[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, ball milling can be used to pulverize the clay, flux and flux for 8-10 hours, wherein the total mass of clay, flux and flux: the mass of ball stones: the 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 ...
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] Wherein: clay (55 parts): purple sand shale, Niuxi village clay, the weight ratio of purple sand shale and 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 quality 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 ...
Embodiment 2
[0101] The raw materials of the ceramic formula in the present embodiment include the following components in parts by weight: 30 parts of Zisha shale, 30 parts of Niuxi village pottery clay, 20 parts of Zijinshan shale, 1 part of limestone, 19 parts of industrial waste residue (wherein ceramic fragments 3 parts, 16 parts of industrial waste). The nearby clay is Niuxi village clay, and the shale is Zijinshan shale.
[0102] Wherein: clay (60 parts): purple sand shale, Niuxi village clay, the weight ratio of purple sand shale and 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 quality 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, ...
