Embodiment 1

[0026] Raw materials: 21% quartz sand, 33% potassium sodium sand, 17% Datong soil, and 29% washing mud.

[0027] Based on the ratio of the above raw materials, a manufacturing process of Hanyu porcelain is provided, comprising the following steps:

[0028] The first step: select raw materials and remove impurities;

[0029] The second step: take by weighing 21% of quartz sand, 33% of potash-sodium sand, 17% of Datong soil, and 29% of washing mud for subsequent use;

[0030] Step 3: Add quartz sand, potassium sodium sand, Datong soil, and washing mud to the ball mill in proportion, and add water according to the ratio of total raw materials: ball stone: water = 1:2:0.5, and mix ball mill for 12 hours. Made into finished mud; the main components of finished mud are 60% silicon dioxide, 20% aluminum oxide, 0.10% iron oxide, 0.25% calcium oxide, 0.20% magnesium oxide, 0.90% potassium oxide, 3.5% sodium oxide, Titanium dioxide 0.1%, burning loss 5%;

[0031] Step 4: Sieve the fi...

Embodiment 2

[0037] Raw materials: 23% of quartz sand, 31% of potassium sodium sand, 19% of Datong soil, and 27% of washing mud.

[0038] Based on the ratio of the above raw materials, a manufacturing process of Hanyu porcelain is provided, the manufacturing steps of which are the same as those in Example 1, and will not be elaborated here; the main component content of the finished mud made in the third step is up to silica 66%, aluminum oxide 24%, iron oxide 0.3%, calcium oxide 0.3%, magnesium oxide 0.3%, potassium oxide 0.95%, sodium oxide 1.7%, titanium dioxide 0.15%, loss on ignition 7.5%.

Embodiment 3

[0040] Raw materials: 22% quartz sand, 32% potassium sodium sand, 18% Datong soil, and 28% washing mud.

[0041] Based on the above-mentioned ratio of raw materials, a manufacturing process of Hanyu porcelain is provided, the manufacturing steps of which are the same as those of Embodiments 1 and 2, and will not be elaborated here; the main component content of the finished mud made in the third step is up to 2 Silicon oxide 65%, aluminum oxide 22%, iron oxide 0.19%, calcium oxide 0.27%, magnesium oxide 0.29%, potassium oxide 0.93%, sodium oxide 3.5%, titanium dioxide 0.12%, loss on ignition 7%.

[0042] Comparative examples one, two, three, can obtain from the composition of the finished mud of preparation, the content of finished mud in embodiment three is the closest to existing porcelain composition, so raw material content quartz sand 22%, potassium sodium sand 32%, Datong soil 18%, washing mud 28% is the best ratio of porcelain material formula.

[0043] To sum up: this...

Abstract

The invention discloses a formula of a Chinese jade porcelain material and a production process of the Chinese jade porcelain material. The Chinese jade porcelain material is prepared from raw materials of: 22% of quartz sand, 32% of potassium sodium sand, 18% of Datong soil, 28% of wash mud, and the production process comprises the steps of: performing ball milling on the raw materials in a ballmill to obtain finished mud, and performing sieving, pugging, blanking, fettling, low-temperature calcining and other processes for molding sequentially; 54% of the raw materials are selected from waste ore generated in the process of ore washing, and through recycling of tailing obtained after ore washing, 22% of quartz sand and 32% of potassium sodium sand in the tailing are used as the raw materials for the porcelain material, so that the porcelain material has stable performance and can effectively solve the problem of waste discharge of an ore washing company and the problem of thermal stability of porcelain during calcining of the porcelain; besides, no sulfur is discharged so that the environment can be protected, the quality is stable, and the cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of porcelain preparation, in particular to a Hanyu porcelain material formula and a manufacturing process. Background technique [0002] In the existing porcelain preparation process, the magnesia porcelain discharges more than 1% of sulfur during the firing process, and its thermal stability is not good, and the finished product is easy to crack in the later stage. However, imitation bone china has high requirements on the quality of raw materials. The existing raw materials of imitation bone china are all new ore soils, which are unstable in quality, high in price, and not environmentally friendly. All the use of new ore is costly, inefficient, and time-consuming. question. However, due to the shortage of mineral resources and the great damage to the mining environment, the tailings of many mining companies cannot be reused, which pollutes the environment and threatens the safety of people's property and ...
