Description
Technical field
The invention belongs to building ceramics technical field, and in particular to a kind of Ceramic Tiles produced using water-coal-slurry clinker
And preparation method thereof.
Background technology
Ceramic Tiles are through the tabular of technique productions such as being molded, sintering or block make pottery by clay and other inorganic non-metallic raw materials
Ceramic products.During producing Ceramic Tiles, powder generally use wet powder-making technique processed, i.e., with ball mill to each component in formula
Raw material adds that to carry out wet grinding mill comminution after water thin, then by mud by spray drying tower, the moisture in rapid evaporation mud droplet
And obtain powder.Spray drying tower needs hot-blast stove to provide heat, and hot-blast stove provides using water-coal-slurry as fuel to spray drying tower
While high-temperature hot-air, oneself will also discharge the clinker of slightly larger particle.Water-coal-slurry clinker is mainly by silica, aluminum oxide and one
A little metal oxide compositions.Processing for these clinkers, ceramics factory nearly all transport as industrial refuse and abandoned.
Generally, a small-sized ceramics factory can produce 5 tons or so of water-coal-slurry clinker daily, and medium-sized ceramics factory is daily
The water-coal-slurry clinker of 30-50 tons is produced, so substantial amounts of clinker is taken as industrial refuse to transport and abandoned, will certainly heavy damage ring
Border.In addition, water-coal-slurry clinker aluminum content is very high, the waste abandoned and can cause resource is transported.
The content of the invention
It is an object of the invention to provide a kind of using Ceramic Tiles of water-coal-slurry clinker production and preparation method thereof, to solve water
Environmental pollution and problem of resource waste caused by coal slurry clinker is abandoned.
Inventor is contrasted to the clinker of different producers, has obtained result as shown in table 1 below.
The clinker contrast of 1 different producers of table
| Imperfect combustion ratio | Aluminum content | Feature | |
| Gas generator clinker | 8-15% | <22% | Big block, black, hardly possible crushes |
| Hot-blast stove water-coal-slurry clinker | <2% | >=28% | Little particle, taupe, loosely |
The clinker that gas generator produces discharge contained coal component imperfect combustion at high proportion, and bulk is presented in outward appearance
Shape, black, hardly possible is broken, therefore can not be used directly in Ceramic tile adobe.
Hot-blast stove water-coal-slurry clinker present little particle, taupe, it is loose the characteristics of, easily grind processing.Water-coal-slurry clinker
Aluminum content is very high, and this is exactly the main component of Ceramic Tiles.On the one hand, the iron-holder of water-coal-slurry clinker is very high, can cause product embryo
Body color is deeper, but not to thering is the outward appearance of the Ceramic Tiles of glaze and use to have adverse effect on；On the other hand, water
Coal slurry clinker contains too high CaO, can have a negative impact to the physical property of Ceramic Tiles.Found by research, by reasonable
Formula composition can eliminate adverse effect in water-coal-slurry clinker caused by component, make the properties of ceramic brick product not low
In the requirement of national Ceramic Tiles GB4100/T-2015 standards.
The present invention is achieved by the following technical solutions：
A kind of Ceramic tile adobe produced using water-coal-slurry clinker, include the raw material components of following percentage by weight：
The main component of the high alumina mud includes：Al2O3>=28.5%, K2O≤1.5%, Na2O≤1.0%, add formula
The middle Al that can improve ceramic matrix2O3Content and intensity, improve its processability.
The high temperature sand is that main component is Al2O3>=19%, K2O≤1.5%, Na2The porcelain sand of O≤1.5%, due to this
Kind of raw material sodium containing potassium (KNaO) composition is relatively low, 1200 DEG C of temperature calcinations into sesame seed cake be not in obvious liquid phase, and sesame seed cake
Water absorption rate is higher (generally higher than 10%), if liquid phase need to occur, the temperature burnt till needs higher (to be such as raised to 1250 DEG C or more
It is high), therefore high temperature sand or high temperature feedstock are also commonly referred to as in ceramic industry.
The medium temperature sand refers to that main component is Al2O3>=16.5%, K2O >=4.5%, Na2The porcelain sand of O >=1.5%, by
It is higher in this raw material sodium containing potassium (KNaO) composition, 1200 DEG C of temperature calcinations into sesame seed cake there is obvious liquid phase, therefore
Medium temperature sand or medium temperature raw material are also commonly referred to as in ceramic industry.
The main component of the clay includes：Al2O3>=23%, K2O≤2%, Na2O≤1.0%, adding in formula to carry
The Al of high ceramic matrix2O3Content and intensity, improve its processability.
The main component of pot bank's press filt includes：Al2O3>=17.5%, Fe2O3>=0.8%, CaO >=3%, MgO
>=1%, K2O >=3%, Na2O >=2%, it is ceramics factory in sewage carries out decontamination process caused by itself, by it
In solids separated by squeezing mud machine or belt filter press, normally referred to as " press filt ".Added in ceramic formula
Press filt, the purpose of twice laid and environmental protection is also in order at, while firing temperature can also be reduced, reduce the cost of formula.
Preferably, the water-coal-slurry clinker is the clinker that goes out of cool water mixture burning heel row, institute in the hot-blast stove for produce Ceramic Tiles
The main component for stating water-coal-slurry clinker is：SiO245-56%, Al2O325-39%, Fe2O33.5-5%, TiO2 0.5-
2.0%th, CaO 5-10%, MgO 0.5-1.5%, K2O 0.5-1.5%, Na2O 0.5-1.5%, I.L1-2%.
It is further preferred that the present invention also uses the water-coal-slurry clinker of different ceramics factories, after testing its chemical composition such as table
2.As shown in Table 2, the chemical composition of two kinds of clinkers and content are essentially identical, are used equally for the preparation of Ceramic tile adobe.
The water-coal slurry furnace dreg chemistry composition of 2 different ceramics factories of table
Note：1# clinkers, 2# clinkers are clinkers caused by different ceramics factories
Using the preparation method of the Ceramic Tiles of water-coal-slurry clinker production, comprise the following steps：
(1) raw materials by weight meter mixes, and ball mill grinding is into mud；
(2) mud is spray-dried after crossing 200 mesh sieves, obtains powdery embryo material；
(3) powdery embryo material is transported to automatic brick machine after old and is pressed into Ceramic tile adobe；
(4) Ceramic tile adobe enters after roller belt drier drying carries out glaze spraying and stamp to its surface；
(5) again after roller kilns are fired, Ceramic Tiles are obtained.
Preferably, the old time is 24-48h.
Preferably, the temperature of the drying is 150~200 DEG C.
Preferably, the time of the firing be 45-70mim, temperature be 1170-1190 DEG C.
The Ceramic Tiles main chemical compositions that table 3 is produced using water-coal-slurry clinker
Beneficial effects of the present invention：
(1) present invention solves the problems, such as that ceramics factory's water-coal-slurry clinker is difficult to recycle, using water-coal-slurry clinker as original
Material is added in Ceramic Tiles, can not only be made full use of the resource in water-coal-slurry clinker, be reached the purpose of twice laid, can be with
Pollution on the environment problem is reduced, meets the theory of environmental protection；
(2) when the present invention adds the water-coal-slurry clinker no less than 5% in Ceramic Tiles, it is bad product quality will not to be produced
Problem, excellence rate reach more than 98%；
(3) present invention can utilize water-coal-slurry clinker caused by different ceramics factories (1# clinkers and 2# clinkers), reduce pottery
Porcelain garden industrial refuse transports the amount of abandoning；
(4) Ceramic Tiles are prepared in the present invention, and properties of product comply fully with state quality standard, have superior physico
Learn performance.
