At present, the indoor drying method, air drying method, and sun drying method are generally used to remove moisture from the green body. However, these methods are limited by weather conditions, not only the drying time is longer, but the product quality is also extremely unstable.
For large vessels with large pieces and thick walls, due to the high moisture content of the green body and the uneven shrinkage of the green body caused by water evaporation, the drying time is longer and more unstable, and it is very easy to crack and deform the green body Such losses will bring certain economic losses to the enterprise.

Embodiment 1
[0015] 1) Preparation of billet: mix 4000Kg of Dongni, 6000Kg of Xini, and 1Kg of SrO, and make a billet according to a conventional method;
[0016] 2) Forming of the blank: make the blank into 100 vases (height 100cm, maximum diameter 50cm);
[0017] 3) Drying the green body: using far-infrared radiation with a wavelength of 10 μm until the moisture content is not higher than 2%; the far-infrared radiation source is a far-infrared radiation plate, and the temperature of the far-infrared radiation plate is 80 ° C The distance from the green body is 10cm.
[0018] According to the statistics, 1 piece of dry body was deformed, 2 pieces were cracked, and the remaining 97 pieces were intact.
Embodiment 2
[0020] 1) Prepare blank: mix 6000Kg of Dongni, 4000Kg of Xini, and 2Kg of SrO, and make a blank according to a conventional method;
[0021] 2) Forming of the blank: make the blank into 100 vases (height 100cm, maximum diameter 50cm);
[0022] 3) Drying the green body: using far-infrared radiation with a wavelength of 30 μm until the moisture content is not higher than 2%; the far-infrared radiation source is a far-infrared radiation plate, and the temperature of the far-infrared radiation plate is 150 ° C. The distance from the green body is 20cm.
[0023] According to statistics, 0 pieces of dry body were deformed, 2 pieces were cracked, and the remaining 98 pieces were intact.
Embodiment 3
[0040] 1) Prepare blank: mix 5000Kg of Dongni, 5000Kg of Xini, and 1.5Kg of SrO, and make a blank according to a conventional method;
[0041] 2) Forming of the blank: make the blank into 100 vases (height 100cm, maximum diameter 50cm);
[0042] 3) Dry the body: use far-infrared radiation with a wavelength of 20 μm until the moisture content is not higher than 2%; the far-infrared radiation source is a far-infrared radiation plate, and the temperature of the far-infrared radiation plate is 120 ° C. The distance from the green body is 15cm.
[0043] According to the statistics, 2 pieces of dry body were deformed, 2 pieces were cracked, and the remaining 96 pieces were intact.

Abstract
The invention provides a method for dehydrating large Nixing pottery utensils. The method includes mixing BaO into body materials and manufacturing bodies; carrying out far infraredradiation on the bodies under the condition of the wavelengths of 10-30 micrometers until the moisture contents of the bodies are not higher than 2%. The temperatures of far infraredradiation sources are 80-150 DEG C.The distances from the far infraredradiation sources to the bodies are 10-20 cm. Radiation sources for far infrared radiation are far infrared radiation plates. Compared with the prior art, the method has the advantages that deformation and cracking of the bodies in drying procedures can be reduced to a great extent by means of far infrared radiation, and particularly obvious effects can be realized for large utensils.
Description
technical field [0001] The invention relates to a method for preparing pottery, in particular to a method for dehydrating large Nixing pottery vessels. Background technique [0002] Nixing pottery in Qinzhou, whose scientific name is purple clay pottery, is one of the four famous pottery in China together with Jiangsu Zisha pottery, Yunnan Jianshui pottery, and Chongqing Rongchang pottery. Nixing pottery is a wonderful flower in the culture and art of the Chinese nation. It has a very long production process, has great cultural collection value, and has strong practicality. The blanks used in Nixing pottery are fine and free of impurities, and the pottery drinking utensils made of pottery have a moderate density of pores, which can play a role in keeping drinks fresh. At the same time, Nixing pottery does not add any additives such as preservatives during the preparation process, and the finished product does not contain any toxic ingredients. It is very healthy and safe to...
