preparation example Construction

[0034] The preparation process of the body porcelain comprises the following steps:

[0035] Step 1. According to the above-mentioned parts by weight, mix each material in the main material to obtain a dry material, then add water 0.55-0.65 times its mass to the dry material, stir it evenly, send it to a ball mill, and ball mill it into a particle size It is 150~300 mesh slurry, for standby;

[0036] Step 2. According to the above weight parts, take the fish scale powder and sawdust in the pore-making granules and mix them evenly, then add a binder to the obtained mixed material, after evenly mixing, stick to PMMA with a particle size of 2-4mm The outer surface of the granules is made into pore-making granules with a particle size of 3-5mm, for use;

[0037] Step 3. After sieving and filtering the slurry prepared in step 1, the tire material is made, and then, adding 0.2-0.3 times its mass of ethanol and 0.03-0.05 times its mass of ethanol to the obtained tire material. Indu...

Embodiment 1

[0048] A kind of hollow Jun porcelain, including body porcelain and glaze porcelain. A plurality of through holes are arranged on the outer surface of the body porcelain. The treatment realizes the pre-separation of the pore-forming particles and the green body; and then sinters the green body at high temperature to realize the melting of the pore-making particles.

[0049] The firing raw material of the body porcelain is composed of main material and pore-making particles. According to parts by weight, the main material includes 30 parts of calcined kaolin, 40 parts of clay, 10 parts of soda stone, and 7 parts of volcanic stone , 3 parts of bone meal, 3 parts of purple wood knot, 0.06 parts of titanium dioxide, 20 parts of alumina, 10 parts of white feldspar, 10 parts of wind cave soil, 2 parts of black wool stone, 8 parts of iron ore Stone and 6 parts of carbon powder, the pore-making particles include 15 parts of PMMA pellets, 7 parts of fish scale powder and 11 parts of wo...

Embodiment 2

[0065] A kind of hollow Jun porcelain, including body porcelain and glaze porcelain. A plurality of through holes are arranged on the outer surface of the body porcelain. The treatment realizes the pre-separation of the pore-forming particles and the green body; and then sinters the green body at high temperature to realize the melting of the pore-making particles.

[0066] The firing raw material of the body porcelain is composed of main material and pore-making particles. According to parts by weight, the main material includes 40 parts of calcined kaolin, 48 parts of clay, 15 parts of soda stone, and 11 parts of volcanic stone , 5 parts of bone meal, 7 parts of purple wood knot, 0.08 parts of titanium dioxide, 25 parts of alumina, 15 parts of white feldspar, 12 parts of wind cave soil, 3 parts of black wool stone, 10 parts of iron ore Stone and 8 parts of carbon powder, the pore-making particles include 20 parts of PMMA pellets, 9 parts of fish scale powder and 14 parts of ...

Abstract

The invention relates to hollowed-out Jun procelian, comprising two parts, i.e., base procelian and glazed porcelain, wherein a plurality of through holes are formed in the outer surface of the base procelian; the pre-separation between pore-making granules and a green body is realized by means of microwave treatment on the pore-making granules evenly doped in the base procelian green body through the through holes; then, the green body is subjected to high-temperature sintering, so that the pore-making granules are melted, and the hollowed-out Jun procelian is obtained. After the hollowed-out Jun procelian and a preparation technology thereof, provided by the invention, are adopted, the preparation of the hollowed-out Jun procelian which is good in finished product hardness, high in molding rate and low in loss on ignition can be realized by means of a base procelian raw material formula, a base procelian firing method and improvement for a glaze formula and a glaze firing technology.

Description

technical field [0001] The invention relates to the technical field of ceramic production, in particular to hollow Jun porcelain and its preparation process. Background technique [0002] Jun porcelain originated in the Eastern Han Dynasty. It is one of the five famous kiln porcelains in the Song Dynasty. Famous for its unique kiln transformation art, it has the reputation of "gold is priceless and Jun porcelain is priceless" and "a family is rich, but it is not as good as a piece of Jun porcelain". With its simple shape, exquisite craftsmanship, complex glaze matching, the magical kiln transformation of "one color in the kiln, thousands of colors out of the kiln", lakes and mountains, clouds and mist, human beings, animals, flowers, birds, insects and fish, etc. Known as the first of China's "Five Famous Porcelains". [0003] In the preparation process of Jun porcelain, from material selection to firing finished products, there are dozens of production processes. Generall...
