The natural stone is influenced by long-term geological motion and climate change and is mixed with associated minerals with other colors, so that high-end, natural and rich decorative effects are formed, and the natural stone is favored by people as a high-grade decorative material. However, the radioactive minerals associated with some natural stones may cause radioactive damage to human health; the natural stone affected by geological action and weathering has more defects such as impurities, cracks and the like, is easy to generate pathological changes, and has poor service performance. In addition, the natural stone is used as an unrenewable resource, is expensive and is difficult to enter common families; the transitional exploitation and processing of natural stones not only causes the exhaustion of rare and valuable stone resources, but also seriously damages the natural ecological environment.
Under the circumstances, products such as ceramic tiles and ceramic plates mainly based on stone imitation are continuously developed on the market. According to the definition of ceramic tiles of the national standard GB/T4100-. The general specification is 0.6m × 0.6m (upper surface area 0.36 m)2) 0.8 m.times.0.8 m (upper surface area 0.64 m)2) The maximum can reach 1.2m multiplied by 1.2m (the upper surface area is 1.44 m)2）。

It can be found that in the prior art, the cloth and semi-dry pressing are mostly adopted to form a sheet blank, and then the sheet blank is dried and fired to prepare a large-size sheet, while the wet-process glaze slurry is sprayed and applied after the formed blank is adopted, and the water-containing decoration process of re-decoration, drying and firing is not reported. Therefore, the decoration effect of the ultra-large thin porcelain plate is limited.
The anhydrous decoration process refers to a decoration process of powder/dry particle cloth decoration, full-digital non-aqueous ink jet decoration or a combination thereof adopted by the ceramic blank. The water-containing decoration process is a decoration process which at least adopts one of glaze and glaze with the water content of not less than 20 percent, screen printing glaze, roller printing glaze and water-based ink for decoration in one or more working procedures of the decoration process, and can be combined with powder/dry particle cloth decoration and non-water-based ink decoration.

In the above steps, the conventional control means in the prior art is adopted, unless otherwise specified.
In order to accomplish the second purpose of the invention, the ultra-large specification thin porcelain plate product with the electrothermal function is produced according to the steps.
As a further technical scheme, high-fire frits and/or corundum materials are introduced into the polishing glaze for the ultra-large thin porcelain plate with the anti-slip function in the step B, so that a mixed crystal phase of celsian and anorthite is generated in a polishing glaze layer of the ultra-large thin porcelain plate, and point-shaped hard protrusions are formed on the surface of the polishing glaze and are uniformly distributed, so that the good anti-slip function can be realized.
As a further technical scheme, the volume weight uniformity of each part of the ultra-large specification thin porcelain plate blank in the step C is good, and the volume weight difference between any two parts in the same ultra-large specification thin porcelain plate blank is less than or equal to 0.1g/cm3。
And C, the volume weight is calculated according to the national standard GB/T3810.3-2016 ceramic tile test method part 3: measurement of Water absorption, apparent porosity, apparent relative density and volume weight, volume weight is a quotient of the dry weight of the sample divided by the apparent volume (including pores). The performance of the invention is mainly used for measuring the densification degree of a semi-finished product after the thin porcelain plate blank is formed/dried and sintered. The volume weight of the blank after the ultra-large specification thin porcelain plate is pressed and formed without a die has extremely important significance, on one hand, the invention represents the densification degree of the blank after the ultra-large specification thin porcelain plate is formed, so that the blank can meet the requirement of the green strength of the subsequent process,meanwhile, the sufficiency of the reaction among the ultra-large specification thin porcelain plate blank powder particles is ensured in the firing process; on the other hand, by adjusting the die-free press forming process and the performance of the powder of the ultra-large thin porcelain plate blank, the volume weight difference between any two parts in the same ultra-large thin porcelain plate blank is less than or equal to 0.1g/cm3And the compactness of each part of the blank of the ultra-large specification thin porcelain plate is controlled to be uniform, so that the simultaneous shrinkage and densification of each part of the ultra-large specification thin porcelain plate can be realized in the drying and sintering processes, and the improvement of the flatness of the ultra-large specification thin porcelain plate after drying and sintering is facilitated.
