Problems solved by technology

[0003] At present, there is no precise parameter limit for the processing technology of daily-use ceramic tableware blanks. The quality of blank production depends entirely on the experience of operators, and the production quality of blanks directly determines the pass rate after firing and the effect of glazing. Therefore, It is necessary to strictly control the processing technology of the green body to ensure the processing quality of the green body and reduce the economic loss caused by the quality of the green body.

Embodiment 1

[0027] (1) Raw material preparation: mix 50kg of kaolin, 10kg of clay, and 15kg of feldspar powder, add 0.5kg of nano-titanium dioxide and 0.5kg of molecular sieve raw powder, fully mix, and use a pulverizer to make coarse powder and fine powder into a particle size of 50 The target powder is then subjected to dry magnetic separation using a magnetic separator to remove iron, and the billet powder is obtained;

[0028] (2) Slurry preparation: add 60kg of billet powder into 300kg of water, make a slurry with a particle size of 100 mesh after refining, and use a magnetic separator to further remove iron through wet magnetic separation;

[0029] (3) Mud filtration and dehydration: the above-mentioned prepared mud is passed through a 120-mesh vibrating screen, and the resulting filtrate is sent into a bag filter press for dehydration through pressure filtration, and the water content of the gained mud after dehydration is controlled at 18-23%;

[0030] (4) Vacuum mud refining: the...

Embodiment 2

[0035] (1) Raw material preparation: mix 55kg of kaolin, 15kg of clay, and 10kg of feldspar powder, add 1kg of nano-titanium dioxide and 0.5kg of molecular sieve raw powder, fully mix, and use a pulverizer to make coarse powder and fine powder into a particle size of 50 mesh powder, and then use a magnetic separator to go through dry magnetic separation to remove iron, that is, the green powder;

[0036] (2) Slurry preparation: add 70kg of billet powder into 400kg of water, make a slurry with a particle size of 100 mesh after refining, and use a magnetic separator to further remove iron through wet magnetic separation;

[0037] (3) Mud filtration and dehydration: the above-mentioned prepared mud is passed through a 120-mesh vibrating screen, and the resulting filtrate is sent into a bag filter press for dehydration through pressure filtration, and the water content of the gained mud after dehydration is controlled at 18-23%;

Abstract

The invention discloses a technology for processing a green body of daily ceramic tableware and relates to the technical field of daily ceramics. The technology comprises the following steps: (1) preparing raw materials; (2) preparing mud; (3) filtering and dewatering the mud; (4) performing vacuum pugging; (5) cutting the mud; (6) forming the green body; (7) pre-drying the green body. According to the technology disclosed by the invention, by virtue of a manner of adding a small amount of nano titanium dioxide and crude molecular sieve powder into the raw materials, the thermal shock resistance of the prepared green body is obviously improved, and the problem that the green body produces cracks even fissures under continuous high-temperature raise conditions when immediately transferred into a kiln from a room temperature environment is solved; therefore, the yield of the fired green body is improved. Due to two-stage pre-drying treatment of the green body, the contained moisture is slowly volatilized, and the condition that the green body is directly transferred into the kiln to produce deformation due to sudden drop of the moisture content is avoided, so that the yield of the fired green body is further improved.

Description

Technical field: [0001] The invention relates to the technical field of daily-use ceramics, in particular to a processing technology of a daily-use ceramic tableware body. Background technique: [0002] Daily-use ceramics, also refers to tableware or home porcelain, as the name implies, refers to the indispensable daily life porcelain in people's daily life. The most important category of daily-use ceramics is ceramic tableware, which is widely used in daily life and is in great demand. The green body refers to the unfired device of the ceramic tableware. The processing technology starts from the selection of raw materials and ends with the pre-drying of the green body. [0003] At present, there is no precise parameter limit for the processing technology of daily-use ceramic tableware blanks. The quality of blank production depends entirely on the experience of operators, and the production quality of blanks directly determines the pass rate after firing and the effect of ...
