Embodiment 1

[0020] Antique bricks produced from red mud are composed of the following raw materials in mass percentages:

[0021]

[0022] In addition, add 5% waste blanks of the mass sum of the above-mentioned materials.

[0023] Before using the waste billet, the waste billet is crushed into particles with a diameter of less than 2cm.

[0024] The raw materials are mixed and ground, and the grinding fineness of the mud is 250 mesh sieve, the remaining 5%, the firing temperature: 1170°C, and the firing cycle: 40 minutes.

[0025] Product testing indicators are as follows.

[0026] Product implementation standard: Appendix K of GB / T4100—2006, tested by the Bureau of Technical Supervision, the actual test data are as follows:

[0027]

[0028] According to this formula to make small cakes, the degree of sintering is high, and the color of the body after firing is dark red, which is darker than the red brick antique brick produced with purple sand soil, without deformation. Accordin...

Embodiment 2

[0030] Western-style tiles or cylinder tiles produced from red mud are composed of the following raw materials in mass percentages:

[0031]

[0032] The raw materials are mixed and ground, and the grinding fineness of the mud is 12% of the 250-mesh sieve. The firing temperature: 1100°C, and the firing cycle: 30 minutes.

[0033] According to this formula, make small cakes for trial firing, the color is brighter than the original product, the degree of sintering is high, and there is no deformation. This formula is used for production, and the production process parameters are controlled according to the original parameters. After testing, the products fully meet the national standards.

[0034] Due to the low temperature strength of red mud itself, the product has sufficient high temperature strength during the firing process by adjusting the process formula, the color of the green body produced is more vivid than the previous color, and all physical and chemical indicator...

Abstract

The invention relates to a method for producing architectural ceramic from red mud, belonging to the field of ceramic preparation methods. The invention is characterized in that the archaized tile produced from red mud is prepared from the following raw materials in percentage by mass: 10% of diopside, 27% of Laiyang soil, 15% of Mengyin feldspar, 15% of Laiwu feldspar, 10% of green coke, 8% of high-density porcelain stone and 15% of red mud; and waste billet which accounts for 5% by mass of the total materials is also added. The red mud is added in production, the technological formula can be adjusted to overcome the defects in the red mud, so that the raw materials containing red mud satisfy the technological requirements for producing ceramic tiles and tiles, and the product can satisfy the Chinese standard, thereby changing wastes into valuable substances, utilizing the waste, lowering the production cost and reducing the environmental pollution.

Description

technical field [0001] The invention relates to a method for producing building ceramics by utilizing red mud, and belongs to the field of ceramic preparation methods. Background technique [0002] Red mud, also known as red mud, is the industrial solid waste discharged after refining alumina from bauxite. Generally, it contains a large amount of iron oxide, and its appearance is similar to red soil, hence the name. Red mud is the polluting waste slag discharged when the aluminum industry extracts alumina. Generally, for every ton of alumina produced, 1.0 to 2.0 tons of red mud are incidentally produced. As the world's fourth largest producer of alumina, China discharges millions of tons of red mud every year. A large amount of red mud cannot be fully and effectively utilized, and can only be stacked in a large area of ​​storage yard, which occupies a large amount of land and causes serious pollution to the environment. Therefore, the development and utilization of red mu...
