specific Embodiment approach 1

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings. As shown in the accompanying drawings:

[0019] A ceramic green body production method matching transparent frit dry particles, using 385-12250 kg each of kaolin, clay, quartz, potassium feldspar, albite feldspar, and talc with a particle size of less than 1 mm as raw materials for ceramic green bodies. Add an appropriate amount of water to the ceramic green body raw material, and add alkali, water glass, and sodium tripolyphosphate equally as a water reducing agent, and the amount of the water reducing agent added is 0.3-0.5% of the ceramic green body raw material , after being ball-milled into a slurry by a ball mill, it is spray-dried to make powder, and the moisture after the spray-dried powder is 5.5-6.5%, and then hydraulically formed by an automatic hydraulic machine, and then dried in a drying kiln to obtain a composition range of SiO 2 66-75%, Al 2 o 3 15...

specific Embodiment approach 2

[0024]Carry out according to specific embodiment 1, just as shown in the accompanying drawing of description, just: this ceramic green body production method of matching transparent frit dry grain, with particle size less than 1 millimeter kaolin, clay, quartz, potassium feldspar, albite , Talc is mixed as ceramic green body raw material, in described ceramic green body raw material, add appropriate amount of water, and evenly add alkali, water glass, sodium tripolyphosphate as water reducing agent, the quantity of adding described water reducing agent is 0.3-0.5% of the ceramic green body raw material is ball milled into a slurry and then spray-dried to make powder. The moisture after the spray-dried powder is 5.5-6.5%, and then hydraulically formed by an automatic hydraulic machine, and then dried Kiln drying yields compositions ranging from SiO 2 66-75%, Al 2 o 3 15-25%, CaO+MgO 0.5-5%, K 2 O+Na 2 Ceramic green body with O 2-8%, water reducing agent 0-2%, and moisture ...

specific Embodiment approach 3

[0028] Carry out according to specific embodiment one, just as shown in the accompanying drawing of description, just: the ceramic green body production method of this matching transparent frit dry grain, the composition of ceramic green body is set as SiO 2 67.72%, Al 2 o 3 19.82%, CaO+MgO 2.62%, K 2 O+Na 2 O 5.37%, Fe 2 o 3 0.64%, TiO 2 0.21%, loss on ignition 3.62%, according to the composition of the ceramic green body, select black mud, kaolin, high-temperature sand, medium-temperature sand, low-temperature sand, potassium Sand and talc are used as raw materials for ceramic green bodies. Each batch weighs 35,000 kg. After mixing, add 0.4% sodium tripolyphosphate and 0.2% soda ash as water reducers, and add 0.55 times the weight of ceramic green body raw materials at the same time. The water is ball-milled in a ball mill into a slurry with a fineness of 0.5-1% of the sieve with ten thousand holes, and then sprayed and granulated to make a powder with a water cont...

Abstract

A method for producing green ceramics matched with transparent dry frit pellets relates to the technical field of building materials and includes the steps: selecting materials within the preset range of green ceramic components and standardizing process technology; mixing 385-12250 kilograms of kaolin, 385-12250 kilograms of clay, 385-12250 kilograms of quartz, 385-12250 kilograms of potassium feldspar, 385-12250 kilograms of soda feldspar and 385-12250 kilograms of soapstone which are smaller than 1 millimeter in granularity to form green ceramic raw materials; adding an appropriate amount of water into the green ceramic raw materials and equally adding water reducing agents comprising alkali, water glass and sodium tripolyphosphate, wherein the addition of the water reducing agents is 0.3-0.5% of that of the green ceramic raw materials; ball-milling the materials into slurry by the aid of a ball mill and then spraying and drying the slurry to form powder containing 5.5-6.5% of water; and performing hydraulic forming prior to drying to produce the green ceramics with the range of components including 66-75% of SiO2 (silicon dioxide), 15-25% of Al2O3 (aluminum oxide), 0.5-5% of CaO (calcium oxide)+MgO (magnesium oxide), 2-8% of K2O (potassium oxide)+Na2O (sodium oxide), 0-2% of water reducing agents and less than 0.5% of water. The method is used for producing the green ceramics matched with the transparent dry frit pellets.

Description

technical field [0001] The invention relates to a ceramic green body production method for matching transparent frit dry granules, and relates to the technical field of building materials; in particular to the technical field of glass ceramic building materials; especially to the technical field of production methods for glass ceramic building materials; in particular to ceramics matching transparent frit dry granules Technical field of green body production methods. Background technique [0002] In the process of making glass ceramics, ceramic green bodies that match the transparent frit dry particles are inseparable. It is the carrier of glass ceramic products and one of the important factors that determine the quality of glass ceramic products. As far as the production of ceramic green bodies is concerned, it can be said to be varied and different at present, so its quality can be imagined, which can be said to be uneven and misleading; There are no requirements for the ...
