At present, the texture of natural stone is simulated by utilizing various technological means and materials in the market, and the method mainly starts from two aspects: on the one hand, patterns formed by printing decoration are firstly formed on a glaze layer on the surface of a green body in the modes of ink-jet printing, roller printing, screen printing and the like, and then a layer of transparent protective glaze is covered on the patterns. However, the decorative effect obtained by such a method of ink-jet printing is relatively easy to imitate and extremely easy to imitate, and the ink for ink-jet printing and the ink for roll printing and screen printing are oily and the amount of the ink used cannot be too large, otherwise, oily patterns are separated from the aqueous protective glaze to generate underglaze, thereby generating defects. On the other hand, the fabric is a dry fabric and a wet fabric, the dry fabric is generally obtained by stamping the fabric by a dry method, and polishing the fabric after being molded by a press, but the surface pattern of the manufactured product is dull and monotonous, the three-dimensional layering is not strong, and the fabric is distributed by a wet method, ceramic slurry is sprayed onto a rock plate blank by a distribution pipeline to form the texture of the imitated natural stone pattern, the texture is often influenced by the mixing effect of the pigments of the ceramic slurry, the uniform mixing of the slurries with different colors is usually carried out, the layering effect of the color slurries is not obvious, the mixing degree of the pigments is poor, the distribution trend of the slurry on the surface of the rock plate blank is difficult to control, and the formed imitated natural stone has the problems of insufficient clear and vivid texture effect, single pattern and line effect and poor transition property.
CN201310368652.6 discloses a ceramic tile decorating apparatus and a decorating method, the ceramic tile decorating apparatus of the invention adopts a glaze mixer to mix decorative slurries with different colors, and then the decorative slurries are sprayed on the surface of a green brick through a glaze spraying bell jar, and decorative slurries with different colors and mixing degree can be regulated by changing the flow velocity of the decorative slurries, and rich textures can be formed by matching with the speed change of a conveyor belt. Although the method has low cost and convenient modification, the formed patterns are not abundant, and the control is relatively difficult due to the fact that the flow patterns are the main ones.
Disclosure of Invention
The invention provides a production method of a digital cloth pulp decorative rock plate with an antibacterial function, which aims to solve the technical problems that the patterns of the existing rock plate product are not natural and rich, the textures are not clear and vivid enough and the patterns of the glazing process are difficult to control in production and endow the rock plate product with a good antibacterial function.
The invention also aims to provide the digital cloth pulp decorative rock plate with the antibacterial function, which is produced by the method.
In order to achieve the first object, the present invention adopts the following technical scheme: the production method of the digital pulp-distribution decorative rock plate with the antibacterial function is characterized by comprising the following steps of:
A. Preparing blank powder for later use according to a conventional method;
B. the slurry for the digital slurry distribution system is prepared by: weighing mineral raw materials according to the designed chemical composition of the slurry for the digital slurry distribution system, adding a certain proportion of dispergator, suspending agent and water for ball milling, and preparing the slurry for the digital slurry distribution system; the slurry for the digital slurry distribution system comprises 5% -50% of tea-stone;
C. and (3) forming: pressing and molding the green body powder prepared in the step A to form a digital slurry-coated decorative rock plate green body;
D. drying the green body: c, drying the digital pulp-distribution decorative rock plate blank body formed in the step C according to a conventional method;
E. digital cloth slurry: the digital pulp distribution system is adopted to apply the pulp prepared in the step B on the surface of the digital pulp distribution decorative rock plate blank body after the step D is dried according to preset textures;
F. and (5) drying again: e, drying the digital pulp distribution decorative rock plate blank body subjected to the digital pulp distribution in the step E again according to a conventional method;

Edging: and D, performing edging treatment on the semi-finished product of the digital cloth pulp decorative rock plate with the antibacterial function obtained by sintering in the step G by using conventional edging processing equipment to obtain the finished product of the digital cloth pulp decorative rock plate with the antibacterial function.
In the above steps, conventional control means in the prior art are adopted unless specifically described.
