

The invention mainly relates to the technical field of ceramic processing and discloses a firing method for improving the strength of a ceramic dinnerware body. The firing method comprises the following steps: primary firing, spraying treatment, second-time firing, third-time firing and cooling. The firing method for improving the strength of the ceramic dinnerware body, provided by the invention,has the advantages that the method is simple and the prepared ceramic dinnerware body has the advantages of high strength, smooth surface, high wear resistance, convenience for applying glaze and high practicability; a ceramic dinnerware green body is put into a kiln; after the temperature is slowly raised, the ceramic dinnerware green body is fired, so that moisture in the body is slowly volatilized; no bubbles are generated on the body so that the body is dense and uniform and is fine and smooth, and the strength of the body is remarkably improved; after the primary firing is finished, a surface treatment solution is uniformly sprayed on the outer surface of the body, and possible residual gaps on the surface of the body are filled, so that the strength and wear resistance of dinnerwareare improved.
