Problems solved by technology

[0003] However, since the beginning of the 21st century, with the continuous improvement of people's living standards, people have higher and higher requirements for daily necessities. The glorious history of the past has earned Longquan Celadon a lot of market share, but people are no longer satisfied. Based on the past history, it requires traditional famous porcelain to have various new functions that meet the requirements of the times
In the manufacture of daily-use porcelain and porcelain wine bottles, although the appearance of celadon has received great attention, the problem of low strength of celadon has seriously affected the expansion of the product market, especially in the process of transportation, loading and unloading due to collisions. causing unnecessary losses

Embodiment 1

[0018] The celadon ultra-heavy pressing one-time blanking process includes the following steps:

[0019] Preparation of raw material powder: ultramicronize the raw material;

[0020] Compression molding: mix the powder with rainwater, the mixing ratio of powder and mixed solution is 6:4, and press it into the desired shape under the pressure of 15-600MPa to obtain the pressed embryo. Mass production, reduce production costs, while increasing the strength of the embryo body;

[0021] Sintered compact: the sintering temperature is controlled at 1190~1300°C, and the ceramicization is sufficient;

[0022] Repair the embryo and get it;

[0023] Wherein, the mixed solution solvent is a mixture of calcium phosphate-sodium chloride-DETA, the mixing ratio of water-calcium phosphate-sodium chloride-DETA is 5:2:1:2, and the embryo body is light in texture, fine and hard, It is not easy to wear, crack, and gloss. Because the device reaction is nonlinear, the mechanism of action needs t...

Embodiment 2

[0029] The blank raw materials are evenly mixed according to the following ingredients and percentages: Longyan kaolin 35~45%, celadon clay powder 15~20%, potassium feldspar 8~20%, quartz 7~12%, hematite 3~8%, Zijin soil 5~10%, bone ash 6~10%, nanometer α-Al2O3 powder 9~15%, filler 5~10%.

[0030] Preparation of raw material powder: The raw material is subjected to ultramicronization treatment, and the particle size of the powder is controlled to be 950~1000 micron ultrafine powder;

[0031] Compression molding: mix the powder with rainwater, the powder and the mixed solution (water-calcium phosphate-sodium chloride-DETA, mixing ratio 5:2:1:2) mixing ratio is 6:4, under the pressure of 15-600MPa, press into The desired shape can be used to produce pressed embryos, which can shorten the time spent on embryo making by using heavy pressure molding, which can be mass-produced, reduce production costs, and increase the strength of the embryo body at the same time;

[0032] Sintere...

Embodiment

[0038] Example group: uniformly mix the blank raw materials according to the following ingredients and percentages: 35-45% of Longyan kaolin, 15-20% of celadon clay powder, 8-20% of potassium feldspar, 7-12% of quartz, and 3% of hematite ~8%, purple gold soil 5~10%, bone ash 6~10%, nanometer α-Al2O3 powder 9~15%, filler 5~10%.

[0039] Preparation of raw material powder: The raw material is subjected to ultramicronization treatment, and the particle size of the powder is controlled to be 950~1000 micron ultrafine powder;

[0040] Compression molding: mix the powder with rainwater, the powder and the mixed solution (water-calcium phosphate-sodium chloride-DETA, mixing ratio 5:2:1:2) mixing ratio is 6:4, under the pressure of 15-600MPa, press into The desired shape can be used to produce pressed embryos, which can shorten the time spent on embryo making by using heavy pressure molding, which can be mass-produced, reduce production costs, and increase the strength of the embryo b...

Abstract

The invention provides a celadon blank making technology through overweight pressure one-time moulding. The celadon blank making technology comprises the following steps of (1) preparing raw material powder; (2) performing compression moulding; (3) performing sintering on compressed blanks, wherein the sintering temperature is controlled to 1190-1300 DEG C; and (4) trimming the blanks so as to obtain the celadon blank. Raw materials for preparing the raw material powder comprise 35-45% of Longyan kaolin, 15-20% of celadon blank clay powder, 8-20% of potassium feldspar, 7-12% of quartz, 3-8% of hematite, 5-10% of Zijin clay, 6-10% of bone ash, 9-15% of nanometer alpha-Al2O3 powder, and 5-10% of filler. According to the celadon blank making technology disclosed by the invention, the refractoriness of blanks is greatly improved, besides, the made blank has the advantages of being high in strength, natural in glossiness, and fine in texture, and the celadon blank can be produced in batches, and the production cost is reduced.

Description

technical field [0001] The invention relates to a celadon blank-making process, in particular to a celadon super-weight pressing one-time forming blank-making process. technical background [0002] Longquan celadon rose in the late Tang and Five Dynasties, reached its peak from the Southern Song Dynasty to the Yuan Dynasty, and began to decline after the late Ming Dynasty. The production history lasted for thousands of years. It is a kiln with the longest firing time, the widest distribution and the greatest influence in the history of Chinese porcelain making. Tie. Longquan kiln produces a wide variety and high quality, especially famous for its "thousand peaks emerald color" and "ice-like jade" crystal glaze. For a long time, Longquan celadon has brought convenience and beauty to people's daily life. Over the long years, Longquan celadon, as the carrier of Chinese culture and economy, has traveled across the oceans and become a friendly envoy for cultural exchanges and ov...