In order to achieve the second invention, the digital cloth slurry decorative rock plate produced according to the steps is adopted.
And B, the tea-stone is a pegmatite granite ore, under the long-term weathering geological effect, the tea-stone component contains various rare earth elements, the rare earth elements and the conventional oxide in the slurry for the digital slurry distribution system generate a composite activation effect, the multiband photocatalytic reaction under the conditions of visible light, ultraviolet light and the like is realized, and certain terahertz waves are released outwards through the vibration, coupling, rotation and the like among ions. Terahertz waves are electromagnetic waves between far infrared rays and microwaves, have strong penetrating power and radiation power, and are easily absorbed by objects to be converted into object internal energy. The terahertz wave can generate resonance with water molecules in the object after being absorbed by the object, so that the water molecules are activated, the combination between the water molecules and other molecules is increased, macromolecules such as proteins are activated, and the organism cells generate the highest vibration energy level. Because of the resonance effect, heat energy can be transferred to a deep subcutaneous place, so that heat generated by temperature rise is emitted outwards, capillary vessel expansion promotes blood circulation, enhances metabolism and regeneration capacity, and improves immunity. Meanwhile, terahertz waves have good antibacterial capability, mainly high-frequency electric fields change the membrane potential and polar molecular structure of bacteria, so that proteins and physiologically active substances in microorganisms are mutated and lose activity or die, and a good antibacterial and bactericidal effect is achieved.
The chemical composition of the tea crystal stone is as follows by weight percent: siO (SiO) 2 75%~78%，Al 2 O 3 12%~14%，CaO 0.5%~2%，MgO 0.01%~0.1%，K 2 O 4.5%~6%，Na 2 O 2.5%~5%，Fe 2 O 3 ≤0.1%，TiO 2 Less than or equal to 0.1 percent and the burning loss less than or equal to 0.5 percent. Besides the conventional oxide chemical composition, the theast also contains rare earth elements with relatively rich types. The rare earth oxide contained in the theaflavine is calculated according to the content of unit mass: la (La) 2 O 3 55~65mg/kg，CeO 2 125~135mg/kg，Pr 8 O 11 8~15mg/kg，Nd 2 O 3 35~45mg/kg，Sm 2 O 3 3~10mg/kg，Eu 2 O 3 ≤1mg/kg，Gd 2 O 3 3~10mg/kg，Tb 4 O 7 ≤1mg/kg，Dy 2 O 3 2~6mg/kg，Ho 2 O 3 ≤1mg/kg，Er 2 O 3 1~5mg/kg，Tm 2 O 3 ≤1mg/kg，Yb 2 O 3 1~5mg/kg，Lu 2 O 3 ≤1mg/kg，Y 2 O 3 20~30mg/kg。
And (C) adding pigment into the slurry for the digital cloth slurry system in the step (B) to prepare the slurry for the colored digital cloth slurry system.
Further, the specific gravity of the slurry for the digital slurry distribution system in the step B is 1.20-1.85 g/cm 3 The flow rate of the 50mL flow rate cup is 10-25 s, the viscosity is 40-500 mPa.s, the surface tension is 50-70 mN/m, the Reynolds number is 5-50, the Weber number is 70-130, and the bond number is 0.12-0.25.
Specific gravity, flow rate, viscosity and surface tension belong to conventional physical property parameters, while reynolds number, weber number and bond number belong to dimensionless numbers. Wherein the Reynolds number is a dimensionless number which can be used to characterize the fluid flow, expressed as Re, and is a measure of the ratio of the fluid inertial force to the viscous force, expressed as follows: re=dv ρ/μ. In the invention, d is the diameter of the slurry, namely the diameter of the slurry flowing through a pipeline, v is the slurry injection speed, ρ is the slurry specific gravity, μ is the slurry viscosity, when the Reynolds number is smaller, the influence of the viscous force on the flow field is larger than the inertial force, the disturbance of the flow velocity in the flow field is attenuated due to the viscous force, and the fluid flow is stable and laminar; on the contrary, if the Reynolds number is larger, the influence of the inertia force on the flow field is larger than the viscous force, the fluid flow is unstable, the tiny change of the flow velocity is easy to develop and strengthen, and the turbulence is formed.
