Technical Field
The invention relates to slurry in rock plate production, in particular to slurry for producing a digital slurry distribution decorative rock plate.
Background
The surface of the natural stone imitating ceramic tile has the effect of natural stone, and the patterns can be changed variously. With the continuous development of social economy, the requirements of people on living quality and living environment are continuously improved, so that the natural stone-imitating, simple and natural decorative material is deeply favored by people.
At present, various process means and materials are utilized to simulate the texture of natural stone in the market, and the method mainly starts from two aspects: on one hand, starting from the pattern formed by printing decoration, the pattern is formed on the glaze layer on the surface of the blank body by ink-jet printing, roller printing, silk-screen printing and other modes, and then a layer of transparent protective glaze is covered on the pattern. However, the decorative effect obtained by the ink-jet printing method is easy to be similar and easily simulated, and the ink for ink-jet printing and the printing oil for roller printing and screen printing are oily and cannot be used in too large amount, otherwise, the oily pattern is separated from the water-based protective glaze to generate glaze shrinkage, thereby generating defects. On the other hand, the fabric is started from the fabric on the upper layer of the blank body, the fabric can be divided into dry fabric and wet fabric, the dry fabric is generally obtained by stamping the dry fabric, molding the dry fabric by a press, then sintering the dry fabric and polishing the dry fabric, but the surface pattern of the prepared product is rigid and monotonous, the three-dimensional layering sense is not strong and unnatural, the wet method is adopted for distributing, the ceramic slurry is respectively sprayed on the green brick through the distributing pipeline to form the texture of the pattern of the imitated natural stone, the texture is often influenced by the pigment mixing effect of the ceramic slurry, the slurries with different colors are usually uniformly mixed, the layering effect of the color slurry is not obvious, the blending and mixing degree between the pigments is poor, the distribution trend of the slurry on the surface of the green brick is difficult to control, and the texture effect of the formed imitated natural stone is not clear, vivid, three-dimensional, fine and smooth enough, the pattern and line effect is single, and the transitional property is poor.

The moisture retention of the pulp is detected by two methods, wherein the first method for testing the moisture retention of the pulp can be called as a tilting method, and the specific operation is as follows: a piece of green body is taken, an inclination angle of the green body is set to be 6 degrees, a material without water absorption capacity, such as metal or plastic, is used as a barrier strip, a narrow channel with the width of 1cm, the height of 1.5cm and unlimited length is arranged, and 2mL of slurry is taken as a starting point at the highest position of a channel on the surface of the inclined green body for application. The length of the end point of the slurry flow from the starting point when the slurry no longer flows is tested as the flow distance of the slurry on the inclined green body by using the gravity action of the slurry. Because the unburned bricks have stronger water-absorbing capacity, therefore, the thick liquids can flow to the low of narrow passageway under the effect of gravity, but simultaneously because the stronger water-absorbing capacity of unburned bricks, also adsorbed by unburned bricks gradually and make some thick liquids fix in the original place, the thick liquids volume that flows downwards then reduces gradually, until no longer flowing, can regard as the detection method of thick liquids moisture retention with this, if the moisture retention of thick liquids is better, then the water-locking capacity is stronger, can keep the ability of flow of thick liquids more, and if the moisture retention of thick liquids is not good, then the water-locking capacity is weaker, moisture in the thick liquids just is adsorbed totally by unburned bricks very fast, and the flow distance is shorter naturally.

Specific gravity, flow rate, viscosity and surface tension are among the conventional physical property parameters, while the reynolds number, weber number and bond number are among dimensionless numbers. Where Reynolds number is a dimensionless number that can be used to characterize fluid flow, denoted Re, and is a measure of the ratio of inertial force to viscous force of a fluid, it can be expressed as follows: re = dv ρ/μ. In the invention, d is the diameter of slurry outlet, namely the diameter of slurry flowing through a pipeline, v is the slurry injection speed, ρ is the specific gravity of the slurry, and μ is the viscosity of the slurry, when the Reynolds number is small, the influence of viscous force on a flow field is greater than the inertia force, the disturbance of the flow velocity in the flow field is attenuated due to the viscous force, the fluid flow is stable and is laminar flow; 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 small change of the flow velocity is easy to develop and strengthen, and the turbulent and irregular turbulence is formed.