The baking in the step F mainly has the following functions:
the method can solve the problems that the ultra-large specification thin porcelain plate blank is easy to damage and the like caused by adopting a water-containing decoration process, particularly wet glaze spraying decoration after the ultra-large specification thin porcelain plate blank is formed. The wet glazing application mode is generally suitable for ceramic tiles with small specifications (the general specification is less than 900mm multiplied by 900 mm) or ceramic tiles with large thicknesses (the general thickness is more than 6 mm), but cannot be directly applied to large-specification or even ultra-large-specification thin ceramic boards, because the weight of an ultra-large-specification thin ceramic board blank is much larger than that of the ceramic tiles with traditional specifications (even thicker ceramic tiles), although the ultra-large-specification thin ceramic board blank has certain green body strength after being dried, if the wet glazing method is adopted for glazing slurry spraying, microscopically, due to hydration, water molecules in glaze permeate into a crystal lattice frame of powder on the surface of the blank, mineral molecules in the powder on the surface of the blank react with water molecules to generate solvated particles, the dissolving process of the powder is promoted, the cohesive force between the powder on the surface of the blank is further reduced, macroscopically, the powder on the surface of the blank absorbs moisture and expands, the bonding strength of the surface of the blank is damaged, the green strength of the upper half part of the blank is reduced sharply, and a narrow strip-shaped conveying line (convenient for slurry recovery) is adopted during glaze spraying instead of a wide belt-shaped conveying line, so that the blank of a thin porcelain plate with an ultra-large specification is easy to deform and even exceeds the maximum deformation which can be borne by the blank to cause damage, especially damageWhen the specification of the ultra-large specification thin porcelain plate is from 900mm multiplied by 1800mm (the upper surface area is 1.62 m)2) Increase to 1600mm multiplied by 5200mm (upper surface area 8.32 m)2) This effect is more pronounced. After the baking process of the step F is adopted, the ultra-large thin porcelain plate blank has certain strength, and the hydration effect can be greatly weakened, so that the blank damage is greatly reduced.
And secondly, organic matters in the blank of the ultra-large specification thin porcelain plate can be discharged, and the surface quality of the ultra-large specification thin porcelain plate prepared after sintering can be improved. The temperature of the baking process in the step F is 500-800 ℃, the temperature stage is a preheating zone of a traditional kiln, various organic matters in the ultra-large thin porcelain plate blank are discharged at the stage, and if carbonate and sulfate exist, decomposition is also carried out, and gas is discharged; intermolecular crystal water is removed, the blank shrinks, and the weight loss is rapidly increased; the water with the clay structure is discharged; at around 573 ℃, the β -quartz in the blank transforms into the α -quartz crystalline phase with a concomitant volume expansion. Therefore, after the baking process of the step F, when the ultra-large thin porcelain plate blank enters the kiln to be fired, almost no physical and chemical changes such as organic matter discharge exist, the firing performance of the thin porcelain plate is stable, and the surface quality of the ultra-large thin porcelain plate prepared after firing is improved.
And thirdly, the decoration means and the decoration effect are enriched. The prior art mostly adopts the anhydrous decoration process of drying and firing after cloth and semi-dry pressing are molded into an oversized thin porcelain plate blank, and adopts the water-containing decoration process of spraying wet-process glaze slurry after the blank is molded, and then decorating, drying and firing, and the main reason is that the spraying of the wet-process glaze slurry easily causes various problems along with the great reduction of the thickness and the great increase of the specification of the porcelain plate, such as the reduction of the strength of the blank and the difficulty in meeting the requirements of the subsequent production process. Therefore, the decoration means and decoration effect of the ultra-large specification thin porcelain plate are limited. After the baking process of the step F of the invention is adopted, the thin porcelain plate can have certain strength (the modulus of rupture is more than or equal to 3 MPa), and the method is not only suitable for the anhydrous decoration process, but also suitable for the hydrous decoration process, thereby enriching the decoration means and the decoration effect of the ultra-large thin porcelain plate.