The weber number represents the ratio of inertial force to surface tension effect, expressed as We, and can be expressed by the following formula: we=ρv 2 d/gamma. In the invention, ρ is the specific gravity of the slurry, v is the jet speed of the slurry, d is the diameter of the slurry, i.e. the diameter of the slurry flowing through the pipeline, γ is the surface tension of the slurry, and the smaller the Weber number is, the more important the surface tension is, such as capillary phenomenon, soap bubbles, surface tension waves and other small-scale problems. Generally, large scale problems, weber numbers well above 1.0, have negligible effect on surface tension.
The bond number is a dimensionless number determined by the effect of surface tension, denoted by Bo, and can be expressed by the following formula: bo=ρgd 2 /gamma. In the invention, ρ is the specific gravity of the slurry, g is the acceleration of gravity, d is the diameter of the slurry, i.e. the diameter of the slurry flowing through the pipe, γ is the surface tension of the slurry, the bond number represents the ratio of gravity to surface tension, and when the effect of gravity is less than the surface tension, the surface tension dominates and the liquid is spherical.
It should be noted that the slurry injection speed v involved in the three dimensionless number calculations of the Reynolds number, the Weber number and the bond number is not the 50mL flow rate cup flow rate 10-25 s of the slurry for the digital slurry distribution system, and the 50mL flow rate cup flow rate 10-25 s of the slurry for the digital slurry distribution system is the time required for the 50mL slurry for the digital slurry distribution system to flow under the action of gravity in the 50mL flow rate cup.
The traditional ink jet device adopts organic solvent type ceramic ink or organic solvent type digital glaze, and is characterized in that the granularity of the ceramic ink or the digital glaze needs to be controlled to be not more than 0.85 mu m (the granularity of 99 percent of particles in the cumulative distribution of granularity is not more than 0.85 mu m), and in order to ensure that the organic solvent type ceramic ink or the organic solvent type digital glaze has good jet printing performance, more liquid dispersing agent, liquid stabilizing agent, liquid suspending agent, solvent and the like need to be introduced, so that the solid content of the organic solvent type ceramic ink or the organic solvent type digital glaze is not more than 50 percent, and therefore, the Reynolds number, weber number, bond number and other dimensionless numerical control of the organic solvent type ceramic ink or the organic solvent type digital glaze is easy. The slurry for the digital slurry distribution system adopted by the application is water-based ceramic slurry, the fineness of the slurry is controlled to be about 45 mu m (the particle size of 99% of particles in the particle size accumulation distribution is not more than 45 mu m), and the particle size of the slurry is mostly more than 1 mu m, and the solid content of the slurry is not less than 60%, so compared with organic solvent type ceramic ink or organic solvent type digital glaze, the water-based ceramic slurry has coarser particle size, easier sedimentation, difficult control of suspension property, moisture retention and other performances, and larger control difficulty of Reynolds number, weber number, bond number and other non-dimensional numbers related to the rheological parameters such as viscosity, surface tension, specific gravity and the like.
