Problems solved by technology

On the other hand, if the humidity gradient between the over-dried green body and the joint mud is too large, the diffusion speed of water from the joint mud to the green body increases, causing the mud to shrink violently and generate stress. At the same time, the water flow formed by the excessive diffusion speed It may drive some fine particles to embed into the bonding surface of the green body, block the capillary pores, prevent the continuous diffusion of water, and also cause the layering of thick and fine particles in the adhesive layer, and also affect the embedding of large particles into the green body, resulting in the loss of accessories

Abstract

The invention provides a production method for dry-joint sticking clay of Nixing pottery. The production method for the dry-joint sticking clay of the Nixing pottery comprises the following steps that 1 raw materials of, by weight, 3 to 4 parts of east clay, 3 to 4 parts of west clay, 1 to 2 parts of cordierite, 1 to 2 parts of mineral powders and 0.5 to 1 part of feldspar are weighted; 2 the east clay and the west clay are mixed and are ground into mud through a ball mill, filtering is conducted, clay laths are formed in a suppressed mode, vacuum pugging is conducted, decaying is conducted, and A clay material is obtained; 3 the cordierite, the mineral powders and the feldspar are mixed and are mixed into mud through the ball mill, filtering is conducted, the clay laths are formed in a suppressed mode, vacuum pugging is conducted, decaying is conducted, and B clay material is obtained; 4 the A clay material and the B clay material are mixed to the dry-joint sticking clay, and the water content of the dry-joint sticking clay is 10 to 15 percents. According to the production method for the dry-joint sticking clay of the Nixing pottery, the dry-joint sticking clay still has comparatively good liquidity under the condition that the water content is comparatively low, the adhesive strength is strong, the figurability is comparatively good, and moulding body drying and burning crazing can be reduced greatly.

Description

technical field [0001] The invention relates to a method for making pottery, in particular to a method for making Nixing pottery dry joint paste. Background technique [0002] Some Nixing pottery products cannot be molded at one time. The body and accessories of the body need to be molded separately, and then the body and accessories are bonded with joint mud to form a complete body. The most common ones are the bonding of the main body such as pots and cans and accessories such as mouths, handles, ears, and lid handles. Bonding can be divided into wet bonding and dry bonding. Dry bonding refers to bonding when the moisture content of the body and accessories is about 2%, while the moisture content of the joint mud is 25-27%. , and the moisture content of the joint mud differ greatly, and the drying shrinkage of the two is inconsistent, which will produce shrinkage stress and lead to cracking of the attachment. On the other hand, if the humidity gradient between the over-d...
