Problems solved by technology

Due to the cumbersome process of filling mud in Nixing pottery, and the filling mud and the body of Nixing pottery do not absorb each other during the firing process, it is very easy to fall off, and the yield of finished products is extremely low, only about 20%, which seriously hinders the production of Nixing pottery in Qinzhou. Development of Xingpottery Filling Technology

Abstract

The invention discloses a manufacturing method for arranging white mud on a Nixing pottery green body in a filling manner. The manufacturing method includes the processes of blank preparation, green body forming, drawing, carving, mud filling, drying and firing. In the mud filling process, a layer of aluminum oxide powder and a layer of carboxymethyl propyl cellulose are evenly spread in a carved groove, and then the white mud is arranged in the carved groove in the filling manner; the white mud is obtained by mixing east mud and west mud according to the weight ratio of 7-8 to 2-3, and then the Nixing pottery green body is formed according to a manufacturing process of the blank; and in the drying process, the green body with the mud arranged in the filling manner is treated for 1 min to 5 min under the condition of 10 MPa to 15 MPa, and natural air drying is conducted. According to the manufacturing method, the electrostatic attraction of the white mud and the green body can be enhanced greatly by adding aluminum oxide particles, the molecular long chain of the carboxymethyl propyl cellulose has the involvement and crosslinking functions so that the white mud and the blank can be tightly bonded together, and the green body further has certain water retention uniformity so that water removal can be more even, and cracking and falling off are avoided.

Description

technical field [0001] The invention relates to a manufacturing method of Nixing pottery, in particular to a manufacturing method of filling white mud on a body of Nixing pottery. Background technique [0002] According to historical records, the mud-filling process of Nixing pottery in Qinzhou has been formed since the Qing Dynasty. The traditional mud-filling process of Nixing pottery mainly includes the following steps: 1) Preparation of blanks: The blanks are selected from the east of Qinjiang River, which crosses the urban area of ​​Qinzhou City. The soil in the area is commonly known as Dongni (soft clay with a yellowish-white color and contains a small amount of quartz sand, which plays a role in adjusting plasticity and bonding in the production process of Nixing pottery), and the soil in the west of the Qinjiang River is commonly known as Xini (contains a small amount of K 2 O, NaO, CaO, MgO, Fe 2 0 3 、TiO 2 , MnO 2 , is a kind of purple mudstone with high iron...