According to the knowledge of fluid mechanics, the Reynolds number Re < 2300 is in a laminar state, the Reynolds number Re < 4000 is in a transitional state, and the Reynolds number Re > 4000 is in a turbulent state. Obviously, the slurry for the digital slurry distribution system is in a laminar flow state and limited to 5-50, and on one hand, the slurry for the digital slurry distribution system is water-based ceramic slurry formed by mixing and grinding minerals such as natural clay, feldspar, quartz and the like, the specific gravity, the viscosity, the flow speed and other basic rheological performance parameters are in a range, and the caliber of emergent slurry which can be provided by a current limiting mechanism in the digital slurry distribution system is smaller, namely the diameter d of emergent slurry is smaller, so that the Reynolds number of the slurry for the digital slurry distribution system is in a laminar flow state; on the other hand, although increasing the reynolds number of the slurry for the digital slurry distribution system is favorable for the flow transmission of the slurry for the digital slurry distribution system in the slurry distribution device, the increasing reynolds number can obviously influence the printing effect of the slurry on the surface of the blank, and referring to the first point, the slurry for the digital slurry distribution system is water-based ceramic slurry formed by mixing and grinding minerals such as natural clay, feldspar, quartz and the like, therefore, the reynolds number is also limited, if the reynolds number is increased, the solid content of the slurry needs to be obviously reduced, namely the water content of the slurry is increased, the pattern texture effect on the surface of the blank is realized by the solid components in the slurry, if the reynolds number is excessively pursued, the water content of the slurry is excessively large, the solid components attached to the surface of the blank are difficult to be greatly reduced, the concave-convex three-dimensional hierarchical texture is difficult to be realized, the blank is adhered with the solid components by absorbing the water in the slurry, if the excessive water is absorbed, the blank strength is easily caused to be excessively low, the defects such as edge breakage, cracking and the like are caused by insufficient strength.
The Weber number represents the ratio of the inertia force to the surface tension effect, and the slurry for the digital slurry distribution system needs to be smoothly flowed and transmitted in the slurry distribution device, so that certain inertia force is needed to prevent the slurry from being blocked in a pipeline.
The bond number represents the ratio of gravity to surface tension, the concave-convex three-dimensional texture on the surface of the blank body is formed by arranging innumerable small liquid drops according to the preset texture requirement, for each small liquid drop, if the gravity action is larger than the surface tension action, the small liquid drop is easy to be spread out on the surface of the blank body, and the realization of fine texture is unfavorable, like the pixels on a liquid crystal display screen, the more the pixels are, the clearer the image is, the fewer the pixels are, the more the image is blurred, if each small liquid drop is spread out completely, the small liquid drops are necessarily overlapped, the macroscopic view is that the pattern formed by digital cloth slurry is blurred, and if the gravity action is smaller than the surface tension action, the small liquid drops are approximately spherical, can be combined with the blank body at a certain wetting angle, so that more positions can be reserved for the small liquid drops sprayed on the back, the pixels similar to the liquid crystal display screen are more, the images are clearer, and the pattern formed by the digital cloth slurry is more favorable for forming the concave-convex three-dimensional hierarchy on the macroscopic view. The bonding number of the slurry for the digital slurry distribution system is 0.12-0.25, and clear three-dimensional pattern texture layers can be displayed.
Further, a step of applying base slurry is added between the step D and the step E, wherein the base slurry is prepared by weighing mineral raw materials according to the designed chemical composition of the base slurry, adding a certain proportion of dispergator, suspending agent and water and performing ball milling. The base paste is applied by adopting one of a spraying disc and a glaze spraying cabinet.
Further, the digital pulp distribution system in the step E comprises a computer control system and a pulp distribution device; the slurry distribution device comprises a nozzle array formed by combining a plurality of nozzles; the spray head comprises a filtering device, a digital flowmeter, a slurry distribution signal input end, a spray head cavity, an extrusion device, a buffer cavity and a flow limiting mechanism; the lower end of the extrusion device is made of transparent material, and an infrared signal generator is coated in the transparent material; the extrusion device is of a stepped bulge structure, each layer of steps are telescopic and movable, and the diameter of the bottom surface of the cylindrical bulge is smaller as the lower end of each layer of steps is closer to the lower end of each layer of steps; the inner wall of the buffer cavity is covered with a layer of hydrophobic film; the buffer cavity is of a stepped concave structure, and the diameter of the circular cavity is smaller as the buffer cavity is closer to the lower end; the extrusion device of the stepped bulge structure is matched with the buffer cavity of the stepped concave structure, so that the stepped printing effect with different gray scales can be realized; the flow limiting mechanism comprises a telescopic baffle and a flushing device; the upper end of the telescopic baffle is made of transparent silica gel, and an infrared signal receiver is coated in the transparent silica gel and is used for receiving an infrared signal sent by an infrared signal generator in the lower end of the extrusion device; the upper end of the flushing device is provided with a plurality of water outlets.
