Problems solved by technology

[0003] At present, there is still a lot of room for improvement in the technology of producing slabs. For example, for the later cold processing, there is a high requirement for the modulus of fracture of slabs. A low modulus of fracture will cause the finished slabs to be very brittle. The slab is easy to break when cutting, and the excellent rate is low, so the production cost has been high, which is also a key factor restricting the application of rock slabs in many fields

preparation example Construction

[0068] In addition, the present application also provides a method for preparing the above-mentioned rock slab powder, for example, may include the following steps: preparing the rock slab powder according to particle size distribution. Specifically, the blank slurry is dried to obtain the above particle gradation.

[0069] In an optional embodiment, the fineness of the blank slurry may be 0.5-0.8, such as 0.5-0.6, 0.6-0.7 or 0.7-0.8, preferably 0.5-0.6. The fineness of the slurry is about fine, which is more conducive to increasing the content of fine particles in the powder particle gradation.

[0070] In an optional embodiment, the moisture content of the blank slurry may be 33-36%, such as 33%, 34%, 35% or 36%. It is worth noting that a high moisture content of the blank slurry will lead to high energy consumption for spray granulation, and a low moisture content of the blank slurry will easily lead to uneven powder spraying.

[0071] In an optional embodiment, the speci...

Embodiment 1

[0098] This embodiment provides a slate, which is obtained by pressing and firing slate powder. The slate powder is obtained by drying the blank slurry.

[0099] Among them, the raw materials of rock slab powder are as follows: by mass fraction, Dongqing super white sand: 4 parts, Jinwei bentonite: 4 parts, selected talc: 2 parts, Dahe low temperature sand: 20 parts, Keyou ball clay: 20 parts, Taoyuan low-temperature sand: 20 parts, Huichang low-temperature sand: 8 parts, Weisheng high-alumina sand paste: 15 parts, Guangxi high-potassium sand: 4 parts, composite zirconium: 3 parts. By mass percentage, the chemical composition of the raw material is as follows: 66.1% SiO 2 , 21.36% Al 2 o 3 , 0.33% Fe 2 o 3 , 0.1% TiO 2 , 0.41% CaO, 0.72% MgO, 2.83% K 2 O and 3.24% Na 2 O, the balance is unavoidable impurities. The loss on ignition of the chemical components of this raw material was 5.21%.

[0100] The wet ball milling method is adopted, and the ball milling time is 1...

Abstract

The invention discloses rock plate powder, a preparation method and application thereof, a rock plate and a processing method thereof, and belongs to the technical field of ceramic tiles. The rock plate powder is prepared from the following components in percentage by weight: 0.5-1 percent of rock plate powder with more than 20 meshes, 20-25 percent of rock plate powder with more than 40 meshes, 62-69 percent of rock plate powder with more than 60 meshes, 73-79 percent of rock plate powder with more than 80 meshes, 18-23 percent of rock plate powder with 80-90 meshes and 2.8-3.5 percent of rock plate powder with 90-100 meshes. The proportion of fine particles in the rock plate powder is high, the fracture modulus of a rock plate product can be improved, and then later cold machining is facilitated. The preparation method can comprise the step of preparing rock plate powder according to grain composition. The rock plate powder can be used for processing rock plates. The rock plate obtained by pressing and firing the rock plate powder has good fracture modulus, and the superior rate of finished products is high.

Description

technical field [0001] The invention relates to the technical field of ceramic tiles, in particular to a rock slab powder, a preparation method and application thereof, a rock slab and a processing method thereof. Background technique [0002] At present, slate home furnishing is particularly popular. Many ceramic companies have transformed into slate production or have begun to transform into slate production. They can't just make traditional ceramic tiles. Rock slabs lead ceramic tiles to become planks in an all-round way. The production of slate is also an important factor for a ceramic company to enhance its brand height. The emergence of slate has also evolved a new industrial chain and new supply demand. It can be said that slate is an epoch-making product. [0003] At present, there is still a lot of room for improvement in the technology of producing slabs. For example, for the later cold processing, there is a high requirement for the modulus of fracture of slabs. ...