The Weber number, which represents the ratio of inertial force to surface tension effect, is denoted by We and can be represented by the following equation: we = ρ v2d/gamma. In the invention, rho is the specific gravity of the slurry, v is the spraying speed of the slurry, d is the slurry outlet diameter, namely the diameter of the slurry flowing through a pipeline, gamma is the surface tension of the slurry, and the smaller the Weber number, the more important the surface tension is, such as the problems of small scale as capillary phenomenon, soap bubbles, surface tension waves and the like. In general, the large scale problem, with a Weber number much greater than 1.0, the effect of surface tension is negligible.
The bond number is a dimensionless number determined due to the influence of surface tension, denoted by Bo, and can be represented by the following sub-formula: bo = ρ gd2And/gamma. In the invention, rho is the specific gravity of the slurry, g is the gravity acceleration, d is the slurry outlet diameter, namely the diameter of the slurry flowing through the pipeline, gamma is the surface tension of the slurry, the bond number represents the ratio of the gravity to the surface tension, when the action of the gravity is smaller than the surface tension, the surface tension plays a dominant role, and the liquid is spherical.
It should be noted that the slurry injection velocity v involved in the calculation of three dimensionless numbers, i.e., the Reynolds number, the Weber number, and the Bonder number, is not 10 to 25s of the flow velocity cup flow velocity of 50mL of slurry, and the flow velocity cup flow velocity of 50mL of slurry is 10 to 25s of the flow velocity cup flow velocity of 50mL of slurry, which means the time required for the 50mL of slurry to completely flow in the 50mL flow velocity cup under the action of gravity.
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 the fineness that d99 is not more than 0.85 mu m (the granularity of 99% of particles in the cumulative distribution of the 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 spray printing performance, more liquid dispersing agents, liquid stabilizing agents, liquid suspending agents, solvents 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%, and thus, the dimensionless numerical control of the Reynolds number, the Weber number, the Bangdard number and the like of the organic solvent type ceramic ink or the organic solvent type digital glaze is easier to control. The slurry for the digital slurry distribution system is water-based ceramic slurry, the fineness of the slurry is controlled to be about 45 mu m in d99 (the particle size of 99% of particles in the accumulated particle size distribution is not more than 45 mu m), most of the particle size of the slurry is more than 1 mu m, and the solid content of the slurry is not less than 60%, so that compared with organic solvent type ceramic ink or organic solvent type digital glaze, the water-based ceramic slurry has the advantages of coarser particle size, easier sedimentation of the slurry, difficult control of performances such as suspension and moisture retention, and larger control difficulty of dimensionless numbers such as Reynolds number, Weber number and Bunde number related to rheological parameters such as viscosity, surface tension, specific gravity and the like.
Compared with the fineness requirement of the traditional ink-jet decoration on the small-particle-diameter ink with the particle size not more than 0.85 mu m, the particle size of the slurry used in the production of the digital cloth pulp decorative rock plate can be expanded from the traditional 0.85 mu m to 45 mu m. The traditional ink-jet device is generally used for spraying and distributing oily ink, the ink needs to be ground to 0.85 mu m, if the traditional ink-jet device is used for spraying and distributing water-based slurry, the water-based slurry needs to be ground to 0.85 mu m, and based on the innovative design of a digital slurry distribution system, the slurry used in the production of the digital slurry distribution decorative rock plate only needs to be ground to about 45 mu m, so the power consumption generated by grinding can be obviously reduced, and the power consumption of each ton of slurry can be preliminarily estimated to be reduced from 2000-4000 degrees to 200 degrees.
In addition, if the slurry is ground too finely, other slurry rheology problems can arise. For example, thixotropy is obviously deteriorated, which may be because the temperature of the slurry is rapidly increased although the granularity of the slurry is gradually reduced along with the extension of the grinding time, so that the dispergator is partially failed, and the negative effect on the dispergator failure is more and more strong along with the extension of the grinding time, so that the thixotropy of the slurry is finally deteriorated; in addition, the grinding time is greatly increased, so that the temperature of the slurry is higher, a layer of solid layer is formed on the surface of the slurry due to the rapid evaporation of surface moisture in the standing process of the ground slurry, namely the common 'skinning' defect in the production process, the formed skinning is difficult to be completely broken through the stirring effect in the subsequent use process, solid aggregates are formed, the slurry is not uniform, and the presenting effect of the digital cloth slurry on the surface of the blank body is influenced.
