Description
Technical field
The present invention relates to ceramic big plate field, in particular to the big plate of the ceramics of a kind of high-intensity and high-tenacity and its preparation side
Method.
Background technique
" without big plate, not famous ", it is seen that when the fashion trend of the big plate of pre-ceramic (brick).In recent years, either in Italy
Bologna CERSAIE exhibition still each ceramic industry the relevant technologies seminar at home and abroad, even each large size ceramic equipment
And in the publicity of manufacturing enterprise, the big plate (brick) of ceramics and its molding equipment become most noticeable product without exception.Root
It is provided according to the standard of GB/T23266-2009, the big plate (brick) of ceramics refers to thickness no more than 6mm, surface area not less than 1.62m2's
Tile product.Compare for stone material, the big plate (brick) of ceramics has many advantages, such as, as homogeneous, intensity is high, isotropism,
Water absorption rate is low, anti-pollution is easy to clean etc..On decoration, with the maturation of ceramic production technology and ink-jet technology, the big plate (brick) of ceramics
Decorative effect have innovative progress, become rich and varied, exquisite exquisiteness, pattern pattern is stablized, and large area, whole is suitable for
The design of body effect is expressed, popular among consumers.Currently, big plate (brick) manufacturing equipment of ceramics can suppress 3~30mm of thickness not
Deng especially embodying bigger advantage on 3.5~6mm of thickness: low energy consumption, resource utilization are high, with general thickness
Ceramic big plate (with a thickness of 10~12mm) reduces by 84% or more compared to that can save raw material 60%, reduction energy consumption 50%, carbon emission.And
According to the difference of application places, thin plate is each has something to recommend him with slab, all are determined with the actual demand of market and application occasion.In state
Border Ceramic Tiles market, the big plate (brick) of ceramics have become the hot spot of high-end market.With the production of big plate, transport, paving, installation etc.
The application field of the continuous breakthrough of technological difficulties, the big plate (brick) of ceramics is more and more extensive, is no longer limited only to municipal works,
Application range is also expanded to the fields such as curtain wall, subway, screen, sales counter, artistic decoration, becomes a kind of widely applied novel decorative
Building materials.
In the prior art, CN107827435A has invented a kind of big plate of ceramics, including following raw material by weight: powder
Coal ash 35-60%, cullet 5-10%, kaolin 5-12%, foaming agent 0.1-0.5%, potassium feldspar 10-20%, albite 10-
