Problems solved by technology

[0002] In the production methods of calcareous porcelain such as bone china and shell porcelain, due to the material characteristics of calcareous porcelain raw materials, two firing processes of high-temperature biscuit firing and low-temperature glaze firing are generally used, and the molding is difficult, the whiteness is poor, and the firing pass rate is low. Low, and it is difficult to use hand-painted decoration on the bisque body, prone to stroke defects or incomplete and uneven color rendering, blurred or faded pictures
The patent application document with the application number 200910230560.5 discloses a production process of calcareous porcelain in-glaze hand-painting, which discloses calcareous porcelain products formed by secondary firing, but the calcareous porcelain products produced by this method are The glossiness can only reach about 103, the whiteness can reach about 80%, and the qualified rate of fired finished products is only about 70%, resulting in high cost, high temperature, long firing time and high energy consumption

Embodiment 1

[0014] Embodiment 1, the underglaze color hand-painted production process of this kind of calcareous porcelain, adopts the following steps:

[0015] 1) Body porcelain shaping: The molded clay body is fired at 1100°C for 15 minutes to shrink and fix the shape of the body to make a porcelain body;

[0016] 2) Firing Xuan Porcelain: After spraying a layer of flux on the surface of the porcelain body, firing at 800°C for 15 minutes to make Xuan Porcelain. The composition of the flux is (in parts by weight): 32 parts of shell powder, 15 parts of feldspar powder, 28 parts of quartz powder, 10 parts of clay, 5 parts of magnesium oxide, 20 parts of water;

[0017] 3) Hand-painting: Use special coloring materials to create hand-painted creations on the surface of Xuan porcelain to make colored tires. When hand-painting, add water to the special coloring materials and mix thoroughly. The amount of water added is determined according to the color depth of the drawn pattern. (by weight):...

Embodiment 2

[0021] Embodiment two, the underglaze color hand-painted production process method of this kind of calcareous porcelain, adopts the following steps:

[0022] 1) Body porcelain shaping: the formed mud tire is fired at a temperature of 1280°C for 20 minutes to shrink and fix the tire shape to make a porcelain body;

[0023] 2) Firing Xuan Porcelain: After spraying a layer of flux on the surface of the porcelain body, firing at 850°C for 15-20 minutes to make Xuan Porcelain. The composition of the flux is (by weight): shell powder 35 20 parts of feldspar powder, 32 parts of quartz powder, 15 parts of clay, 10 parts of magnesium oxide, 30 parts of water;

[0024] 3) Hand-painting: Use special coloring materials to create hand-painted creations on the surface of Xuan porcelain to make colored tires. When hand-painting, add water to the special coloring materials and mix thoroughly. The amount of water added is determined according to the color depth of the drawn pattern. (by weigh...

Embodiment 3

[0028] Embodiment three, the underglaze color hand-painted production process method of this kind of calcareous porcelain, adopts the following steps:

[0029] 1) Body porcelain shaping: The molded clay body is fired at 1200°C for 18 minutes to shrink and fix the shape of the body to make a porcelain body;

[0030] 2) Firing Xuan porcelain: After spraying a layer of flux on the surface of the porcelain body, firing at a temperature of 830°C for 18 minutes to make Xuan porcelain. The composition of the flux is (by weight): 33 parts of shell powder, 17 parts of feldspar powder, 30 parts of quartz powder, 12 parts of clay, 8 parts of magnesium oxide, 25 parts of water;

[0031] 3) Hand-painting: Use special coloring materials to create hand-painted creations on the surface of Xuan porcelain to make colored tires. When hand-painting, add water to the special coloring materials and mix thoroughly. The amount of water added is determined according to the color depth of the drawn pat...

Abstract

The invention relates to a production method of porcelain and in particular relates to an underglaze hand painting production technique of calcium porcelain. The technique comprises the following steps: 1) body porcelain shaping: firing a clay body for 15-20 minutes, thus preparing a porcelain body; 2) Xuan porcelain firing: spraying a layer of flux on the surface of the porcelain body, and firing the porcelain body for 15-20 minutes, thus preparing Xuan porcelain; 3) hand painting: using special pigments to carry out hand painting creation on the surface of the Xuan porcelain, thus preparing a colored body; 4) finished product firing: carrying out biscuit firing on the colored body for 15-20 minutes, and then carrying out glaze firing for 10-15 minutes, thus preparing a finished product. The calcium porcelain product prepared by using the technique has high whiteness, glossiness and percent of pass, is low in production cost, and has the advantages of environment friendliness, energy conservation and high efficiency due to short firing time and low energy consumption.
