Description

A kind of big thin plate of low water absorption ceramics
Technical field
The invention belongs to industrial ceramics fields, and in particular to a kind of big thin plate of low water absorption ceramics.
Background technique
Ceramic thin plate is a kind of by the production work such as kaolin clay and the shaped, high-temperature calcination of other inorganic non-metallic materials The area of plate ceramic products made of skill, this kind of ceramic is generally smaller.
The big thin plate of ceramics industrial at present is usually used twice firing and is made, and process flow complexity is time-consuming, at This is relatively disposable high, and product water absorption rate is also higher than one-time sintering technology.Why common polished bricks are rarely used in exterior wall paving Patch, wherein critically important reason is exactly that polished bricks water absorption rate is higher than 0.5%, exterior wall wet combining, which is easy to degumming, causes ceramic tile to fall off now As being not suitable for north outdoor and paving the way.
So the water absorption rate of the area and reduction ceramic thin plate that increase ceramic thin plate becomes particularly important.
Summary of the invention
According to the above-mentioned deficiencies in the prior art, the purpose that the present invention realizes is: increasing area and the reduction of ceramic thin plate The water absorption rate of ceramic thin plate.The present invention solves its technical problem and is achieved through the following technical solutions.
A kind of preparation method of the big thin plate of low water absorption ceramics includes following process flow: and feeder feeds intake-and ball mill grinds Mill-dry powder tower powder-press compacting-drying-leaching glaze-ink-jet printed-kiln is once fired-cuts edging-polishing-cutting-and beats It is packed in library.
The ceramic thin plate includes that the raw material of following parts by weight is prepared:
Wherein, kaolin, Hainan mud, black mud and Laiyang soil have stickiness, can prevent blank cracking.
In the grinding steps, ball mill uses 35 tons of ball mill grindings, and Ball-milling Time is 14-15 hours, and fineness is 0.5-1 mesh, flow velocity 1.2-2ml/s, mud balance 1.67-1.73, the parts by weight of water are 32-40, moisture content number and feeding The number for each raw material that machine feeds intake is corresponding.
During the dry powder tower flouring technology requires, the parts by weight of different-grain diameter powder are as follows: 40 10-40 parts of mesh, 60 mesh 30-65 Part, 80 mesh≤20 part, 100 mesh≤15 part;The parts by weight of water are 6-8 parts.
In the press pressing step, press model KD6800, pressure 6000T, compressor operation face is added using electromagnetic eddy Heat;Upper mold plate temperature is slightly higher, it is ensured that when compacting powder, cope plate will not glue powder, to increase yield rate, compacting is remaining Leftover pieces accepted with Tobe and realize circulation and stress, there are three types of the sizes of slug press, respectively 2070mm × 1060mm × 5.1mm (75 model), 1665mm × 1115mm × 5.1mm (65 model), 1315mm × 1070mm × 5.1mm (45 model), 1315mm × 670mm × 5.1mm (35 model);
In the baking step, using microwave drying, microwave has that cycle of oscillation specific to electric field is short, penetration capacity By force, the features such as can produce specific effect with matter interaction, heat transfer direction is identical as moisture diffusion direction, has drying Rate is big, energy conservation, high production efficiency, uniform drying, clean manufacturing, Yi Shixian automation control and raising product weight etc. are excellent Point;
In the leaching glaze step, each substance is accounted in enamel frit makeing formula: frit 80%, kaolin 12%, zirconium silicate 7.2%, sodium tripolyphosphate 0.6%, cellulose 0.2% will reach fineness 325 with abrasive lapping 12~20 hours Mesh, sieves surplus ratio 0.5-1%, glaze slip specific gravity 1.84-1.88, and the parts by weight of water are 25-30 parts;
It is described it is ink-jet printed in, using roller printing;
It is described it is ink-jet printed in, the weight percent of each substance in stamp-pad ink ingredient are as follows: stamp-pad ink 60-70wt%, colorant powdered frit 30-40%wt, slurry specific gravity 1.3-1.4, flow velocity 3-4.5mL/s;
The kiln the firing step, it is ink-jet printed after ceramic idiosome into firing in 600 DEG C of kiln, kiln with 1 DEG C/ Min is warming up to after 1100~1200 DEG C, heat preservation 0.5~1.5 hour and drops to room temperature with 3 DEG C/min;
The cutting step is cut using laser cutting machine using radium-shine light beam, and radium-shine light beam can to substance To generate metaplasia effect and special two kinds of effect of reason, physics or chemical reaction are generated after substance transient absorption laser light, thus radium Penetrate trace and reach cutting purpose, using numerical controlled machinery laser cutting machine, realize hi-precision cutting, cut lengths be 2030mm × 1030mm × 5mm (75 model), 1630mm × 1085mm × 5mm (65 model), 1280mm × 1040mm × 5mm (45 model), 1280mm × 640mm × 5mm (35 model) cuts success rate up to 95%, and cutting remaining edging material will not be contaminated, arbitrarily Other size is cut into, realization makes full use of;
The cutting step is a kind of machine cut using high pressure water flow, under computer control using high pressure waterjet Workpiece can be arbitrarily chiseled and carved, and is influenced by texture material small, at low cost, easy to operate, cutting products quality is high, and water knife is that cold conditions is cut Cut, when cutting do not generate fuel factor, it is indeformable, without dross, without ablation, the physicochemical properties of material will not be changed, slot is small, In addition the characteristic of cooling cutting, can be improved stock utilization, cutting medium only has water and natural abrasive, does not produce in cutting process Raw other materials, are the cutting techniques of clean and environmental protection, after cutting, cut surface is neatly smooth, will not make to be cut in cutting process Cutting object has any damage to realize precisely cutting;
It being packed in storage after the completion of cutting, the size of the product is respectively as follows: 2000mm × 1000mm × 5mm (75 model), 1500mm × 1000mm × 5mm (65 model), 1200mm × 1000mm × 5mm (45 model), 1200mm × 600mm × 5mm (35 Model).
The invention has the advantages that: 1) ceramic one-time sintering technology reduce labour cost, reduces energy consumption, subtracts Few carbon emission amount, the ceramic thin plate water absorption rate of once-firing is low, adapts to the requirement of paving the way of different weathers, environment, mentions significantly High product specification;