And fourthly, compared with the traditional biscuit firing process, the baking process in the step F of the invention also has obvious advantages. Bisque firing refers to a process of heat treatment of a green body at a certain temperature to make the green body have a certain mechanical strength. The biscuit firing temperature is 900-1100 ℃, the biscuit firing period is 50-100 min, and the biscuit firing temperature is high, so that the biscuit of the ultra-large thin porcelain plate has certain strength (the modulus of rupture is more than or equal to 10 MPa), the powder particles of the internal biscuit are also rapidly gathered, air holes are extruded, the structure of the biscuit is remarkably densified, the adsorption capacity of the biscuit of the ultra-large thin porcelain plate after biscuit firing on wet-process glaze slip is weakened, and the biscuit is not beneficial to implementation of large-dosage wet-process glaze slip and other water-containing decoration processes. Compared with the prior art, the temperature of the baking process is lower, the period is shorter, the baked ultra-large thin porcelain plate blank has a strong adsorption capacity to wet glaze slip besides a certain strength (the modulus of rupture is more than or equal to 3 MPa), and the method is suitable for wet glaze pouring and other water-containing decoration processes; on the other hand, compared with biscuit firing, the baking temperature is lower, the period is shorter, the energy consumption of the kiln is lower, the production flow is quicker and more efficient, and the production cost is obviously reduced.
The traditional wet-process glaze pouring manner is easy to have a 'water ripple' defect, especially for large-size products, and the defect is that after the specification of the product is increased, the matched glaze pouring equipment is increased in size along with the increased size to aggravate mechanical shock, and the glaze curtain area is increased along with the increased size to cause uneven glaze slurry distribution and the like to cause uneven glaze slurry distribution, so that the surface of the product after being polished has ripple-like fluctuation like water surface ripple, and the surface decoration effect is influenced. Secondly, the glaze slurry is applied on the ultra-large specification thin porcelain plate in a wet glaze spraying mode, so that the frame defect is easy to occur, namely the glaze slurry cannot be uniformly applied on the surface of the ultra-large specification thin porcelain plate blank due to the action of surface tension, so that local glaze accumulation is caused, and the frame defect is formed. Thirdly, if the wet glaze pouring form is adopted to apply the glaze slurry on the ultra-large thin porcelain plate, the defect of 'glaze curtain wire-drawing' is easy to occur, because the specification of the ultra-large thin porcelain plate is obviously larger than that of the traditional ceramic tile, when the wet glaze pouring application is adopted, the size of the glaze pouring equipment is inevitably enlarged, the glaze curtain with uniform distribution and components is difficult to form on the large glaze pouring equipment by the glaze slurry, the lump fake particles caused by a small amount of precipitation in the glaze slurry or the impurities left by the slurry pouring equipment are not completely cleaned, the defect of 'glaze curtain wire-drawing' is possibly caused during glaze pouring, then the local glaze-lacking defect is formed on the surface of the ultra-large thin porcelain plate blank, and the pit defect is formed after sintering.
The invention prepares the glaze slurry for the ultra-large specification thin porcelain plate with reasonable rheological property by designing and adopting the ultra-large shower plate with the diameter of the end face circle of the lower end not less than 2400mm, and better solves the problems. Aiming at the defects of 'water ripple' and 'frame', the invention is described by combining the attached drawings 1 and 2, the oversized glaze pouring tray designed by the invention comprises a glaze pouring cover a and a glaze distributing device b, wherein the glaze pouring cover a is composed of a glaze pouring cover main body cambered surface a1 and a glaze pouring cover end cambered surface a2, and the glaze distributing device b is positioned at the upper center of the glaze pouring cover a. Compared with the traditional shower tray, the oversized shower tray is mainly designed and improved from three aspects: firstly, the diameter d of the end face circle at the lower end of the glaze pouring cover a is not less than 2400mm, so that the size requirement of a once-fired ultra-large specification thin porcelain plate blank on a pouring disc for applying glaze slurry can be fully met; secondly, the arc radius R1 of the arc surface a1 of the glaze pouring cover body is designed to be 4300-5000 mm, the arc radius R2 of the arc surface a2 of the end part of the glaze pouring cover is designed to be 180-240 mm, the arc surface of the glaze