Description

Technical Field

[0001] The invention relates to the technical field of ceramics, and in particular to a method for manufacturing double-sided yin-yang finely carved Chinese white ceramics. Background Art

[0002] White porcelain is a kind of traditional Chinese porcelain. It is usually made of low-iron porcelain blanks, which are then glazed with pure transparent glaze and fired. Because there is no or only a very small amount of colorant in the glaze, the green blanks are glazed and fired in kilns at high temperatures to become plain white porcelain. White porcelain is loved by the general public because of its white color, which can reflect the color of tea soup. It can be made into daily necessities such as bowls, plates, cups, and lamps, as well as exquisite handicrafts, and can also be made into decoration and decorative items such as floors and lampshades. Therefore, it has a high application and collection value. At present, the surface glossiness of ceramic products is generally not high, which cannot meet the increasingly high aesthetic standards of consumers. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide a method for producing double-sided yin-yang finely carved Chinese white ceramics, and the produced ceramic handicrafts have high whiteness, good glossiness, excellent strength and good mechanical properties.

[0004] In order to achieve the above object, the present invention provides the following technical solutions: A method for making double-sided yin-yang finely carved Chinese white ceramics, comprising the following steps: S1: Use laser four-dimensional engraving system to carve the blank; S2: green body forming, cooling, glazing and inking; S3: Firing the inked ceramic body to obtain double-sided yin-yang finely carved Chinese white ceramics.

[0005] Preferably, in step S2, the temperature for forming the green body is 300-400° C., the forming pressure is 3-4 MPa, and the forming time is 8-10 s.

[0006] Preferably, the glazing in step S2 is glazing by dipping, and the ink application is dripping functional ink.

[0007] Preferably, in step S3, the temperature of the green body is raised to 600°C at a heating rate of 10°C / min, kept at that temperature for 1-2h, then raised to 1400°C at 2°C / min, and finally raised to 1600°C at 5°C / min, kept at that temperature for 4-6h.

[0008] Preferably, the glaze applied in step S2 comprises the following components in parts by weight: 15-18 parts of aluminum oxide, 15-18 parts of quartz, 16-18 parts of magnesium oxide, 8-10 parts of albite, 8-10 parts of barium sulfate, 5-8 parts of modified magnesium aluminum spinel, 15-18 parts of barium nitrate, 15-18 parts of sodium hydroxymethyl cellulose, 15-25 parts of kaolin and 80-100 parts of water.

[0009] Preferably, the preparation method of the glaze is specifically as follows: mixing the glaze components and then ball milling them, and then sieving them to obtain the glaze.

[0010] Preferably, the preparation method of the modified magnesium-aluminum spinel comprises: Magnesium aluminum spinel, lithium fluoride, polyvinyl pyrrolidone, 75% by volume ammonia water, KH570 coupling agent and anhydrous ethanol are mixed, magnetically stirred for 1-2 hours, and dried at 60° C. to obtain modified magnesium aluminum spinel.

[0011] Preferably, the weight ratio of the magnesium aluminum spinel, lithium fluoride, polyvinyl pyrrolidone, ammonia water, KH570 coupling agent and anhydrous ethanol is 20:1:20:40:20:50.

[0012] Preferably, the green body in step S1 comprises the following components in parts by weight: 25-40 parts of kaolin, 25-30 parts of quartz, 6-8 parts of sodium oxide, 6-8 parts of albite, 6-8 parts of barium sulfate and 5-8 parts of calcium oxide.

[0013] The invention modifies magnesium aluminum spinel and controls the melting temperature of lithium fluoride, firstly quickly heats up so that lithium fluoride enters an unstable semi-molten state and is evenly distributed on the surface of a green body, and at this time, organic matter used for modification on the surface of the ceramic green body slowly decomposes, and pores on the surface of the green body slowly migrate, so as to avoid excessive pores caused by the decomposition of organic matter and the separation between glaze and green body layers, and then continues to heat up at a low speed so that lithium fluoride is completely melted and melted into the green body from the surface of the green body through capillary action, so as to promote the densification of ceramics, and disperse at the grain boundary to prevent the subsequent firing and shaping from generating an amorphous phase, and finally, by gradually increasing the temperature in the later stage, the crystals formed by the external glaze and the internal crystal phase of the ceramic are pinned, so as to improve the stability and whiteness purity of the ceramic green body, thereby forming a double-sided yin-yang finely carved Chinese white ceramic through the shaping and fine carving of the white porcelain green body in combination with the glazing and ink dripping processes.