Further, the computer control system is used for controlling the slurry distribution device to distribute slurry according to preset textures.
Further, the nozzle array is a single-mode nozzle array formed by single rows of nozzles distributed in parallel at equal intervals, and can be suitable for pattern texture printing which is not particularly complex.
Furthermore, the nozzle array is a mosaic pattern nozzle array formed by double rows of nozzles distributed in parallel at equal intervals, and can be suitable for pattern texture printing with strong layering sense and fine textures.
Furthermore, the nozzle array is an interactive mode nozzle array with the cross distribution of the nozzles, and can be suitable for printing patterns and textures with rich colors, natural transition of colors and textures and gradual change.
Further, the filtering device is a screen, and the number of the screen meshes is 50-600 meshes.
Further, the filtering device is a screen, and the number of the screen meshes is 200-325.
Compared with the fineness requirement of the traditional ink-jet decoration on the ink with the small particle size of not more than 0.85 mu m, the distribution system in the production of the digital cloth pulp decorative rock plate can expand 0.85 mu m to 45 mu m, namely the digital cloth pulp system can be suitable for large-particle size pulp with the particle size of 45 mu m. While the conventional ink jet device is generally used for spraying oily ink, the ink needs to be ground to 0.85 mu m, if the conventional ink jet device is used for spraying Shi Bushui base slurry, the water base slurry needs to be ground to 0.85 mu m, and the digital slurry distribution system only needs to grind the slurry to about 45 mu m, so that the electricity consumption generated by grinding can be remarkably reduced, and the electricity consumption per ton of slurry can be reduced from 2000-4000 DEG to 200 DEG as estimated initially.
In addition, if the slurry is ground too finely, other slurry rheology problems can be introduced. Such as a significant deterioration in thixotropy, which may be due to the fact that the slurry has a particle size that gradually decreases as the grinding time increases, but the slurry temperature also increases rapidly, resulting in partial failure of the debonder, while the negative effect on the debonder failure becomes more intense as the grinding time increases, eventually resulting in poor thixotropy of the slurry; still another point is that the slurry temperature is higher due to the great increase of the grinding time, and the ground slurry forms a layer of solid layer on the surface of the slurry due to the rapid evaporation of surface moisture in the standing process, namely, the common skinning defect in the production process, and the formed skinning is difficult to be completely broken through stirring in the subsequent use process, so that solid aggregates are formed, the slurry is uneven, and the appearance effect of the digital cloth slurry on the surface of a blank body is affected.
Further, the filter device is a honeycomb ceramic.
Further, the digital flowmeter can display the flow rate of the slurry flowing into the spray head in real time, and feed the flow rate back to the computer control system, and then the computer control system adjusts the flow rate of the slurry. The slurry flow rate referred to herein is the weight/volume of slurry passing through the meter per unit time. If the flow rate of the slurry is monitored to be too small, the digital flowmeter can be adjusted through the computer control system, so that the flow rate of the slurry is properly increased, because the too small flow rate of the slurry can affect the stable slurry supply to the spray head, so that the printing effect is unstable, if the digital flowmeter is still not obviously improved after being adjusted, the slurry is possibly thick, or a slurry supply channel is blocked, such as a filter device is blocked, because large particle aggregates or impurities in the slurry block meshes of the filter device, and the filter device needs to be replaced or cleaned at the moment. If the flow rate of the slurry is monitored to be too large, the digital flowmeter can be adjusted through the computer control system, so that the flow rate of the slurry is properly reduced, and because the flow rate of the slurry is too large, the flow limiting mechanism is easily impacted by the large slurry, so that the arc of the slurry sprayed from the flow limiting mechanism is unstable, and the printing effect is affected.
Further, the extrusion device is made of transparent silica gel.
Furthermore, the hydrophobic film is mixed with silicon carbide high-hardness substances, so that the friction loss condition between the extrusion device and the inner wall of the buffer cavity can be effectively improved, and the service life of the buffer cavity is prolonged.