pouring cover body is perfectly connected with the arc surface of the end part of the glaze pouring cover through the design of the arc radii of the arc surface a1 of the glaze pouring cover body and the arc surface a2 of the end part of the glaze pouring cover, a tangent line L1 is shared by the connection part, the included angle between a tangent line L1 at the intersection point of the arc surface of the main body of the glaze pouring cover body and the arc surface of the end part of the glaze pouring cover and a horizontal line L2 is adjusted, the included angle alpha of the two tangent lines is 10-20 degrees, when the glaze slurry for the ultra-large thin porcelain plate with the specification overflows to the upper surface of the glaze pouring cover a through the overflow edge of the glaze distributor b, the glaze slurry overflowing to the upper surface of the glaze pouring cover a has very uniform pressure and eliminates the internal bubbles of the glaze slurry, and can more smoothly flow to the edge of the end part 2 mm of the glaze pouring cover a through the arc surface of the upper body 1 of the upper body of the upper surface of the upper part of the glaze pouring cover a2, finally, wet-process glaze spraying and spreading are carried out on the ultra-large thin porcelain plate blank through the edge of the cambered surface a2 at the end part of the glaze spraying cover; thirdly, the width c of the cambered surface a2 at the end part of the glaze pouring cover is designed to be 80-120 mm, compared with the width of the cambered surface at the end part of the traditional tray glaze pouring cover, the width of the cambered surface at the end part of the glaze pouring cover is wider, the glaze slurry for the ultra-large thin porcelain plate is more smooth when passing through the cambered surface at the end part of the glaze pouring cover, and the glaze pouring speed on the surface of the ultra-large thin porcelain plate blank is easier to control. By combining the design improvements of the three aspects, the invention well solves the defects of 'water ripple' and 'frame'. Aiming at the defect of 'glaze curtain wire drawing', the invention strictly controls the working procedures of iron removal, sieving, storage and the like of the glaze slurry for the ultra-large specification thin porcelain plate by optimizing the process parameters of flow speed, specific gravity, viscosity and the like of the glaze slurry for the ultra-large specification thin porcelain plate, and frequently cleans related slurry applying equipment such as an ultra-large spray disc, a slurry barrel and the like, thereby finally well solving the problem of 'glaze curtain wire drawing'.
And (3) respectively adopting the wrapped red ink and the wrapped yellow ink as the red ceramic ink and the yellow ceramic ink in the step I. The existing yellow ceramic ink is prepared by mixing praseodymium yellow pigment with organic solvent, etc., however, the praseodymium yellow pigment has serious fading in the firing process after being prepared into the yellow ceramic ink, and the yellow ceramic ink shows light color development and greenish hue. The existing red ceramic ink is actually reddish brown ceramic ink, and the reddish brown ink adopts an iron oxide red pigment as a coloring agent, so that the color development is dark and not bright. Therefore, the red ceramic coating ink and the yellow ceramic coating ink are used for replacing the red brown ceramic ink and the yellow ceramic coating ink in the prior art, and the zirconium silicate crystals are used for coating the corresponding pigments in the red ceramic coating ink and the yellow ceramic coating ink.
However, since the coated red ceramic ink and the coated yellow ceramic ink are prepared by a coating process, and a layer of zirconium silicate crystal is coated on the surface of the corresponding pigment, the particle size of the coated red ceramic ink and the particle size of the coated yellow ceramic ink are both larger than that of the common ink particles, so that the coated red ceramic ink and the coated yellow ceramic ink are easy to precipitate. In view of the above, the present invention provides an improvement in the ink path system of a digital ink jet printer. The former equipment china ink bucket does not set up agitating unit, and the pottery ink just begins the stirring after being taken out the ink horn by the china ink bucket, leads to often having a large amount of precipitations in the china ink bucket. According to the invention, the stirring device is additionally arranged in the ink barrel, and the ceramic ink forms a loop from bottom to top in the ink barrel by adopting upward rotary stirring, so that the precipitation phenomenon is effectively eliminated. In addition, the ink path pipeline is changed from a small caliber to a large caliber, the circulation of the ceramic ink loop is accelerated, three filtering devices are additionally arranged, the proportion of large pigment particles entering the ink box is reduced, and the loss of the spray head is reduced.