According to the knowledge of fluid mechanics, the Reynolds number Re < 2300 is in a laminar state, Re < 2300 < 4000 is in a transition state, and Re > 4000 is in a turbulent state. Obviously, the slurry used in the production of the digital slurry distribution decorative rock plate is in a laminar flow state, on one hand, the slurry used in 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 with water, basic rheological performance parameters such as specific gravity, viscosity, flow velocity and the like are in a range, and the caliber of emergent slurry provided by a flow limiting mechanism in the digital slurry distribution system is smaller, namely the diameter d of the emergent slurry is smaller, so that the Reynolds number of the slurry used in 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 beneficial to the flow transmission of the slurry for the digital slurry distribution system in the slurry distribution device, once increasing the reynolds number will significantly affect the printing effect of the slurry on the surface of the blank, as mentioned in the first point, the slurry for the digital slurry distribution system is a water-based ceramic slurry formed by mixing and grinding minerals such as natural clay, feldspar, quartz, etc. with water, therefore, the reynolds number also has an upper limit, if increasing the reynolds number once, the solid content of the slurry needs to be significantly reduced, i.e. the water content of the slurry is increased, the pattern texture effect on the surface of the blank needs to be realized by the solid components in the slurry, if excessively pursuing a large reynolds number results in an excessively large water content of the slurry, so that the solid components attached to the surface of the blank are greatly reduced, it is difficult to realize the concavo-convex three-dimensional hierarchical texture, and the blank absorbs the water in the slurry to attach the solid components thereto, if too much moisture is absorbed, the green strength of the green body tends to be too low, and defects such as edge chipping, corner chipping, and cracking are likely to occur due to insufficient strength.
The Weber number represents the ratio of the inertia force to the surface tension effect, the slurry for the digital slurry distribution system needs to flow and transmit smoothly in the slurry distribution device, and a certain inertia force is needed to prevent the slurry from blocking in a pipeline.
The Bunde number represents the ratio of gravity to surface tension, the concave-convex three-dimensional texture on the surface of the blank is formed by arranging a plurality of small droplets on the surface of the blank according to the requirement of a preset texture, for each small droplet, if the gravity action is greater than the surface tension action, the small droplets are easy to be completely spread on the surface of the blank, the realization of fine texture is not facilitated, similar to pixels on a liquid crystal display screen, the more the pixels are, the clearer the image is, the less the pixels are, one block is formed, the more the image is blurred, if each small droplet is completely spread, the larger the overlapping is inevitable, macroscopically, the pattern formed by digital pulp distribution is blurred, and if the gravity action is less than the surface tension action, the small droplets are approximately spherical and can be combined with the blank at a certain wetting angle on the surface of the blank, so that more positions can be left for the small droplets sprayed on the back, similar to the situation that the number of pixels on the liquid crystal display screen is larger, the image is clearer, and the pattern formed by the digital cloth pulp is clearer and more stereoscopic when viewed macroscopically, so that the method is more favorable for forming a concave-convex stereoscopic texture layer. The number of the bonds of the slurry used in the production of the digital slurry-distribution decorative rock plate is 0.1-0.2 and 0.15-0.23 respectively, so that clear and three-dimensional pattern texture layers can be presented.
The invention has the beneficial effects that: the invention provides three slurry materials suitable for producing a digital slurry distribution decorative rock plate, after the slurry materials are applied to a digital slurry distribution system, on one hand, the organic combination printing effect of points, lines and surfaces can be perfectly realized on the same plane, on the other hand, the slurry distribution effect is different from the traditional plane superposition type slurry distribution effect, the natural texture decorative effect formed by the slurry distribution system has obvious concave-convex three-dimensional texture, the limitation that slurry materials with different compositions and/or colors can only realize linear type flow lines in the traditional slurry distribution system can be broken through, the lines of the slurry materials can also be randomly arranged, the combination of a plurality of spray head arrays in the digital slurry distribution system ensures that the texture of the natural-imitated stone material formed by slurry distribution is clearer, more vivid, three-dimensional and exquisite, the patterns and the line effects are more abundant, the gradual transition effect is good, and the problems that the patterns of the existing ceramic tile product are not natural and abundant enough, the patterns are not natural and abundant, The texture is not clear and vivid enough and the control of the pattern of the glaze pouring process in the production is difficult.
