Embodiment 1

[0035] Pass 82g of Longquan local celadon mud powder through a 200-mesh sieve, mix with 3g of 120-mesh waste porcelain powder and 15g of 40-80nm nano-α-Al 2 o 3 The powder is mixed and stirred evenly, and the slurry is turned into a slurry and stale (as a grouting material for standby).

[0036] Then grouting molding, after demoulding and drying, the billet is repaired to replenish water, and after natural drying, it is bisque fired at 700°C for 6 hours. Heat at 1350°C for 1 hour and fire.

[0037] The flexural strength of the obtained product was 79.67mpa.

Embodiment 2

[0039] Pass 77g of Longquan local celadon mud powder through a 200-mesh sieve, mix with 3g of 120-mesh waste porcelain powder and 20g of 40-80nm nano-α-Al 2 o 3 The powder is mixed and stirred evenly, and the slurry is turned into a slurry and stale (as a grouting material for standby).

[0040] Then grouting molding, after demoulding and drying, the billet is repaired to replenish water, and after natural drying, it is biscuit fired at 800 ° C for 6 hours. After the bisque fired body is dipped in glaze and dried, it is fired in a high-temperature liquefied gas kiln with a maximum temperature of 1360 ° C. ℃ for 1 hour and fired.

[0041] The flexural strength of the obtained product was 88.25mpa.

Embodiment 3

[0043] Pass 70g of Longquan local celadon mud powder through a 200-mesh sieve, mix with 2g of 120-mesh waste porcelain powder and 25g of 40-80nm nano-α-Al 2 o 3 The powder is mixed and stirred evenly, and the slurry is turned into a slurry and stale (as a grouting material for standby).

[0044] Then grouting molding, after demoulding and drying, the billet is repaired to replenish water, and after natural drying, it is bisque fired at 800°C for 6 hours. After the bisque fired billet is dipped in glaze and dried, it is then fired in a high-temperature liquefied gas kiln with a maximum temperature of 1380 °C. ℃ for 1 hour and fired.

[0045] The flexural strength of the obtained product was 103.06mpa.

Abstract

The invention discloses a Longquan celadon reinforced blank. The Longquan celadon reinforced blank comprises the following components in percentage by weight: 12-25% of alpha-Al2O3 powder, 71-87% of celadon paste powder, and 1-4% of waste porcelain powder. The invention also discloses a method for preparing a product by sintering the Longquan celadon reinforced blank. Under the premise of not changing the characteristics of the traditional Longquan celadon formula, process technology, product style and the like, the invention prepares the Longquan celadon blank with high strength by utilizing alpha-Al2O3 new materials; and since the process technical route is fundamentally not changed, and the sintering and loading device and the sintering system are not changed, the damage rate of the products is greatly reduced due to the high strength of the products and the economical benefit is remarkable.

Description

technical field [0001] The invention relates to a Longquan celadon reinforced blank and a preparation method thereof, belonging to the production fields of Longquan celadon daily-use porcelain, architectural decorative porcelain, and packaging porcelain (wine bottles). Background technique [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...