Further, the retractable baffle is one of a cuboid structure and a semicircular structure.
Further, the flushing device is one of a cuboid structure and a semicircular structure.
Further, the telescopic baffle and the flushing device are both of cuboid structures, and a flow limiting mechanism formed by the telescopic baffle and the flushing device is of a cross structure; the telescopic baffle and the flushing device are of semicircular structures, and a flow limiting mechanism formed by the telescopic baffle and the flushing device is of a petal-shaped structure.
Further, the opening and closing gap of the telescopic baffle is controlled continuously by 0-100%.
Further, the working process of the digital pulp distribution system is as follows: when a conveying belt on a rack bears a rock plate blank body and moves to the lower end of a pulp distribution device, a computer control system drives the pulp distribution device to distribute pulp on the surface of the rock plate blank according to an input preset pulp distribution pattern, the pulp is required to be filtered through a filtering device before entering a spray head, granular aggregates in the pulp are removed to prevent the spray head from being blocked, the pulp flows through a digital flowmeter and then enters a spray head cavity, when the liquid level of the pulp in the spray head cavity exceeds an inlet of a cache cavity, namely, the pulp flows into the cache cavity, a pulp distribution signal input end receives a digital signal given by a computer control system and drives an extrusion device to work, the extrusion device stretches out corresponding raised parts according to the pulp required by a preset gray level step, the pulp is extruded out of a current limiting mechanism, a telescopic baffle of the current limiting mechanism is also controlled by the computer control system, and the thickness and shape control of a line printed on the surface of the rock plate blank by adjusting an opening and closing gaps; when the infrared signal generator at the lower end of the extrusion device and the infrared signal receiver at the upper end of the telescopic baffle monitor that the spray head is blocked, the spray head stops working and enters a cleaning state, at the moment, the telescopic baffle is completely stretched out, the flushing device is closed, and water is discharged and flushed by a water outlet at the upper end of the flushing device until the flushing device is completely stretched out when the infrared signal generator at the lower end of the extrusion device and the infrared signal receiver at the upper end of the telescopic baffle monitor a dredging state, and the telescopic baffle is closed again and enters a working state again.
Further, a step of applying protective glaze is added between the step E and the step F.
Further, after the step H, a polishing process is used.
The beneficial effects of the invention are as follows: on the one hand, the traditional curtain coating type slurry distribution is characterized in that the whole surface of the slurry is covered on the surface of a green body in a superposition way, and the decoration on the surface of the green body is only limited to pure-color slurry after adding pigment; on the other hand, although the traditional cloth pulp texture formed by spraying a plurality of cloth pulp pipelines is improved to a certain extent compared with the spraying disc type cloth pulp, a plurality of pulp with different compositions and/or colors can be simultaneously applied on the surface of a blank, but the cloth pulp can only be positioned and distributed according to the preset pattern texture, namely, the linear type flow lines can only be displayed, the decorative effect is single, the layering effect of the color pulp is not obvious, the mixed degree of the pigments is poor, the distribution trend of the pulp on the surface of a rock plate blank is difficult to control, the texture effect of the formed imitated natural stone is not clear and vivid, the pattern and line effect are single, the transition property is poor, the digital cloth pulp system in the production of the digital cloth pulp decorative rock plate with an antibacterial function can input the digital pattern through a computer control system, and drives a pulp distribution device to conduct pulp decoration, on the one hand, the point, line and surface can be perfectly combined with the traditional plane surface by adopting the stepped printing design of spray heads, the traditional pattern and the current limiting mechanism can only realize the three-dimensional pattern, the three-dimensional pattern can be more clearly distributed, the three-dimensional pattern can be realized, the three-dimensional pattern can be more easily distributed, and the three-dimensional pattern can be more clearly combined, and the three-dimensional pattern can be more different in the pattern can be distributed in the pattern can be more different, and the pattern can be distributed in a three-layered by a three-plane, and the pattern can be different in a traditional pattern, and the pattern can be used for a spray pattern, and has a different color pattern.