The firing system in the step J needs to be correspondingly adjusted according to the produced thin porcelain plate, particularly, after the thickness of the ultra-large thin porcelain plate is further reduced, in the temperature rise stage of the firing process, because the temperatures of all sections of the kiln are different and the specification of the ultra-large thin porcelain plate is very large, when the ultra-large thin porcelain plate is conveyed and heated in a wide kiln by using a roller rod, a large longitudinal temperature difference is easily formed in the advancing direction of the ultra-large thin porcelain plate, namely, the temperature of the part of the same ultra-large thin porcelain plate close to the advancing direction of the ultra-large thin porcelain plate is higher, the temperature of the part of the same ultra-large thin porcelain plate is lower in the advancing direction of the ultra-large thin porcelain plate, and is just opposite in the temperature reduction stage, so that the large longitudinal temperature difference is formed on the same ultra-large thin porcelain plate, and the front end and back end of the ultra-large thin porcelain plate are not shrunk uniformly, the deformation is formed, the invention can well improve the shrinkage uniformity and the flatness after firing of the ultra-large specification thin porcelain plate by properly prolonging the temperature rising transition zone and the temperature reducing transition zone, namely realizing balanced temperature rising/reducing through a temperature rising system from a preheating zone to a firing zone and a temperature reducing system from the firing zone to a cooling zone, adjusting the air pressure and the excess air coefficient in the kiln and the like.
In the cooling stage of the firing process, if the stress exists in the ultra-large thin porcelain plate, the stress release of the ultra-large thin porcelain plate is not uniform, so that local cracking is easily caused, therefore, the valve opening of a quenching air pipe in a kiln quenching area cannot be over-extended, the quenching openings of the upper layer and the lower layer of a roller rod are approximately consistent, the temperature difference between the upper layer and the lower layer of the roller rod is reduced, the stress generated by inconsistent internal and external contraction in the blank cooling process is reduced, the defects of wind crack and the like of a product are avoided, the valve opening of a hot air pumping opening needs to be adjusted in a slow cooling area, the crystal form conversion of alpha-quartz to beta-quartz is stable, and partial stress is released as much as possible. Finally, the temperature difference between the upper layer and the lower layer of the roller rod can be controlled within 50-100 ℃, and the problem of cooling and cracking of the ultra-large thin porcelain plate is effectively solved.
As a further technical scheme, in the step J, the water absorption rate of the ultra-large thin porcelain plate semi-finished product is less than or equal to 0.5 percent, the failure strength is more than or equal to 800N, the modulus of rupture is more than or equal to 48MPa, and the volume weight is more than or equal to 2.25g/cm3。
And as a further technical scheme, after the edge grinding treatment in the step K, cutting a finished product to obtain the required specification and size of the finished product.
As a further technical scheme, after the edge grinding treatment in the step K, a polishing process is adopted for treatment. The surface of the ultra-large thin porcelain plate prepared by the method is subjected to required polishing treatment by changing the material quality and polishing process parameters of the grinding block, so that a semi-finished product of the ultra-large thin porcelain plate with a soft surface can be obtained, and the glossiness is 15-30 gloss units; or obtaining a semi-finished product of the ultra-large specification thin porcelain plate with a matte surface, wherein the glossiness is 5-15 gloss units.
And as a further technical scheme, in the step N, the pore size distribution range of the porous ceramic is 1 mu m-1 mm.
As a further technical scheme, the temperature control system in the step L can control the heating power of the graphene film, so that the temperature of the ultra-large thin ceramic plate with the electrothermal function is controlled to be between 30 and 50 ℃ when the ultra-large thin ceramic plate is stable, and the temperature control system is provided with safety protection devices such as overheating and overload devices, so that the graphene film is prevented from being abnormal in the working process.
The ultra-large specification thin porcelain plate with the electric heating function produced by the invention has the following beneficial effects:
compared with the prior art which mostly adopts an anhydrous decoration process, the invention innovatively introduces the baking process into the production method of the ultra-large specification thin porcelain plate, and can solve the problems that the ultra-large specification thin porcelain plate blank is easy to damage and the like due to the adoption of the wet glaze pouring hydrous decoration process after the ultra-large specification thin porcelain plate blank is formed.
