preparation example Construction

[0065] see figure 1 , the preparation method of the ceramic green body of an embodiment, comprises the following steps:

[0066] Step S101: Weigh the clay, flux and flux according to the weight of the formula, add water and ball mill to obtain a slurry; the process parameters of the slurry are: 1-1.5% of the residue after passing through a 250-mesh sieve, and a moisture content of 35-38% %, the viscosity is 150~200mpa.s

[0067] The uniform mixing of pulverized raw materials can make the particles of clay, flux and flux smaller, and the uniform mixing ensures the fineness of the slurry, making the size of the ceramic body shrink, and the firing temperature and performance are stable. Preferably, the clay, flux and flux can be ground by ball milling for 8-10 hours, wherein the total mass of clay, flux and flux: mass of ball stone: mass of water = 1:2:0.6. Ball milling is carried out in a closed machine, using wet grinding method to avoid flying dust and high grinding efficien...

Embodiment 1

[0085] Ceramic formula in the present embodiment, the raw material of ceramic formula comprises following component by weight part:

[0086] 30 parts of Zisha shale, 25 parts of Niuxi village clay, 25 parts of Zijinshan shale, 3 parts of limestone, and 17 parts of industrial waste. The nearby clay is Niuxi village clay, and the shale is Zijinshan shale.

[0087] Among them: clay (55 parts): Zisha shale, Niuxi Village clay, the weight ratio of Zisha shale to Niuxi Village clay is 1.2.

[0088] Flux (25 parts): Purple Mountain Shale.

[0089] Flux (20 parts): limestone, ceramic fragments, the weight ratio of the mass of limestone to ceramic fragments is 0.18.

[0090] Taking the preparation of ceramic floor tiles as an example, it includes the following steps:

[0091] Weigh the clay, flux and flux according to the parts by weight of the formula, put the clay, flux and flux into the ball mill for ball milling for 9 hours, wherein the total mass of clay, flux and flux: the qua...

Embodiment 2

[0101] The raw materials of the ceramic formula in this embodiment include the following components in parts by weight: 30 parts of purple sand shale, 30 parts of Niuxi village pottery clay, 20 parts of Zijinshan shale, 1 part of limestone, 19 parts of industrial waste residue (including ceramic fragments 3 parts, 16 parts of industrial waste). The nearby clay is Niuxi village clay, and the shale is Zijinshan shale.

[0102] Among them: clay (60 parts): Zisha shale, Niuxi Village clay, the weight ratio of Zisha shale to Niuxi Village clay is 0.67.

[0103] Flux (20 parts): Purple Mountain Shale

[0104] Flux (20 parts): limestone, ceramic fragments, the weight ratio of the mass of limestone to ceramic fragments is 0.33.

[0105] Taking flower pot preparation as an example, it includes the following steps:

[0106] Weigh the powder materials such as clay, flux and flux according to the weight of the formula, put the clay, flux and flux powder into the ball mill, fill the bal...

Abstract

The invention provides a ceramic formula, comprising, by weight, 55 to 65 parts of clay, 20 to 30 parts of a flux and 15 to 23 parts of a fluxing agent, wherein the clay is a mixture of purple sandshale and china clay mixed according to a weight ratio of 0.67 to 2.0, the flux is shale, and the fluxing agent is one or more selected from the group consisting of limestone, calcite, diopside, wollastonite, dolomite, talcum and industrial waste residue. A preparation method for a ceramic product comprises the following steps: weighing the clay, the flux and the fluxing agent according to the formula, carrying out crushing and screening with a 250-mesh sieve, wherein the weight of screen residue is 1 to 1.5%, adding water, carrying out blending to obtain slurry and then carrying out drying and granulation so as to obtain powder; grading particles and then carrying out molding so as to prepare a green body; carrying out drying so as to prepare a dry body; and carrying out firing so as to prepare a seasonal ceramic body. According to the ceramic formula and the preparation method for the ceramic product in the invention, raw materials are cheap, process is simple, firing temperature is reduced, production cost is decreased, investment for production equipment is lowered down, production efficiency is improved, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of ceramic materials, in particular to a preparation method of a ceramic formula and a ceramic product. Background technique [0002] The ceramic industry is an industry with high energy consumption, high pollution, high resource consumption and low output. In order to solve the problem of "three highs and one low", engineers and technicians in the ceramics industry have adopted measures to make building ceramics thinner and sanitary ceramics lighter. . [0003] Generally, enterprises will use high-grade raw materials as the formula for the ceramic body, because the AI ​​in the raw materials 2 o 3 The higher the content of the ceramic body, the higher the firing temperature of the ceramic body is. The firing temperature of the ceramic body formula in most ceramic factories is about 1300 ° C. Usually enterprises will take measures to widen and lengthen the kiln (generally up to 500 meters) to achieve the purpose of ...
